It is owned by Radiorama and operated by GPS Media as El Viejón with a grupera format.
XHGZ began in 1957 as XEGZ-AM 790, licensed to Ciudad Lerdo and owned by Alejandro Stevenson.
In March 2018, XHGZ converted to La Lupe, a new grupera classic hits format from Multimedios.
After a simulcast, Radiorama returned to operating XHGZ-FM as Regional Mexican "La Poderosa".
A further change in the cluster saw GPS Media's El Viejón, previously at 101.1 MHz, move down to 99.5 in August 2020.
