XEFR-AM

Radio Felicidad received its concession in 1952 and came to air in 1963.

In 1994, the station became Radio Capital and in 1997 the station flipped to rock-formatted as Óxido 1180. That format was discontinued in early 1998 in favor of sports talk as Super Deportiva 1180; it lasted until 2001, before Grupo ACIR decided to flip the station to its regional Mexican La Comadre format (which returned to Mexico City from 2015 to 2021 and since 2022 on XEL-AM 1260). This, too, did not last long, before the Radio Felicidad name and format, which had been associated with the station in its early days, was restored in 2003.

XEFR is the official radio station of the Diablos Rojos del México baseball team and carries their games.
