Mike, another thing to consider is water in the RX line or dish horn

We had a 4-ft Marti dish where the feed horn cracked and allowed water to enter, one
channel was still 'full bore' while the other was down in the noise

If you have a spare TX (or can strap your TX et-up to mono and pull one of those), then
hook a TX to the RX line and see if you have high VSWR
