XEQJ-AM 1550 received its concession on February 13, 1967. Owned by María del Carmen Pelayo de Pérez, it was a 500-watt daytimer. The current concessionaire took control in 1972. It soon moved to 1560 kHz in order to increase power to 5 kW, and it moved again, to 840 kHz, in the 1990s.
It was bought by Promomedios Jalisco in 1985 and approved to migrate to FM in 2011.
