XEPRS-AM (1090 kHz, The Mighty 1090) is a commercial AM radio station licensed to Playas de Rosarito, a suburb of Tijuana in Baja California, Mexico. It broadcasts an English-language sports talk radio format serving San Diego and Southern California. Owned by Interamericana de Radio, S.A. de C.V., it is operated and programmed by the U.S.-based Broadcast Company of the Americas (BCA). XEPRS features local sports shows and syndicated programming from the ESPN Radio Network.

XEPRS is a Class A, 50,000 watt clear-channel station using a non-directional antenna in the daytime. But because it must protect other Class A stations on 1090 AM, at night it uses a three-tower array directional antenna.[2] The daytime signal can be heard over much of Coastal Southern California and parts of Baja California. An night, the skywave signal extends over much of the West Coast of the United States and Northwestern Mexico.


XERB: The Mighty 1090

Today's 1090 AM started out as 150,000-watt XERB on 730 kHz.[3] 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. Several years later, the station moved from 730 to 1090, powered at 50,000 watts. XERB was sold to Interamericana de Radio, S.A., in 1950.[4]

In the early 1960s, Robert Weston Smith (a.k.a. Wolfman Jack) was living in Del Rio, Texas and appearing on the 250,000 watt "border blaster" radio station 1570 AM XERF, just over the Rio Grande in Ciudad Acuña. In 1964, after several violent incidents at XERF's transmitter, Smith and partner Marvin Kosofsky (called "Mo Burton" in Wolfman Jack's autobiography) decided to relocate to an American radio station. They purchased Minneapolis-area daytimer station AM 1440 KUXL. Smith moved 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.

In 1965, Smith made an arrangement with the U.S. agent to program another border blaster, 1090 XERB in Tijuana. Smith began selling ad time on the Mighty 1090 and recording Wolfman Jack shows for his new affiliate. Initially, Smith controlled the station's affairs from Minneapolis, but in 1966, Smith, along with fellow KUXL staffers Ralph Hull (a.k.a. Preacher Paul Anthony and The Nazz) and Art Hoehn (a.k.a. Fat Daddy Washington), relocated to Southern California to run XERB full-time.

Wolfman and his associates were able to make the station turn a large profit by selling 15-30 minute blocks of time to radio proselytizers. The preachers were able to pay for the time by asking their listeners to send them donations. Because they had such a large following and made so much money, the radio evangelists were willing to pay sizable fees for airtime.

In addition to the paid brokered programming, Wolfman began broadcasting his own pre-recorded shows on three different high-powered Mexican stations at different times of the day: XERB, XERF, and XEG 1050 kHz in Monterrey, Nuevo León, powered at 100,000 watts. Wolfman courted advertisers who enjoyed his brand of rock and roll music and his howling personality.

According to his biography, by 1971 Wolfman was making a profit of almost $50,000 a month. The Mexican company executives that leased XERB noticed this and got greedy. They wanted to throw him out and make all the money themselves. The owners bribed Mexican officials into politically squeezing Wolfman off the air. The Mexican government acquiesced by passing a law prohibiting Pentecostal and Evangelical religious programming on Mexican airwaves. Since XERB made most of its profits from airtime sold to the prayer-cloth preachers, Wolfman could no longer make payments to the owners each month. "That was it," Wolfman remembered. "In one stroke they cleaned out 80 percent of all the money we were expecting to make." He and Kosofsky had to return control of the station to the Mexican owners.

Some years later, the Mexican government repealed that law and allowed radio preachers back on the air. But, without Wolfman Jack howling over the airwaves, XERB never duplicated the fame he had brought it. The XERB call sign was recycled in 1986 for a radio station in Cozumel, in the state of Quintana Roo with no relation to the old XERB.

XEPRS: The Soul Express

With Wolfman out of the way, the station owners tried to duplicate his successful formula. They changed the call letters to XEPRS, programmed at night with soul music, mostly for the African-American and Latino neighborhoods around Los Angeles. The station was dubbed “The Soul Express.”[5] The call sign represented the word "Express" with the E and the X juxtaposed. Wolfman still broadcast for over a year while under the new ownership. But April 15, 1972 was the last day Wolfman was heard over the Mexican border airwaves. Airchecks of that last show are still available online. Taped versions of the Wolfman could be heard on the station around 1980.[6]

In the summer of 1972, George Lucas and crew filmed Wolfman using the studios of station KRE in Berkeley, California. Wolfman played himself for the film, American Graffiti. Although the movie shows Wolfman broadcasting live from California, the Brinkley Act made such broadcasting impossible. Artistic license was taken with the subject material for the sake of the script.[7]

