XHDN-FM

XHDN began as XEDN-AM. Its concession was awarded on November 21, 1942, and it broadcast on 600 kHz. It originally was owned by José Bertiz, but it soon became part of Radio Programas de México.^[2]

In 1958, Luis de la Rosa took ownership of the station; de la Rosa had been the first president of the Mexican Association of Radio Stations, the predecessor to CIRT, in 1937.

In 1970, Grupo ACIR acquired XEDN, and in 1982 it became part of Radiorama.

XEDN migrated in 2011 to FM on 101.1 MHz.

In 2020, GPS Media was born, assuming control of several stations, including XHDN-FM. XHDN retained its format and rebranded as El Viejón. A further change in the cluster saw Éxtasis Digital, which had relaunched at XHERS-FM 104.3, move to 101.1 in August; El Viejón began broadcasting on XHGZ-FM 99.5. The Éxtasis Digital name was dropped in February 2021 and the station rebranded as "Wow".
