I have a little more to answer before I do CH2.
For the images I posted, I had to know your exact antenna location coordinates, which I don't have, but I think my estimate of your location is pretty close.

Meanwhile, I essentially get nothing that's listed below an NM of -10...even though I have stacked Yagis (should be good for at least 10 dBd) and a preamp that's good for at least 28 dB.
It is difficult to receive any signals with a NM of less than -10 dB. If you do receive a signal that has a NM of less than -10 dB, you have an excellent antenna system, your tvfool report is wrong, or they have been enhanced by Tropospheric Propagation.
