XHRF-FM
XHRF-FM is a radio station in Ciudad Acuña, Coahuila. It gained fame on the AM band as XERF-AM, a Mexican clear-channel station on 1570 kHz and a 250-kilowatt border blaster owned by Ramón D. Bosquez and Arturo González, used by famed disc jockey Wolfman Jack. Now branded as 'La Poderosa, it is owned by the Instituto Mexicano de la Radio (IMER), a Mexican public broadcaster.
In earlier times, the station was operated under the laws of Mexico by Ramón D. Bósquez. Once world-famous, XERF commenced operations in 1947, receiving its concession on November 11 of that year, using the old facilities of John R. Brinkley's XERA, which ceased broadcasting in 1939. XERF was not a continuation of XERA.
