I would like to see this facility as well. I always feel silly asking about my audio when using VOiP, but things can be "not quite right" and to hear the audio fault might go a long way towards a "self help type of correction".

When you are transmitting with your "real" radio what means have you to test your audio quality? On my transceiver the only test is the audio level. No indication of the quality of the audio. I leave that to others to tell me. Why should CQ100 be any different?
