The station at 101.9 FM in Las Vegas signed on in 1963 as KRGN with an easy listening format. It took its call sign from its owner, E. W. Cragin. The Gilday Broadcasting Company bought the station in 1968. In 1974, the station changed its call sign to KFMS and flipped to an automated top 40 format branded "KFM 102". From 1978 to 1980, KFMS was an album-oriented rock outlet. On January 1, 1981, KFMS flipped to a country music format, retaining the KFM 102 name.
Jacor/Clear Channel era (1997-2008)
In 1997, Jacor Communications purchased Regent Communications and its stations, including KFMS, for $184.7 million. Jacor subsequently was purchased by Clear Channel Communications in 1999. On January 7, 2000 at 3 p.m., KFMS flipped to top 40 as "101.9 KISS-FM". KFMS simulcastKIIS-FM in Los Angeles, including Rick Dees' weekday morning program, while Buck Head from WFLZ-FM in Tampa hosted weeknights. The Buck Head Show was later syndicated back to KYSR in Los Angeles until he was eventually transferred to that market. The grouping of KIIS-FM in Los Angeles, KIIS in Santa Clarita, California, KAVS in the Antelope Valley, KYHT in Barstow/Victor Valley, and KFMS in Las Vegas created nearly continuous coverage of KIIS-FM between Los Angeles and Las Vegas. However, KFMS was branded as "KISS" instead of "KIIS". Over time, KFMS began adding more local disc jockeys, including Kate and Rick Kelly from KQOL-FM. After KYHT flipped to hot adult contemporaryin 2001, KFMS discontinued its simulcast of KIIS-FM, adjusted its format to include more hip hop music, and added a local morning show hosted by Trejo and Nikki. The station continued to air the nationally syndicatedRick DeesWeekly Top 40 program. In December 2002, 101.9 Kiss-FM signed off and KFMS began stunting for several days with a loop of "Welcome to the Jungle" by Guns N' Roses. In January 2003, the station debuted a rhythmic contemporary format with the branding "Wild 102" and the slogan "Where Hip Hop Lives"; the call letters changed to KWID. On November 15, 2004, KWID flipped to Mexican oldies as "La Preciosa 101.9".

In May 2008, Lotus Communications acquired KWID in a three-station swap with Clear Channel. In exchange for KZEP-FM in San Antonio, Lotus also received KBKO-FM in Bakersfield, California. The new owner changed KWID to a Spanish adult hits format, branded "La Buena 101.9".
