• Rob from the MintCast podcast is on the show tonight filling in for the nomadic and enigmatic Richard.

Announcements:

• The 2013 Dayton Hamvention is coming up May 17-19 in Dayton, Ohio. We are still in need of donations. Please keep ‘em coming.
• The Wouff Hong Podcast, member of the Black Sparrow Media Network, have released their first episode. If you don’t subscribe to the BSM aggregate feed, you can find them at the link above. Good episode, and they mention LHS.
• Rob and Russ use BeyondPod on Android as a podcast manager.
• Roy, KK4ATD, will be in Atlanta at RARSfest as an ambassador for LHS. If you’re anywhere near Raleigh, NC on Saturday, March 30, 2013, stop by and say hello. [LHS will NOT be present at RARSfest this year. Sorry for any confusion. -Ed]
• The sponsored ads in the right column of the LHS web site actually make us a not insignificant amount of money when you click on them. If you want to help us out without donating your own money, please click on an ad when you visit our site. We get money in our donation box, and you don’t lighten your own pockets. Thank you!

Topics:

• Visit KE8P’s blog. One of the articles documents using a Raspberry Pi as a temperature monitor.
• KK4ATD has developed Hamux, a 64-bit, CentOS-based Linux distribution with ham radio applications. This is a “live” CD image, so you can boot it from CD and try it before installing. At 698MB, it just barely fits on a CD.
• Our hosts embark on a brief digression about Douglas Adams.
• Slow Scan TV (SSTV)SSTV is a method of sending still images using radio frequencies on the HF bands. FSTV (fast-scan TV), which is typically done on VHF and UHF frequencies at distances up to a couple hundred miles, is similar to broadcast TV.

  In order to operate SSTV, you’ll need a radio (and a license to transmit), a computer, a sound card interface to connect them to each other, and software. For Linux, we have QSSTV. The current version is 7.1.7, released on January 4, 2012. It is compatible with the Ham Radio Control Libraries (hamlib) for controlling the radio.

  Russ gives a brief overview of the various configuration options and interface of QSSTV.

• Rob is not a ham, but has considered obtaining his license. Unfortunately, he lives in an area with deed restrictions that prohibit outside antennas. What are his options? There are several resources on the web for ham operation with antenna restrictions. Some of these are:
  • http://www.stealthamateur.com/
  • http://www.g4ilo.com/stealth.html
  • http://www.iw5edi.com/ham-radio/?attic-antennas,131

  Though in Rob’s case, with aluminum foil-lined roof tiles, attic antennas are not likely to work very well.

  Other possibilities: using EchoLink, IRLP, operating mobile or portable. Perhaps tossing up a temporary wire antenna in the back yard, operate, then take it down.

  Rob and Russ discuss the various options, potential for TVI, and VEC testing opportunities.

• Russ flies solo on LHS! Well, almost. Harrison, VE2HKW, fills in as co-host.

Topics:

• What’s in a name? Russ talks about the philosophical ramifications of the phrase “Linux distribution”, and referring to Linux vs. GNU/Linux. Richard Stallman prefers using GNU/Linux to refer to the operating system, and Russ seems to agree, but feels it doesn’t go far enough. Share your thoughts via the usual communication channels.
• hamqth.com is an alternative to QRZ.com for callsign lookups, and has an application program interface (API). Russ has programmed the gnorman bot in the LHS IRC channel to access hamqth.com. While in the chat, enter “.qrz some_callsign”, and gnorman will return the info.
• Another application that uses the hamqth.com API is QtLog. It’s mostly in German, but there’s enough English to allow you to use the program. It seems to require that you have a MySQL server running on the same computer. It also supports HamLib for rig control. You can use Google Translate to translate the website.
• Harrison offers an overview of oscilloscopes, including what they are, the controls, and how you might use one in your ham shack. There are several instructional videos available on W2AEW’s YouTube channel. (You can learn more about Alan, W2AEW, on his QSL.net page. There are also software-based oscilloscopes, like xoscope. Of course, you’ll need a hardware interface to the computer’s sound card.

• Happy Birthday, Richard!
• Yes, folks, it’s episode 100 of Linux in the Ham Shack. We’re now eligible for syndication!

Topics:

• In celebration of our 100th episode, several of our listeners in the chat room call in and participate in a roundtable discussion. Participants include Harrison (VE2HKW), Brian (K5BPC), and Jon (KT4KB). Unfortunately, noise on Jon’s connection prevented him from staying on the line.
• We received voice messages from listeners Michelle, Joy, Rich (KD0RG), Doug (N6LMX), Nick, Jon, “Major J”, and Harrison (VE2HKW).
• Feedback from Matt (KD8SZG), who asks which would be a better choice for a new HF user: a used IC-7000 or new FT-857D. The consensus is to choose the new FT-857D.
• Jon, KT4KB, asks how Russ and Richard met.
• Richard makes a shocking announcement!
• We have a short discussion of FreeDV vs. D-STAR, followed by a brief discussion of various Linux distributions.

Topics:

• Russ’ Raspberry Pi adventures continue. His Echolink node 54711 is now up and running on a Raspbian-based Raspberry Pi with svxlink and Qtel. Russ had to insert “dwc_otg.fiq_fix_enable=0″ into the /boot/cmdline.txt file in order to fix a problem with the onboard Ethernet card locking up. Since then, all has been well.
• Amateur Radio Pi is a forum with the tagline: The interactions between amateur radio and the Raspberry Pi.
• The Society for the Preservation of Amateur Radio (SPAR) will conduct a Winter Field Day, beginning 1700Z on January 26, 2013 and ending at 1700Z January 27th.
• HamSphere is a software Amateur Radio simulator that allows licensed radio amateurs and unlicensed enthusiasts to communicate with one another using a virtual transciever over the Internet. It was designed by Kelly Lindman, a radio amateur with callsign 5B4AIT. The software runs under Windows, Mac or Linux. There’s also a Wikipedia page for more information.
• RepeaterBook is an Android application for locating amateur radio repeaters. There are lots of options, including repeater types and modes (D-Star, etc). It also supports the BlueCAT Yaesu FT-857/FT-817 interface that allows you to tap a repeater entry in RepeaterBook on the phone and it will set your radio frequency.

Feedback:

• Comment via the Web site from Leif, KC8RWR, with another attempt at explaining hard and soft links, which we were discussing in episode 95. Thanks, Leif.
• Leif also commented about difficulties hearing a mobile radio without a speaker in the head unit.
• A very strange voice mail from the Radio Gangsta, aka Rich, KD0RG, from the LowSWR podcast.

• Welcome to another episode of Linux in the Hamshackedness, where the Chocolate Shake Fairy visits Richard.

Announcements:

• LHS now accepts micropayment donations via Flattr. It’s been successful for the Linux Outlaws guys, so we’re giving it a try here.
• We now have a countdown timer on the Web site that shows the time remaining until the next live recording. Of course, now that we’re recording on Wednesdays, we’ve decided to move back to Tuesdays. That will happen in January. Keep an eye on the web site for the dates. (Tuesday, January 8, 2013, as of this moment.)
• We also have a Google Community for Linux in the Ham Shack. It’s a great method for leaving feedback, show suggestions, questions, hate mail or anything else.
• The Dayton Hamvention 2013 will be coming up soon, so we’ve added the donation thermometer to the website. Please make a donation and help send LHS to Dayton again in 2013.
• Sign up for the LHS mailing list, too.
• Gnorman has a bio on the LHS About Us page.

Topics:

• Raspberry Pi in the Ham Shack
  • Russ has been working on getting an Echolink node running on his Raspberry Pi.
  • He’s chosen Raspbian as the operating system, which is based on Debian Wheezy.
  • Installation consists of downloading the iso, using dd to copy it to a secure digital card (SD flash memory card), booting the Raspberry Pi with the SD card, and following the prompts to install.
  • VK2MEV has posted instructions for configuring a Raspberry Pi as an Echolink node.
  • So far, Russ has Raspbian installed, as well as svxlink and qtel, but has not yet connected it to the usb sound card or attached it to his Rascal GLX interface to control the radio. Another option would be to use the Pi’s GPIO bus to control the radio instead of a digital mode interface.
  • VK2MEV also has a page describing WSPR on a Raspberry Pi. (Another page is VK2MEV’s blog on WSPRnet.)
  • Ted, WA0EIR, says he thinks some folks have his PSK31LX program running on a Raspberry Pi.
  • Russ mentions that there is a Slackware build for the Raspberry Pi.

Feedback:

• Cory, KD0QEA, asks if there are any “hangout” radio frequencies for LHS hosts and listeners. Well, Cory, there are none due to lack of time for the hosts to get on the radio. However, perhaps our listeners would like to establish an LHS net. Email your suggestions for bands, frequencies and times and we’ll announce them on the podcast. When Russ gets his Echolink node/Raspberry Pi running, he’ll be there more often. The node number will be 54711 (LHS11 on the telephone pad).
• Doug, N6LMX, left a voice mail about the Raspberry Pi. He has one and wonders which ham radio apps can be used on the Pi. He’s also using Raspbian as the operating system. Doug will be attempting to create a media center with his, as well as ham radio applications. Russ suggests running the Pi headless and using ssh from a smartphone or tablet to access it. That would avoid having to carry a monitor and keyboard around with the Pi. It’s likely that most of the popular Linux ham applications, such as fldigi, would work fine with the Pi, though you may need to compile them yourself. As for the media server idea, the Pi may not be quite powerful enough. Raspbmc is based on XBMC, and might be the best option. Ted, WA0EIR, has several Linux ham radio applications that should work quite well on the Pi. Richard also wonders if there are folks running APRS on the Pi, and there’s at least one. Thanks for the voice mail, Doug. We appreciate it.
• Dave, M0DCM, has been catching up on the show, and responds to episodes 95 and 96. He uses 75-ohm coax as a feedline with a 1:1 balun to horizontal and vertical dipoles, and is able to bypass his tuner on 21 and 24MHz. He goes on to describe his Linux and radio activities. Thanks, Dave.
• Thanks to everyone who sent happy birthday messages to Russ.
• Gorkon, aka Joel, says there may have been a problem with the ogg version of episode 96. Russ will take care of it if he finds the problem.
• Mike, from Sugarland, TX, has been trying to use N3FJP’s Amateur Contact Log (ACLog) program for logging, presumably under WINE, but it crashes and he wonders if anyone else has had any experience with this. If any of our listeners have tried ACLog under Linux, let us know, or respond on the Google+ LHS community. Russ suggests forcing WINE into 16-bit compatibility mode.

• Welcome to episode 95 of Linux in the Ham Shack. Episode 100 looms on the horizon, and we’d like to do something a little special. Call in to the LHS voice mail line at +1-909-LHS-SHOW (1-909-547-7469), or send an email, and share your thoughts about the show.
• LHS recommends this LOL Cat image.

Announcements:

• Kevin O’Brien, Publicity Director of the Ohio LinuxFest, is looking for someone to step up and take on the role of Volunteer Coordinator. If anyone is interested please reply to news@ohiolinux.org.
• We now digress into a ramble about censorship.
• On page 45 of the December 2012 issue of QST has an article on vertical vs. horizontal antennas, a topic we discussed in episode 91. In the same issue, on page 52, there is also an article about the NorthWest Digital Radio UDR56K, a topic we discussed in episode 90. Are we seeing a pattern here?
• Also in that issue is a description of several FCC Proposed Rule Changes, and our hosts discuss each of them:
  • Reduction of license expiration grace period from 2 years to 6 months.
  • Reduction of vanity call waiting period from 2 years to 6 months.
  • Reduction of the number of Volunteer Examiners at test sessions from 3 to 2.
  • Possible allowance of “remote testing” facilities using video and audio over a network that allows for proper administration of tests.
  • Allow single-slot TDMA transmissions.
• The 2012 Fort Wayne Hamfest is this weekend, November 17-18, in Fort Wayne, Indiana. This is also the ARRL Convention for Indiana. This launches Richard into reminiscing about the presentation of The Last Voice from Kuwait.

Topics:

• Symbolic (or soft) Links vs. Hard Links
  • Russ and Richard offer a discussion of the difference between soft, or symbolic, links and hard links in Linux.
  • A symbolic link is a pointer to another file name. Symbolic links can be created with the ln -s command:

    ln -s [original file] [link name]

  • Symbolic links can point to files on other volumes or file systems.
  • Hard links, on the other hand, are pointers to the data of another file, just like a directory entry is a pointer to the first block of data for the file. Hard links are also created with the ln command, but without the -s switch.
  • Hard links can only be used on the same file system.
  • A symbolic link is equivalent to a Windows shortcut, a pointer to the name of another file. A hard link is a reference to the data (first inode) of another file, and thus must be created on the same file system.
  • When the original file with associated hard links is deleted, the data remains until all of the hard links are also deleted. Deleting the original file with associated soft links will delete the file and the data, but the soft links will remain, now orphaned.
  • More information about links is available here.

Feedback:

• Listener Dave left a comment on the web site expressing his appreciation for the show, and also became a subscriber. Thanks, Dave!
• Jeremy, KD5HQN, also commented on the web site, claiming he’s actually learning something from the shows! He also corrected Richard about the proper location of Orthanc. Thanks, Jeremy.
• Bill, KJ4KNI, asked, via Richard’s Facebook page, for suggestions about the best Linux distribution for a beginner. (Linux Mint 13 is a good choice.) He also wonders why a ham might use 75-ohm RG6 coax as an antenna feedline. Our hosts discuss the possibilities.

• It’s the night before Halloween and we’re off to another spooky episode of LHS with our hosts starting with a ramble about horror movies. It’s a trick AND a treat!

Announcements:

• Please consider donating to the podcast or subscribing for #20/year. Also, the free Black Sparrow Media app is at risk of disappearing unless our listeners are willing to provide $15/month to keep the download site alive. Please contact us if you can help.

Topics:

• Creating a desktop wallpaper slideshow in GNOME:

  It’s actually a built-in feature of GNOME. Briefly, here are the steps:

  • As root, create a new directory in /usr/share/backgrounds (any name you want).
  • In that directory, place your desired background images (or links to them).
  • There’s already a directory in /usr/share/backgrounds called cosmos which you can use as a guide.
  • Copy background-1.xml from the cosmos directory into your new directory and edit it to specify your images.

  More information can be found in this askubuntu thread. Be sure to read through all the comments.

• Richard points us to one of many articles about ham radio operators helping out during and after Hurricane Sandy. Our sympathies to the victims of hurricane.
• More about EchoLink and Linux: Richard found the CQiNet project, which includes two applications, Echolinux (an EchoLink client for Linux) and The Bridge, an iLink/EchoLink compatable conference bridge. Of course, there is still the svxlink package, which includes the Qtel Echolink client.
• C’mon, people, where are my Raspberry Pi suggestions? Russ is still looking for good uses for his Raspberry Pis. Send your suggestions!
• Google Webfonts are open source fonts that can be embedded in Joomla, WordPress and others, embedded in CSS, or with Javascript. Visit Russ’ blog page for an example of Google Webfonts in action.

• The earth moved in Texas, recently, which sends Richard down memory lane.

Announcements:

• Texoma Hamarama will held October 26-27, 2012 at the Ardmore Convention Center in Ardmore, Oklahoma. Pre-registration ends October 20th.
• The Augusta Hamfest will be Saturday, October 13, 2012 in Augusta, GA.
• Scott, N8VSI, was the LHS ambassador at the Ohio LinuxFest, September 28-30, 2012. We look forward to hearing a report from Scott in the near future.

