Zach: When I worked for WABG they were "Blocked"....different formats based on dayparts and day of week...gravitated mainly to "MOR", IE adults standards of the day. It was one of the earliest Bahakel
stations, and was located near the main river bridge, near downtown. It was directional nights, the first such station I worked for. The first station in town was WGRM, followed by WABG, then WLEF (now WKXG) put on the air by a local businessman...that enjoyed lukewarm success...then WSWG, Now MAX 99, the first FM in town. (I may have the last two out of order...we are talking about a LONG time ago.) Then, lastly, WGRM FM.
By the way, to the best of my knowledge, WSWG was the first FM stereo station in Mississippi, and their original installation was top of the line RCA equipment and was VERY impressive!
