Hello Lee - first step - dummy load and isolated tee. Terminate the output of the duplexer into a dummy load. Insert a 'T' connector between the duplexer and load. Have a gap of abt 1/4" between the side terminal of the tee - have good connection between the duplexer and load.
Inject a -70 or so signal on the rx freq into the tee (enough to open the receiver with the transmitter disabled) - turn the tx on and off and see if there is any desense without external sources introduced by the antenna. If all is well, repeat test with dummy load in place of antenna. This will show an anomaly in the antenna system that a watt meter might not reveal. Used to have lots of trouble with loose connections on db224 exposed dipole antennas.
