W) Baltimore, MarylanD's 105.7 WBMD. Sometime around the late 1960s or early 70s, they duplicated the Country music format of sister station AM 750 during the day while flipping to Progressive Rock at night. By 1972 they had gone full-time Rock and changed calls to WKTK.
This sticker was donated to me by a Radio Sticker of the Day visitor. Thanks Paul!
