Gang,
Some 50 years ago, late at night, I’d listen to radio station WWVA out of Wheeling, West Virginia. They were a powerhouse, 50,000 Watts (the legal maximum in the US) “Clear Channel,” (meaning that no other domestic station had that frequency). AM stations bounce their signals off the ionosphere, and when that layer gains altitude at night, a clear channel station can be heard many hundreds of miles from the transmitter. (Dick Summer on Boston’s WBZ, another 50K CC station, got fan mail from Guam on one occasion.) Read the full story . . .
