By keeping one's positions vague enough, I suppose one can make all
sorts of claims.

If you take five adjacent, large markets in the East Coast, Wash/Balt,
Philadelphia, NYC, Hartford/Sprinfield, and Boston, you have already
achieved what you are saying. It is very unusual to receive Phildelphia
stations within Baltimore or Washington, but at the same time, those
living between Philadelphia and Baltimore can and should be able to
receive stations from both markets, without interference. Ditto to the
North of NYC and South of Wash.

NYC uses the same channels as Balt/Wash. Philadelphia is the market
between them. And Boston uses the same channels as NYC as well, with
Hartford/Springfield intervening between them.

This is as it should be, considering the size of these markets and the
reality that people in communities between the cities often commute to
one or the other for work. I don't know what greater reuse you think
makes sense here.

And if you want to set up LPTV stations within Philadelphia proper, for
instance, this should be possible on the same frequencies as used in
either NYC or Balt/Wash.

All you're saying here is that you prefer rural communities not to have
any significant TV coverage. Say, where Cliff lives. You would prefer
that Cliff have no OTA TV access at all, other than perhaps some
local-yokel station.

I'm saying that this is not a good plan. There's no logical reason to
create areas with no OTA TV coverage up and down the East Coast. It is
all inhabited, even if some parts might not have dense population. Nor
is there any reason to think that a significant number of TV stations
would survive if they only served sparesely populated communities. Why
handicap OTA TV that way, when clearly it's not an emphasis on "local"
that makes DBS and cable successful?

I'm all for a more enthusiastic OTA TV system. IMO, it's not *large
area* SFNs that will make the (positive) difference here. On-channel
repeaters are, of course, a different matter entirely. And low-power
translators.
