Why are you introducing any reality into this debate? What was the antenna
criteria? What noise figures for receivers were used? Did they employ
free-space, R-6602 or some other signal loss criteria?
You don't have much geographical (hill/mountain? limitations in Illinois,
but how (if at all) were those figures included in the data set?
Who provided the source data (the FCC's old databases are NOTORIOUSLY
inaccurate) and could they provide the names of the actual engineers that
did the calculations, or the programmers who wrote the algorithms?
Who verified the maps against the data? (I suspect nobody.)
Here's the nub: who not in a mental hospital (or working against
broadcasting) thinks that any broadcaster wants to reach fewer people with
digital than with analog. In other words, why do we have to devote any
effort and energy to overcome a problem that broadcasters will either solve
individually or will suffer collectively as a result of?

At least for Illinois, those maps are highly inaccurate,
especially for CBS.
The show what it would be if every station were at full
height and power, and CBS Chicago were at an adequate power
for being on Channel 3 (i.e. 50 kW).
CBS in Chicago, Champaign and Peoria are at very low power (2 kW),
channels 3 and 48 and ?. None is anywhere near adequate, though
Chicago is officially "full power", to cover their analog areas.
NBC in central Illinois is also low power, as is Fox in
Peoria. Fox is not even on the air for east central Illinois
(though in Champaign we see the benefits of high power UHF
digital as most of us get reliable reception at 60-70 miles
from Springfield.) They were supposed to be on as Fox went
HD, but some part is missing .... due to software. A pointed
question: is this missing software being written in Tiajuana :-) :-)
The low power stations near me do, however, cover the city of
license quite well.