Daytime Spanish - Nighttime Oldies

Through the 1970s, 80s and 90s, XEPRS aired a variety of formats in Spanish, in the daytime, while sometimes running English-language programming at night. From 1976 to the early 1980s, Rick Ward and Ron Beaton programmed oldies during the 6 p.m. to 6 a.m. skywave signal. Ron Beaton is now retired in Glendale, California, and Rick Ward is retired, living in Little Rock, Arkansas. Wolfman's old shows were broadcast from 11 p.m. to 1 a.m. on Saturday nights during this period. Early in the 1980s, DJ Sean Green[8] hosted a daily oldies show, from 7 p.m. to midnight, in English. He called it "1090 Express Radio." The show's advertisements, announced by Dick "Huggy Boy" Hugg, were mostly for oldies albums that appealed to the Lowrider culture.[9][10]

The last Spanish-language format was salsa, merengue and other forms of Tropical music as "Radio Caliente." From 2000 to 2002, XEPRS was the Spanish-language home of the Anaheim Angels, including its championship year of 2002.

Sports Radio

In 2001, another powerful AM station in Tijuana, 690 XETRA (now XEWW) began simulcasting much of the English-language sports programming also heard on AM 570 KLAC in Los Angeles and a few other AM stations around Southern California, with the moniker "XTRA Sports." Several of the AM 690 hosts and sportscasters were released, including Bill Werndl, John Kentera, and others. That left the San Diego radio market without a local all-sports station. The former head of programming for XTRA Sports 690, John Lynch, saw the void and formed the Broadcast Company of the Americas, launching a new all-sports station on AM 1090 in March 2003. He brought over most of the on-air talent released from 690 XETRA. John Lynch has another involvement in the world of sports. He's the father of the former NFL defensive back, also known as John Lynch. In addition, John Lynch, Sr., helped introduce Lee "Hacksaw" Hamilton to San Diego sports radio.

In 2004, The Mighty 1090 acquired the rights to become the flagship station of the San Diego Padres.[11] XEPRS was the Padres' home station until 2016, when CBS Radio won the rights and began broadcasting the games on Alternative Rock station 94.9 KBZT.

Beginning February 1, 2006, XEPRS started simulcasting its sports talk programming on sister station 105.7 XHPRS-FM, based in Tecate, Baja California. This operation was aimed at improving the station's signal to Eastern San Diego County as well as giving Mighty 1090 listeners the choice of hearing it on FM or AM. The station then became known as "XX (Double X) Sports Radio." News updates were produced by San Diego television station KUSI Channel 51.

On April 15, 2008 at 9 a.m., XX Sports Radio ended the simulcast on 105.7 MHz. XHPRS-FM became an oldies radio station branded as "105.7 The Walrus." This was the first FM oldies station in San Diego since XHOCL-FM flipped to a Spanish language format on September 1, 2005. As a result of the simulcast's break-up (except for Padres games), XX Sports Radio was renamed XX 1090.

In 2009, the Padres simulcast was moved to AM 1700 XEPE.

On October 6, 2010, XX 1090 became a part-time affiliate of ESPN Radio, simulcasting sister station XEPE 1700 overnights and weekends, dropping the Sporting News Radio affiliation XEPRS held since 2008.

XEPRS has also carried San Diego Toreros men's basketball, San Diego State Aztecs college football and basketball, and the San Diego Gulls AHL hockey, and has aired a few games for the Anaheim Ducks, the Gulls' parent club. Beginning with the 2018 season, XEPRS carries Los Angeles Rams football games.[12]

Return of "The Mighty 1090"

On December 17, 2012, the station re-branded as "The Mighty 1090" to coincide with the return of the Scott & BR Show.[13] On January 2, 2013, the station became the San Diego outlet for CBS Sports Radio with a line-up featuring Jim Rome's syndicated show on CBS, plus local San Diego hosts heard mornings and afternoons. The station in 2014 signed Dan Sileo to host its morning drive show.

In April 2018, XEPRS got new competition on the FM dial when Entercom switched KEGY to a sports format, branded as "97.3 The Fan."[14] It became the San Diego Padres' flagship station, taking over from co-owned 94.9 KBZT. Dan Sileo, who left XEPRS earlier in the year, joined The Fan for a morning drive time show. As a result, XEPRS gave up its affiliation with CBS Sports Radio, since Entercom owns a stake in that network and began carrying its programming on 97.3 FM. XEPRS returned to airing ESPN Radio nights and weekends, also heard on co-owned 1700 XEPE.
