WBRC-FM were the calls way back then, of course, and actually it was a little more than 500kW. But you're right about the 200-mile coverage, or so they claimed. Scroll to the last item on this page from Jeff Miller's great site, "History Of American Broadcasting": http://jeff560.tripod.com/fm-max.html
Considering the number of FM radios 60 years ago, that was Wasted 500+kW! (We now return to the discussion about 50kW AM's, already in progress...)
