Hi folks,
especially @fredy and @cgbsat.
The telemetry format will be published (as soon as our webmaster works) here:
http://www8.informatik.uni-wuerzburg.de/en/wissenschaftforschung/sonate/
It’s basically CCSDS source packets/transfer frames packed in AX25 frames.
Times were quite busy - so sorry about the delayed publication.
With the next pass (about 13:10 UTC) over Europe we will try to turn on the telemetry on UHF with a rate of one frame every 2 seconds for 20minutes. Additionally, we’ll try to activate a morse beacon of the callsign (DP0SNT) on our VHF (lasts about 10 seconds) for every 30seconds for the next two hours. We track the NORAD object 44400 (2019-038Q) but are not 100% sure if it’s actually us 
The idea using the S-band transmitter to identify the sat is quite neat. But we won’t turn it on until we haven’t fully acquired the satellite’s state as it’s consuming quite some power 
Cheers and always good signals
