History.
On August 22, 1952, XESS-AM received its concession. The station broadcast to Ensenada on 1450 kHz and was owned by Fernando J. Rodríguez Sullivan. Radiodifusora de Ensenada, S.A. became the concessionaire on March 9, 1966, and in 1986, it raised its power from 250 to 1,000 watts.
In 2003, the station was moved to Puerto Nuevo along with XESDD, and the next year, it moved frequencies to 620 kHz to reduce interference to stations in the United States. Media Sports de México became the concessionaire in 2005.
