History.
WEBC-FM began broadcasting on March 15, 1940, as what was then "the farthest west United States FM radio station", and with the experimental callsign W9XYH. It was an early adopter of United States low band (44-50 MHz) frequency modulation broadcasting. When the FM band was moved to its present location of 88-108 MHz in 1945, WEBC-FM (then WDUL) was the first station in the nation to begin regular programming on the new band.
