What make and model is the duplexer? I know of one instance that the

The first thing would be to check all

I've never had a problem. I would say that if the duplexers are out
of tune on the transmit side there is a possibility that they might get
hot, then cool off. This may cause them to take in moist air and cause

I have a 220 Motorola CDM 1550-LS and I would like to use it for the ham ban .
