Re: QCX-SSB: SSB with your QCX transceiver

Yes, that is what happens in the old version when Q6 bias/operating-range is off, and it makes totally sense because the key-shaping was actually only designed to switch a CW signal. You might want to try out the new version which removes C31; the circuit behaves more stable and linear, it is then digitally switched with the PWM signal.
Sorry to hear that you found the sample not all that good, it is always quite subjective; the signal indeed was quite weak at the moment I took the video, maybe the signals are easier to copy when the propagation is better?...or maybe this software driven SSB will always sound terrible?...
