ISS SSTV- "Amateur radio on Shuttle, Mir and ISS" SSTV event - June 21-26 ,2021

    Talking about history … The Shuttle–Mir program was a mission space program between Russia and the United States that involved American low earth orbiting Space Shuttles  visiting the Russian space station Mir where Russian cosmonauts flying on the American Shuttle, and an American astronaut flying aboard a Soyuz spacecraft to engage in long-duration expeditions aboard Mir.

   SSTV event was continuous from June 21 until June 26. The images transmitted were related to some of the amateur radio activities that have occurred on the Space Shuttle, Mir space station and the International Space Station.

    Used this event to test multiple antennas. Experimented with two different antennas this time, One was QFH tuned to 136 MHz obviously for WX satellite reception and one was Slim Jim antenna tuned to 145 MHz. And another setup was with VFH-UHF Yagi antenna tuned to 145 MHz frequency in VHF range. 

    The result was as expected the tuned antenna closed to downlink frequency of ISS VHF Transponder i.e. 145.800 MHz gave better results. Managed to receive few good images using my Yagi on last days of event.

Two images on the left side are from QFH and two on the right side are from VHF/UHF  Yagi positioned to ISS during specific pass.

    Thanks to all those Ham radio communities and clubs around globe for providing event participation SSTV Diplomas on successful reception of SSTV images from ISS. This will really encourage and promote school students and other enthusiasts towards Space Station and Space explorations. Received few certificates of this event.
