Joe, If you can get hold of a TDR that worked well for us to find the
problem. If also is a easy method to test for antenna problems while
still on the tower. We had a Stationmaster with a bad solder joint
and it was causing desense in windy days. Found and fixed with the
TDR. Also we had problems with guy wires causing noise in the system
and fixed finally by installing Phylistran guys.

the local club repeater and replacing it made our noise problem go
away. I've taken it apart and inspected it for cracks in the joints
but can't find any. I've been thinking of sending a 12VDC voltage
through it using a ballast resistor and looking for the warm joint
with a handheld thermometer we just got at work. With enough current
going through the joints, I should be able to detect the bad joint.
