The International Space Station (ISS) has been transmitting images since October 28 and will continue to do so in the next few days. It transmits in SSTV format—the same format used to send images to Earth during the Apollo missions. The transmissions can be received with any radio tuned at 145.8 MHz, and a decoder app such as Robot 36 (try installing that app and decode this recording).
In the previous post, I have mentioned that I am currently engaged in amateur radio activities, particularly, satellite communications. At the moment, I am only receiving transmissions from the International Space Station (ISS). Shown below is the gear I use to send and receive SSTV images.
Equipment for Sending and Receiving SSTV Images
- Transmitter (Motorola CP1660) + DIY connector (smart phone’s line out to transmitter’s microphone in) + encoder (smart phone with SSTV Encoder app)
- Receiver (Motorola CP1660) + DIY connector (transmitter’s line out to smart phone’s microphone in) + decoder (smart phone with Robot 36 app)
