Show Notes #088

Posted on by Russ Woodman

Introduction:

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

Announcements:

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).
  • Claudio of the LinuxBasement podcast thanks us for the mention in episode 87.

  • Watch the Events Schedule on the LHS website for more events!
  • Click the Amabassadors link on the website and volunteer to be an LHS Amabassador at a Linux or ham-related event.
  • 20th annual Gainesville Hamfest Gainesville, Texas, Saturday, August 25, 2012, Civic Center.
  • Joplin Hamfest, Joplin, Missouri, August 24-25, 2012, Holiday Inn Convention Center. Look for Russ and Cheryl!
  • 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.

Show Notes #086

Posted on by Russ Woodman

Introduction:

  • 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.
