Is anyone using this particular combination with the Fox 1 Telemetry Analysis Tool? Today on one of my good passes with AO-91 I believe it was transmitting high speed telemetry and it seemed no matter what combination I used, I could not get the tool to decode the high speed telemetry. I have no problem with the low speed Data Under Voice with this combination. I have always assumed that the high speed telemetry is on the same frequency as voice and low speed DUV. I would appreciate any thoughts anyone has as usual. Best Regards, Fred – KF4FC
Fred,
What bandwidth did you set for the FM channel in sdr#? You can decode the DUV slow speed telem with a 5kHz channel but the high speed needs to be 15-20kHz.

Hey Fred!
At https://www.amsat.org/getting-ready-for-radfxsat-fox-1b/ there's a comment that indicates that all the telemetry from AO-91 will be of the "low speed" variety:
------ Satellite and experiment telemetry will be downlinked via the “DUV” subaudible telemetry stream ------
... also, on the telemetry page ( http://www.amsat.org/tlm/leaderboard.php?id=2&db=FOXDB), as of now anyway, no 9k6 packets have been received by anyone.
73!
