 === Thanks for the explanations. 
 
 Lots of factors involved. I wonder if this
 never-ending heat wave we have now is contributing
 in some way as well. It's 30-plus-C [about 90-F]
 with maximum humidity.

 I'd guess less than 100 miles? Probably around
 50-60. The transmitters are up in the Vermount
 mountains and upstate New York. One of the stations
 signs off with "... from high atop Mt. XXXXXXXXX."
 Then the terrain from there is about as flat as
 flat can be, ie. the transmitters are beaming the
 signal down on us.
