Put a different radio in as the receiver and tried 2 different configurations for the controller and the behavior was about the same. So it looks like I'm down to desense. The jumper cables from the radios to duplexer are of an unknown type. The cable to the antenna is RG-8. Or it could just be repeater location. Thanks for all the help. Craig
