ARISS SSTV – Expedition 66 – MAI-75 February 2022

On Feb 7 & 8, 2022, the Moscow Aviation Institute (MAI) conducted a routine SSTV (Expedition 66-MAI75 Feb 7&8 2022) experiment during orbits that pass within range of Europe and Russia. They typically operate PD120 on a downlink frequency of 145.800 MHz using the Kenwood D710E located in the ISS Service Module. I could download 4 images during 3 ISS passes.





The quality was good but not the synchronisation. I used websdr from Nürnberg http://nbgsdr.ddns.net/
and MMSSTV software.
