What is "xhcarh-fm"

XHCARH-FM (La Voz del Pueblo Hñahñu – "The Voice of the Hñahñu People") is an indigenous community radio station that broadcasts in Spanish, Hñahñu and Nahuatl from Cardonal in the Mexican state of Hidalgo. It is run by the Cultural Indigenist Broadcasting System (SRCI) of the National Commission for the Development of Indigenous Peoples (CDI). It came on air in 1998 as XECARH-AM, a daytime-only AM station on 1480 kHz. In 2012, XECARH was authorized to move to FM XHCARH-FM 89.1. While this station is on the air, XECARH cannot be shut off as it is the last radio service in portions of its AM coverage area where the FM station does not reach.
