In September 1998, Antelope Broadcasting sold its three stations — KAVS, KTPI, and KYHT — to Jacor Communications for $4 million. Jacor would be purchased by Clear Channel Communications the following year. KAVS and KYHT dropped their modern rock programming and began simulcasting the top 40 format of Clear Channel sister station KIIS-FM in Los Angeles. In the early days of Jacor/Clear Channel ownership, KAVS hosted many on-air events in the Antelope Valley and Barstow/Victor Valley areas. The grouping of KIIS-FM in Los Angeles, KIIS in Santa Clarita, 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-FM" instead of "KIIS-FM". Following the Jacor-Clear Channel merger, the new owners made drastic changes that produced a ripple effect across Southern California radio. The KAVS/KYHT simulcast was discontinued, and the latter's operations were transferred to Clear Channel's Victorville office. KYHT continued with the KIIS-FM format for two years, after which it began simulcasting KZXY-FM in Victorville. KFMS in Las Vegas dropped its KIIS-FM simulcast and "KISS-FM" branding, introducing all-local programming and eventually changing formats altogether. Meanwhile, KAVS changed its call sign to KVVS in August 2000. Under Clear Channel ownership, the station gradually reduced its local airstaff and community activity. Eventually, the station dropped all local content except advertisements and simulcast KIIS-FM full-time; the website for KVVS simply redirected to that of KIIS-FM. On December 21, 2007, the KVVS call letters and the simulcast of KIIS-FM were moved to 105.5 FM; that station was previously known as KOSS, "105.5 The Oasis". The KOSS call letters relocated to 97.7 FM, as did the country format from the then-KTPI-FM on 103.1 FM; that frequency then began simulcasting KYSR in Los Angeles. While the format of 97.7 FM was branded as "97-7 KTPI", the KTPI-FM call sign remained at 103.1 FM in Tehachapi temporarily. On January 2, 2008, KOSS and KTPI-FM swapped call signs, with 97.7 FM now becoming KTPI-FM. The station at 103.1 FM took on the KOSS call letters briefly, changing to KSRY on January 10, 2008.
RZ Radio era (2011–present)
As a condition of approving a plan by Clear Channel to become a privately-held corporation, the FCC required the company to divest 194 stations in markets where it exceeded ownership limits by placing them into a trust until they are sold. In January 2008, Clear Channel transferred KTPI-FM and sports radio outlet KAVL to the Aloha Stations Trust. In December 2011, RZ Media LLC, owned by Saul Rosenzweig, purchased KTPI-FM and KAVL from the trust, and KTPI from Clear Channel directly, for a total of $800,000. Weekday programming on KTPI-FM includes Big D and Bubba mornings and Justin Michael in the midday timeslot, which features the "All Request Lunch Hour". Program Director Shannon Smith is on-air during afternoon drive, followed by the syndicated show The Big Time with Whitney Allen Monday—Saturday evenings and CMT After Midnite with Cody Alan overnight. Weekends feature Crook and Chase and Ramblin' Ray.
