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.

XHLNC, which for its first six months was known as XHTNA-FM, was originally permitted to sign-on with a Class A 1,000-watt signal, broadcasting from a tower located in the Mount San Antonio area of Tijuana that had been used by other Califórmula stations.

Due to KPFK's enlarged coverage area, XLNC1's signal suffered co-channel interference in many sections of San Diego County.

On June 29, 2007, Cofetel, 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 decision was also made to remove lengthy repertoire and opera from general programming in favor of lighter classical and crossover works.

As a classical station serving a binational audience, XLNC1 typically introduced pieces in Spanish and gave the information in English at the end.

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).

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.
