WJMK 104.3 CHICAGO "John Charleston" February 25th 1988 Pt 1 by Jean luc

In early August 1984, the station adopted an oldies format as "Magic 104" and its call sign was changed to WJMK. Dick Biondi was the first disc jockey heard on "Magic 104".Ron Britain was also one of WJMK's original DJs. Initially, "Magic 104" included a few currents in its playlist, but by early 1985, all songs from the current decade were dropped, with the station playing music from the 1950s, 1960s, and early 1970s.
In 1987, the station's transmitter was moved to the Sears Tower, and its ERP was reduced to 4,100 watts.
