Why? I don;t see any reason why not. I do, of course, see a reason
with low VHF, at the present power levels and error correction levels.

NO NO NO ... you seem to have some misapprehension here. The screaming
of a very tiny number of people is "multipath" but in the REAL world,
it is power level.

Lots .... if it got them free HDTV and they live in rural areas.
You seem to have the idea that everybody lives in a "city".
Low VHF will be ideal for Montana and Alaska. True, it will be better
to use higher powers than are now postulated for digital ...
average powers in the 200-300 kW range for low VHF would be best.
