On February 22, 1986, Instituto Mexicano de la Radio (IMER) (Spanish: Mexican Radio Institute), a Mexican nationwide public radio broadcaster, purchased the assets of the Compañía Radiodifusora de Coahuila, S.A. The license was formally transferred to IMER on February 20, 1987. However, once IMER acquired XERF, it was left with the old, broken transmitter, for which there were no parts, and a second, 50 kW transmitter, which was also having problems, and XERF operated with only 15,000 watts. With the acquisition of a new transmitter, XERF raised its power to 100 kW in May 2004.

The goal of XERF under IMER is to provide a broadcast service that links migrating Mexicans to their original communities. The station's programming consists of news/talk programs and Mexican popular music.

As of 2009, XERF is licensed for 100,000 watts domestically, but is listed as a foreign station with 250,000 watts of power in the U.S. FCC databases.
