On October 1, 1969, the station first signed on.[4] It was locally owned by Harry Hoth's Pikes Peak Broadcasting Company under the call sign KRDO-FM. It was the sister station to KRDO, which Hoth had first put on the air in 1947, Colorado Springs' second radio station. KRDO-FM broadcast a beautiful music format of instrumental songs, and would later shift to easy listening.
As the easy listening format began to decline due to older demographics, KRDO-FM flipped to a soft adult contemporary format and adopted the moniker "Peak 95.1" in 1994. In 1998, KRDO-FM evolved into hot AC.
After being purchased by Citadel Broadcasting, the station prepared for a major format switch. "Cat Country 95.1" began broadcasting on July 1, 2006, stunting by repeatedly playing Brooks & Dunn's "Play Something Country". After several days of stunting, the station began its regular mainstream country programming, featuring a complete air staff. As part of the flip, the longtime KRDO-FM call letters would be changed to KATC-FM. Citadel would revive the "Peak" moniker and AC format in late 2006 on sister station 92.9 FM, under new call letters KKPK. The KRDO-FM call sign was quickly picked up by the News-Press & Gazette Company, to pair with its previous partners, KRDO and KRDO-TV. (The current incarnation of KRDO-FM broadcasts on 105.5 FM.)
Citadel merged with Cumulus Media on September 16, 2011.[5] On October 31, 2014, KATC rebranded as "Nash FM 95.1". The Nash FM moniker is used on numerous Cumulus country stations around the U.S. KATC returned to the “Cat Country” moniker on April 8, 2020.[6]
