Heard RS-30 transmit CW during the whole pass. Below is the telemetry
received. Sounded ok. I also wonder if there is more to this satellite
the builders are letting on.

There certainly seems to be some form of picture data being transmitted. I
managed to get 41 seconds of it but may have missed a bit at the begining.
Still no idea how to decode it though.
Best guess seems to be Domenico I8CVS assumption that it's transmitting an
old format of 4 lines per second. So that's a minimum of 41 x 4 or 164 lines.
Perhaps if 50 seconds that would be a 200 line picture.
I just hope that the builders of the satellite haven't completely lost touch
with the Russian amateur community in the last few years. So far the only
parts of the transmission we can decode is the CW telemetry.
It would be a real shame if the propritory format of the data is just
intended for a small number of students within the company responsible for building
RS30 and a lost opportunity if some sort of V/U comm's has not been
included on a satellite with such an excellent orbit.
