XEMO-AM (860 AM, La Poderosa 860 AM), is a Spanish-language radio station that is based in Tijuana, but the signal can be heard as far away as Los Angeles.

XEMO is operated by San Diego–based Uniradio, Inc., with the concession and transmitter owned by a Mexican company.

XEMO is the Spanish flagship radio station of the San Diego Padres.

In 1960, the station was knocked off the air by a fire, started when a transmitter short circuited and ignited a rug, that caused $50,000 in damage.

In turn, Faist transferred the station to Gustavo E. Astiazarán Rosas in 1969.
