The minimum contour for FM stations to get significant listening is
the 64 dbu, roughly 1.5 mv/m.

You guys throw a lot of listnership away if you're requiring 1.5mV/m..
since even cheap POS radios have FM sensitivity down in the low hundreds
of microvolts, and good ones (home and car stereos) are good down to 5-15
microvolts.. you're almost a full order of magnitude higher than the
average car stereo... (order of magnitude = 1x10E3)

We are talking exclusively of home and workplace reception, as there is no
way to track the ZIP of in-car listening. Since in home and at work account
for 70% of all listening, this is more than adequate for study.

Listeners, not stations, make the decision of what stations they will listen
to. And listeners do not listen to signals weaker than 64 dbu in 96% to 97%
of the time spent listening to radio. In other words, if the signal is not
above a certain strength, listeners.... whether in Miami, LA, McAllen or New
York, to name a few... do not use them.

Stations are not "throwing away a lot of listenership" because listeners do
not like weak signals and won't listen to them.
