In April 1990, Alfa 91.3 was present at the inauguration of the Cabo Wabo in Baja California, Mexico, obtaining an exclusive interview with Van Halen and their new vocalist back then, Sammy Hagar, who was replacing David Lee Roth.

In January 1991, Alfa 91.3 was present during the Rock in Rio II Festival, where concerts were broadcast from Maracanã Stadium with Guns and Roses, George Michael, New Kids on the Block, Billy Idol, Megadeth and many more bands.

Alfa 91.3 FM was the first station in Mexico City to broadcast a Top 40 format with a proven radio formula that had an impact on ratings back then thanks to a man by the name of Bruce Miller Earle.

It is thanks to this mobile unit that dozens of live remote controls were carried out from the Palacio de los Deportes where the first concerts were given in Mexico City in the early 90s, with the likes of Sting, INXS, Metallica, MC Hammer, and many more.

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 every day from 6 am to 1 pm.
