SSTV October 29, 2018, 241 am 4G1AWN

SSTV image received and decoded from the International Space Station (ISS) as it passes over the Philippines on October 29, 2018, around 2:41 local time

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)
SSTV RX TX

Through amateur radio, you can engage in various activities such as receiving images from the ISS, use various satellites as relay stations, bounce a signal off the moon, or talk to the astronauts on the ISS (as it orbits 400 kilometers above)!
