94.7 was definitely WSPO during part of the 70's. Bert Charles, longtime sports announcer and then-owner of WVKO-AM and 94.7, changed the FM calls to WSPO to reflect the fact that it carried live SPOrts, with Charles doing the play-by-play. (Can't recall exactly what team(s)...maybe OSU away games?) Anyway, I recall that its main format was easy listening, and it seemed to play the same 3-hour block of instrumentals over and over. (Mostly garbage musically, except for the fabulous Wes Montgomery...loved his "California Dreamin.") At some point, they started simulcasting VKO-AM at night. I believe that's when the calls changed back to VKO-FM.
