Momentum is growing behind DRM+, with an increasing number of commercial broadcasters interested in the enhanced version of the Digital Radio Mondiale system intended as a replacement for AM transmission. A trial got underway in Norway during May, following previous tests by French radio stations and scientists. DRM+ extends the original system, which is based around broadcasting bands below 30MHz, into VHF bands up to 108MHz. The trial in France took place in Brest using a 300W Harris transmitter in Band II. The project was overseen by Telecom Bretagne University, using the Digidia Soprano+ DRM+ modulator and Alto+ DRM+ server. The Norwegian tests ran into June and were based around commercial radio network Venture 21 in the city of Trondheim. Signals were broadcast using a Nautel 300W transmitter from a Digidia server, again in Band II. Among those involved were Fraunhofer IIS and RFmondial. Commenting on the trials, Ruxandra Obreja (pictured), chair of the DRM Consortium, says, "We are proud of the support and technical expertise we are getting from our key members supplying transmitters, content servers, modulators and full DRM USB receiver solutions. In Europe we are demonstrating that there is a cheap and effective solution for also digitising small radio stations - commercial and community - which can run on their own or complement other multiplex solutions." www.drm.org
