XHSP-FM

XHSP was the first radio station owned by Grupo Radio México, a corporate cousin of GRC that merged into it in 2016. It received its concession on May 15, 1973, and it was then owned by Luis Ignacio Santibañez Patino. Radio Emisora XHSP-FM became the concessionaire in 1986; it eventually became the legal owner for almost all GRC stations in Monterrey, namely those that were formerly part of GRM.

In 2020, Grupo Radio Centro put ten stations up for sale, including XHSP-FM. The station was purchased by Heraldo Media Group, and La Invasora ended programming on May 30, 2021, making way for El Heraldo Radio to move from XHCHL-FM 90.1 to the stronger XHSP.
