KCSP (610 kHz) is a commercial AM radio station licensed to Kansas City, Missouri. The Audacy, Inc.-owned station broadcasts a sports radio format. The studios and offices are located on Squibb Road in Mission, Kansas. KCSP is one of the oldest radio stations in the Kansas City metropolitan area, going on the air in 1922, just after KMBZ, and several months before WHB. KCSP is a Class B regional station, with a power of 5,000 watts, both the daytime and nighttime, using a non-directional antenna on one tower. The transmitter is off Mission Road in Prairie Village, Kansas. Programming is also heard on the HD2 channel of WDAF-FM. Local sports shows are heard from mornings to early evenings on weekdays, with programming from Fox Sports Radio airing nights and weekends. Although the station had the slogan "The Football Channel" when it began in June 2003, it is currently the flagship station of MLB's Kansas City Royals, whose rights were reacquired by Entercom (now Audacy) in 2008. The parent company held the rights to the Royals on co-owned KMBZ until 2003. The Kansas State Wildcats radio network is also heard on KCSP. History Early years (1922-1967) On February 19, 1922, the Kansas City Star signed on experimental station 9XAB, licensed at 833 kHz, at a time when other newspapers in town were also putting radio stations on the air. Popular Science magazine noted the station in its March 1922 issue for airing weather and market reports at 11:30 a.m. and 2:00 p.m., and concerts in the evening. The station took the call sign WDAF on May 16, 1922. In the early days of radio, the dividing line between stations holding call letters beginning with a "W" and those with a "K" was the western border of Kansas, which is why its original call sign began with a "W." WDAF bounced around various frequencies, including 750, 730, 680, 820 and 810 kHz. It moved to 610 kHz in 1928, splitting time with station WOQ, before becoming the sole occupant of 610 AM in Kansas City. WDAF became an NBC Radio affiliate just before moving to 610 kHz. It carried programs from both the NBC Red Network and the Blue Network up until 1930, when WDAF became a primary NBC Red affiliate. WDAF increased power to 5,000 watts daytime in 1935, and 5,000 watts nighttime in 1940. In 1949, WDAF signed on WDAF-TV
