XESMR-AM received its concession on October 1, 1986. It was owned by Adrian Loreto Pereda López of Radiorama and broadcast with 1,000 watts. XESMR was sold to Radio Fórmula in 1989, and the concession was transferred a decade later.

In late 2010, XHSMR-FM 90.1 came to air. The AM-FM transition was completed when XESMR ceased broadcasting in April 2014.

In April 2017, XHSMR flipped to the Trión alternative rock format from RF, maintaining RF's national news programs.
