HI, we have a GR500 cross-band repeter, and he is going on transmitting with no reason. I checked criteria: on RX radio, pin 8 (PL detect, low active) and on TX radio, pin 3 (PTT, low active) on assesory connectors when everything is connected, also by scope (DC and AC) and everything is all right! Cables are also good, and we dont know what is going on. Usually it work all right, but sometimes GR is going on transmitting. Do you know what is wrong?

"on RX radio, pin 8 (PL detect, low active)"

You need to program pin 8 to PL + Carrier to activate. PL only CAN false to easaly.
