Try 104 and 106.7, WYAI and WYAY. One of the first single market simulcasts, possible under the Rules of the day because the city grade signals almost, but didn't quite, touch in downtown Atlanta. The T-shirts had "Y106 and 104" on them.
Interestingly, they had the currently longest running morning jock in town, one Warren "Rhubarb" Jones, who's still doing mornings on 106.7. He's closing in on McKee's record for longest in the AM I believe.
