In 2011, "La Chalmerita", an unauthorized radio station, began operation on 89.1 MHz from the Chalma municipal hall.
It was the first FM radio station in an area without broadcast television or cellular service.
[2] As the station was unauthorized, it was shut down during an SCT visit in March 2011.
[3] Given that La Chalmerita was the only station in the area and its loss was a major blow for the community, members of the community decided to form a civil association and seek a permit to begin licensed operations.
They succeeded in 2015, when the IFT awarded La Chalmerita a social use concession for a radio station on 89.1 MHz in Chalma, with the callsign XHRHV-FM.
