XEPRS-AM, known as The Mighty 1090 (formerly XX Sports Radio), is an American-operated sports talk radio station targeting English-speaking listeners in San Diego. Its signal originates from Rosarito, Baja California, Mexico, and it broadcasts in English out of studios in San Diego. XEPRS was the flagship station of the San Diego Padres from 2004-2016,San Diego Toreros men's basketball, San Diego State Aztecs football and basketball, and the San Diego Gulls. The station also used to air games for the Anaheim Ducks. Wolfman Jack immortalized XEPRS in the George Lucas movie American Graffiti.
XEPRS is a Class A, 50,000 Watt clear-channel station with a non-directional antenna daytime, and a three-tower array (directional) during nighttime hours (sunset to sunrise). XEPRS broadcasts on the frequency of 1090 kHz, a United States and Mexican clear-channel frequency.
Today's 1090 AM started out as 150,000-watt XERB on 730 kHz. The original concession was awarded to Manuel P. Barbachano, grandson of one-time governor of Yucatán Miguel Barbachano. The concession was sold to Radiodifusora Internacional, S.A., in 1939; not long after, the station moved from 730 to 1090. XERB was sold to Interamericana de Radio, S.A., in 1950.
In the early 1960s, Robert Weston Smith (a.k.a. Wolfman Jack) was living in Del Rio, Texas and appearing on the "border blaster" AM radio station XERF. After several violent incidents at XERF's transmitter, Smith and partner Marvin Kosofsky (called "Mo Burton" in Wolfman Jack's autobiography) purchased daytime-only AM station KUXL in 1964 in Minneapolis / St. Paul, Minnesota. Smith relocated to Minnesota and never appeared as Wolfman Jack on KUXL, but rather worked as the station's general manager while shipping Wolfman shows on tape to XERF.
