Ummm...not quite.KPRS in Kansas City has been operated by the Carter family since 1949. The Carters bought a partial interest in the station in 1952 and have owned it outright since 1969.
KPRS (KPRT on AM since November 1974) originally was in Olathe, Kansas, now a Kansas City suburb, intended to serve the Johnson County, Kansas suburbs. The Black-owned Twin City Advertising Agency bought the station in 1952 (announced in March, closed in August) and moved the transmitting site to Kansas City that fall, enabling it to go back on the air November 1. The president of the firm was Ed "Cookie" Pate, who was a DJ on Leavenworth, Kansas station KCLO in addition to being president of the advertising agency. Andrew "Skip" Carter was the vice-president. The agency was created a couple of years earlier and began some programming over KCLO (now KKLO) at that time.
When the Carter family bought a controlling interest in the station in June 1969, the Kansas City Star stated that KPRS, by that time both on AM and FM*, was one of four Black-owned radio stations in the U.S.
* KPRS-FM went on the air March 17, 1963.
