And analysis of millions of listener weeks of recorded listening over
nearly a decade shows that there is very little listening outside the 64
dbu of FMs at work or at home, and much of that is because the radios of
the last few decades can't pick up much of anything less than that with
acceptable quality. When I see nearly no exceptions that would validate
your contention, I must conclude that you are imagining things.

How many of those studies were done outside huge metros?

I've lived in towns with their own FM's where the 64 dBu contour didn't
cover the transmitter site parking lot. One example was KLER-FM in Orofino,
ID. Their tower was BELOW average terrain, and they were running 100 watts,
and couldn't cover a significant portion of the very small town they are
located in. Since then, they have raised their tower height and power, but
given the terrain, probably don't have a much better coverage. It may be an
exaggeration, but not much of one, to say that some educational stations
wouldn't have a 64 dBu signal if you connected the meter directly to the
transmitter..
