Sure, BUT... in addition to the channel 22 NTSC a couple of miles away, and WNLO about 70 miles away, there's the CN tower about 35 miles away. This broadcasts dozens of high power signals, mostly ATSC.

So the strange part is why can I get a perfectly good ATSC on channel 33 from 70 miles away, but nothing whatsoever from a bunch of powerful channels half that distance?

It seems the system is either *astonishing* directional, or *astonishingly* tuned to specific frequencies. Neither seems terribly likely!

Or perhaps the tuner skipped channels... I'll check that tonight.
