Cultural Indigenist Broadcasting System

The Sistema de Radiodifusoras Culturales Indigenistas (SRCI; English: Indigenous Cultural Broadcasting System) is a network of radio stations in Mexico. The radio stations it operates are community radio stations that aim to serve different sectors of the country's indigenous peoples. Pursuant to Article 4 of the Constitution, their mission is to strengthen the multicultural nature of the nation by promoting the use of 31 indigenous languages.

The SRCI began operations in 1979 with the launch of XEZV-AM, "La Voz de la Montaña", in Tlapa de Comonfort, Guerrero. The network was initially managed by the National Indigenist Institute (INI), an agency of the federal government; the INI was, however, dissolved in 2003 and replaced by the National Commission for the Development of Indigenous Peoples (CDI), which consequently assumed control over the network.

The SRCI currently operates 19 medium wave (AM) stations and two high-power very high frequency (FM) stations. It also has four 10-watt FM stations in Yucatán and formerly held permits for three more in Michoacán. An additional medium-wave station, XENAC in Nacajuca, Tabasco, ceased operations in 1990 and its broadcasting permit was suspended in 2001.