Topics:

• Richard recounts his experience replacing a computer power supply. Moral? Don’t be afraid to try repairing a computer yourself. Swapping parts is easier than you might think. For power supplies, pay attention to the wattage required. (Ed. Note: When in doubt, it’s best to replace the bad supply with one that has the same or greater wattage rating.)
• Departing from our usual topics, Russ and Richard discuss a couple applications for producing slide shows and panoramic photographs:
  • Imagination is a lightweight and simple DVD slide show maker for Linux and FreeBSD that’s very easy to use, offers a wide variety of transitions, supports background music, and much more. Available in the Debian and Fedora repositories, and probably many others.
  • Hugin is a program that allows you to assemble a mosaic of photographs into a complete, immersive panorama, stitch together any series of overlapping pictures, and much more. It’s cross-platform and easy to use.
• Why Ham Radio? Richard talks about why you might wish to obtain an Amateur Radio License and how you can combine it with Linux, including:
  • Getting your ham license for our non ham listeners.
  • There are many modes of communication, including voice, Morse code, and many digital modes.
  • The ease of getting your license.
  • Why you should get your license.
  • How to get your license.
  • The Amateur Radio Relay League (ARRL) is a good source of information
  • Free practice tests are available at qrz.com
  • A list of certified Volunteer Examiner Coordinators is available at www.ncvec.org.
  • Test sessions can be found through the ARRL and many local radio clubs.
• Russ describes Universal Plug ‘n’ Play devices (UPnP). Many new devices offer the ability to play media from UPnP servers. It makes sharing your media very convenient and easy, but can also be a security risk.

Feedback:

• Pete, VE2XPL, sends a long email in response to episode 88, and covers such things as the Toonie, Alexandre Graham Bell, Brad Sucks, the wAVEgUIDES PodCast, SouthCARS, email addresses for LHS, and the MintCast.
• Ted, WA0EIR, asked if there is a problem with the LHS mailing list as his attempts to post a message there “bounced”. Yes, the mailing lists have been broken, but they’re fixed now.
• Larry Bushey of the Going Linux podcast says thanks for the great show, and admits they stole the LHS “badger” sound effect for use on their show. Episode 185 contains an example of their use of the Badger.
• LHS was mentioned in a comment to a post at hak5.org.

Topics:

• HF Antennas, Horizontal vs. Vertical
  • Tonight, our hosts discuss the pros and cons of horizontally and vertically polarized HF antennas.
  • One thought is that once the RF radiation hits the various layers in the ionosphere, the polarization doesn’t really matter much as it gets reflected to and fro.
  • Richard offers the practical reason for preferring horizontal antennas for HF: it’s easier to build and erect the long antennas necessary for these frequencies. However, for chasing DX, those long-distance contacts, many hams prefer vertical antennas as they tend to have lower angles of radiation.
  • Also mentioned: GAP antennas and the G5RV antenna.
  • Wire horizontal dipoles are inexpensive and easy to construct. Verticals are a good choice when space is limited and can have a lower take-off angle, providing a good ground radial system is installed beneath them.
  • Horizontal antennas can be more directional. A dipole wire running north and south will have a better propagation east and west. A vertical is omnidirectional, radiating equally in all directions. To complicate matters, a horizontal antenna lower to the ground will radiate at higher angles than the same antenna that is higher. This can be useful for communicating with stations that are close to you.
• A new section of the podcast: Russ’ Rant!
  • Russ has a Yaesu FT-7900R, a dual-band UHV/VHF mobile radio. It has a removable front panel, allowing the main part of the radio to be hidden and the display can be easily mounted on the dash. However, the speaker is on the body of the radio, so you can’t hear it if it’s hidden under the seat or in the trunk! Russ thinks the head unit should also contain a speaker, perhaps a very small one like in an mp3 player. Or put the speaker in the microphone.
• Returning to antennas, Richard recommends that KD8SZG (in the chat room), should try building his own wire antennas for HF. Any of the antenna books written by Doug DeMaw, W1FB, are good resources. His Antenna Notebook is one. (I also like the various ARRL antenna books, like the Simple and Fun Antennas for Hams. -Ed.)

  • 25W 70cm Transceiver
  • 4800 to 56Kbps
  • FSK, GMSK, 4FSK
  • Open Source Linux Platform — a full Linux-based web server is built-in. It uses the Debian kernel, running on an ARM processor (faster than a Raspberry Pi).
  • Web Interface over Ethernet
  • 4 USB Host Ports
• Applications:
  • Winlink Email
  • APRS
  • D-RATS
  • D-STAR Digital Data
  • Digital Voice with AMBE Card Option

• The 10th Annual Ohio LinuxFest will be held September 28-30, 2012, at the Greater Columbus Convention Center in downtown Columbus, Ohio.
• Another riveting episode even though Richard has been attempting unassisted human flight. (We’re all worried about the consequences should he succeed.)
• Our special guest tonight is Rob Hawkins from the mintCast.

Announcements:

• If you’re a subscriber to LHS, you can access the Etherpad, download episodes without music, and you’ll soon have the option of episodes in .flac format.

• Please consider donating to the podcast! Click the Donate link.
• Check out the KF8GR Linux Ham Home Page. Even though it hasn’t been updated in several years, much of the information is still relevant.
• Richards suggests a Linux/Amateur Radio “best on the web” award. Your web site should have at least one page devoted to Linux or Linux and Ham Radio. Send your nominations to info@lhspodcast.info. If accepted, the LHS hosts will provide an award graphic for your website, and a link to your site from LHS.
• Richard also found this TechNewsWorld article “Why Ham Radio Is Still Handy”.

Topics:

• Interview with Rob Hawkins of the mintCast podcast.
• Rob describes his move from Ontario, Canada to Houston, TX, and drops this bombshell: “Texas is nothing like Ontario!” Rob is an engineer by training. His first computer encounter was an IBM 370 mainframe and Fortran at the University of Waterloo, Ontario. His first personal computer was a Radio Shack Color Computer and his first Linux exposure was with Slackware and several dozen floppy disks. He’s been using Linux Mint since version 8.
• Rob goes on to describe how he came to the mintCast.
• Our hosts and Rob then move on to various technology topics:
  • The current state of Linux Mint.
  • UEFI – Unified Extensible Firmware Interface.
  • Software patents.
  • Windows 8 and possible opportunities for Linux.

• A sticky, stormy night in Texas, just right for podcasting and Russ’ attempt to take over the MintCast.

Announcements:

• Pimpin’ the band: Thanks, as always, to Gamma Leonis for the theme music for the show.
• We recently learned of Tom, KB4HQA’s, unfortunate car accident after leaving the Dayton Hamvention this past May. We wish him a speedy recovery and return to podcasting.
• Richard is a fan of America’s Test Kitchen.

Topics:

• Pimpin’ the network: If you have a podcast and want to reach LHS listeners, please visit Black Sparrow Media and contact us to become a member! The Waveguides Podcast did and so can you.
• Who is your hero in amateur radio, living or dead? Let us know! Richard is gathering information for his super-secret project.
• Storm watchin and workin on radios. While a storm raged in Texas, Richard received an email about an IC-735 that would not power on reliably. Richard’s trouble-shooting philosophy: start with the things that are cheap to replace.
• Richard is hoping to pursue a high-speed multimedia (HSMM) and mesh radio project using DD-WRT or OpenWrt for use in emergency communications. Used routers, such as the Linksys WRT54GL, are ideal and can be found for little money.

Feedback:

• Leif, KC8RWR, wrote to clarify a comment to episode 86, explaining that he’d like to try using an NE602 frequency converter to an RTLSDR radio to receive ham bands.
• Brian, G3XGY, heard Russ on the Mintcast and is looking forward to listening to episodes of LHS! Welcome, Brian.
• Leif, KC8RWR, offers a suggestion for Grant, who was having difficulty with the LHS live Linux CD handed out at Dayton. He thinks it may have been due to Linux not recognizing Grant’s video card. Thanks, Leif.
• Harrison, VE2HKW, a sometime participant in MintCast, expresses his appreciation for episode 85, our interview with David Rowe and discussion of Codec2. Thanks, Harrison. Speaking of Codec2, Russ reports that David Rowe has won the 2012 ARRL Technical Innovation Award for his work on Codec2. Congratulations, David!
• Harrison, VE2HKW, wrote to ask for help with his Icom IC-735 (as mentioned above).

• Russ is anxiously waiting for delivery of two (okay, three) Raspberry Pi computers. Call the LHS voice line 909-547-7469, or send an email to info@lhspodcast.info, and tell Russ what to do with his Rasperry Pis. Wait, that doesn’t sound quite right, but you get the drift.

Feedback:

• Bruce, VE2GZI, writes to express his appreciation for the episode about GNU-Radio (Episode 84). It inspired him to try getting it to work under Linux Mint 11, but it’s been a struggle, and he asks for help. Russ managed to compile it on Linux Mint Debian Edition. Jlindsay in the chat room said he ignored the build script, and just did a cmake and make. Also make sure you have the proper version of portaudio installed. Bruce also tells us he’s waiting for his Hong Kong Dongle. ’nuff said.
• Scott, N9LJX, says he’s always had trouble with rig control, via Hamlib, and his FT-900, and wonders if that’s been improved. He’s happy to hear that yfktest works with Winkey USB. Russ looked at the Hamlib website about Yaesu radios, and saw the status listed as “.1 untested”, which indicates poor, if any, support for that radio. Richard suggests avoiding the USB or USB-to-serial adapter. Instead, buy an inexpensive serial port card for the computer and connect the radio to a real serial port.
• Someone in the chat room asked about a good personal cloud storage solution. Russ likes ownCloud. and has described it in episode 9 of his QSK Netcast.
• Jeremy, KB7QOA, sends a long email thanking us for the show, discussing his gradual move toward Linux, and wonders if he could have a version of the podcast without the music. Well, Jeremy, if you’re willing to subscribe to the show, you’ll soon have the option of a music-free feed.
• Grant, AA9LC, has embarked on a project to establish a Linux computer in his hamshack. He met Russ at the recent Dayton Hamvention, and has been trying to boot the LHS disc he received there, but it wants a username and password. He’s also tried Linux Mint 11 and is “mostly impressed.” As the disc contains nothing more than Linux Mint Debian Edition, Russ suggests the username may be one of “root”, “mint”, or “linuxmint”, and no password. However, it should boot directly into a “live” mode desktop without ever asking for a username or password. If that doesn’t help, Grant, let us know and provide a few more details about when you’re asked for the username and password. Russ and Richard also provide some hints about managing sound card audio.
• Look for Russ on Episode 124 of the Mintcast.

• Tonight’s episode is proof that LHS is at least as popular as the All-Star Game.

Topic:

• Interview with Bob Finch, W9YA, principal maintainer of yfktest.
• Bob got involved with the yfktest project because he was looking for a logging program like the old DOS program, WR9R.
• His ideal logger did not use graphics, did not require a mouse, and was very easy to learn. yfktest was close, but had a few problems, so Bob began submitting fixes and improvements.
• Over the past year, Bob began submitting code changes and eventually became the principle maintainer of the program, and has made over 150 patches in that time.
• Russ described his problem with the program for Field Day logging. Bob explains that the issue was due to the error checking, and had Russ not tried to enter the signal report into the Class field, it would have worked fine. Russ suggests having a line of text above the fields that provides hints as to what each field should contain. Bob added that to his To-Do list.
• yfktest is written in Perl, so no compilation is necessary to install.
• Bob is working on a version that is completely contained on a USB stick that would be operating system agnostic.
• Rudimentary networking features are in the code now, but disabled. So, it’s possible that networking might be a future enhancement.
• Get your copy of the latest version of yfktest by following the instructions in the README.NOW link at bfinch.net.
• Bob then describes another of his interests, rocketry, and is involved in the open source/open hardware rocketry project Altus Metrum.

Feedback:

• Rich, KD0BJT, of the Low SWR podcast writes to tell us of a Field Day logging program called fdlog. It’s written in Python and has networking capabilities for multiple stations. Rich also mentions the Java-based logging program JL. Thanks, Rich. fdlog is a graphical Field Day logging program written in Tcl/Tk, but hasn’t been updated in about a year.
• Leif, KC8RWR, sends us a link to a series of Youtube video tutorials for GNU Radio, the open source software project for RTL Software Defined Radios. He wonders if he could use an NE602 at the front end of the radio for HF, and use a Raspberry Pi to run GNU Radio. Our hosts discuss this and the Signetics NE602, a balanced mixer and oscillator on a chip.
• Dave, M0DCM, has been catching up on LHS episodes while convalescing. He describes his system for listening, and some experiences with the Ettus SDR, Funcube Dongle, and digital modes with his new Yaesu FT-817ND.
• David, KE0AZ, tells us that the power output of the Ettus transmitter daughterboards is anywhere from 50 to 200 mW.

It turns out that while simple, YFKTest is a competent and fully featured contest logger for many different contests. It works for CW and SSB logging, has rig control built in, and in the future may support network capable logging. There are many more features too numerous to name here. So sit back and let W9YA give you all the ins and outs. And stay tuned to the end of the show where our intrepid hosts tackle feedback from you, the listener. Best of luck in all your upcoming radio ventures.

73 de The LHS Guys

• No music this time; just one hour jam-packed with LHS goodness!

Announcements:

• Remember to sign up for the following LHS services:
  • The LHS SubReddit
  • The LHS Mailing List
  • The LHS Mobile app. Follow our updates via the mobile applications available for iPod, iPhone, iPad and Android devices.
  • Be an LHS Ambassador! Please join our Ambassador program. The event calendar has expanded quite a bit and we need your help. These events are now world-wide, so we could use some help outside the US as well as all over the country from California to Maine.
• YFKtest: Yes, there really does seem to be a problem. It’s been confirmed by John, EI7IG, that the program does not log contacts for the ARRL Field Day contest. Other contests work fine. Russ plans on emailing the developer, DJ1YFK, with these observations.
• From the “Yes, It’s an Antenna” File: Multi-band HF dipole made from horse fencing.
• Pulling a Lunduke: Holding Source Code Hostage. Our hosts discuss this blog post by Tom Nardi about Bryan Lunduke’s recent move to open source his software. Bryan is one of the hosts of The Linux Action Show.

Topics:

• Software Defined Radio (SDR)
  • A common topic Russ encountered at Dayton was about the available Linux options for software defined radios.
  • GNU Radio Project
    • Version 3.6.0 released in early May, 2012.
    • Version 3.2.2 is in the Debian Sid repository.
    • The latest version can be retrieved with git. (Install git with the command “apt-get install git”.) To download the software, issue the command “git clone git://gnuradio.org/gnuradio”.
    • Build instructions are available for most of the major Linux distributions.
  • SDR Hardware
    • Ettus USRP series works with the GNU Radio Project software. There are various models ranging in price from $700 to $2000, depending on the frequency range and options. Various modules allow receive and/or transmit on bands from 30kHz to 5.9GHz. Unfortunately, power output appears to be just 50-200mW, depending on the bands provided by the transmitter daughter board chosen.
    • Funcube Dongle costs £128 (~$200) and is a receiver only. The Funcube Dongle is a “radio receiver designed to allow anyone to try their hand at reception of satellites like FUNcube”. It covers 51.5MHz – 1.7GHz, less the region from 1.1GHz to 1.2GHz.
    • Perseus SDR costs $1000 and is also receive-only. It receives 10kHz to 40MHz.
    • SoftRock SDR is a kit available in various models from $20 to $90. Most are receive-only, but the Ensemble is a 1W HF transceiver. Some models are unavailable at the moment. The SoftRock RXTX Ensemble Transceiver Kit will allow you to build a 1W transceiver for one of the following bands or band groups: 160m, 80m/40m, 30m/20m/17m, or 15m/12m/10m.
    • RTL-SDR Devices range in price from $20 to $200 and are receive-only. More on the RTL-SDR project in an upcoming episode.

