XHJC-FM is a radio station in Mexicali, Baja California, Mexico. Broadcasting on 91.5 FM, XHJC carries the Exa FM national format from MVS Radio.

The station's concession was awarded in 1980 to José de Jesús Cortés y Barbosa. The first concept launched was Fórmula Melódica, also known as "Musicali". This lasted a year before the station relaunched with a pop music format under the name Sonido 91.

In the 1990s, the station was sold by Sociedad Mexicana de Radio de Baja California to MVS Radio; XHJC retained pop but adopted Pulsar FM, then a brand shared by MVS and Grupo Imagen. When the two broke up, MVS launched Exa FM in 2000.

The concession was transferred in 2012.
