History.
The current KSTP-FM began broadcasting in November 1965. It was founded by Hubbard Broadcasting, Inc., which already had extensive broadcasting experience, including sister station KSTP (AM). In 1938 and 1939 KSTP (AM) had also operated a high-fidelity AM Apex "experimental audio broadcasting station", W9XUP, originally on 25,950 kHz and later on 26,150 kHz.
In 1946 an FM station, also with the call sign KSTP-FM, signed on at 102.1 MHz. This first KSTP-FM was shut down in 1952 and the license was cancelled, due to management not believing that FM radio would be profitable. It mostly simulcast the AM station, which was an affiliate of the NBC Red Network, and the stations carried NBC's schedule of dramas, comedies, news and sports. The vacated 102.1 assignment is now home to KEEY-FM.
As more stations added FM counterparts in the 1960s, the current KSTP-FM debuted on November 1, 1965, now on its present-day frequency of 94.5 MHz. This new KSTP-FM also simulcast its AM sister's programming, a full service middle of the road format of popular music, news and sports. In the late 1960s, the FM station began separate programming, airing a beautiful music format. With several other Twin Cities FM stations also devoted to easy listening music, Hubbard would flip KSTP-FM to Adult Contemporary branded as "KS95" in 1975. By 1991, KSTP-FM had evolved into a hot adult contemporary format.
KSTP-FM served as the radio flagship for the Minnesota Vikings football team from 1985 to 1987.
HD Radio.
KSTP-FM began HD radio broadcasting in 2013, and in December of that year added a simulcast of all-sports sister station KSTP 1500 AM on its HD2 subchannel, a simulcast moved from another Hubbard-owned station, KTMY-HD2. The station added an HD3 subchannel, affiliated with the Spanish-language ESPN Deportes Radio in September 2016. The HD3 subchannel was discontinued in September 2019, after ESPN discontinued ESPN Deportes Radio.
