LA KEBUENA 105.1 (Mazatlán)

XHERJ-FM is a radio station on 105.1 FM in Mazatlán, Sinaloa, carrying the Ke Buena grupera format from Radiópolis. It is owned by Promomedios Sinaloa.

The station traces its history to XERJ-AM 1320, which received its concession on January 10, 1940 and was owned by Oscar Pérez Escobosa. It was transferred to Radio Mazatlán, S.A. in 1958, and by the 1960s it broadcast with 5,000 watts by day and 500 by night, a power level it retained for decades.

XERJ migrated to FM in 2010 as XHERJ-FM 107.5. As part of the 2017 concession renewal, the station moved to 105.1 MHz on July 8, 2018 in order to clear 106-108 MHz as much as possible for community and indigenous radio stations.

In March 2026, XHERJ dropped the "La Nueva RJ" name and became a national Ke Buena outlet from Radiópolis, after XHST-FM 94.7 ceased operations on December 31, 2025.
