KFSP

Plans for the station began as early as 1935, with a deposition hearing ordered by the Federal Communications Commission. The station first signed on the air in 1938 under the call sign KYSM. It was constructed by the F.B. Clements Company, featured two studios, and utilized a 281-foot radiator tower. KYSM initially broadcast from 6 a.m. to 1 a.m. with 250 watts of daytime power and 100 watts at night. KYSM began as an NBC AM-radio affiliate but later switched to the Mutual Broadcasting System in 1983. KYSM was a Top 40 station in the 1960s, full service MOR station during the 1970s and 1980s. The station aired a satellite-fed oldies format until 1995, when it flipped to a satellite-fed adult standards format. ==Programming==

The station broadcasts games for local and regional teams, including Minnesota Vikings Football, Minnesota State University-Mankato Football and Basketball, and Mankato MoonDogs Baseball. They also cover Mankato Loyola Crusader Sports. To improve the signal strength and coverage area in Mankato, the station's FM translator, K276EH (103.1 MHz), completed a significant move to an antenna higher on its existing tower in May 2024. This technical upgrade helps the AM signal reach listeners more clearly through the FM dial. ==References==