Feedback:

• Stewart, VA3PID, wrote to say that Russ was the first person, possibly ever, to correctly place his Scottish accent at Hamvention. He also remarked (in reference to a discussion in episode 71) that Chirp has come a long way; it can now program his Yaesu FT-857D!
• Jonas recently re-discovered LHS and expressed his appreciation for the show. Thanks, Jonas!
• Stefano, IZ3NVR/KD2BGM, asks for more help getting so2sdr built on his Linux machine. Russ suggests installing the compiler with “apt-get install g++ build-essential”, installing Qt and several other packages as described in Episode 83, then try building the so2sdr program again.
• Lastly, David Dominicki left a mostly unintelligible comment in response to Episode 78. Um, thanks… we think.

Music:

• None.

• Back from Dayton and ready to go.

Topics:

• Dayton Hamvention 2012
  • LHS had the same booth as last year at North Hall #131. Estimated attendance was 25,000 individuals. Russ recounts the experience. Thanks to Matt, KC8BEW, who stopped by and helped out at the booth. The LowSWR podcasters stopped by, too.
• FCC Dismisses Texas Ham’s Fourth Petition, Calls it “Repetitive”
  • Our hosts discuss.
• Contest logging for Linux.
  • Several people at Hamvention asked about contest logging software for Linux, but Russ was at a loss for a recommendation. Upon his return, he discovered…
  • SO2SDR Contest Logging Software
  • Stefano, IZ3NVR/KD2BGM was trying to get so2sdr to work under Linux Mint and while it would compile, it did not run, so Russ set about trying to get it going.
  • It’s not packaged for Debian or Fedora, so it must be built from source, available at the link above.
  • The program is written in Qt, so it can be run on devices which support that environment, including Linux and Windows. Of course, Qt must be installed in order to compile so2sdr.
  • Russ also had to install the following packages on his Linux Mint machine: portaudio19-dev (NOT libportaudio-dev; apparently, libportaudio-dev is too old), fftw3 and fftw3-dev
  • The compilation procedure consists of:

                  qmake
                  make
                  sudo make install

  • so2sdr compiled and ran fine. It did complain that it wanted a parallel port for switching between radios, but you can ignore that if you don’t need to do that.
  • Russ gives an overview of the features and capabilities.
  • There are a few drawbacks:
    • An apparent lack of SSB support? It seems to be CW-only.
    • Frequency input checking is broken.
    • Keystrokes are not intuitive, but are well-documented.
  • However, the built-in help file is quite useful.

Feedback:

• E-mail from Larry, KG4Q, extolling fldigi and JT65-HF. He wishes there was a version of JT65-HF for Linux. Well, Larry, there is! You can download the source here. Also, WSJT does JT65, too.
• Chris, K4FH, caught up with Russ at Hamvention and talked about his Linux in the Ham Shack presentation. He managed to put together a fine bunch of slides completely without our help. Sorry, Chris!

Music:

• “Down Today” by Jonathan Coulton from the album “Artificial Heart”.
• “Sucker Punch” by Jonathan Coulton from the album “Artificial Heart”.

One of the topics that kept repeating at Hamvention was: What is a good contest logger for Linux? Up until recently, it was hard to think of one. The ncurses-based application yfktest is out there, but thanks to IZ3NVR, our hosts discuss a new option. Tune in to find out what. There’s also some feedback, occasional rambling and hardcore lunacy. Everything you’ve come to expect from an episode of LHS.

73 de The LHS Guys

• Hacker Public Radio celebrates their 1000th episode!

Announcements:

• The Black Sparrow Media Mobile App for iPhone/iPad and Android has been updated. You can now listen to all of the old episodes, as well as new ones, via the app. wAVEgUIDES episodes are now included, as well. All streaming content is now available for iPad/iPhone. Please download and enjoy. It’s at the Google Play marketplace, as well as via the Black Sparrow Media website, and it’s still free!
• The LHS Hamvention fund drive was a success! LHS will be at Dayton Hamvention 2012, May 18-20, in the North Hall of the Hara Arena in booth 131, the same place as last year.
• Russ fixed a website bug that may have been causing some visitors to see the Black Sparrow Media site when surfing to LHS. Thanks to John, EI7IG, for pointing it out.
• Please sign up for the LHS mailing list at http://lists.blacksparrowmedia.net/mailman/listinfo.
• Please join the LHS subreddit and contribute show topic ideas, news of interest to our listeners, or just about anything else.
• Please tell your friends about the show.

Topics:

• Stan Horzepa, WA1LOU, in his recent Surfin’ column on the ARRL website, recommends open source Apache OpenOffice and the desktop publishing software Scribus. Note, LibreOffice is a fork of OpenOffice and is also quite functional. Both offer word processing, spreadsheets, database and presentations. Scribus may have a steep learning curve, but it’s a very powerful program. Easy tasks are easy to accomplish. Complex projects may take more effort to learn. Also note that many open source programs, like OpenOffice, Libre Office and Scribus, are available for Windows, OS X, as well as Linux.
• Take a look at the ham radio section at Linux Journal which also has links to their Ham Shack forum.
• Richard discovered several open source ham radio applications at Sourceforge: ircDDB_gateway, CQiNET, phppredict, contest loggers, fldigi, paclink-unix, OpenMOR, software for SDR radios, Ham Radio Net Logger, and more. So, don’t just look in your distributions repositories for applications. You may have to compile the programs from SourceForge yourself, but it may be worth the trouble.
• Finally, a reminder to visit KE2YK’s Random Oscillations website.
• An overview of ham radio apps for Android phones, available at the Android market, aka Google Play:
  • Morse Code apps:
    • Morse Decoder ($4.99)

• “L.E.O.” by Oleg Serkov from the album “Epoch Symbol,” courtesy of Jamendo.

On the Linux side, Richard found an article on the ARRL Web site which leads to a discussion of OpenOffice (Libre Office) and Scribus, two excellent document preparation suites. On the ham radio side, Russ discusses some useful Android applications which might be helpful to those operators who want to use their devices for logging, CW training, PSK31 digital mode communications and more.

Thank you for all the donations to the Hamvention fund. Russ hopes to see as many folks as possible during his time at the show. LHS will be in the North Hall, booth 131.

• Please sign up for the LHS mailing list.
• Please join our new Subreddit and contribute news stories, discussion topics, and any other items that may be of interest to our listeners.
• Scott, N8VSI, has tentatively agreed to be our ambassador at the Ohio Linux Fest in Columbus, Ohio in September, 2012.
• It looks like LHS will be at the Dayton Hamvention, May 18-20, 2012 in Dayton, OH. If you’d like to help make that happen, please donate!
• LHS is syndicated by the Kamiak Butte Amateur Radio Association, KB7ARA. The linked repeater sites cover almost all of Washington State, some of Oregon, and a bit of Canada as well. They are IRLP and Echolink connected.
• Ronny, K4RJJ, will be our ambassador at the Knoxville Hamfest on June 8th, 2012. Ronny calls in to discuss the upcoming Knoxville Hamfest, and his previous experiences as LHS ambassador.

Feedback:

• David, KE0AZ, writes to ask if LHS will be at Ham-Com, June 8-9, 2012, in Plano, TX.
• LinuxCanuck writes to defend Kubuntu against Richard’s recent tirades.

Topics:

• IRSSI Tips and Tricks
  • Irssi is a terminal based IRC client for UNIX systems. It also supports SILC and ICB protocols via plugins. Russ offers some tips on making Irssi a bit friendlier.
  • The functionality and ease of use of Irssi can be extended by installing and using third-party scripts. These scripts are written in Perl and available at scripts.irssi.org.
  • Once you download the script file, which we’ll call “dlfile” in the example below, you can install it and have it automatically run with Irssi by performing the following steps:

    # Create the scripts and autorun directories:
    linux> mkdir -p ~/.irssi/scripts/autorun   
    # Move the downloaded script file to the scripts directory:
    linux> mv  ~/.irssi/scripts
    # Change to the autorun directory:
    linux> cd ~/.irssi/scripts/autorun
    # Create a link to the downloaded script:
    linux> ln -s ../ . 

  • Some interesting scripts Russ is using:
    • nicklist-away.pl – provides a nick list and shows away status.
    • screen_away.pl – sets the away status when screen detaches.
    • nickcolor.pl – assigns a different color to each nick.
• Our hosts discuss the new release of Linux Mint Debian Edition (LMDE) with the MATE and Cinnamon desktops.

More Feedback:

• Stefano, IZ3NVR and KD2BGM, asks for help finding a good Linux contest logging program that supports SO2R (single operator, two radios) and CW keying. We don’t know of any, but perhaps one of our listeners can offer a suggestion.
• John, KD7AAT, offered a bit of criticism about the political content of episode 79 with Fab.
• Mike writes to extol the virtues of Linux Mint Debian Edition with the XFCE desktop, and hopes Richard will find it a suitable alternative to Linux Mint or Kubuntu. He also suggests Crunchbang Linux. Richard and Russ respond.

Donations:

• Don sent a nice donation for the Hamvention fund. Thanks, Don! We also received donations from Bob K., Charles H., Scott P., Craig B., and Harrison K. Thank you, everyone!

Music:

• “Gold and Steel” by Isaac Graham from the album Empty Vessels.
• “Charly” by Higgins from the album Zs.

In this episode, our trusty [sic] hosts talk with an Ambassdor. Richard’s interview with Ronny is so good it would make Anderson Cooper–well, throw up probably. They also discuss Linux topics like Mint-based distributions and irssi, an IRC chat client, as well as ham radio topics from HSMM to Winlink to contest loggers. The guys respond to a bunch of listener feedback and talk about some new features of the show.

A quick heads up: The interview audio is a little rough with some weird background anomaly. It won’t drive you mad, just make you wonder what was going on on Ronny’s side of the line. We suspect dinner and a seance.

• Tornado season has begun in Texas! Check out the videos at kcares.info

Announcements:

• The donations for the LHS to Dayton Hamvention fund have stalled. If you’d like to see LHS return to the Hamvention this year, please make a donation in the next week or two. All donations will go toward the cost of the booth in the vendor exhibition hall. If we fail to raise enough to attend, then the funds will go toward the expenses of producing LHS.

Topics:

• Richard’s Linux Adventures
  • Thank You Kubuntu, for once again obliterating Richard’s boot sectors.
  • Russ suggests using dd to perform what is essentially a low-level format of the drive. For example,

    dd bs=1m if=/dev/zero of=/dev/sda

    NOTE: This will totally erase your hard drive! Use caution!

  • Matthew, KC8BEW, in the chat room, suggests using Spinrite to repair a hard drive.
  • Richard declares that Debian is the Jesus Christ of Linux distributions, as it raised his hard drive from the dead, at least temporarily. It was the only distro he found that managed to install grub on the drive.
  • Richard also declares that Linux Mint sucks… at least for him. Audacity caused 100% CPU usage, spell check didn’t work, and it crashes.
  • Also discussed: CentOS, Scientific Linux, Fedora, PCLinuxOS, Xubuntu, lubuntu.
• Richard is writing an ebook on the National Traffic System.
• Russ again suggests Richard try Debian, but Richard says it won’t let him install Firefox. Maybe there’s a hardware issue? (Perhaps memtest might find a memory error? -Ed.)

Donations:

• We received several donations from visitors to the Dalton Hamfest and the KARC Hamfest. Thank you to our ambassador Ronny (K4RJJ) and to everyone who stopped by our booth at those events.
• Russ hoped to interview Roy, KK4ATD, our ambassador to the RARSfest last week. Apparently, the LHS booth was a great success.
• If you’d like to be an ambassador for LHS at an event, email us at ambassadors@lhspodcast.info and visit the Ambassadors link on the web site.

Feedback:

• Fab, co-host of Linux Outlaws, left a couple comments on the website expressing his gratitude for being on the show.
• Bob (W9YA) offers Russ some suggestions for entering the contact exchange information in YFKtest.
• LinuxCanuck left a comment saying he enjoyed the episode with Fab, asks for help getting the feed links on the web site to work, and offers some thoughts about Kubuntu.
• Roy, KK4ATD, the LHS ambassador to RARSFest, calls in to the show and describes the event. He’s also building a repository of ham radio packages for CentOS, called Hamux.

• An absolutely FABulous episode, in which we interview Fab Scherschel from the Linux Outlaws podcast. Fab’s de-facto father-in-law is DC5JM!

Announcements:

• Ronny, K4RJJ, attended the KARC Hamfest over the weekend as the LHS Ambassador. Details, photos and video will be on the web site very soon. Thanks, again, Ronny!
• Roy, KK4ATD, will be our ambassador at the RARSfest in Raleigh, NC on April 7th. Thanks, Roy!
• The LHS Web site now has a ‘Chat’ link which gives you the ability to join the #lhspodcast IRC channel without having a client, straight from the LHS web site.
• LHS hopes to attend the 2012 Dayton Hamvention. Please donate to the cause to help make that happen!
• A recent iOS update broke the Black Sparrow Media app for iPhones, but that will get fixed, soon. Look for new podcasts in the future. Visit blacksparrowmedia.net/join if you’d like to add your podcast to the Black Sparrow Media network.

Interview:

• Russ and Richard interview Fabian “Fab” Scherschel, co-host of the Linux Outlaws podcast.
• Fab transitioned from Windows to Ubuntu in 2007. The biggest issue was games, but he bought a PlayStation 3 to satisfy that requirement. Minecraft runs well on Linux.
• Fab’s primary motivation for Linux Outlaws was to practice his English.
• Our hosts then discuss Ubuntu, Linux Mint, Canonical and Debian.
• We then talk about software patents from a UK and German perspective.
• Fab is switching his servers from CentOS to Debian, primarily because there is no upgrade from one major release of CentOS to another. He also likes to try different distributions so as to maintain impartiality.
• Fab asks how Linux in the Ham Shack began.
• You can contact Fab via Google Plus.

Feedback:

• LinuxCanuck asks for help accessing links and RSS feeds from the website. Everything seems to be working on this end.
• Phil, AK4RQ, recommends the book ‘The C Programming Language’ by Kernighan and Ritchie, originally published by Prentice Hall in 1978. Thanks, Phil.

• “Faces Nameless” by Reform the Resistance from their album And It Begins… courtesy of Jamendo.

• Richard says life has been good, lately, except for Linux Mint, but we’ll get into that in a moment. Announcements and feedback are at the end of the show.

Topics:

• Linux Mint Sux!!! (At least, for Richard.)
  • Richard’s never-ending quest for a Linux distro that works for him. In the past few days, he’s tried various Debian-based distributions:
    • Linux Mint 12, with Gnome 3, MATE, and Cinnamon, but he didn’t like any of them. Too few configuration options for the desktop and gtkpod didn’t work, and that was a deal-breaker.
    • Linux Mint Debian Edition (LMDE): one of the CPU cores wasn’t running; fixed that, installed software and updates, but gtkpod didn’t work there, either.
    • Crunchbang Linux: too minimalist and too much configuration.
    • XFCE on LMDE was close. Richard replaced the Thunar file manager with Nautilus.
    • Xubuntu which is Ubuntu with XFCE. It looked good, was configurable, but lacked a few features.
    • Kubuntu, which is Ubuntu with KDE. He tried installing it from the live CD, which took 25 minutes to complete. After the reboot, it generated all sorts of hard drive errors. While it’s possible that the hard drive did fail, but Richard blames Kubuntu for causing the problem.
• Russ discusses OpenMediaVault, an open network attached storage solution.
  • It’s an alternative to FreeNAS.
  • Debian-based with a simple install process, while FreeNAS is based on FreeBSD.
  • Supports many features of FreeNAS, including CIFS/Samba, NFS, FTP, SSH, BitTorrent (via plugin), TFTP, and DAAP (via plugin).
  • Russ tried it in a virtual machine, and it installed easily. Once installed, all configuration occurs through the web browser.
  • While it’s perhaps not as mature as FreeNAS, it’s also a newer project, so it’s likely to improve. At the moment, Russ prefers FreeNAS, especially v0.7, but OpenMediaVault may very well catch up and surpass FreeNAS.
• Linux Contesting Software revisited. We covered a few in Episode 70, and here are a couple more.
  • Bill, W9YA, one of the maintainers of YFKtest, contacted Richard to inform him that YFKtest has had a major facelift, as well as adding a few features and fixing some bugs. It’s available as v 0.0.10 from the subversion repository. Russ downloaded the compiled version. He picked a contest, filename for the log, entered his call sign, mode, and some other information, but he had trouble entering a contact.
  • Minos Contest Logging Software is a contest logging suite for VHF and UHF Amateur Radio Contests. The current version is 1.5.4, and is available as a download or via the Subversion repository. It’s a Windows application, and there are directions on the Web site for running the application using WINE. If only they’d simply re-release with Linux-native code. Russ tried it and it does run quite well under WINE. It’s an open source project under the BSD license.
• Allstar Link Node Update: Russ now has an Allstar Link node number assigned, 28357. Allstar Link offers several packages: Limey Linux, ACID CentOS or Pickle Linux (for the BeagleBoard). Russ has been trying to get the ACiD version running on his LMDE machine so he can use it with his existing Asterisk installation. Meanwhile, Russ has his Echolink station working, node 54711.

