XHPR began operations on 101.3 MHz some time after receiving its concession in 1965.
It was owned by Emmy Pinto Reyes, who also obtained the original concession for XHEM-FM in Ciudad Juárez.
That same year, it became Vox FM, adopting the name and imaging then used on XEX-FM in Mexico City, which it would do again in 2004 upon changing to Los 40 Principales.
The Soy FM name was adopted by the early 2010s, with XHWB-FM 98.9 becoming the new Los 40 station in the market.
In 2016, a sale to Grupo Radio Digital by the previous owners, Grupo FM Multimedios, prompted a format change to Ke Buena—which had previously aired on XHRN-FM 96.5.
