According to their website Archived 2005-04-04 at the Wayback Machine, they transmit "from various places in Chiapas directed to the Zapatista bases, the insurgentes and milicians, the commanders and local people in general".
[6] Radio Insurgente has also used criticism and humor since its first broadcast, when it mocked U.S. foreign policy, Silvio Berlsuconi, Tony Blair, José María Aznar, the King of Spain, and Judge Baltasar Garzón.
[9] The station was not sanctioned by any national laws and lacked a proper license, yet the San Andrés Accords between the EZLN and the Mexican government held that the indigenous communities had a right to broadcast their own content.
In July 2006, Subcomandante Marcos was prevented from appearing on XENK-AM Radio 620 in Mexico City because of a fear the state would discontinue advertising on the station.
Furthermore, Radio Insurgente aims to inform listeners of the progress of the autonomy process within the Zapatista zones and promote the words and music of the indigenous Chiapas communities.
[12] The Internet audio version of the radio network was launched in November 2004 to celebrate the 21st anniversary of the EZLN movement and focused on recordings of local indigenous musicians and story-tellers to political speeches by movement leaders and helped to serve as a recorded history of Mexico's indigenous people.
The EZLN has said that access to and control of the media are vital for its survival and have thus worked quietly to build their capacities in order to speak directly to their people.
When Radio Insurgente first began broadcasting, the popular music that they played combined with the reading of "saludos" from their listeners led some government loyalists to unknowingly tune in.
The one-hour program focuses on current events in Chiapas, the history of the EZLN, indigenous women's rights and many other subjects.
