What other Canada and USA TV stations are around Lake Placid New York?... besides
W55AI Channel 55 Lake Placid NY C-22 FCC Licensee Subsidiary, LLC Lambert Broadcasting of Burlington
WPTZ Channel 5 North Pole NY Hearst-Argyle Stations
WCFE-TV Channel 57 Plattsburgh NY Mountain Lake Public Television Council
Best information I have is that W55AI has been deleted.
The FCC's propagation curves program suggests the following stations should deliver a usable signal to Lake Placid:
WCAX-TV channel 3, Burlington, Vermont (RF channel 22) CBS 3.1, news 3.2
WPTZ channel 5, North Pole, New York (RF channel 14) NBC 5.1, MeTV 5.1
WVNY channel 22, Burlington, Vermont (RF channel 13) ABC 22.1 & 22.2
WNMN channel 40, Saranac Lake, New York (RF channel 40) RTV 40.1, Antenna TV 40.2, My 40.3, A1 40.4, AMG 40.5, RSN 40.6
WCFE-TV channel 57, Plattsburgh, New York (RF channel 38) PBS 57.1, MHz 57.2, PBS World 57.3
Curves is not the gold standard for DTV coverage, your mileage may vary!
WFFF, the Fox affiliate out of Burlington, is relatively low powered and not predicted to reach Lake Placid. No Canadian station really makes it either -- the closest seems to be CJOH-TV-8 channel 8 out of Cornwall, Ontario (analog).
