On May 28, people in San Paolo, Brazil were able to experience a DRM broadcast of the Amazon National Radio transmitted from Brasilia — nearly 800 km away — for the first time, reports Digital Radio Mondiale.
The event marked the first DRM broadcast in shortwave to originate in Brazil and was a collaboration between the EBC, Brazil’s public radio broadcaster, and its partners.
According to the organization, the EBC used one antenna system at Rodeador Park for the broadcast; the antenna used has a 16dB gain and a north-south radiation pattern. The broadcast was in the frequency of 9755 kHZ and carried out with 130 W.
The coverage area is predicted to cover both the north and the south of Brazil, as well as some neighboring countries, DRM said, but tests are still occurring with more numbers and feedback expected in the coming weeks.
