I have tried this method and it works well with my non-BITX 5w CW
transmitter. My receiver has an RF preamp and a post mixer
amplifier. I found that if I grounded both transistor bases during
transmit with a transistor switch, the transmit signal would be
attenuated enough to be used as sidetone (no audio section mute.) I
think this would work for SSB with lower audio output.
