I agree that monitoring into the speakers is a real problem with feedback. My whole point was that I want to be able to monitor the TX signal into the line out only (with level independent of the AF gain control). This is very useful, including the ability to judge the transmitted signal using the recorded audio. Judging the audio is nearly impossible to do in real time using headphones.

The problem I see with that is feedback. Having a speaker and a live mic in
close proximity to each other is an invitation for serious feedback hum.
Think of people that call in to radio programs, there are always a few that
leave the radio on, and have to turn it down.
