Hi Steve, It is separated by a relay but that doesn't mean that you can't damage internal circuitry. If you hear relay clicking sounds while you are transmitting then you have tripped the protective COR (carrier-operated relay). If this occurs then you need to reducer power or separate your antennas more, and/or provide external protection.
The diagram on page 42 of the K3 manual illustrates the presence of the COR(s). 73, Mike K2MK K4FJ wrote > Am I correct in assuming that the Rec Ant input is disconnected from the > main receiver input upon transmit by way of a relay?
