From 1935 to 1939, XERA was the call sign of a border blaster licensed to Ramón D. Bósquez Vitela in September 1935 to Compañía Mexicana Radiofusora Fronteriza in Villa Acuña, Coahuila. This station was the successor to XER which had been situated at the same location but whose transmitter had been dismantled after the station ceased broadcasting in February 1933. Like XER, it was under the control of Dr. John R. Brinkley of the U.S. state of Kansas. XERA ceased transmissions in 1939. After losing control of XER when it was shut down by the Mexican government in 1933, Brinkley dismantled the original XER transmitter but attempted to get a new license for Villa Acuña, Coahuila. Months later in September 1935 he was granted a new license via his partnership of Cía Mexicana Radiofusora Fronteriza company which was represented by Bósquez as the owner.
Brinkley used the old buildings of XER but installed a new 500 kilowatt transmitter with help from two Texas radio engineers. The antenna for XER had been omnidirectional, but the new directional antenna of XERA allowed Brinkley to claim that his station had an effective radiated propagation of one megawatt. One of his Texas engineers called XERA "the world's most powerful broadcasting station," which was a slogan that he would use again in the 1960s for two more of his engineering endeavors: the United States military transmitters which communicated with the U.S. submarine fleet, and again for the offshore pirate station Swinging Radio England.
Following the signing of various international treaties with the United States, the Mexican government revoked the license of XERA in the closing days of 1939. Again the equipment was removed and the location would not become the site of another, unrelated border blaster until years later following World War II in 1947. See the history of XERF for details.
