History

XEYF-AM 1200 received its concession on June 11, 1993. It was a daytime-only station owned by Grupo Radiorama subsidiary Radio Universo, S.A., until its 2006 sale to Radio Fórmula. It migrated to FM in 2011.

Between the early 2010s and May 2019, Grupo Larsa Comunicaciones sold ad time and added some local programming to XHYF and XEHF-AM/XHEHF-FM in Nogales in an operating agreement with Radio Fórmula. That agreement ended May 10, 2019, and on May 13, a newscast from the Expreso newspaper began to air on the stations instead as that newspaper took over local operations.^[3] Much of the displaced Larsa programming moved to XHHER-FM 105.9. Expreso continued to represent XHYF and XHEHF through the end of 2021.
