I just wrote this to Btech Support:
There is a problem on the receive side. Signals have a high level of noise . Understand that other radios with the same antenna and feedline do not experience this. I found by accident that if I touch any of the front panel buttons or some of the buttons on the microphone the received audio become clear and the noise level drops to full quieting. This is repeatable. But it only lasts until the incoming signal stops. The next transmission is very noisy and the audio is low. Until I push any button (like momentarily pushing the on/off volume knob, the scan button, monitor button, or other). Then the cycle continues.
Possibly related to the OP problem. Just for the search engines...
