I've had and seen various analog TV's that would have to do a new channel scan every time the power went out. But with an analog TV the antenna likely pulls in a snowy ghosty signal even when pointed in the wrong direction for the channel.
If you do the same thing with a digital tuner the channel likely won't even be found by many tuners. That may prove annoying.

It's the problem of IM3 distortion. Why make it sound like it's a brand new discovery? I agree that use of white spaces is risky, and IM3 makes it even more risky. This also holds for COFDM. "The fact that more than one U signal can result in interference, even when both U signals are below their threshold power levels (measured separately), makes the interference possibilities simply terrifying when unlicensed transmitters begin to share broadcast spectrum on Feb. 18, 2009. Stay tuned." As to professional installation FUD, what is that trying to prove? Is it any different for professional installation of cable and DBS? Any of these guys can use Channel 3 as a shortcut, big deal. As to the chicken-egg problem of scanning DTV channels initially, when analog channels will no longer be there to help, how is that any different with COFDM, and especially with low power COFDM? The answer, obviously, is to use the various aids made available by the CEA (e.g. antennaweb) or equivalent in other countries.It is not just that 8-VSB is a c**p modulation like I said. In fact it is the attitude of Congress and the FCC and frankly most broadcasters that allowed 8-VSB in the first place.8-VSB is irrelevant in all of this. The problem here is unhelpful FUD and hype.
