EBC, operated with the collaboration of a number of partners in the afternoon of
that day with 130W on DRM on 9755kHz. The DRM signal was succesfully received
in part of the country. In Limeira, a city in Sao Paulo state, 780 km far from
the transmitter site, Mr. Cláudio del Bianco, member of DRM-Brasil, received the
signal and could hear to the audio from Rádio Nacional da Amazônia with digital
quality.
The set-up of the system used for the test, had the support of
DRM-Brazil, and a joint effort was made. The software was provided by Content
Server and the modulator was provided by Michael Feilen. Rafael Diniz, a
DRM-Brazil member and researcher at PUC-Rio, released the DRM driver and the
first amplification stage. Members of the EBC and the Ministry of Comunicações
have provided two stages of amplification and all the required connection with
the radiant system at Rodeador Park (High Power Shortwave Broadcast Centre of
EBC).
The antenna used has a 16db gain factor and the pattern of radiation
was North-South.
On this Monday, Jun 1, new DRM SW tests will take
place.
