in Oaxaca (southern Mexico) is the first indigenous radio station that comes to mind for me. It broadcasts in Spanish, Amuzgo, Mixtec, and Chatino. XEJAM is just one of many indigenous Mexican radio stations, specifically the one in Oaxaca that's part of this list
In central India, there is CGnet Swara, where indigenous people (Adivasis or "tribal people") can report news through their mobile phones and achieve change without having to deal with the bureaucracy.
