[TheList] UBC-9000XLT Fault

Hi Folks,
How many of you guys own one of these scanners?
I've had mine for about 6 years, it has all of a sudden stopped 
receiving anything at all.
A couple of years back, the squelch stopped working (as in wide open all 
the time),
so I installed a discriminator tap to run PDW for Fire Paging and turned 
the volume right down.
Now, the thing is as deaf as a post, I opened it up, couldn't find 
anything obvious, put it on
a signal generator and a 'scope, as well as an audio signal tracer, it 
all tests out fine, yet if I
trigger a VHF handheld next to it, with a simple aerial connected to it, 
it doesn't want a bar of it.

Any thoughts?
