KRMP first signed on the air as KLPR. The station went through various formats such as Country and Disco. The call letters later flipped to KATT and started simulcasting Rock with its former sister stationKATT-FM 100.5. In the Capitol Hill High School in the 1953-1954 yearbooks they sponsor the station. In the Spring of 1986, the station dropped simulcasting with KATT-FM and flipped to Urban Contemporary as KPRW "Power 1140". This move came when former Black/Urban station KAEZ-107.7 went off the air in the Fall of 1985. KPRW had great success with its Urban format, it even scored a 7 share in the ratings making it one of the Top 10 stations in Oklahoma City despite the station being a daytimer. By late 1989 and the early part of 1990, KPRW started losing some of its audience to Top 40 stations KJYO "KJ-103" and KZBS "Z-99" which were both leaning heavily Dance and Rhythmic at the time. By the latter part of the early 1990s KJYO and KZBS both started changing directions in their formats. KJYO went back to a Mainstream Top 40 direction and KZBS started leaning towards an Adult Top 40 direction, eventually becoming Hot ACKYIS "98.9 Kiss-FM", but it was too late for KPRW to regain its audience. Around that time KPRW dropped its Urban format and became a Business News/Talk format as "Power Business News 1140" once again leaving Oklahoma City without an Urban station. The format lasted for about 2 years when it was dropped and KPRW started simulcasting Rock with KATT-FM again. In 1993, Oklahoma City businessman Russell Perry, founder of the weekly newspaper The Black Chronicle purchased KPRW and changed the format back to Urban as KVSP "Power Jammin' 1140" filling the void as the Urban station in Oklahoma City, since the market had been without such a station since the early 1990s. The station once again had success by becoming the Top 10 station in Oklahoma City. KVSP was faced with competition in 2000, when new Rhythmic Top 40KKWD "Wild 97dot9" signed on the air leaning heavily towards Hip-Hop & R&B with a mix of Dance and some Pop, this hurt KVSP a little bit. By this time the station signed an agreement with Clear Channel to purchase airtime on KEBC-1340 and broadcast KVSP's Urban format from 7pm-7am right after KVSP signed off at sunset on AM 1140 calling it "The Power Jammin' Network". In 2004, Perry Broadcasting purchased Country station KRPT-103.5 in Anadarko, Oklahoma, the signal was upgraded to target Oklahoma City. The KVSP call letters and Urban format were moved to the FM dial and it became "Power 103.5" targeting a younger audience with its format. That same year AM 1140 changed to its current format Urban Adult Contemporary as KRMP "The Touch 1140". KRMP also airs Talk and Infomercials in certain dayparts with addition to music. It also airs Tom Joyner in the morning and previously aired Michael Baisden in the afternoon until his cancellation at the end of March 2013 and replaced the show with local talent in the afternoons. In 2012, KRMP relaunched the station as "Heart & Soul 92.1 and 1140" with the addition of translator K221FQ on 92.1, allowing the station to broadcast 24 hours on FM once AM 1140 signs off at sunset.
