DTV on standard NTSC TVs

[Jeffhs]

If you cannot receive the Seattle stations where you are with an antenna, and satellite doesn't carry Seattle's locals for any reason (what about Spokane stations?), your only other option would be cable if your area has it.

I would think, in an area over 100 miles from Seattle, you would have at least one cable system -- unless you are way out in the boondocks. If you are located in eastern Washington state (I don't know where in the state your town is), you should be getting stations from Spokane and also across the border in British Columbia; since the latter, and for that matter all TV stations in Canada, now have converted all their TV stations to DTV, one converter box on your TV should do the trick if you still want to use an antenna.
