I have a IQ recording on https://pe0sat.vgnet.nl/download/TRISAT-R/, I have also created a telemetry.log file.
All output forwarded to this file, I see the master_channel_frame_count
is increasing.
Thanks! I also went ahead and decoded that file on my own, before you uploaded the telemetry.log
.
It indeed seems to contain the same CCSDS frame structure as TRISAT, and appears to be used more or less correctly.
There is by the way a bit of profanity (I guess virtual channel 7 is for Only Idle Data):
-> Packet from 1k baud FSK downlink

Now that we know that the telemetry format is correct, I'm going ahead and merging this.
