Can you get into the receiver to clamp the AGC voltage at a level
that minimises the receiver sensitivity when the transmitter is off?
I am thinking that a simple diode arrangement onto the AGC line could hold
the AGC voltage at a level that minimised the noise pulses out of the
receiver, but still gave sufficient room for the AGC to follow the
transmitted signal when that is on. This would at least give a first
solution to the problem.

As to the business of ensuring the CCP value is correct, I am sure that I
have seen items about this on the PICList in the past, maybe time to check
the archives Scott ?? :)
