Amateur Radio on the ISS

On board the International Space Station (ISS) is an amateur radio equipment that can be used to transmit voice and encoded data. The ISS transmits an audio signal at 145.8 MHz in SSTV format, in which a series of tones can be heard that when decoded by an appropriate program, it will form an image.

To receive SSTV images, you need a two-way radio and a decoder app. Any radio that can be tuned to 145.8 MHz can be used. I am using a Yaesu FT60, but just about any radio would work. I use Robot 36 app to decode the signal. To watch a demo video, click here.
