Abstract
This work presents the results of DRM+ field tests in the VHF band II (FM band) using a low power FM station, which is known in Brazil as Community Radio. The purpose is the assessment of on-channel simulcast transmission, which will exist during the transition period to digital transmission (the so called “analog switch-off”). The results from trials performed in Brasilia showed that the achievement of the same analog coverage area with digital system is conditioned to a ratio of 10 dB between analog and digital power levels, which can impairment in the current channelization.
