XESS-AM (620 kHz) is a radio station broadcasting from a transmitter in Puerto Nuevo, Baja California, Mexico, south of Tijuana.
It is owned by Media Sports de México, S.A. de C.V., and broadcasts a talk format under the banner PSN Radio Tecate, aimed at listeners in Tecate currently off the air.
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.
The next year, it moved frequencies to 620 kHz to reduce interference to stations in the United States and to improve its signal in both Tijuana and San Diego.
