The report on the first ever DRM+ test carried out in New Delhi has been released. All India Radio and the DRM Consortium jointly organised the DRM+ showcase and workshop in the Indian capital from 23rd-27th May 2011. DRM members Nautel, Fraunhofer, RFmondial, Analog Devices and the BBC participated with all the necessary equipment and manpower and scientist Friederike Maier from the University of Hannover, Germany supervised the test and authored the report. The test was able to establish that DRM in the FM band is capable of good coverage at reduced power levels compared to analog FM. Two live radio programmes (FM Rainbow and FM Gold), a Journaline text information service and a PRBS test sequence were transmitted. The report carried measurements that were conducted in four radial directions from the transmitter located at All India Radio. The functionality of the DRM standard particularly for the VHF band (DRM+) could be presented with this field trial in the FM band II.
