KFZO (107.9 FM), is a Regional Mexican station serving the Dallas/Fort Worth metroplex in Texas. The station is licensed in Lewisville, Texas, and owned and operated by Univision Radio. The station's studios are located along the John W. Carpenter Freeway in the Stemmons Corridor of Northwest Dallas.

The KESS call letters were first used in D/FW in the spring of 1976 when Marcos Rodriguez, Sr. father of Marcos A. Rodriguez gained control of a country station, KBUY-FM, on 93.9 FM. That station changed to 94.1 when it moved its transmitter to Cedar Hill, TX in order to avoid a spacing problem with another Dallas station.


Early beginnings

The current version of 107.9 was made possible when Marcos A. Rodriguez successfully obtained a new class C2 licensed to Gainesville, Texas, and purchased 107.9, a Class C licensed to Corsicana, Texas. After Rodriguez sold to Heftel Broadcasting and Mac Tichenor gained control of HBC, Tichenor moved the Corsicana signal south to the Waco market (as the new class A6 in Robinson, TX called KHCK-FM) and allowed the Gainesville signal to upgrade and move into Dallas as a class C1 in Lewisville, TX. The upgrade project had been started under the Cecil Heftel version of HBC, and completed by the engineers at Tichenor Media/HBC working under David Stewart (now owner of radio station in Texas and head of upgrade consultancy Moving Target Consulting Works). The call letters changed a few times through KDXX and KESS-FM.

107.9 La Kalle

On February 19, 2009, the Regional Mexican station branded as "La Que Buena" was moved from KESS-FM to 107.1 FM (KDXX) and 99.1 FM (KFZO). The reggaeton-formatted station and the "La Kalle" (Spanish for "The Street") branding were then moved to KESS-FM and shortly after, the format was retooled to Latin Pop.

KESS HD Programming

In late 2011, the "La Kalle" format has been dissolved and replaced with a simulcast of its sister station KDXX, reducing the number of formats by one in DFW's market. KESS-FM was broadcasting in HD Radio with its HD2 subchannel simulcasting San Antonio-based sister station KXTN-FM with a Tejano format (labeled as "Tejano HD Dallas"). In the months following the format change, the HD broadcasts have been temporarily discontinued. However, they have been restored in the beginning of 2012. It was in competition with CBS Radio's Spanish Rhythmic AC station KMVK Mega 107.5 prior to the recent format change.[2]

Top 40/Rhythmic era

On June 28, 2012, KESS flipped to Bilingual Top 40/CHR, billing themselves as "Radio H2O" (H2O: Hispanic 2.0) with a mostly English-language presentation with some Spanish Pop hits, targeting bilingual and younger Hispanics.[3] The last song of the Recuerdo format was "El Sol No Regresa" by La 5ª Estación with the first song of the H20 station being "Hotel Room Service" by Pitbull. The station initially ran jockless. However, new DJ Stephanie Marie handled the midday drive from 10AM to 3PM. Texas-based Pop singer Austin Mahone became a guest DJ on October 22. DJ AK handles the club mix program at 5 and 9PM weeknights. The station did not hire any more DJs during this time. The H2O format competed head-on with Clear Channel-owned KHKS 106.1 Kiss FM & Cumulus Media's KLIF-FM i93.3, and shared audience with CBS-owned station KMVK Mega 107.5 (Latin Pop). In November 2012, "Radio H20" leaned more of a rhythmic direction. Liberman-owned KTCY Baila 101.7 was one of its competitors until February 8, 2013, when Educational Media Foundation took over ownership and preparing to launch satellite-fed Christian Rock format Air1.

On May 9, 2013, Univision announced that KESS would rebrand to "Hot 107.9" as it shifts directions to a more conventional Rhythmic Top 40 presentation, in part due to an increase in the ratings since phasing out the Spanish music and content.[4] On May 17, at Noon, the station officially rebranded as "Hot 107.9" and made the evolution to a Rhythmic direction, putting it in line with sister stations KBBT/San Antonio and KKSS/Albuquerque.

107.9 today

On July 29, 2013, Univision pulled the plug on KESS' Rhythmic format after 2 months without a word of a format change announcement, making it not only the shortest-ran rhythmic station in the metroplex, but one of the shortest-ran format periods not only for the Rhythmic format, but for radio altogether, and leaving said metro area without such a format once again. It is replaced by KFZO's Regional Mexican format after KFZO (now KESS-FM) became a simulcast of sister station Spanish Top 40 sister KDXX. The shuffling was done in response to KMVK's shift from Spanish Contemporary to Regional Mexican and to protect KLNO, whom KMVK will be competing against.[5] The Rhythmic CHR format continued on this station's HD2 subchannel (replacing KXTN's simulcast), their official website through audio streaming and through iHeartRadio for over 2 weeks[6][7] until Wednesday August 14 when "Hot 107.9 HD2" was replaced with a simulcast of KDXX/KESS

On August 9, 2013 KESS-FM swapped their call letters with KFZO.

Sometime in early 2014, KFZO (alongside other Univision-owned stations) has dropped their "La Jefa" branding in favor of using its frequency as its ident.
