Astronauts from the International Space Station sporadically establish links with radio amateurs and interview students from schools. 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.<\/span><\/p>\n<p>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. It&#8217;s not like the ground connections, where you have enough time, so the preparation beforehand is very important.<\/p>\n<p>Before you start working, stop and read this <span style=\"text-decoration: underline;\"><span style=\"color: #0000ff;\"><a style=\"color: #0000ff; text-decoration: underline;\" href=\"https:\/\/www.amsat.org\/fm-satellites-good-operating-practices-for-beginning-and-experienced-operators\/\" target=\"_blank\" rel=\"noopener\">good operating practices<\/a><\/span><\/span>.<\/p>\n<p>For mobile devices, this widget looks better in LANDSCAPE<\/p>\n<p><script>\nvar norad_n2yo = '25544|ISS,40654|PSAT(NO-84),26931|PCSAT(NO-44),25338|NOAA15,28654|NOAA18,33591|NOAA19';\nvar size_n2yo = 'medium';\nvar allpasses_n2yo = '1';\n<\/script><br \/>\n<script type=\"text\/javascript\" src=\"https:\/\/www.n2yo.com\/js\/widget-tracker.js\"><\/script><\/p>\n<p><span style=\"text-decoration: underline; font-size: 14pt;\"><strong>RADIO<\/strong><\/span><br \/>\nIdeally, you need an all mode VHF\/UHF transceiver, like the old <a href=\"https:\/\/www.yaesu.com\/indexVS.cfm?cmd=DisplayProducts&amp;encProdID=8CBB7C4BDBAF40129AD4253A4987523C\" target=\"_blank\" rel=\"noopener\"><span style=\"text-decoration: underline;\"><span style=\"color: #0000ff; text-decoration: underline;\">Yaesu FT-857<\/span><\/span><\/a>, or the newer fancier <a href=\"http:\/\/www.icomamerica.com\/en\/products\/amateur\/hf\/7000\/default.aspx\" target=\"_blank\" rel=\"noopener\"><span style=\"text-decoration: underline;\"><span style=\"color: #0000ff; text-decoration: underline;\">ICOM IC-7000<\/span><\/span><\/a>. First of all, the transceiver must be connected to the audio interface of a computer. Received audio signal go to LineIn-soundcard and Speaker-soundcard must reach the station&#8217;s microphone &#8211; for transmission. All solutions are already described on the net. Some stations have a dedicated connector for this. It resembles the PS2 computer jack.<br \/>\n<img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" class=\"\" src=\"https:\/\/i0.wp.com\/wa8lmf.net\/6-Pin-MiniDin-Data-Connector\/MiniDin-6-Female.gif?resize=261%2C117\" alt=\"Image result for ham radio data connector\" width=\"261\" height=\"117\" \/><\/p>\n<p>There&#8217;s still the PTT problem.
