History

XEFZ received its concession on March 29, 1971. It operated on 1110 kHz as a 250-watt daytimer. Not long after, XEFZ moved to 660 and ramped up its power to 10,000 watts.

On January 4, 2021, XEFZ switched from news/talk "ABC Noticias" to sports talk "ABC Deportes". At the same time, XHGBO-FM 92.1 was switched to simulcasting the new sports talk format from carrying sister station XEBJB-AM 570.
