We're attempting to set up a repeater using 16 channel GM300's and an external controller (a CAT 1000).
We've done this before twice, but seem to be stumped this time because we can't get either the receiver radio or link radio to produce the right voltage swing the controller is looking for in connection with COR. We've tried 3 radios but none will produce the necessary voltage swing. What have we missed? Programming or wiring issue?
