Manuel Mascareñas built and signed on XEAF-AM in 1934; soon after, he died, leaving the station to his brother Gastón.
XEAF's concession was revoked for political reasons in 1939, after Manuel Ávila Camacho made a presidential campaign stop in Nogales.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transmission staff pulled the plug, as stations were prevented from broadcasting political content; the concession was revoked a short time later.
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.
Like other second-wave migrants owned by Radio Fórmula, the FM station offers three total subchannels, including the national Segunda Cadena feed and the Trión musical format.
