KHJK (103.7 FM, "103-7 FM") is an Adult Alternative-formatted radio station serving the Houston and Beaumont, Texas, areas. The studios are currently located in the Westchase Bank Building at 9801 Westheimer in Houston, Texas, with its transmitter facility located southeast of Devers, Texas, in Liberty County. The station serves as the only competitor to Clear Channel's rock stations (alternative KTBZ and classic rock KKRW).



KIOL-FM previously operated as KVST "K-Star Country 103.7", which was licensed to service the area north of Houston. Owned by Ben Amato of Conroe (who sold his chain of grocery stores around the Conroe, Texas area to finance the radio station), it originally signed on as KVST in Huntsville, TX on 103.5; however, interference from 103.5 in Buda, TX (Oldies 103.5 Austin, now BOB-FM)caused the station not to reach down to the intended audience of Conroe and a look at a move in frequency was done. It moved to 103.7 and later a simulcast on 99.7 (KUST, Willis) was added to help the coverage in Conroe and The Woodlands. The station, whose signal was poor in comparison to Houston's other country music stations, was purchased by Cumulus Media in mid-2004, which later acquired greater Houston's only Top 40 station, KRBE, in addition to also owning 97.5, the former KAYD-FM (now KFNC and a rimshot for Houston).

In 2005, the station's transmitter was moved to its current location in Devers to service the Houston area. This resulted in another format change, with the station switching to KIOL and its heritage rock format that had been carried on the 97.5 frequency, which was a carry over from the original heritage rock frequency of 101.1 KLOL which had flipped to a Spanish format. 97.5 continued as a simulcast on the latter until switching to a news (and later, ESPN) format.

On August 30, 2007, the Houston Chronicle reported that KIOL would be switching to the Jack FM format at 10:37 a.m. on August 31, 2007 and adopting new call letters, KHJK [1].

In May 2009, KHJK shifted from Adult Hits to Adult Alternative as "103-7FM."
