The original call letters were KEVE-FM and the station was co-owned with sister AM station KEVE. KEVE's AM history predates the FM by 14 years; it launched in May, 1948 and was owned by Family Broadcasting until mid-1956 and was known until at least then as KEYD, co-owned with KEYD-TV 9 (now KMSP-TV and launched by Family Broadcasting in January, 1955). The KEYD Radio studios were located in downtown Minneapolis on 9th Street off of Hennepin Avenue practically next to the Orpheum Theater (see 1953 photo link below). Calls were changed to KADM to complement its AM sister (as in "Adam and Eve") in October 1963. A gradual shift from country music to a mix of classical music, show tunes and adult standards began in 1960 and was completed on both stations by March 1963. On December 1, 1964, the call letters for both radio stations became KQRS. The KEVE studios had, by 1957, moved to its transmitter site in Golden Valley at 917 Lilac Drive, set back from Minnesota State Highway 100. This location was the first studio and transmitter site for the station.
