I hate to say it, but you've wasted a lot of money while ignoring the root of your problem that's right in front of you - that million watt PBS station straight in the line of sight less than 7 miles dead ahead. It's causing almost everything to overload.
Sell/return everything except the 91XG and perhaps the KT-200. Take that money and call Tin-Lee up in Toronto and tell them you need a very sharp and deep channel 23 notch filter. Ask for at least 30 dB attenuation, 40 would be better. Expect it to cost up to several hundred dollars.
Then, for an amp, select either the KT-200 or a CM or PCT 1-port Distribution amplifier with a remote power inserter and install the amp at the mast head.
You'll then be in the ballpark, at least.
