The entry for WMBL in a booklet from August 1957 to commemorate Morehead City's centennial states: the "radio station is heard from Maine to Florida, and has been heard all the way to Nebraska. Particularly, this is true during hurricane season, when friends and relatives at distant points want information on conditions in this locale."
WMBL was one of the few stations to play beach music in the 1950s and 1960s. A listener of the station noted that an afternoon deejay of that time, Bobbie Dennis, "was bold enough to play records by The Drifters, Clyde McPhatter and Big Joe Turner, to name a few."
