AM Radio coverage

[Russ Butler]

Speaking of AM radio station coverage on this list recently, I remember 
that it wasn't unusual for WBZ's Norm Nathan's late-night telephone 
conversations to include a caller from London or other countries "across 
the pond" with their Hull, MA salt water-grounded transmitter site.

Also, I found this comment online from John Rook (dot) com, a former 
Program Director at KFI in Los Angeles:
/
KFI, at 640 on AM dial in Los Angeles is known as the nation’s most 
powerful radio station. Listeners from Hawaii to New York and Canada to 
Mexico for years tuned in to hear Dodger games exclusively on the 
station. The premium facility had been sold to Cox Communications of 
Atlanta for a record breaking $15 million cash in 1973, then the highest 
price ever paid for a radio station./
