ESA Education has released tutorial videos explaining how to make use of various computers and mobile devices to receive the International Space Station SSTV transmissions on 145.800 MHz FM that are expected for the 45th anniversary of the Apollo-Soyuz mission.
Apollo–Soyuz was the first international space mission, carried out jointly by the United States and the Soviet Union in mid-July 1975 and ESA Education say the anniversary will be marked by SSTV transmissions from the ISS.
