History
As a classical music station
Foundation and early years
The station was founded by Víctor Díaz, who owned Califórmula Broadcasting, a company that controlled numerous stations in Tijuana. Upon his death in 2004, Diaz stipulated that XHLNC-FM continue with its classical format, from funding Díaz had set aside, as well as contributions from listeners. The station permit was transferred to Martha Margarita Barba de la Torre, his wife.
XLNC1 began in 1998 as an

. However, due to a treaty between the US and Mexico concerning radio stations near the border, XLNC1 could not increase its coverage much north of the border. Despite this, Díaz solicited a power increase for XHLNC to 10 kW, which the SCT approved on July 14, 2003.

, the Mexican Federal Telecommunications Commission, cleared XHLNC-FM to switch frequencies to 104.9 MHz and move its transmitter to Cerro Bola in Tecate (also used by
XHHIT-FM and
XHPRS-FM). The move was announced by XLNC1 the next month. The switch would bring less interference to the station, resolve interference to KPFK, allow the station to boost its power from 1,000 watts to 7,500 watts, and move its tower to "the highest point in Baja", above sea level.
Transmitter problems
The frequency change took place on February 10, 2008. At first, the 90.7 frequency aired a pre-recorded message by Gordon Brown stating that XLNC1 had moved to 104.9 FM. Unfortunately, the new transmitter had problems, causing some listeners to experience reception problems on XLNC1's new frequency. About two weeks after the frequency change, XLNC1's e-mail newsletter reported that there was a faulty component in the transmitter that would take some time to replace. On February 26, XLNC1 decided to

programming on both 90.7 and 104.9 frequencies. By fall of that year, XLNC1 had its 90.7 frequency taken back by the Mexican government, and the station was broadcasting only on 104.9 FM.
In 2010,
XHTIM-FM was authorized to move from 97.7 to 90.7 and increase its power by using the frequency on which XHLNC once broadcast.
Moving away from longer works

In July 2010, XLNC1 decided to remove the label "Classical Music" from its advertising and replace it with more generic terms such as "Great Music", "Beautiful Music", and "Music for All Generations." The decision was also made to remove lengthy repertoire and opera from general programming in favor of lighter classical and

The end of classical and Toño era
On February 9, 2018, XLNC1 announced through their official Facebook account that they would no longer be broadcasting on FM and would only continue online, effective March 1, due to a lack of continued donations.
The announcement read:
"Dear listeners, it is with a heavy heart that we inform you that as of March 1, XLNC1 will no longer be broadcasting on the air (104.9 FM). We will, however, maintain our streaming service online via our website at www.xlnc1.org, and you will still be able to listen to us through our App on iPhone and Android devices. We are truly grateful for all the years we have been able to reach our wonderful audience in San Diego and Baja California, and we sincerely thank you for all of your generous support through the years."
The station ended FM transmissions on March 2, and on March 3, the new format was announced: the 104.9 frequency was taken over by Grupo Larsa Comunicaciones, the largest broadcaster in Sonora which had assumed control of stations in

On December 17, 2019, MLC Media, a Spanish-language radio syndication company based in Los Angeles, announced it would assume control of XHLNC and run it as Spanish rhythmic "Más Flo" beginning the next day, with programming originating from its LA studios.
On April 1, 2020, MLC Media pulled the plug on the "Mas Flo" Spanish rhythmic format and changed their format to Spanish adult hits, citing the noncommercial nature of the XHLNC concession.
The station then returned to Spanish adult contemporary/adult hits as "Click XM".
In March 2021, new operators took control of XHLNC-FM, and the station flipped to
