XHFX-FM
XEFX-AM 630 received its concession on March 31, 1955. The 250-watt station was owned by José Ramos Regalado and Guillermo Acosta Ochoa. In 1967, XEFX was sold to Radio Sonora, S.A., and in the 1980s, XEFX increased daytime power to a full kilowatt. XEFX migrated to FM in 2010 as XHFX-FM 101.3. It remains on air because five people would lose all radio service were it to close, per a 2018 IFT study.
