Note also that the carrier frequency of the station, the conductivity
along
the groundwave path, and skywave propagation conditions will have an
affect
on the location of this zone, and the extent of interference there.

Richard, I think he is just too close for night time sky wave, and too far
for ground wave. When I lived in western Ohio, I had no trouble picking up
WABC with the built in loopstick. I have also picked up WABC in Bermuda and
Florida. So, I don't doubt the 27 states coverage statement. I noiced I had
trouble getting NY AM stations on the car radio in eastern PA.

BTW, You mentioned WJR. I can pick that up here in NJ, even though it is
only 10 KHz from WABC, which is about 25 miles from me. All it takes is a
receiver with *very* good selectivity. This is where the BC DX people bark
up the wrong tree when they want more antenna gain. WLW (700) became
problematic after WOR (710) went digital AM. They now broadcast hash at
least +/- 20 KHz from the carrier.
