KDWB-FM (101.3 MHz) is an American commercial radio station broadcasting in the Twin Cities region of Minnesota, licensed to suburban Richfield. KDWB's radio format is Top 40/CHR. Its transmitter is located in Shoreview, while its studios are in St. Louis Park. The station is owned by iHeartMedia. History Between its AM and FM frequencies, KDWB has been an uninterrupted Top 40 outlet since 1959. Originally starting out at 630 kHz, the station's owners (Doubleday Broadcasting of Garden City, New York) purchased the 101.3 MHz frequency in 1976, later transferring the entire format there. 63 KDWB KDWB's origins on the AM dial date back to 1951, at 1590kHz. The station began as a collaboration between three brothers who named it WCOW, and it played country western and old-time music. In the early days, WCOW, which was licensed to South St. Paul (its original city of license), signed on with a cowbell. The studios, transmitter, broadcast towers and offices were located at 255 Radio Drive South in Woodbury. In 1949, the three brothers, Al, Vic, and Nick Tedesco applied to the Federal Communications Commission for the purchase of WSHB in Stillwater. The application was approved, on March 15th, 1949; WAVN in Stillwater signed on the air as a 5,000 watt non-directional Day-Timer with 500-watt pre-sunrise authority. The Tedesco brothers attempted to get into television on channel 17 the next year, but financial backing fell through. (The channel 17 allocation was taken by Twin Cities Public Television in 1965.) Since the initial purchase of WAVN in 1949, the Tedesco brothers acquired and/or sold several other radio stations, spanning over 50 years, sometimes with partners. On April 18, 1994, after 36 years, the 630kHz frequency went dark. The owners, Midcontinent Media, sold the property, and the state of the art facilities were dismantled, salvaged and/or destroyed to make room for the construction of the-then State Farm Insurance Companies regional headquarters. WCOW was not very successful, so the station transitioned to being a female-oriented station including commercials aimed at its target audience, with a heavy saturation of long term ad contract, with the call letters changing to WISK in 1957, and switched its frequency to 630kHz the next year. Again, the format was not popular, and the station was sold the following year to Crowell-Collier Broadcasting Company, owners of KFWB in Los Angeles and KEWB in San Francisco.
