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.
