XEMO received its first concession on January 2, 1934. It was owned by Fernando Federico Ferreira. In 1960, the station was knocked off the air by a fire, started when a transmitter short circuited and ignited a rug, that caused $50,000 in damage.[2]

After Ferreira's 1964 death,[3] Gustavo Faist Fernández became the new concessionaire. In turn, Faist transferred the station to Gustavo E. Astiazarán Rosas in 1969. In 1973, the concession was placed under its current concessionaire.
