During May and June 2017 experimental DRM transmissions were resumed by Brazilian Public Broadcaster (EBC) from the Rodeador Park, where Rádio Nacional transmission facility is located. Different antennas and frequencies were tested, and reception reports from places more than 1000km away were received.
The transmissions are being carried by Brazilian Digital Radio
Association (ABRADIG) in partnership with EBC. The intention of these
low power transmissions is to raise awareness of the DRM digital radio
system for the broadcasters and the new government towards its adoption
as a national standard and to enable permanent high-power DRM
transmissions from EBC.