Feedback:

• We received a voice comment from Ed, KB4VWA, who’s having trouble with some MFJ TNCs he recently bought at the Dalton, GA hamfest. Richard responds, though he’s had the least experience with MFJ TNCs. There are several possibilities: wrong on-air baud rate, bad connection, wrong dip switch settings, or poor or filtered audio into the TNC. Try using the jack on the back of the radio for the audio. Maybe the radio is not exactly on frequency?

Announcements:

• The OGG and MP3 feeds for the LHS Music and LHS Up All Night audio streams from the LHS web site have new links, so check your settings. The live streaming feed is mp3, so it works everywhere.
• The wAVEgUIDES podcast joins the Black Sparrow Media network! Visit blacksparrowmedia.net/join/ if you’d like to add your podcast to the Black Sparrow Media network.
• Episode renumbering: Ever since naming episodes 18a and 19a, it’s been bugging Russ, so they were renumbered to eliminate the letter suffixes.
• LHS hopes to attend the 2012 Dayton Hamvention in May. Please donate to the cause to help make that happen!

Then there’s some discussion of svxlink, an Echolink client and server application for native Linux environments, Allstar Link, Open Media Vault, contest loggers and a whole bunch of other stuff besides. Ahh, perhaps there is some content here after all. Hope everyone enjoys this episode and can perhaps contribute a dollar or two towards the Hamvention fund. It’s coming up soon and we hope to see you all there.

• We’re recording live, with music played as we record. Our guest tonight is Harrison, VE2HKW, from the MintCast podcast.

Announcements:

• The Dalton Hamfest will be in Dalton, Georgia on February 25, 2012. The LHS Ambassador is Ronny, K4RJJ. This has probably come and gone by the time you hear this.
• The KARC Hamfest will be held in Marietta, Georgia, March 17, 2012. Our LHS Ambassador is again Ronny, K4RJJ. Thanks, Ronny!
• The Northeast Linux Fest will be in Worcester, Massachusetts on March 17, 2012. We’re still looking for an LHS ambassador for this event. Contact us at ambassadors@lhspodcast.info if you’d like to help.
• Some of you may have noticed that the LHS web site has been down occasionally. For some reason, the server locks up. We can’t tell if it’s a denial of service attack, or an improper configuration, but we’re working on it.
• Paul, KE5WMA, in the chat room, reminds us of the Acadiana Hamfest on March 9, 2012, near Lafayette, LA., and the New Orleans Hamfest on March 24, 2012.
• Happy Mardi Gras!

Topics:

• Linux Utilities – Russ introduces us to some GNU/Linux utilities that provide information about your Linux system’s performance.
  • top shows a list of the processes running in descending order of resource consumption.
  • iftop allows you to monitor connections to your machine and the bandwidth used by each.
  • ifstat reports the amount of data passing through the interfaces every second, or other interval. For example, ifstat -i eth0 10 1 would report how much data moved through the first ethernet port in 10 seconds, and only do this once. Handy for capturing such information in a script program.
  • iotop shows what processes are the top disk I/O users.
  • All of these are command line utilities. Press Q to exit. Check the man pages for other keystrokes that can be used while the utilities run.
• Interview with Harrison, VE2HKW
  • Harrison, VE2HKW, is a recent ham radio licensee and describes his introduction to the hobby, what he likes and doesn’t like, and provides an overview of the Canadian amateur radio licensing structure.
  • Harrison is also a member of the Covey Hill Amateur Radio Club (CHARC).
  • Check out Harrison’s blog and pictures of his ham shack.
  • Tune in to the MintCast podcast on Monday nights, 8:00pm eastern time, 01:00 UTC. Join the chat at irc.spotchat.org, #mintcast
  • You can contact Harrison by email at harrison@mintcast.org or ve2hkw@gmail.com.

Feedback:

• We received donations from Steve S., Paul G., and Bill H. Thank you! These donations will be added to the Dayton Hamvention fund to cover the costs of LHS’ presence at the 2012 Dayton Hamvention in Dayton, OH, May 18-20, 2012.
• LHS had several mentions on Twitter by Neptune78.
• Serge, ON4AA, asks about using the LHS logo to publicize the show. Russ explains that the LHS logo is not Creative Commons licensed, so please ask for permission to use it.
• Larry Bushey of the Going Linux podcast responds to recent comments we made about their show. It’s a love fest!
• Leif, KC8RWR, continues an ongoing comment dialog.

• LHS merchandise is available at the Merch link on Web site. Check out the Badgerwear or buy one of the other LHS-branded items at PrintFection.com/lhs or Cafe Press. Thanks!
• Thanks to Dave from Gamma Leonis for the theme music.

Music:

• “Rainbow Over The Bayou” by Regis V. Gronoff, from the album Hummingbird & Honeybee, courtesy of Jamendo
• “Twist and Shout” by Swamp Daddy, from the album Swamp Daddy, also courtesy of Jamendo.

In the first segment, our hosts discuss three very useful Linux utilities for analyzing system performance on your desktop or server: iftop, ifstat and iotop. Get in-depth knowledge of how to use these tools in order to make your machine run better with fewer bottlenecks. And since Harrison is from a whole other country, it was decided he should tell all of us about amateur radio from a Canadian perspective, including licensing, regulations and operating practices.

Hamvention 2012 is coming up very soon. Please donate to the fund if you can. We hope to see everyone there!

73 de The LHS Guys (and Harrison, too)

• Only 317 days until the end of the world as we know it!

Announcements:

• The Black Sparrow Media application for iPad, iPhone and iPod has been submitted to the iTunes store. It is just awaiting validation from Apple, which may take up to two weeks. We’ll let everyone know when it’s available.
• Special Event Station W0S (Whiskey Zero Sierra) will be operating from the Titanic Branson Museum from April 13-15, 2012, commemorating the 100th anniversary of the Titanic disaster. Russ, K5TUX, will be operating the station at some point.

Feedback:

• Scott, AD7MI, asks for help linking APRS and his his Davis Vantage Pro2 weather station with Xastir. Our hosts suggest trying one or both of these:
  • Meteo – Davis weather station platform software for Linux. You can subscribe to the Meteo mailing list by sending a subscription request to meteo-request@lists.othello.ch. It has been several years since Meteo was updated, and is still not at version 1.0. You must download the .tar file from the web site as it does not appear in the distribution repositories.
  • wview- Cross-platform weather station software. It does need an internet connection if you are going to contribute information to various weather sites, such as:
    • Citizen Weather Observer Program (CWOP)
    • Weather Underground
    • Weather For You
    • awekas

    This program is under active development. Even if it requires a work-around to perform as you wish, it may be worth the trouble. If you’ve ever configured a Linksys router, the web interface of wview looks a lot like that. wview has a support site via Google Groups at http://groups.google.com/group/wview.

  Let us know how you get on, Scott!

• Paul, M0PGX, replied to our recent discussion of D-STAR and suggests trying the AllStar Link Network. Like EchoLink, it allows you to talk to other ham radio operators using just your computer and a microphone, including those operators running D-STAR.

  Russ signed up for the AllStarLink network; it’s very similar to joining EchoLink. AllStar uses the Asterisk VOIP system, and Jim, WB6NIL, is the author of the repeater link software. Russ had success using a Mac computer, but not with a Linux machine.

  Richard sees the biggest problem with EchoLink is that it only allows one connection per IP address, so you can’t have both a server and client at home. The EchoLink site only sees your IP address assigned by your ISP, which limits you to one connect from home. In this respect, AllStarLink appears to better in that it seems to allow multiple connections.

  AllStarLink is available in several combinations of Linux and Asterisk:

  • ACID – based on CentOS
  • Limey Linux – based on embedded Linux and bootable from a flash drive, and runs ONLY on several specific Mini-ITX motherboards.
  • Pickle – a specialized embedded Linux distro designed to operate on a BeagleBoard-xM (and DMK Engineering LOX board).

  Russ then provides an overview of setting up an AllStar Link client.

• Back to Paul’s email, he suggests we use the term “digital mode” when we should say “protocol”, which brings us to…
• Leif, KC8RWR, responded to Paul’s comment that D-STAR specifies a protocol, modulation mode, voice codec, etc. The modulation mode used is GMSK.

  Richard defends the use of “mode” as appropriate as the definition allows it to mean “a method or means of doing something”. For example, CW vs DFCW (dual-frequency CW), where DFCW uses frequency shifts to distinguish dots and dashes, rather than two different lengths of the same frequency, and spaces. Both are CW.

• Leif, KC8RWR, also comments on the possibility that he’s been nitpicking, as well as the use of Q-signals in voice conversations.
• Bill, KE5WMA, suggests that hobos migrate to New Orleans from Dallas this time of year because Dallas doesn’t have Mardi Gras!
• We received a donation from Bill H. Thanks, Big Poppa!

73 de Russ, Linux in the Ham Shack

• We’re a little light on content, but we’ll make up for it with enthusiasm!

Announcements:

• Ronny, K4RJJ, will be the LHS ambassador at the Dalton Hamfest, February 25, 2012, in Dalton, GA. Stop by and say hello.

Topics:

• Linux Mint 12 Review
  • Richard has been using Ubuntu for some time, but he’s been unhappy with the latest version. He’s rediscovered Linux Mint! Version 12 is out, with Gnome 3, Gnome 2, MATE, and Cinnamon, and he gives a brief review.
  • His primary needs: browser, email, Audacity, XChat, and a few others.
  • Using the Gnome 3 desktop, as a desktop fills with icons, a new desktop is automatically created.
  • By moving the mouse to a hot corner, you’ll see a high-level view of all your open applications.
  • Russ has been using Linux Mint Debian Edition, so he’s missing out on the Gnome 3 goodies, at least for now.
  • Our hosts then drift into a discussion of various desktop managers and visual effects.
• WINE: Wine Is Not an Emulator
  • WINE is a collection of libraries for Linux that support Windows library calls from a Windows application.
  • EchoLink, for example, is a Windows application works quite well under WINE on Linux.
  • If you can’t find a native Linux application that does what you want, you may find that WINE will allow you to run the Windows program.
  • There are a couple of different versions of WINE, all based on the core version of WINE.
  • Cedega: a version of WINE that supports a variety of Windows games.
  • CrossOver: a version of WINE that originally focused on supporting business applications such as Internet Explorer and MS Office, but has also expanded to include some games and running Windows applications on a Mac.
  • Richard browses the list of ham radio applications in the WINE application database.
  • Russ talks about installation and configuration:
    • Red Hat/Fedora: yum install wine
    • Debian-based: apt-get install wine
    • Some repositories may not have the most recent version of WINE (1.4 at the time of recording).
    • Under System Tools (in Linux Mint, or Debian) there is a WINE Configuration tool.
    • To install a Windows program under WINE, download the Windows installer application. At the command line, type “wine [name of installer executable]“, and the setup program should proceed just as with Windows. A program icon should appear under the WINE program folder, and the program will, hopefully, run just like in Windows.
    • Some Windows programs will run just fine under WINE; others won’t. Give your favorite a try and see!
  • One of the most-wanted ham radio applications, Ham Radio Deluxe v. 5.0, does not run at all under WINE. If you can find a copy of HRD v. 4, it should work under WINE. Remember, too, the native Linux application fldigi does much of what HRD would do.
  • Russ has also tried the N1MM Logger under WINE, and it worked fine.
  • The Winetricks tool might help get a Windows application running under WINE.
  • The WineHQ forum is a good resource for help.

Feedback:

• We had a donation from William A. Thank you!
• Leif, KC8RWR, continues a comment dialog about the origin of CUPS in Episode 67.
• G8FXM, mentioned LHS in his blog. Thanks, David.
• The Hoosier Hills Ham Club linked to the LHS site and we linked back. Thanks to W.W., KB9TMP.

Contact Info:

• Contact Richard at kb5jbv@gmail.com, Russ at k5tux@lhspodcast.info, or both at the same time at info@lhspodcast.info.
• Listen to the live stream every other Tuesday at 8:00pm Central time. Check the LHS web site for dates.
• Leave us a voice mail at 1-909-LHS-SHOW (1-909-547-7469), or record an introduction to the podcast.

Music:

• To be added.

After that, we had a request to discuss WINE in a little more depth than perhaps we had touched on in previous episodes. So we take a fairly broad view of the WINE project, how to use it for your applications, what its can and can’t do, and how it can benefit you.

As a quick reminder, Hamvention in Dayton is coming up quickly, from May 18-20. As always, if you can spare a few bucks, quid, euros, drachmas, or whatever currency you currently use to help send LHS out to Ohio for the weekend, we’d love to see everyone there. Any little bit will help.

Thank you to all of our listeners, as always. We couldn’t and wouldn’t do it without you!

73 de The LHS Guys

• They barely get the introductions done, and Richard is off on a tangent about the great hobo migration in Texas. All this just  proves Larry Bushey of the Going Linux podcast is right: LHS rambles. More on this in a moment.

Announcements:

• Richard and Russ discuss a disparaging comment Mitt Romney made six years ago about ham radio operators. He’s since reversed his position, at least publicly.
• Larry Bushey says LHS rambles in episode 160 of the Going Linux podcast. You know, Larry, you’re right.

Topics:

• Terminal emulation programs for Linux.
• If you’re interested in running packet radio with your Linux computer, you’ll likely need a terminal emulation program to communicate with your terminal node controller(TNC). There are several Linux tools you can use:
  • setserial is a command-line program designed to set and/or report the configuration information associated with a serial port.
  • microcom is a very basic terminal emulation program. Tip: pressing Control-\ will access the menu.
  • minicom is a menu-driven communications program. It emulates ANSI and VT102 terminals, has a dialing directory and auto zmodem download.
    • At the command line, type “minicom -s” to begin configuration. The first time you run “minicom -s”, you’ll probably want to run it as root so you have write access to the configuration file.
    • The first serial port in Linux is called ttyS0.
    • Most things will work at 9600 baud, 8 data bits, no parity bit, and 1 stop bit.
    • Text based modem control program.
    • Runs in a terminal screen
    • It’s useful for other serial port tasks, too.
    • Ctrl-A followed by W turns on line wrap, so you won’t have long lines truncated.
    • Install on a Debian-based system by using “apt-get install minicom” or use Synaptic.
    • Press Ctrl-A then X to exit.
  • GTK Term is a terminal emulator written with GTK+.
    • Gets added to the launch menu during installation, but with the name “Serial Port Terminal”, not “GTK Term”.
    • Has a nice looking interface.
    • Easy access to the serial port settings.
  • CuteCom is another graphical terminal emulator, with split input and output screens.

