XHLAZ-FM

XEWP-AM 1420 received its concession on August 26, 1964. It was owned by Carmen Rodríguez de Méndez and operated from Sayula as a 500-watt daytimer.

In 1977, XEWP was sold to José Antonio Aguilar Herrera and became XEKMX-AM, later moving to 600 kHz and increasing power to 5,000 watts. During this time period, it was known as La Super X. It changed its calls again, to XELAZ-AM. The callsign change reflected the "La Z" name in use at that time.

XELAZ was approved to migrate to FM as XHLAZ-FM in 2011. The station used the La Mejor brand from MVS Radio from that time until the end of April 2022. On June 1, became a new format as La Luperrona with a Regional Mexican format until ceased the format in April 2025.
