National Broadcasting of Guinea-Bissau

The National Broadcasting of Guinea-Bissau (RDN; in Portuguese: "Radiodifusão Nacional da Guiné-Bissau"), also known only as National Radio (in Portuguese: "Rádio Nacional"), is a public broadcasting company in Guinea-Bissau, whose head office is located in Bissau.
The RDN operates three radio stations in the country - Bissau (in city suburb of Nhacra), Catió and Gabu -, in addition to several regional stations and an international broadcast service. A network of transmitters allows the radio to cover about 80% of the country, in frequency modulation (91.5 / 104.0 FM).
The broadcasts are made mostly in Portuguese, and also have programs in the national languages of the country, namely: Creole, Fula, Balanta, Susso, Mankanya, Papel, Bijago, Felupe, Mandinka, Manjak, Beafada, Balanta Mané, Pajadinka and Nalu.
Historic.
The current RDN arose from the merger of two important broadcasting services that were installed in Guinea-Bissau still in the colonial period, which operated with clearly divergent objectives. The oldest was the public state broadcaster, called the "Official Broadcaster of Portuguese Guinea", started in 1944, and; the other broadcasting service was called "Radio Liberation", started in 1964 on the initiative of nationalist activists who were fighting for the independence of Guinea-Bissau.
The unification of services would only occur in post-independence, on September 10, 1974.
