13 Feb The Brazilian public broadcaster EBC detail their plans for the shortwave trial
During the Digital Radio Technical Advisory Board meeting, on February 6th, EBC (Empresa Brasil de Comunicação) unveiled details of their shortwave DRM30 trial. Rafael Diniz, DRM supporter, who attended the meeting reports:
The tests will be held from EBC installations – in the Parque do Rodeador – on EBC’s ‘Radio Senado’ frequency. This new series of trials is the consequence of the heated debate within the Brazilian parliament on the choice of the best digital radio standard for the country. Last year at EBC seminar, General Director of Content and Programmes, journalist Eduardo Castro, said that ideally they should digitise all bands available in Brazil (SW, MW, FM and Tropical Waves) and that the enhanced service should benefit primarily their audiences.
EBC will use a Continental Lensa transmitter at power levels of 4kW, 1kW and 250W with the antenna at Brasilia beamed to Amazonia (beamed to the north). The expected coverage with be the centre and part of the north of Brazil.
