KBUC-FM

On December 31, 1967, the station signed on as KBUC-FM.^[5] Its community of license was Terrell Hills, and it broadcast at 106.3 MHz. The power was only 3,000 watts, a fraction of its current output. KBUC-FM was the FM counterpart to AM daytimer KBUC, so programming could continue to be heard on the FM station after sunset. KBUC-AM-FM simulcasted a country music format, and were owned by Tom E. Turner and the Turner Broadcasting Corporation (which is not related to the current day Turner Broadcasting System).

In 1974, KBUC-FM moved from 106.3 to 107.5 to make way for a new station, KTUF (now KTKX at 106.7 FM).^[6] The move also included a power increase to 100,000 watts and a change in community of license to San Antonio. The new, more-powerful signal allowed KBUC-FM to be heard for many miles around the San Antonio radio market. KBUC-AM-FM continued airing country music and personality DJs, plus news from the ABC Information Network.

Switch to Tejano

In 1986, KBUC-AM-FM were bought by TK Communications. On September 2, 1988, TK changed the FM station's call sign to KZVE, becoming a Spanish-language adult contemporary station known as "K-Suave" ("K-Soft"). In addition, KBUC (AM) became KXTN, airing a Tejano music format.^[7][8]

In 1991, TK decided to swap the formats on the two stations, given that 1310 had significantly higher ratings than the FM counterpart, with 1310 AM becoming Spanish AC as KZVE, while 107.5 FM switched to Tejano. The AC format stayed on AM 1310 until 1997, when it began simulcasting 107.5 FM. In addition, 1310 changed its call letters to KXTN, while 107.5 simply added an "-FM" suffix, becoming KXTN-FM.

In 2003, Univision, which owns scores of radio and TV stations in some of the largest Hispanic media markets, bought KXTN-AM-FM.

Vibe 107.5

On April 12, 2019, at 5:00 p.m., KXTN-FM dropped its longtime Tejano format and flipped to Rhythmic AC with a focus on classic hip-hop, branded as "Vibe 107.5". The first song on "Vibe" was "Return of the Mack" by Mark Morrison. The call sign was changed to KVBH on April 16, 2019. In June 2019, Xavier Castro ("the Freakin' Rican"), former longtime morning host at sister station KBBT, began hosting mornings on the station.^[9]
