KVOB started as KQNS-FM in September 1988, then located on 95.9 FM with an ERP of 1.3 kW. At the time, the station carried an adult contemporary format. In 1994, B-B Broadcasting bought the station from Smoky Hill Broadcasting, and the following year, the station moved to 95.5 FM and upgraded their power to 15.5 kW. By this time, the station flipped to a mainstream rock format, branded as "Star 95." In 1999, the station flipped back to adult contemporary, keeping the "Star 95" moniker. In 2004, the station began running the "Hits & Favorites" satellite feed from Citadel Media (now Cumulus Media Networks) and changed monikers to "Lite Rock 95.5". A year later, the station switched satellite feeds to Westwood One's AC feed, again keeping the "Lite Rock 95.5" moniker. In 2006, the station rebranded as "OZ 95", again keeping the AC format. In 2007, the station flipped to adult hits, branded as "Bob FM". The station was assigned the KVOB call sign by the Federal Communications Commission on December 1, 2007.A year later, the station switched to Sparknet Communications' national feed of "Jack FM", again retaining the adult hits format.
On December 25, 2012, at Midnight, the station flipped to active rock, branded as "95.5 The Rock." The station now carries the "Rock 2.0" feed from Dial Global. Due to a technical error, the Jack FM feed and the new format were both heard simultaneouslyuntil it was corrected the following day.
The station airs several weekend specialty programs such as the "House of Hair with Dee Snider", and "Racing Rocks with Ricky Rathman". KVOB also broadcasts several local sports teams including Smoky Valley high school, Bethany College, and the Salina Sirens roller derby. It also airs the Nascar Sprint Cup Series via the Motor Racing Network and Performance Racing Network.
