History
The station began broadcasting in 1968 calling itself La Hora Exacta with the original callsign XEQK-FM in simultaneous transmission with XEQK-AM 1350 KHz on medium wave and XETT-OC 9555 KHz on short wave. After its sale in 1986 to Radio Programas de México, the same operator of Radio Red 1110 AM and Radio VIP 88.1 FM, it changed its name and programming to Alfa 91.3, which began broadcasting on July 12, 1986 as a music station in English from youth court competing in parallel with Rock 101, WFM 96.9 and Kosmo 103.3. Alfa was created by Clemente Serna Barrera. Its forerunners included Martha Debayle, Rocío Barbabosa, Eddie Muller, Eduardo Vallarta, Claudia Arellano and Luisa Carrandi. From 1995 to 1999 Alfa broadcast music from the dance and electronic genres. Between 1996 and 1997 it became the most listened to in Mexico City. In the early 1990s, the station identified itself with the nominal call sign XHRCA-FM which in 1996, after the purchase of the station by Grupo Radio Centro, changed its call sign to XHFAJ-FM in honor of Francisco Aguirre Jiménez who was founder of the media consortium. In 1999 the station enriched its profile with the inclusion of genres such as rock, pop, hip-hop, techno and house. Between 2000 and 2003 Alfa included music in Spanish in its programming, this period being the only one in which music of this type was broadcast to date. Given the rivalry with other radio stations in the market, Alfa lost audience in 2007 and 2008 and in mid-2009 it decided to modify its programming to transmit mostly music from the 1990s combined with the current one. 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 every day 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. During ''La Muchedumbre'', however, it's common for the station to play both English and Spanish classic and alternative rock. Also, for a time after the demise of GRC's pop formats, Latin urban music joined Alfa's programming, though it was removed by the end of 2020. From November 2012 to January 2014, ''La Muchedumbre'' also aired onReferences
