Received audio signal go to LineIn-soundcard and Speaker-soundcard must reach the station’s microphone – for transmission. First of all, the transceiver must be connected to the audio interface of a computer. Ideally, you need an all mode VHF/UHF transceiver, like the old Yaesu FT-857, or the newer fancier ICOM IC-7000. It’s not like the ground connections, where you have enough time, so the preparation beforehand is very important.īefore you start working, stop and read this good operating practices.įor mobile devices, this widget looks better in LANDSCAPE Most of the connections are in the VHF / UHF, are made with low power (4-5W are sufficient) and last very little, maximum 10-15 minutes, because this is what it takes the satellite to pass over your head. You can receive all these transmissions, plus there are SSTVs with anniversary occasions, communications between EVA participants and other stuff that occur all the time. Astronauts from the International Space Station sporadically establish links with radio amateurs and interview students from schools. There are many satellites for amateur radio traffic, either digital or voice repeaters, or that send weather maps with the earth from space.

I thought about putting together some helpful information for working on satellites, a very beautiful and challenging area, where the efforts are fully rewarded.
