I am hoping WNYF will come in no trouble...as I said before WNPI is always on with plenty of signal and WCFE is no trouble on any night so long as I point the antenna in that direction. I get wwti about 40% of the time so far.
Mike, I think you are in a great position to get WNYF-LP (18/28.1; FOX-SD/CBS-HD), WNPI (23/18.x; PBSx3), WCFE (38/57.x; PBSx3) as well as all the locals. But WPBS (41/16.x; PBSx3; -20.3 dB Noise Margin), WWTI (21/50.x; -21.8 dB NM), and WWNY (7/7.x; CBS-HD/FOX-SD; -6.3 dB NM but VHF-HI) will be big challenges to get more than intermittently, unfortunately. Recent weather conditions have allowed much better signal propagation than normal. (I've been picking up channel 35/28.1 FOX from Watertown occasionally over the past few weeks -- definitely abnormal.)
Back to that CM-7777 preamp: Please check out this chart (hope this link works -- if not, see the first post in the Signal Amplifiers thread):
The CM-7777 maximum input for two strong VHF channels is -29.8 dBm, -35.8 for UHF. (Reduce by 3.6 dB if 3 strong signals, 5 dB for 4, 7 dB for 6, etc.) Your tvfool report shows channel 4, 9, 13, and 6 all above the VHF levels, and several of the UHF channels also coming in hot. Once the preamp is driven into overload, results will become unreliable and unpredictable.
Here are some suggestions, and I hope the forum experts will chime in with feedback and criticisms:
a) Depending on the cable length from your antenna to your splitter/tuners, consider eliminating the CM-7777 completely.
b) If you are mostly interested right now in just the digital channels, I'd suggest that you get a UVSJ and a 75 ohm termination. Aim the 4228 between South Colton (151 degrees) and Plattsburg (122 degrees). Connect the 4228 to the UHF port on the UVSJ, and the 75 ohm termination to the VHF port, and connect the joiner output to the CM-7777 input. This should help attenuate the hot VHF signals from CF.
c) If you also really want the analog VHF channels, get a low-gain (simple dipole?) VHF antenna, and run a separate cable for it down to where you have your splitter/tuners. Connect this to the VHF input of another UVSJ, the tv-side feed from the CM-7777's power supply to the UHF input, and this joiner output to your splitter/tuner input.
A long post, but I'm really hoping to get some feedback/discussion on these suggestions.
