Abstract :
The DRM+ (Digital Radio Mondiale) system is the extension up to 300 MHz of the DRM digital radio broadcasting system. During 2010 three different trials were conducted in Brazil with DRM+ system in VHF band II (popularly called FM band). These trials were defined to have a big, medium and small coverage area for big, local and community broadcasters. For this purpose, different transmission powers were used. The transmission was done with only DRM signal in low power trial. In the high and medium power trials the transmission was done in “combined mode”, that is, the FM and DRM+ signals were transmitted in adjacent channels from the same transmission site. In this paper the results of these trials are explained and compared with theoretical values.
