Amateur Radio on the International Space Station (ARISS) slow-scan television (SSTV) transmissions are planned for Cosmonautics Day, Saturday, April 11 from RS0ISS in the ISS Russian sector.
Cosmonautics Day celebrates space pioneer Yuri Gagarin’s April 12, 1961, as the first human to reach space.
The SSTV event will get under way on April 11, 1000 UTC on 145.800 MHz. All transmissions will use SSTV mode PD180. As for prior SSTV events, 12 different photos will be sent through the weekend with 3 minute off periods between transmissions.
Receiving the SSTV images requires a 2 meter receiver/transceiver and a PC to convert the audio to an image. Software such as MMSSTV is available free on the Internet. Received images may be uploaded and viewed at the ARISS Image Gallery at
Unanticipated events on board the ISS may cause any scheduled ham radio event to be postponed or cancelled. Check the ARISS Facebook page for updates.
