XHRF-FM significant person Wolfman Jack (1938-1995), radio and television personality
XHRF-FM (103.9 MHz) and XERF-AM (1570 kHz) are radio stations in Ciudad Acuña, Coahuila, Mexico.  Originally only on the AM band, XERF is a Mexican Class A clear-channel station transmitting with 100,000 watts of power.  Now branded as La Poderosa, XHRF-FM and XERF-AM simulcast their programming and are owned by the Instituto Mexicano de la Radio (IMER), a Mexican public broadcaster.
In earlier times, XERF was operated under the laws of Mexico by Ramón D. Bósquez and Arturo González, transmitting 250,000 watts as a border blaster, featuring famed disc jockey Wolfman Jack.  XERF received its concession on November 26, 1947, and commenced operations, using the old facilities of John R. Brinkley's XERA, which ceased broadcasting in 1939. XERF was not a continuation of XERA.Brief rebirth in the 1980s
In 1982, Bob Smith (Wolfman Jack) ran into a radio engineer friend named Mike Venditti, and he told Venditti that no one had been able to get XERF back on full power with its old RCA 250,000 watt transmitter, because RCA did not have any manuals relating to the equipment. Venditti then approached González with a business proposition.
