Wait you are a ham.  Do you have a 2m rig on board?  If so you can try
that antenna for receive and see what you get.  Even if it's just a hand
held antenna with an adapter to go from UHF to BNC.  

There are a few things you can do to try to test out there but nothing
that is going to be exact.  

Does the radio have the weather channels on it?  If so how do they come
in?  

I would hate to have you start doing anything internal on the working
radio since it's your lifeline if you have a problem.  I would however
start looking at the other one to see what you can do with it.  Have you
tried disconnecting the mic from that one?  I have a VHF radio that
seems to have some problems in the mic and it goes into different modes
even when I am not touching anything.  Start there then open the thing
up and look for anything out of the ordinary.  

We may need to find a way to ship you a radio to use while you ship
yours here so that I can throw it on the service monitor and see if it
is the receiver front end.  

Are you planning to be in Florida any time soon?

Hi, Dave,

Sorry we'll miss crossing paths...

The rx on 68 has been troublesome for more than a year.  I'd thought it 
maybe an anomaly in GT based on where folks were txg from, but it's
severe 
here, so I conclude it's the same thing.

I agree about affordability of repair, and I'm not adequately equipped
for 
component-level repair, but I think I'll be able to chase that down
(antenna 
feed or radio) relatively shortly.
