XHBI-FM

It was the first radio station in central Mexico, operating at 25 watts to cover the city of Aguascalientes.

In the 1940s, the station linked up to Radio Programas de México, gaining access to national advertisers and the programming of Mexico City stations XEW and XEQ.

By the end of World War II, the station had a magnetic tape recorder.

The group grew again in the late 1980s with the sign-on of XHUZ-FM, becoming known as Radiogrupo.

With the sign-on of XHUNO-FM and later the reacquisition of XEYZ-AM, Radiogrupo would grow to own six stations in Aguascalientes.
