KYRV (93.7 FM) is a commercial radio station licensed to Roseville, California, and serving the Sacramento metropolitan area.

KYRV's studios are located in North Sacramento near Arden Fair Mall, and its transmitter is in Granite Bay.

In June 1970, the owners of KPOP (1110 AM), founded by Don Reeves, started a 3,000-watt station on 93.5 MHz in Roseville, California.

Radio consultant Rick Carroll, who developed the format at KROQ-FM in Los Angeles, released it for national syndication in the early 1983; KPOP was one of his clients.

The format included new wave music, synthesizer-based "Europop", and some guitar-based punk rock (such as The Clash and The Ramones).

On January 10, 1986, morning drive time announcers Dave Skyler and Rusty Humphries[2] staged a management-approved stunt to initiate a format change.

They locked themselves in the studio and refused to leave until management allowed them to drop the KPOP call letters and switch the format to album-oriented rock (AOR); the flip occurred six hours later.

[3] In the early 1990s, prime-time disc jockey Kosar Jaff, along with other California DJs, experimented with beatmatching, which had not been done before on primetime radio.

[8][9] Basically, the format was a mix of rock songs released as singles from the 1960s through the 1980s that received airplay on top 40 stations.

The station featured Howard Stern during morning drive and a mix of local and nationally syndicated talk show hosts the rest of the day.

At that point, KXOA continued to air Howard Stern in morning drive and dropped all remaining talk shows from the schedule.

[11] Intending to compete with both KSEG (96.9 FM) and KRXQ, the station added more current material to its music mix in the summer of 2003, but the ratings did not improve.

The move was seen by some as an attempt to pick up the audience KWOD (106.5 FM) abandoned when it shifted to an alternative/triple-A hybrid format on March 18, 2005.

On October 25, 2005, Infinity Broadcasting announced sweeping changes for many of its owned-and-operated stations carrying Howard Stern.

In Sacramento, at 10:30 am, KHWD switched to Jack FM, an adult hits format, with the new call letters KQJK.

The station launched with a full-time DJ lineup with extensive history in the Sacramento market, including KRXQ veterans Dog & Joe in mornings, Monica Lowe from KZZO in middays, Derek Moore from KSEG in afternoons, and the syndicated Sixx Sense with Nikki Sixx in evenings.