Feedback:

• Sean, AC0VD, writes about http://www.badgerbadgerbadger.com. Thanks, Sean. That’s pretty much where the whole badger thing on LHS began. Sean also likes the howto article Installing Linux on a Dead Badger.
• Ilan Rabinovich, of the Southern California Linux Expo, SCALE, sent a voice mail asking that we play promotions for the event. Unfortunately, we’re too late with releasing the LHS episodes to promote SCALE in time. We’ll try to do better next year.
• Richard has posted an article Making Yourself Clear on the Radio, and it received a couple of comments:
  • Tim liked the article and agrees that talking slower helps.
  • Lief, KC8RWR, notes that codes and ciphers are only prohibited when intended to hide the meaning of a transmission.
• We received a donation from Walter J. Thank you, Walter!
• John, KF6EFG, asks what was the open source podcast mentioned in a recent episode. We don’t remember, John, but it may have been any of these:
  • ICQ podcast
  • Tux Radar
  • Linux Outlaws
  • The Linux Link Tech Show (TLLTS)
  • Going Linux
  • Mintcast
  • To answer the second part of John’s question, neither Russ nor Richard will be at the Indiana LinuxFest. If you would like to be the LHS ambassador there, please let us know.
• The Dalton Hamfest in Dalton, Georgia, will have an LHS ambassador on duty! Look for the LHS booth on February 25th, 2012.
• If you’d like your podcast included in the Black Sparrow Media empire, send us an email!

Announcements:

• The free Black Sparrow Media Android app is available now. An iPhone app is in the works. Visit http://blacksparrowmedia.net/ or the Android Market to get your copy.
• Ronny, K4RJJ, has offered to be an LHS ambassador at the Dalton Hamfest, February 25, 2012, in Dalton, GA.
• The Southern California Linux Expo, SCaLE 10x will be (was!) January 20-22, 2012, in Los Angeles, CA. If you will attend and would like to be an ambassador for LHS, please let us know.
• Northeast Linux Fest will be March 17, 2012, in Worcester, MA. Again, if you’d like to be an LHS ambassador for that event, please contact us.

Topics:

• IPv6 – The End is Near (of IPv4)
  • Internet Protocol version 6.
  • If you can, start setting up your devices for IPv6 on your devices that support it. All of the current IPv4 address space has been allocated to the Regional Internet registrars (RIRs). IPv6 is the next version of Internet Protocol with a greatly expanded address space.
  • IPv6 is now the default IP stack for Linux. Unfortunately, many Internet service providers (ISPs) are not yet ready for IPv6.
  • There are IPv6 tunneling services that will forward your IPv6 traffic to IPv4 services:
    • SixXS
    • Freenet6
    • Hurricane Electric
  • If possible, give IPv6 a try. It’s inevitable, so if it works for you, you’ll be that much further along.
• HSMM – High Speed Multimedia, also known as “hinternet” (ham + internet)
  • The advantage is that we can use the normal “Internet” tools and off-the-shelf wifi hardware to provide emergency communications services.
  • One caveat: avoid using channel 1 as it uses the same frequency as AMSAT OSCAR 40 (Note: AO-40 became non-operational in 2004.)
  • Compared with other digital communications equipment, HSMM offers a lot of capability for little investment. The Linksys WRT54GL router is often used with alternate firmware from dd-wrt or OpenWrt.

• Happy New Year! Sorry for the delay in releasing the last several episodes.

Announcements:

• Would you be interested in the return of Resonant Frequency, the Amateur Radio Podcast, if it cost a dollar an episode? Send your thoughts to Richard via email at kb5jbv@gmail.com.
• Black Sparrow Media now provides an aggregate RSS feed of Linux in the Ham Shack, QSK Netcast, and Resonant Frequency. One feed, three shows! Quite a bargain.
• There is now a (free) Black Sparrow Media mobile app for the iPhone, iPad, iPod Touch and Android! See blacksparrowmedia.net for details, and send us your feedback.
• Andrew, AC8JO, has a blog that discusses Linux, amateur radio, and other topics. Naturally, he mentions our podcast. Thanks, Andrew!
• Leif, KC8RWR, responded to our comments in episode 67 that Apple created CUPS. According to Wikipedia, CUPS, the Common UNIX Printing System, was developed by a Michael Sweet beginning in 1997, and was later adopted by Apple for OS X. In 2007, Apple hired Michael Sweet and purchased his source code. The Apple website provides a somewhat different version.
  • Apple’s Version
  • Wikipedia Article

  Thanks for the information, Leif. Our advice is to pick the story you like and stick with it!

Topics:

• Channel Bonding for Linux
  • Channel bonding combines two or more network interfaces on a host computer for redundancy or greater bandwidth.
  • By bonding two or more Ethernet links to your computer, you get several benefits, including redundancy, so if one network port fails, the other still works, and greater bandwidth when both (or more) links are running.
  • Based on the Link Aggregation Control Protocol (LACP), though called different things depending on vendor, such as EtherChannel or PortChannel.
  • It’s relatively easy to set up. Briefly:
    • You’ll need an Ethernet port for each link, set up and configured in the normal manner. These ports will likely be called eth0, eth1, etc.
    • Install the ifenslave package, which allows you to create a “bond” interface, say bond0.
    • Create modules.conf file to alias the various ethx devices as bonding interfaces.
    • Modify your /etc/sysconfig or /etc/network/interfaces file (depending on your version of Linux) to include an entry that references the bond0 interface.
    • ifup the bond0 interface, and all the component interfaces should come up.
    • Other configuration settings will set up the failover time.
  • Resources:
    • http://www.linux-corner.info/bonding.html for Red Hat-based systems.
    • http://wiki.debian.org/Bonding for Debian-based systems.
    • Ethernet bonding on linux (Debian based)
    • Ethernet Bonding Configuration in Debian
    • Bonding
  • Our hosts then discuss the utility of load balancing between multiple network interfaces.
• More about the apt-cache utility
  • Russ provides more information about the apt-cache utility for Debian-based systems, previously discussed in Episode 69.
  • The basic syntax of the utility is apt-cache [command] [package(s)]. There are many commands you can use, including:
    • policy [package] shows which repository provided, or would provide, a specified package.
    • depends [package] shows all packages in the repositories that depend on the named package, and which other packages would be installed or suggested.
    • showpkg [package] shows reversed dependencies; that is, which packages depend on the named package, and the MD5 checksum of the package.
    • stats  shows some aggregate sums about all the packages in the repositories included on your system. For example, on Russ’ system:

          Total package names: 42814 (856 k)
          Total package structures: 42814 (2,398 k)
          Normal packages: 32874
          Pure virtual packages: 374
          Single virtual packages: 3670
          Mixed virtual packages: 465
          Missing: 5431
          Total distinct versions: 33706 (2,427 k)
          Total distinct descriptions: 33706 (809 k)
          Total dependencies: 200360 (5,610 k)
          Total ver/file relations: 35248 (846 k)
          Total Desc/File relations: 33706 (809 k)
          Total Provides mappings: 6402 (128 k)
          Total globbed strings: 197 (2,192 )
          Total dependency version space: 789 k
          Total slack space: 65.4 k
          Total space accounted for: 11.5 M

    • unmet shows packages in the repositories with unmet dependencies in the tree, that is, if you attempted to install, would fail.
    • show [package] shows meta information about the package. For example, “apt-cache show adduser” returns:

         Package: adduser
            Version: 3.113
            Installed-Size: 1100
            Maintainer: Debian Adduser Developers
            Architecture: all
            Replaces: manpages-it (<< 0.3.4-2), manpages-pl (= 5.6.0)
            Suggests: liblocale-gettext-perl, perl-modules
            Description: add and remove users and groups
            This package includes the 'adduser' and 'deluser' commands for creating
            and removing users.
            - 'adduser' creates new users and groups and adds existing users to
              existing groups;
            - 'deluser' removes users and groups and removes users from a given
              group.
            Adding users with 'adduser' is much easier than adding them manually.
            Adduser will choose appropriate UID and GID values, create a home
            directory, copy skeletal user configuration, and automate setting
            initial values for the user's password, real name and so on.
            Deluser can back up and remove users' home directories
            and mail spool or all the files they own on the system.
            A custom script can be executed after each of the commands.

  • Tim Allen’s character in his latest TV show, “Last Man Standing” is a Ham Radio Operator, KA0XTT.

Feedback:

• Kevin, KC9VAN, writes that he’s enjoying the show and just recently received his ham radio license. He also notes that he’s had the most luck with Hewlett-Packard printers under Linux. Thanks, Kevin. Russ has had good luck with Dell printers and generic PCL drivers.
• Leif, KC8RWR, posted several comments about episode 67. He suggests avoiding “all-in-one” printers, and instead, using separate printers and scanners. (I agree! -Ed.) Often, used scanners can be had for very little money. Leif also suggests buying printers with separate cartridges for each color. That way, you’re not throwing away all the colors when just one is empty. He seconds Russ’ suggestion to use a laser printer over inkjet, as the cost per page is less.
• Russ likes the Epson Artisan 835, especially for printing on CDs and DVDs, and it works well with Linux.

Richard discusses a wireless technology called HSMM or High-Speed Multimedia. This is a networking technique that blurs the line between FCC Part 15 and FCC Part 97, but gives ham radio operators some new and exciting things to try with their off the shelf wireless gear. HSMM has some nice features and will definitely earn you your Boy Scout Geek Cred Badge if you decide to dive in.

Thanks as always to our listeners, present and future. Comments and questions, make sure to send them our way. Donations are also appreciated. If you want to promote yourself, your ideas or your projects, leave us an intro to the show at 1-909-LHS-SHOW. Stay geeky!

Speak slowly and clearly

When we say speak slowly and clearly what we mean is sometimes at normal conversational speed  words run together when you are talking on the radio. Most radio equipment doesn’t reproduce all the audio frequencies of human speech or hearing. This can make it difficult to understand what someone is saying on the air. When you have some hearing loss it is even worse. I have some low end hearing loss so most of the time I have to add a speaker to my rig that produces more low frequencies to make the speech ineligible to me in noisy environments.

Annunciate. Some people don’t consider that when they speak they are trying to convey information. I know several people that just engage there mouth and let the words fall out without giving a second thought as to if the person on the other end of the conversation is having to decipher the noises emanating from their mouth. It is sometimes difficult to understand a conversation when you are in the same room with someone if the are slurring and mumbling their words. It is even more difficult when you are on a noisy frequency or using a narrow band width mode like SSB, or D*STAR. When you add the stress of a net situation people tend to speak faster than they normally would. They also tend not to speak clearly. This makes the problem even worse.

Use Standard ITU Phonetics

Another consideration is the use of phonetics. In most cases phonetics can greatly increase your ability to understand and be understood when conditions a frequency are not optimal. Ham radio operators are as a rule a playful bunch so we do things to make talking on the radio more fun like making up funny phonetics for our call sign. Unfortunately during emergency and disaster communications play time falls by the wayside and these home brew phonetics become more of a problem than an asset. Most of the time these home brew phonetics in no way resemble any of the standardized phonetic systems. When These operators find themselves in a situation where they need to be understood their home brew phonetics really don’t help. That is why the ITU Phonetic alphabet is the agreed upon standard for amateur radio emcomm communications. Every radio operator should be able to at least spell their call sign with these phonetics. Memorization of these phonetics is not difficult. Some operators can jump to phonetics without even thinking about it. Since so many letters in the English language like E,B,V,C and others sound so much alike it is very important to know the standard ITU phonetic alphabet.

Do not yell, Don’t whisper

Yelling at a microphone is a problem that has propagated down through the hobby. Many of us have come into the hobby by way of the citizens band service. Operating AM on cheaply made and badly maintained equipment in that service. Many others use sideband radios on a regular bases. On AM and Sideband speaking louder into the microphone can give you a small increase in the output power of your radio. Since we are using primarily FM radio equipment this is not the case. Without going off into an explanation of how FM works lets just say that yelling at your microphone causes distortion making it difficult to understand the information you are trying to convey. Since the equipment that we use on VHF and UHF is Frequency Modulated the Amplitude of your voice can cause more problems than you would think.

Whispering into the microphone also has problems. There are some operators out there that speak very quietly into there microphone. This results in a full quieting signal and barely understandable audio. Some times the microphone gain or deviation on your radio may not be adjusted properly. if you do not speak up while transmitting this can make the problem worse. In the case of a Net Control located in a noisy environment it makes your transmissions unusable. It also waste valuable time while the Net Control attempts to take your traffic. We don’t always have the luxury of calling a net from the comfort of our home.

Don’t eat the microphone.

Eating the microphone or holding it to close to your mouth is another bad habit that has trickled down through the hobby from the days of carbon microphones and the poor quality microphones of the past. Today the microphone supplied with a standard piece of amateur radio equipment is very good. Eating the microphone presents its own set of problems. Holding the microphone to close to your mouth can overdrive the diaphragm in the microphone and audio stage of the radio causing distortion which most often results in muffled audio. You may also experience Flat Topping of your audio signal that is very similar to clipping in other audio equipment. Over deviation of your signal is also a problem you may experience. Over deviation is a problem because most repeaters are equipped with a band pass filter to eliminate unwanted noise on nearby frequencies. This means that in some cases you could be sitting under the repeater running a hundred watts and not be able to key the machine because your signal exceeds the width of the passband. Another problem that may occur from eating the microphone is known as P-pops or Clicks. These are most common when the microphone is held directly in front of the mouth. These are not only annoying but can also make it difficult for net control to understand the information you are trying to convey. It is always best to hold the microphone off to one side of the mouth. I also like to use what I call the “Thumb Rule”. If I am holding the microphone to transmit I should be able to extend my thumb and lightly touch my chin or lower jaw. This seems to be just about the right distance and works well with most radios including hand held transceivers.

Lastly a word on hand held transceivers. Most HT’s come from the factory with the microphone gain turned up higher that mobile radios. So the built in microphones are “Hotter” than one might expect. They are designed to be held a foot to eighteen inches away from your mouth. Eating the microphone on these will cause many of the problems listed above to be much worse. External microphones will depend on the design of the microphone.

Q signals, codes and jargon

Since from time to time we will be transmitting information for use by non-hams such as our served agencies we need to keep Q-Signals, Codes, and Jargon to a minimum. Our served agencies have there own language or jargon and in most cases it doesn’t even remotely resemble the jargon that we use as amateur radio operators. The National Weather Service has its own language for describing weather and that is the only possible jargon that we may need to use. That information will be covered at Skywarn School where it will be covered by the folks that know what they are talking about.

Codes and Ciphers are prohibited by part 97 so they are not appropriate for any reason.

Q-Signals are a problem in amateur radio today because everybody wants to sound like a professional radio operator and they think that Q-Signals help achieve that goal. Q-Signals were designed to make cw operation easier and have no place on a phone (Voice) frequency especially during an emcomm net where the transmission and reception of clear and concise information is critical. Lastly, There is a place for Over, Out and Roger in emcomm communications. Most amateur radio operators tend not to use them correctly. My personal opinion is that if you want to acknowledge a transmission the word “Received” works just fine.

These are just a few of the things that can help all of us improve our communications skills. Clarity in communications is always important. It is even more important when we start to deal with Emergency and Disaster communications. Remember we are not transmitting for ourselves. We are transmitting for everybody.

• The Black Sparrow Media web site has been updated. If you use the aggregate feed from there, you’ll receive Linux in the Ham Shack, QSK Netcast, and Resonant Frequency (or Richard’s Radio Adventures) podcasts.

