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.)

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  • SAREX (Shuttle Amateur Radio Experiment) has been superceded by ARISS (Amateur Radio on the International Space Station).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