There's a great document on the RB website that discusses desense. If you
haven't looked at it, I'd definitely recommend it.

Thanks Oz for the comments.
You are right it could be the duplexer, but my money is still on that used
antenna.
I know when I moved the duplexer to here, I had it wrapped in a blanket and
strapped in to the car seat like a baby.
I found a document on hooking a handheld to the transmit side and adjusting
for maximum output. Guess that is my next step since I don't have a service
monitor.
