WEBC-FM (92.3 FM) was a radio station licensed to Superior, Wisconsin and which served the Duluth-Superior metropolitan area.
WEBC-FM began broadcasting on March 15, 1940, as what was then "the farthest west United States FM radio station",[5] 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.