Topics:

• D-RATS
  • Bruce, VE2GZI, asks for help installing D-RATS on his Linux Mint computer. He tried adding the repository per the instructions on the D-RATS website, but received errors.
  • Richard has several suggestions: Make sure the whole line “deb http://d-rats.com/apt karmic release” gets entered into your sources.list file and that you are using the right repo for your distribution. Linux Mint normally falls a version behind Ubuntu. You might also try the tar file labeled “source” from the website, and use the archive manager to install it. Since D-RATS is written completely in Python, and Dan normally tries to stay with the most current version, check to see if you have the most recent version of Python installed. Finally, you could subscribe to the D-RATS mailing list from the website for more help.
  • Russ adds: If you wish to add the repository via the command line, there are a couple of ways to do it: (a) Edit the file /etc/apt/sources.list and add the “deb http://d-rats.com/apt karmic release” line, OR (b) Create a file in the /etc/apt/sources.list.d directory called, say, d-rats-repo.list, and add the “deb http://d-rats.com/apt karmic release” line to it. However, back in April, 2011, Steve Conklin, AI4QR, said his packaging of D-RATS had been accepted into both Debian Testing and Unstable branches. So, if you’re running Debian or Linux Mint Debian Edition, it’s already in the repository. Just issue the command “apt-get install d-rats”. For Ubuntu, there’s a PPA at https://launchpad.net/~sconklin/+archive/hampackages. That should work with Ubuntu 10.04 (Lucid Lynx), 10.10 (Maverick Meerkat), and 11.04 (Natty Narwhal). (It may not work with Ubuntu 11.10, Oneric Ocelot, but then again, it might).
  • Ed. Note: After this episode was recorded, the D-RATS website was updated to say:Ubuntu users should use the ubuntu-hams PPA in order to get packages for D-RATS. To install the PPA, go to a terminal and type:

    sudo apt-add-repository ppa:ubuntu-hams-updates/ppa
    sudo apt-get update
    sudo apt-get install d-rats

    The package manager will do the rest!

• Chirp
  • Chirp was written by Dan Smith, KK7DS, who is also the author of D-RATS.
  • From the Chirp wiki: CHIRP is a FREE cross-platform, cross-radio programming tool. It works on Windows and Linux (and Mac OSX, with a little work). It supports a growing list of radios across several manufacturers and allows transferring of memory contents between them.
  • Chirp currently supports 41 different model radios from Alinco, Yaesu, Kenwood, Icom, and others.
  • Richard tested it with his Icom IC-91 and IC-2200.
  • Chirp has a bare-bones interface, using a basic spreadsheet style, and is primarily for entering memory channel information. It will allow entry of call signs for D-STAR operation.
  • There are packages for Fedora and Ubuntu, and a source package for all other distributions of Linux. Chirp is written in Python, so be sure to have the latest version of Python installed.
  • There is also a self-extracting .exe file for Windows, and an app package for Mac OS-X. You must install the Python runtime package, available on the Chirp website, for the Mac version.
  • There is a Chirp mailing list, among others, at http://intrepid.danplanet.com/mailman/listinfo/.
  • Russ and Richard then discuss the cost of various D-STAR radios.
• Linux Tip: apt-cache policy
  • Russ offers a tip on how to determine which Debian repository is providing a given package.
  • Use the command apt-cache policy <package name>
  • For example: apt-cache policy libpulse0
  • The results of that command will show you which version is installed, if any, which version would be installed, and all other versions available.

• The 2nd Annual Northeast GNU/Linuxfest will be held March 17, 2012 in Worcester, MA.

Introduction:

• Welcome to another installment of Linux in the Ham Shack.
• After the holidays, consider attending a Skywarn training class so you’ll be prepared for the next storm season.

Topics:

• Contesting software for Linux
  • Ian, KM4IK, wrote that he’s now using Ubuntu 11.04 in his ham shack, but wants suggestions for a native Linux contest logging program. Good question, Ian, and we have a few suggestions. However, as neither Russ nor Richard are contesters, these may or may not be suitable for you.
  • JL Logger is a Java application that supports all of the major contests.
  • YFKlog and YFKtest are curses-based programs that run in a terminal session. YFKtest uses the hamlib libraries for rig control.
  • TLF also runs in a terminal session and uses hamlib for rig control.
  • KB is still in development. It runs in the Gnome window manager. Radio control for the Yaesu FT-1000 only.
  • Fldigi has a built-in logger, and will also work with CQRLog.
  • N1MM Logger has been reported to work under Wine. Others have had problems.
  • Russ tried installing N1MM under Wine, and while the installer ran fine, N1MM didn’t run properly when launched. Apparently, you must have the ALSA libraries installed. Note that the N1MM website warns that you should perform the Full Install, then install the latest update. Do not run the Full Install without first installing the update. Russ also tried the JL Logger, but it crashed. After realizing that it requires that the Java Development Kit, he installed that, but it still crashed. Look for an update in a future episode.
• VLC media player
  • Richard was having an issue with the VLC plugin for Firefox 7.0.1; the LHS music stream would play one song then stop. The VLC Media Player should work.
  • Our hosts briefly digress into a discussion of the DEFCON system; DEFCON 1 is the most serious, while 5 is the least. Hollywood often gets it wrong.

Feedback:

• Burt, K1OIK: please contact us about recent emails we’ve received from you. It may be that your email account may have been compromised.
• Leif, KC8RWR, wrote us regarding the discussion of EchoLink clients in episode 66. He tried QTEL and it worked fine. Thanks, Leif. (Also look at SvxLink.)
• Tom, KA2D, who is on the committee for Ham Radio University in New York, asks if there are any LHS Ambassadors in the Long Island, NY area. No, Tom, so you’re it!
• Andy, KC2ZWR, of the Suffolk County Radio Club, will also be at Ham Radio University on January 8, 2012, and offers his services as ambassador for that event.
• Tony, K7ISS, wrote to say he was happy that Richard had a good time at the Texoma Hamarama. Richard blogged about his visit to the event.
• Mike S., sent a VERY generous donation to the podcast. Thank you, Mike!
• The second annual Indiana Linuxfest will be April 13-15, 2012 at the Wyndham Indianapolis West Hotel. Russ is planning to be there, and so should you.

• Welcome back to another episode of LHS.

Topics:

• Texoma Hamarama
  Richard attended Texoma Hamarama at the Ardmore Convention Center in Ardmore, OK. He had a great time and describes his adventures. He took a few pictures and wrote a blog entry for the web site.
• HamQTH
  HamQTH is a callsign lookup service that is free and does not require a subscription. Russ gives his review. By registering, you can edit some of your information or use the search results in your logging program. Thanks to Ted, WA0EIR, for telling us about it.
• Adventures in Printing
  • Richard recently installed Linux Mint on his wife’s machine as she was becoming increasingly frustrated with the speed of Windows. He did run into an issue with getting her Lexmark all-in-one printer working, which leads him to a discussion of printing in Linux.
  • CUPS, Common Unix Printing System, originally developed by Apple for OS X, has become the standard printing system for Linux. You can administer CUPS by pointing your web browser to http://localhost:631
  • Most distributions install the Foomatic driver database. Another source of drivers is Gutenprint.
  • If your printer is not listed specifically, you may have success using a generic PCL5, PCL6 or Postscript driver.
  • Also check the Linux Foundation OpenPrinting project to see how well a given printer is supported in Linux. It’s a good idea to visit this site before you buy the printer.
  • Most network printers will be recognized and configured automatically by CUPS.

73 de K5TUX

Well let me see if I can come up with enough words to get all the pictures on this post.

Well October is here and along with the State Fair of Texas in Dallas it is also time for the Texhoma Hamarama in Ardmore Oklahoma. For many years a friend of mine and organizer of this event Henry Allen W5TYD has been trying to get me to make the track to Ardmore and check it out.

So I gathered myself up at 4:30 in the morning put a spark to the B.S.S. Improbable and made my way toward the Indian territories. I had really forgotten that the middle of the night was the only time that it is not a total pain to drive through Dallas. A little over two hours later I found myself in Ardmore. As described the hamfest was very easy to find. The shiny almost new convention center was right off I-35 at exit 33. I exited made a right turn then made another right turn and I was there ( I could never be a Nascar driver ).

The parking lot at the Ardmore Convention Center was more than ample and I was able to find a parking space very close to the front door. Not like Ham Com here locally where you have to park on the other side of town and ride a shuttle bus. Due to a mistake on the website I found myself there an hour before they opened the doors. So I spent some time talking to other Hams that had made the same mistake.

After paying a very resonable $8.00 to get in I roamed around looking at all the wonderful items to be had. At the end of the first row I went down I ran into Jimmy (Pinky) Pinston N5WYT from the Texas Baptist Men who was debating on buying some hardline for the freshly installed commercial repeater at the Baptist Mens building in Dallas. We talked about a few things like ARES in Van Zandt county where he lives and the fact that his license expired at midnight that night. Shame on you Pinky.

Went and sat in on the OK section ARES presentation. Then went and sat in on Andy WY5V’s amateur radio in the park presentation. Andy is king of amateur radio these days. King of ARES in Dallas. Big Chief at the VHF-FM society everything. Spent some time visiting with folks that I have known for years David Kaun N5DBK, Tim KD6FWD, and my little buddy Paul KD5TKO.

I really didn’t come home with anything except some good memories but we had a great time in Ardmore and I expect to go back many times in the future. Russ was not in attendance but you all know how he is.

73 everybody

• Who has a drawl?

Announcements:

• Richard has been reading about Ubuntu 11.10, “Oneiric Ocelot”, due to be released on October 13th. Our hosts hope to have some sort of review in the near future. Richard is also considering trying KDE. (The version of Ubuntu with KDE as default is Kubuntu.)
• Look for another episode of Richard’s Radio Adventures in the near future. It’s recorded mobile, and Richard wonders how to reduce the road noise with Audacity. Russ offers some advice on training the noise removal plug-in for Audacity.
• Richard did not make it to the Belton hamfest this year, but maybe next spring. He’s looking forward to attending the Texoma Hamarama, October 21 – 22, 2011 at the Ardmore Convention Center, 2401 North Rockford Road, Ardmore, OK.
• Richard is recruiting hams for the Kaufman County (TX) ARES group. Please visit the KCARES website for more information.
• Richard re-tells the infamous badger story. Speaking of badgers, you can find the Kiss My Badger tee-shirt, and a lot of other good stuff, at the LHS store.

Feedback:

• Danny inquires about an easy-to-use distribution for a senior and computer novice, perhaps Linux Mint. Our hosts suggest Linux Mint and PCLinuxOS. Note that the Mint live CD does not include the codecs, but the DVD does. If you install from the CD, you can install the codecs later.
• Danny also asks if there is a way to ask the Mumble developers to support screen-reading software. Since Mumble isn’t a GTK-based application, it’s probably not well supported under Orca. You may wish to raise your concerns on the Mumble forum, or on IRC at irc.freenode.net, #mumble, or click the Live Chat Now button on the www.mumble.com website.
• Burt, K1OIK, left a comment regarding Episode 61 entitled “South of the Border”: “I’d like to go south of your borders!” We’re a little worried about you, Burt.
• Michael, KD8GIJ, asks for instructions on removing a dual-boot installation of Linux Mint if he decides he doesn’t like it. You can, of course, just wipe the whole drive and reinstall Windows. You may be able to boot the Windows install media and let it “repair” your installation. However, you don’t really need to remove grub; just make Windows the default and remove Linux from the grub menu. If that’s not acceptable, you’ll likely have to wipe and reinstall Windows to return it to the pre-Linux state.Other suggestions include:
  • install Mint as a virtual machine with Virtual Box.
  • use the Windows Ubuntu Installer (wubi) which will also allow you to uninstall Linux after testing.
  • install Linux to a flash drive and boot and run from that to try it out
  • make an image of the Windows drive before installing Linux, perhaps with PartImage or Clonezilla, and you’ll have an easy means of returning to the pre-Linux-install state.
• John “The Nice Guy” Spriggs, G7VRI, asks about a live Linux distribution reviewed in Episode 62 that contained software to run EchoLink. (I think he’s referring to Andy’s Ham Radio Linux CD). svxlink is the Linux-native EchoLink client, but it is CLI-driven. The Windows client does run well under Wine. You may want to look at qtel, another Echolink client. It’s an older application. In fact, svxlink is based on Qtel.
• John also wonders if the music played on the show is Creative Commons licensed. While most of the music is Creative Commons or podsafe, the music in Episode 62 is not CC or podsafe, but Russ did have permission from the artists to play them.
• John pointed out that the description tags in the podcast audio files were empty. Thanks, John, and rest assured that Russ will be adding descriptions as time permits.
• By the way John, please contact Richard at the email address below as you may be able to help him with some music for another project.

Announcements:

• Texoma Hamarama 2011 will be October 21-22, 2011 at the Ardmore Convention Center, 2401 North Rockford Road, Ardmore, OK. Richard hopes to be there.
• If you attended the Huntsville, AL hamfest in August, let us know if you think it would be a good venue for LHS.
• Thanks, as always, to Gamma Leonis for the theme music.

Topics:

• Russ talks about the antenna feedline window passthrough panel he bought at Dayton. He’s also hoping to get a radio in his truck. Richard describes the window passthrough methods he’s used in the past, with foam pipe insulation or air conditioning insulation foam.
• Richard talks about the lack of ham radio activity in his area (Kaufman County, TX): no club, no RACES group, no ARES, etc. He called his ARRL SEC (Section Emergency Coordinator), Walt, KG5SOO, and learned that the local groups weren’t happy with the current ARES manager. The SEC says paperwork is being processed and the new emergency coordinator of Kaufman County, TX is Richard, KB5JBV! Currently, there are just two ARES members, Richard and the Emergency Manager, so if you’re in Kaufman County, TX, get in touch with Richard! (Congratulations, Richard!)
• There’s a new podcast out there: Richard’s Radio Adventures. Look for it on the Resonant Frequency feed.
• In Linux-related news, Russ lets us know that kernel.org was hacked a few weeks ago. Because the code was in an encrypted git repository, it was safe, but they moved it to github, anyway.
• Russ also says there was a brief period that GNU Emacs was packaged and distributed with a binary blob in it, which violates the GPL. It’s since been fixed.
• A security hole in SSL/TLS has been reported.
• Simon, HB9DRV, has sold the rights to his Ham Radio Deluxe software. Our hosts discuss the possible ramifications.
• Richard wanders into a discussion of Arch Linux. It seems there was an issue with Arch not being free (as in speech). However, Parabola GNU/Linux is Arch, but free of all the entanglements.
• If anyone out there is an Emergency Coordinator or Assistant Emergency Coordinator, send an email to Richard about how your EC is going. Richard is looking for advice on how to best set up the ARES EC organization in his county.
• Russ admits that his other podcast, QSK Netcast, has stalled, mostly due to a lack of his available time.
• Since some parts of the LHS website are now subscription only, Russ began researching SSL certificates. He found a couple of places that issue inexpensive or free browser-compatible certificates: CheapSSLs , under $10 per year, and StartSSL will issue personal certificates for free.
• Russ and Richard discuss their love for the Sansa Clips. Russ likes DoggCatcher for listening to podcasts on his Android phone.
• Richard talks about his secret antenna project. He’s now in an area with Codes, Covenents and Restrictions (CCRs) which preclude outside antennas. Years ago, he bought an Arrow dual-band J-pole antenna, and used it for packet and other stuff. Using some military surplus olive-drab fiberglass tent poles, he strapped the J-pole to the top of the tent poles and the poles to the top of an 8′ fence. He assures the neighbors that it’s just a flower pot hanger.

• Richard is still in the process of moving, but did get his WinLink rms gateway running as described in a previous episode.

