DRM-DMOD3 -Compact and Reliable

Despite new emerging technologies to distribute radio via web, cable and satellite, terrestrial broadcasting is still undoubtedly the most efficient and convenient program distribution medium for large area coverage, particularly for mobile applications.
The major advantage of broadcasting in the frequency range below 30 MHz is the huge coverage. While all the other technologies need an extensive network or a high number of transmitters, AM broadcasting can provide a program to particular target groups in a large geographical area with just a few transmitters.



Digital Radio Mondiale (DRM) is the name of the international consortium, which defined the standards for digitalisation of AM broadcasting. DRM enables broadcasters to combine the advantage of VHF quality with the national and international coverage of AM broadcasting. TRANSRADIO, formerly TELEFUNKEN SenderSysteme Berlin, as a founding member of this consortium has tremendously influenced the standard with its experience and knowledge in broadcasting.


DRM Overview

Typical DRM System with two Transmitters in active Reserve


As DRM is the sole digital broadcasting system using the same frequency range and bandwidth as the existing analogue systems, broadcasters are offered major advantages as they can use the same frequencies and often the same transmitters as before. For more detailed information please refer to drm.org and the Broadcasters Introduction & Implementation Guide.

TRANSRADIO offers new DRM installations and the upgrade of existing transmission systems.

TRANSRADIO became the world market-leader for DRM technology and looks back to the highest number of installed DRM systems worldwide.
