XERB was the original call sign for the border blaster station in Rosarito Beach, Mexico, which was branded as The Mighty 1090 in Hollywood, California. The station boasted "50,000 watts of Boss Soul Power". That station continues to broadcast today with the call sign XEPRS-AM. XERB also had an office in the rear of a small strip mall on Third Avenue in Chula Vista, California. It was not unlike the small broadcast studio depicted in the film "American Graffiti" (which was filmed at KRE in Berkeley). It was located only ten minutes from the Tijuana–San Diego border crossing. It was rumored that the Wolfman actually broadcast from this location during the early-to-mid-1960s. Smith left Mexico after eight months and moved to Minneapolis, Minnesota, to run station KUXL. Even though Smith was managing a Minneapolis radio station, he was still broadcasting as Wolfman Jack on XERF via taped shows that he sent to the station. Missing the excitement, however, he returned to border radio to run XERB, and opened an office on Sunset Boulevard in the Los Angeles area in January 1966. The Wolfman recorded his shows in Los Angeles and shipped his tapes across the border into Mexico, where they would then be beamed across the U.S. It was during his time broadcasting on XERB that Smith met Don Kelley, who became his personal manager and business partner for more than 20 years. It was Kelley who saw the potential for Wolfman Jack to become more than a radio personality. Kelley started to work on a strategy to transform Smith from a cult figure to a mainstream entertainer in film, recordings, and television. He promoted Smith to the major media and formed enduring relationships with key journalists.
