I traced it to a bad UHF union in the feedline. Exact same symptom as a

Was it an Amphenol-branded or surplus MIL spec? Or was it a no-name
knockoff? I would suspect the latter.
When I got back on the air in 2003, I stocked my junk box with all sorts
of adapters from hamfest vendors, and over the next 5-6 years they
caused me no end of problems, most of which were difficult to track down.
I got religion and stocked up on REAL adapters, either MIL-spec surplus
or Amphenol parts. Yes, they cost a lot more, but doing brought an end
to those problems.
