Works fine on a dummy load, so the problem is after the duplexer.
Using Superflex jumpers, so no copper-braided coax problem.

Got any security cameras at the site? Wouldn't explain the scratchies but
I've had problems with those too. 38th harmonic of 15.75 kHz horizontal
sync = 598.5 kHz, mixes with output to land on input.
Also check other antennas near yours. I've had nearby Stationmasters with
internally broken elements cause major scratchies on my 2 meter
system. Just send someone up the tower to shake each nearby stick
individually while listening for the noise.
