I remember around 1959 when I was taken to Ormond Beach, FL, for spring break, every radio on the waterfront was tuned to WAPE. That was a good 90 miles from the Big Ape's transmitter on the far west side of its city of license, yet it was an absolute local signal.I seem to recall people saying they listened to this as far north as Myrtle Beach. Although the rocker there was a daytime-only AM. Maybe it wasn't on the air yet.
I believe the Brennans put this on the air in later 1958, the third of their 50 kw daytimers (Birmingham and Montgomery were first). The last was in the Chattanooga market and actually had a night operation.
