Jim, This IS interesting! Just for grins, try disconnecting the external controller and set up the MTR2000 as a repeater. It's very important to set the activation and hold-in options to "carrier and PL/DPL" as I mentioned in an earlier posting. I suspect that the external controller is bypassing the audio during hang time, and allowing the rogue signal to enter. If the symptom goes away when the MTR2000 is operating autonomously, the problem lies in the external controller or possibly the way it is connected.
Another thing to try is to set the TX Idle frequency away from the TX frequency. Try setting it to 144.0000 MHz. 73, Eric Lemmon WB6FLY "Jim, K8COP" wrote: > Eric, > > I forgot to include that the station is used in the "base station > configuration".
