KIST-FM first signed on in February 1998 as KLDZ-FM with an oldies format[4] branded "Cool Oldies 107.7". It launched as a simulcast of AM sister station KLDZ (1340 AM) before the latter flipped formats to sports.[5]

In May 1998, Citicasters, Inc., part of Jacor Communications, purchased KIST and KLDZ-FM for $1.5 million.[6] The AM station changed its call sign to KXXT and the FM outlet assumed the KIST call letters.[7] In May 1999, Jacor merged with Clear Channel Communications, which would own KIST-FM until 2007.

In March 2000, Cumulus Media-owned KKSB (106.3 FM) in Santa Barbara adopted a contemporary hit radio (CHR) format. In response, Clear Channel flipped KIST-FM to a top 40 outlet branded "KISS 107 FM"; the station featured on-air personality Rick Dees from sister station KIIS-FM in Los Angeles during morning drive.[8][9] Clear Channel won the head-to-head CHR battle with Cumulus as KKSB flipped to oldies within two years.[10] However, on September 8, 2004, KIST-FM changed to a modern rock format with the branding "FM 107.7".[11]

On January 11, 2007, Clear Channel Communications sold all of its radio stations in Santa Barbara, including KIST-FM, to Rincon Broadcasting for $17.3 million.[12][13] Five days later, KIST-FM's format was changed to regional Mexican under the branding of "Radio Bronco".

On December 15, 2009, KIST-FM changed its call letters to KQIE.[7] Two months later, on February 10, 2010, the station reverted to KIST-FM. On July 20, KIST-FM again changed its call letters to KFYZ.[7] That switch was also temporary, as KFYZ restored the KIST-FM call sign on September 10. The KFYZ call letters were transferred to its sister station at 94.5 FM on December 23, 2010 when that station flipped to a top 40 format.
