Hello dean,
I have previously used “High-Speed SoundModem by UZ7HO - Ver 0.12b - [GMSK USP 9600bd]”, which was published by sputnix, to successfully decode telemetry data from QMR-KWT-2 and SAKHACUBE-CHOLBON at 9600 bps (GMSK USP).
However, I have not yet been able to decode the telemetry of SAKHACUBE-CHOLBON at 2400 bps (GMSK USP).
73,
