I did go out and turn the transmit radio off and when ever the receive radio receives a signal from a GMRS radio like it is programmed to it also receives the scratchy noise and in the background I can barley hear the PD talking. The receive radio is a Maxtrac 2 CH 25 watt radio. I have a homebuilt repeater controller that I constructed myself with CAT 5 cables going into the mic jacks on the radios if that would have anything to do with the shielding on them. Also a COR was modifyed on the Maxtrac to one of the mic pin jacks to have a audio and COR out.
