It was discontinued in 1937 when the government of Lázaro Cárdenas began shortwave station XEXA through the Autonomous Department of Press and Publicity (Spanish: Departamento Autónomo de Prensa y Publicidad, DAPP).
[1] In 1968, Luis Echeverría, then Secretary of the Interior (Spanish: Secretaría de Gobernación), ordered Notimex to create a new shortwave station.

Repairing them would have cost 60 million pesos... we would have needed 60 million pesos to reach who knows who, because no one listens to shortwave any more... We cancelled the project and gave the transmitters to Radio UNAM.Radio México Internacional was relaunched by IMER as an Internet radio service on 1 January 2011,[1] to provide programming in Spanish, English, French, and indigenous languages, with programs including music, dramas and documentaries.
