Rádio Nacional Amazônia OC 11.780 AM

Rádio Nacional da Amazônia is one of Brazilian radio's genuinely historic institutions: created in 1977 to bring information to the Amazon basin, it still broadcasts on shortwave - 6.180 kHz in the 49-metre band and 11.780 kHz in the 25-metre band - from transmitters in Brazlandia, near Brasília.

Run today by EBC, the public broadcaster, after decades under Radiobrás, the station covers all of Amazônia Legal and part of the Northeast, plus an international footprint - a signal that genuinely matters for river communities with no other dial to turn to. Programming follows public-service logic: journalism, service features for remote populations, education, sports and entertainment, in Portuguese.

The station is part of the Rede Nacional de Rádio alongside its EBC sisters, and streams live online, so the Amazon's public voice reaches far beyond the shortwave footprint - free web radio to listen online, anywhere.
