XEMP-AM

XEMP-AM signed on November 1, 1961, as "La charrita del cuadrante", a station devoted to ranchera music. It was originally owned by Mercedes Rivero Arredondo de Tuero. In 1965, Rivero solicited a shortwave counterpart, which would have broadcast on 11,740 kHz as XEMP-OC. On September 30, 1976, XEMP was transferred to Radio Visión Mexicana, S.A.

When IMER was incorporated in 1983, it became Opus 710, a culturally-oriented format; this migrated to the new XHIMER-FM 94.5 in June 1986. However, in September 1985 and in the aftermath of the earthquakes that hit Mexico City, XEMP became a news station known as Radio Información. This gave way to tropical music in 1990 and Mexican regional again in the 2000s, which in turn yielded to Spanish-language rock in 2008 as "Interferencia 7Diez".

The station returned to its roots as a regional Mexican music outlet on February 1, 2014.^[2]
