LHS Show Notes #069

Posted on by Russ Woodman

Introduction:

  • 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 https://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.

LHS Show Notes #068

Posted on by Russ Woodman

Introduction:

  • 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.

LHS Show Notes #066

Posted on by Russ Woodman

Introduction:

  • 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.

LHS Show Notes #065

Posted on by Russ Woodman

Introduction:

  • 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.)

Feedback:

  • We received a donation from Oscar, N6PAZ. Thank you! If you'd like to donate to the podcast, please click the Donate button on the website. Oscar also visited the LHS booth at Dayton, and left a comment on website expressing his appreciation for the LHS website.
  • F8ARR conducted a poll on his website asking what operating system his visitors used in their ham shacks. He found 23% were using Linux! He also linked back to the LHS site. Thanks!
  • David, N1EA, tells us that the new website for Vinux is vinuxproject.org. Vinux is a remastered version of Ubuntu, optimized for visually impaired users. It includes several ham radio applications, including TLF (The Left Foot), a console-mode logging and contest program.
  • AmiZed (KB2MOB) wrote a very nice review of LHS. Thank you for the kind words!

LHS Episode #066: His Name is Ted

Posted on by Russ Woodman

It's no mystery that we at Linux in the Ham Shack are big fans of the application known as fldigi. We've even had the author of the program, W1HKJ, on the program to talk about it. We consider it one of the best Linux-native programs for ham radio ever written. That being said, one of our longtime listeners has also written some small, efficient and easy to use ham radio programs for operating PSK, logging, learning and transmitting CW and more. His name is Ted, WA0EIR. We've mentioned Ted in the past, but this time we decided to take a real gander at his applications. There's plenty of Linux and ham radio goodness sandwiching the main segment as well so no one will go away disappointed. Thanks for listening, and keep fighting the good fight!
