History
The station began as XEDH-AM 1340, with a concession awarded to Vicente Hernández on January 13, 1938. In 1949, the station was sold to Óscar González Galindo, and in January 1987, it became part of Grupo RCG with its concession owned by Roberto Casimiro González Treviño.

In the late 2000s, XHDH was sold to Nova Teleradio. In 2012, it migrated to FM on 91.5 MHz.

In September 2021, Grupo Región began operating the station; it rebranded as "Región 91.5 Exa FM" with no change in format.
