DAB+ will replace FM in the long term. This will benefit broadcasters and their listeners alike, because transmission costs for digital radio stations are only around 20% of those for FM services. Digital radio is also better for the environment along the entire value chain. Each station needs only 10 percent of the energy consumed by FM radio listening, partly because only 210 transmitters are needed for 18 stations in Switzerland. By comparison, 853 are currently needed for just four FM stations.
The DRM Consortium and Nautel are pleased to announce a special digital DRM broadcast schedule during the International Broadcasting Convention (IBC) in Amsterdam. Courtesy of transmission infrastructure provider Teracom A/S, DRM transmissions will be heard during IBC on 243 kHz throughout much of Northern Europe carrying BBC programming. Teracom installed a DRM capable Nautel NX50 transmitter at the Kalundborg (Denmark) site in 2011, with this being the first DRM broadcast of this transmitter type on longwave.Ruxandra Obreja, Chair of the DRM Consortium is very pleased to offer this service during IBC and said: “We welcome this opportunity to demonstrate how efficient, DRM AM digital broadcasts can be. All those interested will be able to experience a high quality listening experience”.On Sunday, 9th September, during Nautel’s DRM event (stand #8. C61) 15:00-17:00, a brief recording of the broadcast will be played so attendees can hear the clarity of a DRM broadcast over AM.Hal Kneller, European Sales Manager from Nautel and member of the Executive Committee of the DRM said: “We are very pleased to co-sponsor the DRM broadcasts during the IBC Show from the historic 1927 Kalundborg transmitter site”.Transmitting just 10 kW of DRM provides equal or more coverage than the normal 50 kW of analogue transmission from Kalundborg. The BBC content will be a variety of music and speech, allowing DRM listeners to hear the full breadth of FM-like sound quality, available over the very wide coverage area of longwave transmissions, free of static and fading, as well.