Announcements:

• Jay Forrest has lauched The Linux News Podcast. The podcast will focus on topics such as software freedom, Linux development, Open Source software, Android and mobile devises, security issues, and Linux distribution releases. Our hosts offer their opinions.
• Ohio LinuxFest will be held in Columbus, Ohio on September 9-11, 2011. (Note: Russ will not be there, but maybe YOU can represent LHS. Visit the web site and look at the Ambassadors page to learn how.)
• Texoma Hamarama will be October 21-22, 2011 in Ardmore, OK. Richard might be there, so if you’re in the area, look for him!

Topics:

• Our hosts discuss the ARRL statement regarding HR 607, “Broadband for First Responders Act of 2011″. This bill provides for the re-allocation of the 420-440 MHz band, calling it part of the “Public Safety” spectrum. This is not the case, and we should contact our representatives and voice our opposition to this bill. The ARRL offers sample letters you can send to your representatives.
• Richard and Russ talk about various amateur radio programsfor Linux offered by Ted, WA0EIR.Russ built them all from the available source code on his Linux Mint Debian Edition 10 computer. In order to do so, he installed a number of development libraries:
  • libmotif-dev
  • libxmu-dev
  • libxpm-dev
  • libxbae-dev

  These are header files necessary for the compiler to properly build the programs.

• Each program requires the following commands to compile and install. Change to the directory containing the program and type:

    ./configure
    ./make
    ./make-install

  (You may wish to be root to perform the make-install command.)

• TWLOG – A basic QSO logging program. Useful for day-to-day logging, but not recommended for contest logs. It will export to ADIF. It requires the Xbae Matrix Widget.
• TWPSK – A simple bpsk/qpsk program. Co-written with Hansi, DL9RDZ
• TWCW – A Morse Code trainer that also allows keyboard CW operation.
• TWCLOCK – A world clock application that will also automatically send a CW identifier every 10 minutes.
• Check the /etc/X11/app-defaults directory for the “X resource” files to change the configuration options for these programs. For example, in that directory is a file called twclock that contains the callsign transmitted by TWClock.
• PSK31LX – A curses-based PSK31 program, so it runs in a terminal window or directly in a terminal session. For help, a man page is included. (Type “man psk31lx”.) It makes use of the arrow, control, and function keys. You can choose the audio and serial devices with command line parameters at start. Configuration parameters are stored in your home directory in the file .psk31lx.ini.

Feedback:

• Don, WS4E, asks for Internet resources for handicapped amateur radio operators. He’s familiar with the Handiham  organization, but wonders if there are others.There are many newsgroups and mailing lists dedicated to hams with disabilities. A Google search should return several. The Canadian National Amateur Radio Society site Amateur Radio for the Disabled, has several useful links. Richard mentions Lighthouse for the Blind. The ARRL has a page listing several articles. There’s also a Facebook group, Blind Amateur Radio Operators.
• Petr, OK2CQR, the author of CQRLOG, responds to Torsten’s (K5TOR) problems installing CQRLOG on a 64-bit machine: CQRLOG already has native 64-bit version. There is no need to install the 32-bit version. You can use the ppa at launchpad.net with packages for Lucid, Maverick, Natty and Oneirc. Version 1.2.1 will be part of the Oneiric release as well. More information is here.

• Welcome to another episode of Linux in the Ham Shack.
• Richard has moved to another QTH, and that’s provided some challenges.

Announcements:

• The LHS Ambassador Program needs your help. Russ explains what the LHS Ambassador program is all about and how you can get involved. If you’re interested, please contact us at ambassadors@lhspodcast.info
• Richard gives an update on the archiving of Resonant Frequency, The Amateur Radio Podcast.
• Richard complains about the Internet service at his new location, and Russ offers a tip about using wget -c for downloading large files.

Topics:

• Richard updates us on his AX25 project and moving to a new location.
• The Linux kernel goes 3.0: So what? Russ talks about the new Linux kernel, v. 3.0, recently released, and what you can expect.
• Your first license: What should you expect? Richard describes the process for getting your first amateur radio license. At one time, proficiency with Morse code was a requirement, but no longer. Richard used the Gordon West training materials to prepare. Having a local radio club or another ham can be a great help. There are two volunteer examiner groups: ARRL and W5YI. Both offer training materials for their examinations. When you go to a testing session, be sure to bring the required materials. After you pass the test, check the FCC website for your callsign. It often shows up just a few days after taking the test. Most importantly, after you get your callsign, get on the air!
• Revisiting OpenHatch (see episode 059). Russ discusses the OpenHatch project and how you can contribute to the open source community. There is a simple sign-up process to join OpenHatch. You can use OpenID or several other authentication services. OpenID can be used with several web applications. Once you join, you can specify the various skills you have, and the type of assistance you’d like to provide, such as development, bug fixing, documentation, etc. You can also start a new project or link your own project to OpenHatch. You’ll find development, testing and documentation opportunities.
• Russ gives an update on getting SvxLink to work. He had the build of version 11.05 blow up with an error about missing include files. He Googled the error message and found the answer. So he now has a working EchoLink server using SvxLink on 146.225 MHz. So, while it may be a bit challenging to build, it can work and provides a native Linux EchoLink program. (Thanks to Rick, K9AO, who sent an email that gave Russ the push to finish his SvxLink project.)

• Apologies for being late with this episode.

Announcements:

• LHS had planned on attending the Ohio LinuxFest on September 9-11 in Columbus,OH, and the Huntsville, AL hamfest Aug 21-22, but it’s just too expensive. To address that, LHS has started the LHS Ambassadors program where listeners of the show act as representatives for LHS at events. If you’re interested, please contact us at ambassadors@lhspodcast.info
• When you make a donation to LHS, you can choose to appear on the Sponsors page on the LHS website.
• Linux Format magazine, the producers of the Tux Radar podcast, recently reviewed various Linux-related podcasts, and LHS wasn’t even mentioned! Ouch!
• Richard announces the demise of Resonant Frequency: The Amateur Radio Podcast. Richard is looking for a place to post the articles and other content. The podcast episodes are saved at the Internet Archive, and the videos will remain on YouTube.

Topics:

• WinLink and AX.25
• Richard describes his trials and tribulations getting a WinLink packet gateway working under Ubuntu Linux.
• For the most part, Richard followed the instructions provided by Charles, K4GBB: How to install RMS Gate.
• Richard and Russ describe the steps in the Howto and possible pitfalls. Richard notes that you’ll probably want to run the commands as the root user, either by logging in as root or using sudo.
• (Note, near the end of Section 4 of the Howto, it appears the author left out the “wget” in the command to retrieve the script. On the page it reads:

  Get Script – Bernard has written a little Housekeeping script...

  http://f6bvp.free.fr/logiciels/ax25/rc.init.script && ...

• I think that command should be:

  wget http://f6bvp.free.fr/logiciels/ax25/rc.init.script && ...

  Note that I’ve shortened the lines with ellipses here. -Ed.)

• Ohio LinuxFest will be held September 9-11, 2011 at the Greater Columbus Convention Center in Columbus, OH.
• Linux in the Ham Shack promo from the Low SWR guys. Thanks!

Announcements:

• Our best wishes for a speedy recovery to MadamMoo!
• Our regular hosts are joined by Torsten, XE2/K5TOR.

Topics:

• Firefox 4 has been out a while, and version 5 beta is available at the time of recording. Our hosts discuss. The first thing Russ noted, was the increase in speed! Look for versions 6 and 7 before the end of the year. (As I write this, version 6 has been released. -Ed.)
• Kudos to The Linux Link Tech Show (TLLTS) and their interest in amateur radio. One of the hosts, Joel, aka “gorkon”, W3RAZ, has recorded a couple podcasts for Hacker Public Radio: Episode #738 is an introduction to amateur radio, and Episode #756 explains the basics of radio. Another TLLTS host, Allan, is N3MAW.
• Leo LaPorte of This Week in Tech has started a podcast about amateur radio. (It’s Ham Nation with Bob Heil, K9EID, and Gordon West, WB6NOA, under the TWiT banner and with Leo’s support and occasional participation. By the time you read this, Leo has his license and is now W6TWT. -Ed.)
• Russ describes the Linux from Scratch project that provides instructions for building your own custom Linux system, entirely from source code. Russ plans on providing more details of his experience with Linux from Scratch on a future episode of the QSK Netcast.
• Our hosts tried Ubuntu 11.04, Natty Narwhal, and discuss it, good and bad.
• Russ also tried Fedora 15, and liked the default desktop environment.
• Richard likes PCLinuxOS, and SUSE Linux.
• Linux Mint gets a mention, too.
• In future LHS episodes, look for information about svxlink, an EchoLink client for Linux, and codec2, an Open Source and patent-free audio codec.
• Torsten has had problems installing CQRLog on a 64-bit machine. Russ recommends installing the ia32-libs package to provide the needed 32-bit libraries. In Debian-based distributions, you can install that package with the command “apt-get install ia32-libs”. More information about running 32-bit programs on a 64-bit machine with Debian-based Linux is here.

• Introductions, chit chat, a bit about the Dayton Hamvention, Texas Linuxfest, and the Belton hamfest.
• LHS will be at several events this summer:
  • SouthEast LinuxFest (SELF), June 10-12 in Spartanburg, SC. (Yes, I know, by the time you hear this episode, it’s come and gone.)
  • Huntsville Hamfest August 20-21 in Huntsville, AL.
  • Ohio Linuxfest September 9-11 in Columbus, OH.
  • Stop by and say hello to Russ and Cheryl!
• Richard may be attending the Texoma Hamarama October 21-22 in Ardmore, OK.
• Russ tells us about the sewer failure at Dayton. Only two restrooms in Hara were working Saturday afternoon. Apparently it was fixed by Saturday evening.

Topic: PulseAudio

• Richard’s son is trying to start his own computer repair business and recently he received a call from Misha who wanted him to fix a sound issue on her Sony Vaio, which dual-boots Windows 7 and Ubuntu 11.04. Sound worked fine in Windows, but not in Ubuntu, and she preferred using Ubuntu. After working with the machine for a while, he figured out that PulseAudio was the problem, and replacing it with ALSA fixed it.
• While researching the problem, Richard discovered PulseAudio problems exist on more than just the Sony Vaio. He also found PulseAudio problems with Ubuntu, Fedora, Open Suse 11 or higher, Arch Linux, Zen, and Sabayon, and with both Gnome and KDE desktops.
• Two sites in particular were helpful:
  • [SOLVED] sony vaio sound problem
  • Fix Ubuntu Audio Problem in Sony Vaio
• Russ and Richard discuss Linux audio problems, and the current state of PulseAudio, particularly with WINE. Russ notes that he’s had no sound problems under Linux Mint.
• Russ describes various ways to troubleshoot PulseAudio issues on Linux.
• In Gnome, right-click on the speaker icon and select sound preferences. From here you can examine the hardware, choose a sound profile, configure your inputs and outputs, and see which applications are using PulseAudio.
• There are a variety of utilities useful for debugging PulseAudio problems:
  • paman (PulseAudio Manager Utility). Install it with the command “apt-get install paman”. It tells you a lot of information about PulseAudio, including “sinks” and “sources”. You can also use it to set volume levels with greater control than with the desktop audio manager.
  • paprefs (PulseAudio Preferences Panel) Install it with the command “apt-get install paprefs”. Allows you to perform advanced functions such as connecting PulseAudio servers together, send sound from one server to another, create virtual sound devices, etc.
  • pavucontrol (PulseAudio Volume Control) Install it with the command “apt-get install pavucontrol”. Allows you to see every application that accesses PulseAudio, set volume levels per channel, and other configuration settings.
  • pavumeter (PulseAudio VU Meter) Install it with the command “apt-get install pavumeter”. Creates a VU Meter window that displays your audio levels.
  • padsp, pamon Install with the command “apt-get install pulseaudio-utils”. pamon will allow you to capture the bytes of audio data. padsp allows you to pipe the audio from an application that does not normally support PulseAudio, into PulseAudio.
  • Remember, you can use the “man” command for help on any of these commands. For example, in a terminal type “man padsp” for help on the padsp utility.
• Check out Ted’s sound card programs for ham radio. They are all now PulseAudio compatible.

I (Russ) will admit to shirking my duties to some degree. Many things are going on in my life right now and I just didn’t want to deal with editing or recording of late. Richard has also had his share of life problems and we’ve both been out of pocket a few times between Episode #061 and now. I suspect our absence is coming to an end and regular production of LHS will soon resume.

Thanks to everyone for hanging in there with us. We now return you to your irregularly scheduled podcast.

• The 3rd annual Southeast Linuxfest is scheduled for June 10-12, 2011 in Spartanburg, SC.

Announcements:

• LHS will be at the Dayton Hamvention, May 20-22, 2011, booth 131 in the North Hall. Russ and Cheryl will be there. Stop and say hello.
• LHS will also be at the Southeast Linuxfest, June 10-12, 2011, in Spartanburg, SC. Russ will be giving a talk on Saturday, and Russ and Cheryl will be at the LHS booth.

Feedback

• Dan writes in about a Linux discussion he had at his radio club on March 8, and he mentioned LHS. Dan is also recording his own podcast, “Every Day Linux Use”. Good luck with that, Dan, and let us know where to find the podcast when it’s released.
• B.B., KC5PIY, writes about an article in the February 2011 issue of Linux Magazine discussing the OpenHatch project. B.B. shares his thoughts about how OpenHatch may apply to the podcast and amateur radio. Russ and Richard respond. Unfortunately, when this was recorded, the OpenHatch website was down. (From the OpenHatch website: “OpenHatch is an open source community aiming to help newcomers find their way into free software projects.”)
• Rick, K9AO, sent some detailed instructions for building SVXlink, an open source Echolink client, under Linux, and we’re including it in it’s entirety here. As you may recall from episode 56, Russ had problems with compiling the program.Hi Russ,
  I thought I’d send along the method that I have used to successfully build SVXlink under Mandriva 2010.2 and Ubuntu 10.10. I built the source on Ubuntu 10.10 late last year, so don’t have access to that machine at the moment. I built SVXlink from the latest SVN checkout on this Mandriva box, but this method also works fine for the release tarball.

  I don’t know if you generally use SVN projects, but I’m thinking that you likely do if you are as interested in helping to shape the development of actively developed projects.

  I create a directory called SVN in my home directory, and then do the SVN checkouts from there. Using the SVN checkout command below will create a subdirectory in the folder that you run it in, and then you can do the install from there. You likely are already familiar with this.

  Here are the specifics:

  ——————–
  Get the source:
  svn co https://svxlink.svn.sourceforge.net/svnroot/svxlink svxlink
  cd to the below directory:
  Build the source branch in /svxlink/trunk/src
  From there:
  make realclean
  make
  su to root
  make install
  ——————–

  If there are any missing deps, these will show up as the compile progresses. As you already know I am sure, you need the devel packages to match the deps to build from source.

  You will see errors, or what looks like errors as the build progresses after a realclean command. But if all of the needed libs and devels are there, the build process will create the necessary configs and then build the app. If you are concerned that the app might not have built correctly, doing another make will have the terminal scroll through the build process rapidly and then complete. If you get that far, do the root install. Then qtel from the terminal will bring up the client.

  There are a number of branches of the source code for SVXlink in development. I recommend the above main trunk first.

  There haven’t been any changes in the Qtel client for a while, so if all you are after is the client part of SVXlink there is no advantage to using cutting-edge SVN. There has been quite a bit of development going on in the server part, so experimenting with the SVN and joining the SVXlink devel list might be a good idea.

  Hope that helps, and keep up the good work.

  Rick, K9AO

Music:

• To be added.

• The 3rd annual Southeast Linuxfest is scheduled for June 10-12, 2011 in Spartanburg, SC.

