@RadioDoogie: WGST was owned by the Georgia University System Board of Regents until it was sold to Meredith in c. 1974. It may have been a CBS affiliate (for some reason, I want to say it was NBC Blue/ABC--WAGA was the CBS affiliate to match the TV station?). Before that it was WCON owned by the Atlanta Constitution (no relation to 99.3 in Cornelia).
WSB's call letters were assigned by the FCC, and it was "backronymed" to "Welcome South, Brother". It was always owned by the Atlanta Journal, as predecessor to Cox. It was the NBC (Red) affiliate for certain (I don't remember for sure who was CBS, who was NBC Blue/ABC, and who was Mutual).
