KWFS-FM (102.3 MHz branded as "102.3 The Bull") is a radio station serving the Wichita Falls area with a modern country format.

KNTO-FM, the first FM station in the Wichita Falls area, went on air in August 1961, owned by a partnership of five local businessmen including Bob Lipscomb, Bill Thacker, and three others, and the station's callsign stood for "North Texas and Oklahoma".. KNTO operated from the Onaway Trail tower, still used today, on 95.1 MHz with 3,100 watts horizontal only at 430 feet above average terrain.

There was some income from Muzak brand background music played on the station's SCA channel.

The KNTO call letters stayed but the logo was modified to include a peace symbol.

Local DJs during the hard rock era for the station included Bill Daniels.

The station filed for and received a grant to move to 103.3 MHz with 100,000 watts horizontal and vertical at 450 feet.

The station changed channels in 1998 to 102.3 as part of a frequency shuffle that put 103.3 on-air as a rimshotter of Dallas-Fort Worth.