Topic 1: JT65

• Richard enjoys the digital modes. Recently, he came across a signal he could not immediately identify, and found it was JT65.
• JT65 is one of the suite of programs in the WSJT package written by Joe, K1JT, and was originally developed for weak signal Earth-Moon-Earth (EME) contacts.
• It’s easier to install than WSPR (Weak Signal Propagation Reporter); simply download, extract, and go.
• Because the software is designed to achieve a weak signal contact, information is sent repeatedly. If everything is working well, a simple contact will take about 7 minutes.
• Like WSPR, stations transmit on a two-minute interval, so the computer clock must be accurate.
• One station will “transmit on the ones” meaning he is transmitting on the odd number minutes. Each transmission is usually about 50 seconds. Then, the other station sends on the even minutes.
• Typical contacts are callsign, signal report, and location.
• Signals sound a bit like weather fax, usually a bit above the PSK area on 20m.
• Richard was able to make 10 contacts in 15 minutes with 5 watts into his G5RV at 30 feet, on the 10m band, no less. He then made 5 contacts in 30 minutes on 15m, one of which was to South America.
• WSJT and WSPR are both developed by Joe, K1JT, a physicist and amateur radio operator.
• WSJT and WSPR can be found at http://www.physics.princeton.edu/pulsar/K1JT/index.html.
• One of the best websites Richard found for learning to use JT65 on HF is “The Complete Bozo’s Guide to HF JT65A by Andy, K3UK”. It hasn’t been updated in a while, but is still a good resource.
• The manual included with the program is very good, too.
• Richard recommends using the second set of messages provided in the program, rather than the default set, as the default does not include a signal report.
• Richard has prepared an “Intro to JT65″ video, available at the RF Podcast website.

Topic 2: Codec2

• Bruce, VE9QRP, back in January, suggested we talk about Codec2.
• From the Codec2 website:
  “Codec2 is an Open Source and patent-free audio codec, currently in alpha testing. It provides good voice rendition at 2550 bits per second, and we expect that its bandwidth will be reduced with continuing development. Its voice quality and latency are an improvement over Speex, when Speex is run at a similarly low bandwidth rate. The original motivation for its development was to provide a completely open codec to replace AMBE+, MELP, and other proprietary codecs for use in Amateur (“Ham”) Radio communications. However, the codec is potentially useful for commercial two-way radio, telephony, and other applications.”
• Russ plays some audio samples, and our hosts discuss how this might be used in ham radio applications.
• The resulting file is in a .wav container and thus can be played by any program that plays .wav files. While the result is adequate for voice, it’s not suitable for music.
• More links:
  • History of the project
  • More background and some how-to information from the author.
  • A PowerPoint presentation by the author.

Feedback:

• We received donations from Dan W., Matt M., Andrew H., and Paul G. Thank you!
• LHS will be at the Dayton Hamvention, in the North Hall, booth 131. We hope to see you there!
• Jim, N2ENN, linked to us on his blog site. Thanks, Jim.
• The Panhandle ARES group linked to LHS on their website. Thanks, guys.
• regexorcist of The Daemon and Penguin Oggcast linked to LHS. Thank you.
• Gary, KE2YK, has syndicated the LHS RSS feed on his eHamStore.net site. Thanks, Gary.
• Burt, K1OIK, thought the clip art of the foo dog (episode 55) looked like Russ.
• B.B., sent a long email, which we’ll discuss in an upcoming episode.
• Danny asked about the podcast that Gene has about Apple. That’s the Tech Night Owl Live program with Gene Steinberg.
• Dave, KI6ZHD, just found the LHS podcast website. Dave has written some documentation for various Linux topics and is a recent ham. His distro of choice is CentOS. He has been documenting his adventures at his blog and thought our listeners might be interested. He asked if we talked about TrustedQSL on Linux, and we did in episodes 43 and 46.
• Leif, KC8RWR, commented about dual-booting a computer with Windows if Linux has already been installed. He suggests using gparted to shrink the Linux partition, creating a Windows partition in the free space, and then installing Windows. Of course, it’s best to just use a spare computer or another hard drive. (We talked about all this in episode 56.)
• Richard points out that version 1.0 of CQRLog has been released.
• Jim, N2ENN, just installed straight Debianand offers a few hints:
  • Extra repositories: In the system/administration tab, there’s a package called software sources. Check them all and click close.
  • Flash vs gnash: don’t worry about gnash. Once the nonfree repositories are selected, open the Synaptic package manager and install flashplugin-nonfree, or from a terminal, type “apt-get install flashplugin-nonfree”.
  • Regarding codecs: all the codecs are already installed, or should be. If not, again in Synaptic, tick good, bad and ugly plugin modules, along with the base plugin.
• Russ received this from a radio club: Steve, N1NXU, wrote that he had a Tripp-Lite power supply that needed repair and he asked them for a schematic. They declined to provide one, so he recommends Astron power supplies, as schematics are included. These are available a most of the ham radio stores.
• John, KF6EFG, attended Indiana LinuxFest and asked Russ for a copy of his presentation from that event. Look for that information on the LHS website in the near future.

Announcements:

• Some listeners have requested a calendar of upcoming LHS events. So, if you have a calendar program that uses ICS calendar feeds, go to the LHS site and on the right side, look for the ‘Follow Us’ heading. Click at the third icon that looks like a calendar. Or, to see the information in your browser, click this https://zmx.bcef.info/service/user/info@bcef.info/LHS-Podcast.html.
• Again, LHS will be at the Dayton Hamvention on May 20-22. We’ll be giving away a computer, so drop by the booth and say hello. Please donate at the website to help defray the costs. Thanks.

In this episode, your fearless hosts tackle some of the hard questions concerning Open Source, namely: 1) Can anyone in free software agree on a set of standards for documentation and development in order to help newer users join the community, and 2) If it is possible, would anyone want to do it? When we’re all done philosophizing, send us your thoughts. We want to know what YOU think.

In this episode of our show, we catch up on almost all of our (very old) feedback and even manage to discuss a couple of items which may interest ham radio and Linux enthusiasts alike: JT65, a weak-signal digital mode, and codec2, a new audio codec designed for low bandwidth, telephone quality, error correction and to be free of patents or encumbrances of any kind. Enjoy.

• Apologies for the delays in releasing new episodes.
• This episode is an interview with Jonathan Nadeau of Frostbite Systems and a user of the Linux screen-reading program, Orca.

Interview:

• Orca is a screen reading program integrated with the Gnome desktop. It’s available for most Linux distributions.
• Russ and Jonathan discuss how a sight-impaired individual might install Linux. There are a couple of Linux distributions that have screen-reader support during the installation: Talking Arch Linux and Vinux.
• Speakup is another accessibility tool, but one that speaks the command line.
• Vinux is an Ubuntu-based Linux distribution with Orca built-in, allowing a sight-impaired individual to install it from the CD. Vinux is the distribtion Frostbite Systems normally installs for it’s sight-impaired customers.
• Slackware has a Speakup kernel, and more distributions are including the Speakup module as well. Several distributions can be installed using Speakup. Some instructions are available at the Speakup site.
• Russ mentioned the Quick Learning Techies Show (QLTS) that also occasionally discusses accessibility issues.
• Jonathan discusses the pros and cons of Vinux, as well as his concerns about it being Ubuntu-based.
• Richard asks Jonathan for more details about how Vinux talks a new user through the install.
• If the application is GTK-based, it will likely work with Orca; if it’s QT-based, it probably won’t work with Orca.
• Ted’s software (WA0EIR), including PSK31LX, works via ssh, so the programs are controllable from the command line and would work with the Speakup module.
• Meanwhile, Russ attempts to install Orca during the show.
• Jonathan mentions another podcast he does, This Week in Fedora, and says there is an amateur radio Fedora spin. (I could not find a link to a specific spin of Fedora for amateur radio, but there is a Special Interest Group. -Ed.)
• Frostbite Systems sells desktops and laptops with Linux pre-installed. Customers can choose from Debian, Fedora, Linux Mint, OpenSuse, Ubuntu and Vinux. A portion of each sale is donated back to the distribution chosen.
• Russ asks Jonathan about the hardware he uses in Frostbite systems. All of the laptops/notebooks have all-Intel hardware, while some desktops have nVidia video cards. All are completely Linux-compatible.
• Russ then examines the specifications of some of the Frostbite computers.
• Jonathan also produces several podcasts through Frostbite Media:
  • Frostcast: interviews with project leaders of various GNU/Linux and Free/Open Source projects.
  • This week in Fedora: interviews with people involved with the Fedora project.
  • This week in Debian: interviews with people within the Debian community.
  • Orcacast is on hiatus, but should resume in the not too distant future.

• Indiana LinuxFest promo, March 25-27, 2011.

Announcements:

• Jerry Taylor, KD0BIK, has announced that he will be recording new episodes of The Practical Amateur Radio Podcast. Welcome back, Jerry!
• The Mid-America GNU/Linux Networkers Conference (MAGNet Con) has been postponed until Spring of 2012.
• Check out the Resonant Frequency podcast.
• Linux in the Ham Shack will be at the Indiana LinuxFest, March 25-27, 2011 in Indianapolis. Stop by and say hello. LHS will also be at the SouthEast LinuxFest and the Ohio LinuxFest.

Feedback:

• Ilan Rabinovitch writes to tell us about the Southern California Linux Expo (SCALE 9X), February 25-27, 2011.
  Thanks, Ilan. Sorry we couldn’t include this earlier.
• Kevin, KB9RLW, writes in response to Episode 51 that he agrees that Linux is a good fit for the amateur radio community for several reasons: added flexibility, security, and more choices. Even Windows 7 is still vulnerable and he points to a recent Sophos test. He keeps a WindowsXP virtual machine, in VirtualBox for those Windows applications he must run, though WINE usually works fine. He’s also a fan of The GIMP, OpenOffice, Inkscape, and Scribus. Good points, Kevin, thanks.
• Dave, KA6YQ, points us to instructions for running the DX Lab suite in Linux, which, unfortunately, just says that you can run their software in a Windows XP virtual machine, which isn’t the same as running it on Linux.
• Rick, K9AO, tells us of a native Linux EchoLink client SvxLink. Russ uses the Windows EchoLink program under WINE, but checked out the program. He tried building it from source, because he’s running Debian instead of Fedora, using the posted instructions, without success, but he’ll keep trying.
• Joseph C. sent a donation to the LHS Dayton Hamvention fund. Thank you very much, Joseph!
• Jonathan Nadeau of Frostbite Systems says that if you want to install the extra codecs in Debian, you must first add the multimedia repository to your sources list file (/etc/apt/sources.list). Add the repo, then install the codecs you want. Linux Mint Debian does much of this by default.
  Richard spent most of a day trying to uninstall Gnash and install Flash… without success. And it’s true that IceWeasel and IceDove are the same as Firefox and Thunderbird, but they are one release back. Richard prefers running the current versions.
• Russ tells us that by adding the following line to your /etc/app/sources.list file

  deb http://www.debian-multimedia.org testing main non-free

  and then doing an apt-get update, you’ll be able to install the non-free codecs.

• Russ and Richard then talk about removing Gnash:

  dpkg --remove --force-all gnash

• Russ recommends GhostBSD if you’d like to play with BSD.
• John, EI7IG, writes that Episode 53 was a “cracker” and that he’s a fan of fldigi, too. He also tells us of APRSISCE32, an APRS client for Windows written by Lynn, KJ4ERJ. John has been running IPV6 in the shack and points us to this article by Geoff Huston. Thanks, John.
• Larry Bushey and Tom Chaudoir of the Going Linux podcast send their regards.
• Russ gives an impromptu review of the Linux Reality podcast by Chess Griffin.
• LHS is a sponsor of the upcoming Indiana LinuxFest, and Lord D. sent his appreciation.
• Mogens, OZ1AKN, asks for help on a couple of topics.Question: Is it possible to automatically start a program under WINE?
  Russ responds with:To make a program under WINE start at boot, look at /etc/rc.d/skeleton for a sample. Copy the skeleton file to the name of the WINE app you want to start, then edit it to start whatever you want to start, such as /usr/bin/wine/echolink.If you want a program to start when the X session starts, click:
  menu -> system -> preferences -> statup applications -> Add a startup app
  In the dialog, give it a name and add the command: /usr/bin/wine <application path>

  Question: How do you reinstall Windows in a dual-boot setup?

  Russ responds with:

  It’s easier to install Windows first, then Linux, as the Linux boot loader will automatically detect Windows and include it in the boot menu. If you install Linux first, then Windows, Windows will overwrite the Linux boot loader.

  Otherwise, if you’re trying to repair a dual-boot system, try booting with a system rescue CD to repair GRUB.

  Google “linux boot ntldr ” to find instructions to tell the Windows NTLDR to also boot Linux.

• Tom H. sent a donation to the Dayton Hamvention fund. Thanks, Tom!
• Frazer writes that the LHS Facebook fanpage seems to be geoblocked in Canada. (Russ has fixed the problem. Thanks, Frazer.)
• Jim, KG9EQ, discovered the podcast while searching for QSSTV and wrote to share his appreciation for the website. Thanks, Jim.
• B.B. in the chat room asked if Jerry Taylor has resumed the Practical Amateur Radio podcast. (Richard’s comments were recorded before Jerry resumed recording episodes.)
• Paul, KC9QYB, has resumed his Teen Radio Journey podcast.
• Brady and Rich recently released another episode of the Low SWR podcast.
• Finally, a note to the ICQ Podcast: We encourage Colin to talk more!

• Hacker Public Radio promo.

Announcements:

• Check out the Mid-America GNU/Linux Networkers Conference (MAGNet Con) website for the latest news and registration information. (Note: the event has been postponed until 2012.)
• Take a look at the LHS website for some new screencasts.

Topics:

• Richard and Russ talk about the origins of the LHS podcast name. See Linux on the Desktop podcast.
• Richard talks about how to build a Delta loop antenna, and using a piece of 75 ohm coax to act as a matching transformer between the antenna and the 50 ohm feed line. He also describes velocity factor for coaxial cable. Here’s an illustration of a 20m Delta loop similar to what Richard describes.
• Just for fun: Fab’s Crap Alert
• linSmith, in the Debian repositories, is a program for plotting Smith Charts, and more.
• Richard then talks about Henry Allen W5TYD, formerly K5BUG, of Texas BugCatcher antenna fame, and the inductors he wound around Plexiglas forms. (Henry ceased production of his antennas in 2009 and has retired. -Ed.)
• Russ uses an Alpha Delta DX-CC multiband dipole, in preference to a G5RV dipole.
• Other antennas mentioned:
  • Barker Williamson
  • Resonant dipole antennas
  • 135′ doublet (I use a 4:1 balun and an LDG autotuner. -Bill)
• Impedance of transmission lines: 50 ohms for communications coaxial cable, 75 ohms for cable TV coaxial cable, 300 ohms for the old TV twinlead, 450 ohms for window line, and typically 600 ohms for ladder line.
• Richard explains Standing Wave Ratio (SWR).
• Richard relates an Field Day story from several years ago… Commodore-64 running packet radio on the tailgate of a truck in 100-degree heat, and burning up the C-64.

Feedback:

• Audio feedback from Frasier K. thanking our hosts for the podcast. He’s currently studying for his ham license via HamTestOnline, and learned about Linux from the podcast. He’s now running Ubuntu 10.10 on his laptop and rockbox on his iPod. He’d like some sort of automatic calendar reminder service to alert him when a new episode will be recorded. Thanks, Frasier, and we’ll look into that.
• Mitch, KC2MBN, says that he enjoys the podcast. He’s now an Extra class licensee, but is new to Linux. He recently tried dual-booting Windows 7 with Pinguy OS and reports some troubles, and asks for some recommendations for a distro. Thanks, Mitch. If you have a spare machine, it would be better to run Linux on that rather than going to the trouble and risk of dual-booting. You might try actual Ubuntu, Debian or Linux Mint. Crunchbang Linux is also easy to install, as is PCLinuxOS.
