Erie is about as far from me as one can go and still be in PA. Anyway, I believe it's true that low power TV stations can continue transmitting NTSC.
Concerning the transmission range from lookout:
Lookout 7374 feet AMSL
Tower + 800 feet
Denver - 5280
2894 feet above service area (h)
Distance to horizon (mi) = 1.34 * sqrt(h) = 1.34 * 54.6 =
about 73 miles
Receiving antenna at 25 feet
Distance to Horizon = 1.34 * 5 = 6.7 miles
Total distance is about 80 miles
Perhaps a bit less since the prairie land east of Denver is falling off in altitude.
Anyway, its just an estimate.
