LHS Episode #035: Soylent Green is Bad Apples

Posted on by Russ Woodman

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!

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  • SAREX (Shuttle Amateur Radio Experiment) has been superceded by ARISS (Amateur Radio on the International Space Station).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.
