XHFQ-FM

The first transmissions were made using homemade equipment in 1937, and on April 20 of that year, the Secretariat of Communications and Public Works awarded a concession to Pedro López Díaz for a 500-watt AM radio station.

In 1985, the Cananea Mining Company, then a state-owned enterprise, reached a deal with IMER, handing over operations of XEFQ to the institute.

On March 25, 1988, IMER contracted with Nafinsa to buy XEFQ and the subsidiary that owned it, Voz e Imagen de Cananea, outright.

López Díaz remained the concessionaire in SCT records for years, even though he died in 1990.

Even worse, during an August 1989 miner's strike, the Mexican Army seized XEFQ for several days.
