XHRF-FM
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.
The facilities of the old border blaster XERA, which had been created by John R. Brinkley, were confiscated by the Mexican government in 1939, and Villa Acuña did not have another high-power station until February 22, 1947, when the Compañía Radiodifusora de Coahuila, S.A., headed by Ramón D. Bósquez and Arturo González, signed XERF-AM on the air on 1570 kHz. The station used XERA's old transmission site, with a power of 50,000 watts (later increased to 100,000 watts); its first day of broadcasting included a formal opening featuring programs from the chambers of commerce of both Villa Acuña and Del Rio, Texas and the presence of the Bishop of Saltillo. For many years, the station made money by selling its time after nightfall to American evangelists who broadcast in English to the United States.
Prior to 1959, XERF retained the Wilson and Howard Radio Advertising Agency to handle its United States ad sales. In that year, Bósquez and González formed a Texas corporation called Inter-American Radio Advertising, Inc. which was located on Pecan Street in Del Rio, Texas. While XERF's concession remained with Compañía Radiodifusora de Coahuila, the actual control of the airtime and the management of the facilities in Ciudad Acuña were under the control of Inter-American Radio Advertising.
The Texas company purchased a 250,000 watt RCA transmitter to broadcast an omni-directional clear channel signal on AM 1570, which originated some distance from the old XERA facilities within three new prefabricated concrete buildings with flat roofs. The sales brochure for XERF offered this explanation about the operation of the station (emphasis and wording shown as in the original text):
There is, of course, one BIG difference between U.S. and Mexican Stations, and that is a matter of POWER; American Stations are limited a maximum 50,000 watts ... a limitation that does not exist under Mexican regulation. X.E.R.F. for example, is licensed to operate on 250,000 watts power, and the Department of Communication and Public Works of the Mexican Government has authorized a power increase to 500,000 watts. Such power could result in serious interference if wave lengths were not strictly maintained, but the equipment with which X.E.R.F., operates assures its signal to stay "right on the beam." This is something constantly checked by FCC monitor stations, a degree of regulation by the U.S. Government alike that is imposed upon U.S. Stations. Operating on a clear channel, X.E.R.F. is heard nightly in all parts of the fifty States in the United States, Canada and Latin-America.
Although reference was made to a power increase, the station only had an RCA 250,000 watt transmitter.
The booming bass voice of Paul Kallinger was used to sell many of the products on XERF. At night, his recorded spots between the different sponsored shows served as a jingle break. Kallinger remained on the Texas side of the border and recorded his spots at a studio in Del Rio, because he did not want to become embroiled with the lawlessness that swirled around the XERF studio and transmitter on the other side of the border. In between the different religious programs, Kallinger would tell XERF listeners in various versions that:
