I helped put that station on the air, back in about 1976, when it was part of the WPTX pair.
Rocky Willis was the manager, Carey Corson and a guy named George were the engineers, Clarence Beverage (nephew of THE Harold Beverage, of antenna fame) was the consultant.
We had "Sunshine Sonny Stephens", "E.K. Bromley", John Griffiths, and a few others as air talent. Not sure how many of those were on air with WMDM.
Some of the construction was a "comedy of errors", as we had to replace the BE audio board with an RCA, since the AM (920 KHz) RF was killing the less-shielded BE. Trouble was, the RCA board was deeper than the desk top, so it hung out over the edge.
Had to remove and replace the tower after they tried to hang the FM antenna, since it wouldn't support the weight. That's why the tower closest to the building is a fatter one.
Those were fun days. Anyone heard from "Rockin' Ray" lately?
