History
XEHX-AM was granted its concession on June 4, 1952. Initially owned by Gerardo Millán Ríos, the station was transferred to María Elena Coral Otero de Chávez in the 1960s following her divorce from Millán Ríos. It operated as a daytimer with 1,000 watts, first broadcasting on 1370 kHz before moving to 1460 kHz. In 1971, it was sold to Radio Yaquí, then to Sistemas Publicitarios y de Mercadotecnia de Obregón in 1992, and finally to XEHX, S.A. in 1994. In 2006, XEHX relocated from 1460 kHz to 860 kHz, maintaining its 1,000-watt power output. In October 2011, XEHX received approval to transition to FM, rebranding as XHHX-FM 101.7.References
