XHFAJ-FM (better known as Alfa 91.3) is an English-language Top 40/CHR format radio station in Mexico City, broadcasting on the frequency of 91.3 MHz.

XHFAJ-FM broadcasts in HD.[2]


The station began broadcasting in 1968 as Radio Sinfonía de México airing classical music. In 1973, it was sold to the concessionaire of XEQK-AM and began simulcasting that station.

After being sold again to Radio Programas de México, the station was relaunched on July 12, 1986 with its current name, airing then-current music in English.

In 1995, the station's format switched to electronic music and Eurodance, and during that time even became Mexico City's most-listened station for several months, but as the decade ended and dance music declined in popularity, Alfa returned to be a Contemporary hit radio format by 1999. From 2000 to 2003, it even added some Spanish-language hits.

During the 2000s, Alfa Radio mostly remained with a CHR format, focusing on rock, pop and hip-hop music.

By 2009, after gradually losing audience due to competition with similar stations such as XHDFM-FM, XHSON-FM and XHPOP-FM, it changed its programming to focus on music from the 1990s with few current songs.

On January 13, 2010, popular radio host Toño Esquinca, who had a month earlier resigned from XHDFM-FM, moved to Alfa with his show La Muchedumbre, airing everyday from 6:00 am to 1:00 pm. The station's programming was modified to include songs from the 1980s as well, trying to mimick XHDFM's format, but they were gradually phased out. Currently, 2010s rock, pop and electronic music form a large part of the station's programming, with the only notorious variation occurring during La Muchedumbre when the station often airs alternative, classic English and Spanish-language rock.

From November 2012 to January 2014, La Muchedumbre also aired on KXOS (a station indirectly controlled by Grupo Radio Centro).

Since August 1, 2014, Monterrey's XHMF-FM also adopted the Alfa format, relaying most of XHFAJ's programming but with local advertising.
