• Steve posted a message at the Resonant Frequency forums and asked about the early episodes not being available on iTunes. That was a “feature”, but Richard “fixed” it. Going forward, once we hit 50 episodes, older ones will drop off the feed to iTunes, so you’ll need to go to the web site to get them.
• Chris, ZL2CCO, posted a link to the LHS site on his blog. Thanks, Chris!
• Via snail mail we received a donation and feedback from Tom, NC0O. He’s been enjoying the podcast and sent a donation to support the Dayton expedition. Thanks, Tom!
• Walter, KV6M, writes to clear up a mistake from Episode 31. We incorrectly attributed the penultimate donation to the Dayton fund to Walter, WN3LIF, but it was, in fact, from Walter, KV6M. Sorry, Walter, we’ve corrected the show notes, and thank you for the donation, and correction. We’re sorry for the confusion.
• Doug, N6LMX, sends his greetings and wonders what happened to a message he sent some time ago and was never mentioned, so he sent it again. (Richard had been holding it for the other show.) Doug wonders which Linux distribution Richard chose for his old Dell Latitude laptop. Richard chose Crunchbang Linux Lite. Also mentioned, the Midori browser.
• Larry, W0AY, writes to express his appreciation for Episode 31. He would like to see Richard get a mute switch for his microphone. Thanks, Larry, and we’re currently soliciting donations for a noise gate for Richard.
• LHS got a mention in an anonymous comment in the Linux Journal forums.
• Chris, K3DC, mentions LHS in a presentation he prepared, perhaps for a club meeting.
• Another LHS mention in an IRC log posted to pastebin.
• Jim, N2ENN, writes to offer some information about microphones in response to Bill’s microphone rant in Episode 31, and discusses Linux drivers. Thanks for the information, Jim. We’ll talk more about this in a later episode.
• Glynne, KD5VQD, offers his wallet-sized reference card for the phonetic alphabet. Thanks, Glynne. Russ will post it in the Articles section of the Linux in the Ham Shack web site.
• Klaatu mentions in his blog that he enjoyed the song “Flash in a Bottle” by Dead Heart Bloom in Episode 30.

Last week in the Linux in the HAM Shack chat room, we had a lot of participation from our listeners. It was so great to see everyone there. We hope that in the future, more people will get a chance to check out the live show. Check back here on the web site for the schedule of live recordings.

This episode of Linux in the Ham Shack is jam-packed with content. We have a special guest from around the Interwebs that you will likely know if you listen to other podcasts about Linux. The show did run a bit longer than usual, but there is just so much in it I couldn’t begin to tell you everything you’re going to hear. I do hope that you’ll stick around for the entire episode because there are some goodies near the end that you will not want to miss out on, including how you can win significant cold, hard cash.

Thanks to our special guest, our live participants and to everyone who listens to the show. PLEASE, tell everyone you know about us, and that we’re not just for amateur radio enthusiasts. Technofiles, geeks, Linux and FOSS addicts and just about everyone will gain something from the podcast. Oh, and due to a couple of technical problems, the audio quality in this episode is poor in a few places. I did the best I could. Next time it’ll be better. Have a great week!

Welcome back, Richard!

Contributors:

• Linux in the Ham Shack showed up on Podcast Sniper.
• Chris, ZL2CCO, mentions LHS on his blog. Thanks, Chris!
• Doug, N6LMX, is listening to Episode 31 and recommends the Griffin SmartTalk Headphone Adapter for the iPod Touch. It adds a microphone to your headphones. He bought his at Fry’s. (You can also find it at Amazon for a little less money. Click through our Amazon store and support the Black Sparrow Media podcast empire! -Ed.)

Announcements:

• Texas Linux Fest is Saturday, April 10, 2010 at the Monarch Events Center, Austin, Texas.
• Southeast Linux Fest is June 12-13, 2010 at the Marriott at Renaissance Park hotel in Spartanburg, South Carolina.
• We met our fund-raising goal for attending Dayton Hamvention 2010! The next goal is to raise enough money for a noise gate for Richard.
• Richard expresses his appreciation for everyone’s patience and support during the past few weeks.

Links and Notes:

• Amateur radio satellite operation.
• Doppler shift
• Footprint
• Linear transponder: a broadbanded repeater that operates over a range of frequencies.
• Satellite tracking: there are programs that will help you find when and where a satellite will appear over your location. This page lists several, including some that run on Linux.
• You will very likely need an antenna with gain, and probably a means of moving the antenna to match the trajectory of the satellite as it passes by.
• SAREX (Shuttle Amateur Radio Experiment) has been superceded by ARISS (Amateur Radio on the International Space Station).
• Equipment considerations. A VHF/UHF radio with sideband capability is often required, as is a cross-polarized antenna with gain.
• More info can be found at the AMSAT site including Keplerian Elements and other tracking tools.
• The ARRL publishes several books on satellite operation.

