Umm, you typed WTUV, not WVUT in post #6; obviously a typo, John.

You guys were right I think about the variable gain on amp causing the signal to seem skewed on antenna.Thanks a bunch for the info and help.
WVUT is much weaker than your strong local signals. It got wiped out from overload AND it has possible adjacent channel interference from W23BV on real channel 23. The highlighted "a" next to the WVUT callsign in your report indicates adjacent channel interference; the highlighted "c" indicates co-channel (same channel) interference.

WVUT will be moving to channel 31:

This is the point: Because of the very strong WTVW, you need a separate antenna and preamp, not an antenna with an integrated preamp. They must be separate because you need a filter between the antenna and the preamp to attenuate WTVW.

The only other alternative for your location is just an antenna with no preamp.
If you can not measure it, you can not improve it.
