XEHF-AM/XHEHF-FM is a radio station on 1370 AM and 89.1 FM in Nogales, Sonora. It is owned by Radio Fórmula.

History

An antecedent of XEHF was the first radio station to operate in the state of Sonora. Manuel Mascareñas built and signed on XEAF in 1934; soon after, he died, leaving the station to his brother Gastón. The early XEAF broadcast at a frequency of 990 kHz. XEAF's concession was revoked for political reasons in 1939, after Manuel Ávila Camacho made a presidential campaign stop in Nogales. While XEAF, whose owners sympathized with Ávila Camacho, began to cover the event, transmission staff pulled the plug, as stations were prevented from broadcasting political content; the concession was revoked a short time later. A concession was issued on June 14, 1941, for XEHF as a 1,000-watt radio station on 1000 kHz, moved within several years to 1370 kHz. The station was authorized for 5,000 watts, but did not use all of its power often due to the expense of running at full power. Aside from the short-lived XEY, which was unable to obtain a concession and folded within a year, XEHF would remain the only radio station in Nogales, Sonora until XEXW-AM signed on in 1955.

In 1973, José Alberto Padilla Navarro became the concessionaire of XEHF. The station was sold to Radio Fórmula in 2000.

In 2017, XEHF and almost all of the other AM radio stations in Nogales were authorized to migrate to the FM band as part of a second round of AM-FM migration. XEHF will move to 89.1 MHz and change its callsign to XHEHF-FM as a result. XHEHF-FM signed on in July 2018.

Much like sister station XHYF-FM in Hermosillo, XHEHF airs Radio Fórmula programming while local advertising and other responsibilities are carried out by Grupo Larsa Comunicaciones.
