I often bounced digital packets through the ISS repeater, but it took a while before I was lucky enough to make voice-contact with an on-board astronaut. A while back AO-40 offered *long* visibility periods with many conversation over a large footprint, but required equipment that listened in S-band for the downlink: not everybody was ready to hack that up. It also suffered somewhat from earthbound interference due to unlicensed Type-15 WiFi equipment; fortunately directional antennas nulled most of that out. An unfortunate error in launch prep for the engine on-board AO-40 resulted in loss of much of the equipment on board, yet it remained operational in a limited fashion until a battery failed to a shorted condition. Optimists hope the shorted cell may open someday; this is not unprecidented and actually happened on AO-13. 73 de K3XS @MaggieL, who probably won't get disemvowelled this time. True dat.

Just like a train whistle, the frequency of the transmission varies. In this case, you must adjust the uplink and downlink freqs to compensate. It is usually easy enough to do manually. Keep in mind these sats are not geostationary. -n9ybx <!-- www.hack.net --> Sure- think of it this way- half of the “pass” above you, the satellite is moving toward you, and half away from you.

Also, I always feel a bit badly for Uda when I see mention of a <a href="http://en.wikipedia.org/wiki/Yagi_antenna#History">Yagi antenna</a>. There's some effort now to refer to it as a Yagi-Uda antenna, but the name's probably stuck now. Basically, Uda came up with the initial idea. Two years later, Yagi helped to improve the design somewhat, but more importantly published the first description of the design in English. He never sought to usurp Uda's design, but the name Yagi stuck because it was on the paper westerners were reading. What a great photo. I’m in Ham-nerd love.

I was thrown by the comma -- I read the sentence to mean that she was tracing the orbit to compensate for the doppler effect. Of course, it makes sense now: she has to continuously adjust the tuning frequency as the component of the satellite's motion toward/away from her will be continuously changing. This also inspired me to poke around some on wikipedia, so now I finally understand what 'satellite eclipse' means. (It's mentioned under observations/satellite on this weather site http://www.cwb.gov.tw/eng/index.htm , but with no explanation, at least not in English.) I learned a lot here today! Thanks!
