Anybody out there successfully configure the SUB-RX for HI tones (2125Hz mark)in FSK-D? I can't seem to do it. A->B all doesn't work. BSET apparently doesn't recognize the pitch control used to set this. Spectrogram clearly shows low tone audio being output. Firmware 2.8x being used here. Other lower versions didn't work either. 73 de Brian/K3KO