Music:

• “Long Way Home” by Kasey Anderson from the album “The Reckoning”
• “Amnesia” by Roots of Rebellion from the album “The Looking Glass”

Richard is back and everything is right with the world–except Russ. Plans are in the works for setting up at the Dayton Hamvention. Many thanks to all of our listeners who donated to the cause. Our next donation goal, is $150 to get a noise gate for Richard. We know at least a couple listeners who should be happy about this, and we suspect there may be a few others out there. Of course, we’re committed to improving the quality of the program whenever and wherever possible.

This episode is a little heavy on the radio side of things. However, don’t be deterred. Richard gives us a lot of great information about satellite technology, concepts such as Doppler shift, transponders, antenna polarization, the science of orbits and much more which will appeal to your inner geek whether you’re into ham radio, computers or just science and technology in general. Have a great week, and we look forward to seeing everyone in the chat for the next live recording on Tuesday, March 2nd.

All of us at Black Sparrow Media wish to express our sincere condolences to Richard on the passing of his mother. Our thoughts and prayers go out to Richard and his family. He won’t be joining us this time, so we’ll carry on with a round table episode.

Contributors:

• Ted WA0EIR, in snowy Iowa, Andy aka Integgroll on IRC, and Bill KA9WKA join us for a round table discussion.
• Jay writes in about the Linux Journal episode (#029) and the analysis of the Amazon Kindle and DRM issues. Our panel talks about the Kindle , e-readers in general, and DRM issues. Russ mentions how Amazon retracted a couple of George Orwell titles.
• Google alert tells us that Linux in the Ham Shack and other amateur radio podcasts are being played over a local repeater by Tony VK7AX for the enjoyment of listeners in SE Australia and Tasmania. Good on ya’, mate!
• LHS was mentioned on Joe’s (WN2SYZ) blog. Thanks, Joe!
• Dave, KG4GIY, posted another mention of LHS at Linux Journal when we talked about software-defined radios (SDR) in Episode 26. Thanks, Dave! Check out the Linux Journal amateur radio content.
• Chris, Twitter ID WOKNSS, tweeted about catching up on back episodes of LHS. Thanks, Chris!
• LHS was mentioned at the Low SWR podcast website. Low SWR is an amateur radio podcast produced by Rich KD0BJT and Brady KD0BJS. They’re up to eight episodes already! Good job, guys!
• The Axis wrote to us, Mint Cast, and The Linux Link Tech Show to thank us all for content about the Linux program screen. We’re glad you enjoyed it. A possible application might be operating digital modes remotely. (Bonus Show Notes Content: The February 2010 issue of QST has a Short Takes article about the Glentek Radio-to-Ethernet Controller. Glentek has a variety of products to facilitate remote operation of an amateur radio station. -Ed.)

Announcements:

• Texas Linux Fest is April 10, 2010 at the Monarch Events Center in Austin, TX. You might find Richard or Russ there, so say Hi!
• Donations: We’ve achieved our goal! Walter, KV6M, made a second donation (thanks, Walter!), and the remainder was supplied by Beth Lynn Eicher of the Ohio Linux Fest. Thank-you, Beth Lynn! Look for the Linux in the Ham Shack booth at Dayton Hamvention 2010. (Note: the podcast incorrectly identifies Walter as WN3LIF, another Walter that also contributed.  We apologize for the confusion. -Ed.)

Links and Notes:

• From the chat room, Ronnie K4RJJ, asks what PDAs would work with sound card digital modes. There’s i-PSK31 that will allow you to use PSK31 with your iPhone and radio. It’s also available via the iTunes store. (Note: I mistakenly said the price was $1.99. The actual price is $5.99. Sorry. -Ed.) There is also some documentation on how to wire the headphone plug for the iPhone for connection to your radio.
• Ted rants about the use of macros in digital conversations, and the panel discusses.
• The panel discusses the appropriate power levels for digital modes. Lower power, say less than 35W, is usually enough. There are devices, such as the PSKMeter, that attaches to your transmitter output and, along with software, will display your signal so you can avoid splatter. PSKScope is another program for the PSKMeter that provides additional functionality, such as automatic audio drive level control, but only in the Windows version. A Linux version of PSKScope is available, but does not have the automatic drive level control. The other device discussed is the IMD Meter, which is a standalone device that displays your IMD while you are transmitting. No computer or software is necessary.
• Next, the panel talks about operating via VHF/UHF satellites. (There’s a good introductory article on the AMSAT web site. Randy, K7AGE, has produced several YouTube videos of various amateur radio activities, including this one where he operates AO-51. Another video from the 2007 Dayton Hamvention shows a similar system.
• Bill introduces the microHAM USB Interface III. (That’s the Americas website. There is also a site for Europe. The panel discusses the merits of the device.
• We then move to a discussion of Linux Mint 8 “Helena”.
• Bill rants about Yaesu microphones on their VHF/UHF radios.
• Russ talks about some cloud computing applications: Ubuntu One and Dropbox. The panel discusses the relative risks and advantages of using such services.

Music:

• “Don’t Go” by TenPenny Joke from the album “Ambush on All Sides”.
• “Mirror of Humans” by Amity in Fame from the album “Dinner for One”.
