There was an article posted on our Knoxville Radio History 101 Facebook page about WROL from the late 40's.
Don't you love the control room photos! This is Allen Stout, listed as a WROL announcer. Also on staff were Ron Ashburn and Harry Moreland.
At that time WROL was 5000 watts at 620 KC and 76000 watts on WROL-FM 97.3. The tag line was "NBC for East Tennessee".
