KHJK (103.7 FM, "Air 1") is a Christian rock-formatted radio station serving the Houston and Beaumont, Texas, areas. It relays the satellite delivered Air 1 format by owner Educational Media Foundation.

KHJK rebroadcasts its programming on 95.3 K237FS in Conroe. This enables KHJK to have a city grade signal in Conroe, which the main 103.7 facility can not provide to listeners.

KHJK-FM previously operated as KVST, "K-Star Country 103.7", which was licensed to service Montgomery County, Texas, prior to being purchased by Cumulus Media in 2005.

Originally owned by Ben Amato of Conroe (who sold his chain of grocery stores around that area to finance the radio station), it signed on as KVST in Huntsville on 103.5; however, interference from KEYI (now KBPA) in Austin caused the station not to reach down to the intended audience of Conroe and a look at a move-in frequency was done. Amato moved the station's frequency up one channel to 103.7, and also physically moved the tower site south to Willis.

This resulted in an excellent signal in Conroe, Willis, and the exploding community of The Woodlands. However, the signal was all but lost in Huntsville, which was solved by Amato bringing a new station to life, licensed to Huntsville, in order to simulcast KVST. That station became KUST at 99.7 MHz.

Ironically, in 2005, Cumulus Media purchased the license for 103.7, and once KVST relocated to La Porte, 99.7 made the same journey down Interstate 45 that 103.7 had made in the years before it ultimately moved to the Devers tower, east of Houston.

Since then, 99.7 KVST has reversed the move and returned to Huntsville, transmitting from the original 103.5 tower.

As a part of the move of 103.7, KUST switched call letters with KVST, resulting in the new 99.7 in Willis becoming KVST, while the KUST calls were shipped to this facility. These calls were short lived as they were only used for the "TV 103" stunt format utilized while Cumulus prepared for the move of 97.5 KIOL's rock format and call letters to the debuting 103.7 signal in Houston and The Golden Triangle. KBIU in Lake Charles was also affected by the move of this facility as it also operated on the 103.7 frequency. This was resolved by Cumulus downgrading KBIU, which the company also owned, and also moving its operating frequency to 103.3.
