KMVK

On February 18, 1965, 107.5 signed on the air as KNOK-FM, an R&B and Soul music station.[2] It simulcast its sister station KNOK AM 970 (now KHVN), with both stations owned by the Chatham Corporation. The station was later sold to Black Enterprise magazine founder Earl G. Graves Sr. under the company name EGG Dallas Broadcasting Inc. (EGG are Graves' initials). KNOK-FM originally broadcast with 100,000 watts but from a tower only 450 feet in height above average terrain. (Today KMVK broadcasts from a tower at 1884 feet HAAT but it reduced its power over the years to 17,000 watts.) In 1985, the station became KDLZ while retaining its R&B format. The coverage area was increased and the studios were moved to Cedar Hill after the original studios in Fort Worth were destroyed by fire.[3]

Smooth Jazz 107.5 The Oasis ident used from 1992 to 2003.

In December 1988, Gilmore Broadcasting purchased KDLZ. On December 23, Gilmore picked up the easy listening format and KMEZ call letters from 100.3 (now KJKK) to 107.5.[4] The station was then sold to Granum Communications in 1991. On July 4 of that year, Granum flipped the station and format to KCDU ("CD 107.5") with a short-lived classic rock format.[5] A Smooth Jazz format began on November 2, 1992, moving over from 106.1 (now KHKS). The Smooth Jazz station took the call letters KOAI as "The Oasis." (The KMEZ call letters are now assigned to a New Orleans station, which airs an Urban Adult Contemporary format).[6] In 1996, KOAI was one of three radio stations that fell victim to the radio tower collapse in Cedar Hill on October 12 of that year. KOAI, as well as sister stations KRBV (now KJKK) and KYNG (now KRLD-FM), scrambled to get their stations back on the air through an auxiliary tower. "The Oasis"' ratings seemed to escape unscathed in the Fall ratings book that year, but the fate was not as good at the other 2 stations.[7]

Movin 107.5 logo used 2006–2009.

"107.5 The Oasis" remained on air until October 2, 2006, at 5 p.m., when KOAI flipped to Rhythmic Adult Contemporary as "Movin' 107.5." [8] The Oasis then moved to 107.5 HD-2 (and today is on an HD channel of KVIL). The station's logo and branding was identical to MOViN radio station KVMX (now KXJM) in Portland, Oregon (then owned by CBS Radio, but is now owned by iHeartMedia). The initial format change to "Movin'" caused a lot of criticism by listeners of "The Oasis", many of them demanded that the smooth jazz format be reinstated on the traditional signal.

On February 17, 2009, at Noon, after playing "Vogue" by Madonna, the station flipped to a Spanish Hot adult contemporary format as "Mega 107.5."[9] In 2010, "Mega 107.5" shifted to a Spanish rhythmic contemporary playlist (similar to its MOViN predecessor) with a few English-language hits in between.[10] It was competing head-on with KESS-FM (La Kalle 107.9) for over 2 years, until that station's owner, Univision Radio, switched it to a simulcast of KDXX, leaving KMVK the only Latin Pop-formatted station in the Metroplex for a short time. In late June 2012, it gained another competitor from Univision Radio with KDXX.

By mid-summer 2012, the Metroplex had three Spanish-language CHR stations and three English-language CHR outlets, with one of those English-language stations targeted towards Latino listeners. The former "La Kalle 107.9" from Univision Radio changed KESS (now KFZO) to "Radio H2O" in late June 2012. KTCY Baila 101.7 (previously owned by Liberman, now owned by EMF) was one of its short-term competitors until February 8, 2013, when the station's format was changed.

On March 8, 2012, the station's website displayed a message stating "Todo va a cambiar!" (Translation: Everything will change!), hinting at a possible format flip in the near future. However the next morning, it was nothing more than a Daylight saving time announcement.[11]

On May 21, 2012, CBS hinted at a possible format flip on either KMVK or KRLD-FM to "AMP Radio", much like its Los Angeles CHR/Top 40 sister station KAMP-FM. The parent company registered 3 web domains (as AMPRadioDFW.com, AMPRadio1053.com, and 1075AMPRadio.com).[12] This format change instead happened four years later in 2016, when sister KVIL evolved to Top 40, which flipped to Alternative the following year.

On July 26, 2013, KMVK did flip formats, though to a Regional Mexican format as "La Grande 107.5",[13] making it the 3rd format flip since 2006. The Latin Pop format is now heard on an HD Radio subchannel on 107.5.

On February 2, 2017, CBS Radio announced it would merge with Entercom.[14] The merger was approved on November 9, 2017, and was consummated on the 17th.[15][16]

Months after, Entercom struck a new content deal with NBCUniversal-owned-and-operated stations KXAS-TV (NBC) and KXTX-TV (Telemundo). The latter will partner with this station to bring enhanced Spanish-language news, weather and entertainment information to its listeners, in addition to the current Regional Mexican music format.[17]
