[4] Rivas Marentes, doing business as Radio Moderna Mexicana, S.A., obtained the concession—now for 92.5 FM—on January 19, 1972; while other concessions had been issued earlier, XHRM is recognized as Baja California's first FM station.

In January 1988, the Tijuana transmitter was toppled in a storm; it took nine months to build a new permanent tower, during which time XHRM's power was drastically cut and the station lost its national advertising accounts.

The programmers ceased to pay their monthly fees in a last-ditch effort to get Radio Moderna Mexicana to bail them out.

XHRM later suffered a tragic setback when Rivas Marentes, the founding owner, died in a plane crash near Hermosillo that September.

By late 2009, a San Diego company, Finest City Broadcasting, was the programming operator of not only XHRM, but also two other Mexican-licensed stations, XHITZ and XETRA-FM.

In January 2010, Local Media of America acquired most of the assets of Finest City Broadcasting, including these programming rights.

[13] On October 6, 2015, Midwest Television (owners of KFMB and KFMB-FM) announced that it had entered into a joint operating agreement with Local Media San Diego LLC, forming an entity known as SDLocal to manage their collective cluster of stations.

The intent of this agreement is to "[preserve the] local ownership and operation of San Diego's top-rated radio stations".
