KHYZ (99.7 FM) is a radio station, licensed to Mountain Pass, California. It broadcasts a dance radio format branded as Vibe 99.7. The station is owned by Richard Heftel's Heftel Broadcasting Company, with studios in Las Vegas, Nevada.

The station originally launched in 1980 as KXVR, as part of a simulcast with KRXV in Yermo that sought to provide coverage along the Mojave Desert corridor of Interstate 15. The stations' format would primarily target drivers traveling to Las Vegas and Laughlin, Nevada from California, with a mix of music and travelers' information, and advertising for resorts, events, and attractions. Morning programming would target Barstow instead.

In June 1992, KXVR changed its call letters to KHYZ. In June 2002, KHYZ moved from 99.5 FM to 99.7 FM, and decreased in power to 8,400 watts.

In June 2009, KHYZ added a booster signal in Las Vegas to improve its coverage in the city itself. KHYZ later relocated its main transmitter and increased the power to 50,000 Watts.

On October 5, 2023, KHYZ broke away from the Highway Vibe trimulcast (which by then was carrying an hot adult contemporary format), and flipped to dance radio as Vibe 99.7. The new format is programmed by the former staff of KGHD-LD Acid 87.7 (which concurrently relaunched its own dance format with new management). KRXV and KHWY continue to air on 99.7 via an HD Radio subchannel
