The KHKK license has its roots in KTRB-FM, the sister station to KTRB radio. The station went on the air in 1948, and simulcasted its sister AM station. By late 1970, KTRB-FM was programming a combination of AM simulcast, and night time Progressive Rock programming. In May 1973, the station was sold to Pappas Broadcasting, along with its AM sister station. At that time KTRB-FM, relaunched as KHOP. KHOP programmed a combination of simulcast of sister station KTRB (overnight hours and early mornings), brokered religious block programming (early mornings through late afternoons), ethnic block programming (late afternoons through 10:00PM) and late night Jazz (10:00PM-Midnight) from May 1973 through March 1978. In March 1978, KHOP re-launched as an automated, tightly-formatted Album Rock format and identified as "Rock 104." In November 1979, KHOP gradually moved to a live Top 40 format and evolved to full-on CHR as "Stereo 104." The format remained in effect until November 2, 1992. It switched to Album Oriented Rock on November 2, 1992 and was known as Rock 104.

On April 23, 1996, Rock 104 moved to its new frequency at 95.1 FM, and after a few days of an all-Elvis stunt, it switched formats on April 29, 1996 to classic hits and changed its call sign to KROW, Arrow 104.1 "All Rock & Roll Oldies".

On August 5, 1996, KROW became KHKK "The Hawk", retaining the classic hits format. On December 1, 2000, The Hawk moved to a harder-edged classic rock format, while The Bob & Tom Show moved over from its sister station at 95.1 FM. Richard Perry is the Hawk's Program Director, and serves as disc jockey from 9 a.m. to 2 p.m. He was formerly employed at the legendary, original KDJK (at 95.1 FM) as production director as well as co-host with Beaver Brown on the morning show.

KDJK simulcasts this station on FM frequency 103.9 MHz, serving Mariposa, California.
