Monroe County Broadcasting Co., LTD. formed a corporation in 1968 to compete for the available FM frequency 103.9 in Monroe County, New York. WDKX commenced broadcasting on April 6, 1974 at 5:30 AM and has been broadcasting 24 hours a day, seven days a week ever since. WDKX has been under the same ownership since its inception. Andrew A. Langston, founder and former owner and general manager of WDKX, received the "Rochester Radio Broadcaster of the Year" Award, the National Association of Black Owned Broadcasters "Pioneer" Award, and was inducted to the "New York State Broadcasters Hall of Fame" inaugural class.
Keeping with its Urban Contemporary format, WDKX chose its call letters to honor Black heroes ("D" for Frederick Douglass, "K" for Martin Luther King Jr., and "X" for Malcolm X).
