Digital Radio Mondiale (DRM) is the digital system for shortwave, medium-wave/AM and longwave with the ability to use existing frequencies and bandwidth across the globe.
DRM is the only authorized standard for digital high-frequency radio broadcasting, as prescribed by the International Telecommunication Union (ITU), a specialized agency of the United Nations.
DRM has near-FM sound quality plus the ease-of-use that comes from digital transmission. The improvement over AM is immediately noticeable. DRM can be used for a range of audio content, and has the capacity to integrate text, data, imagery, stereo and dual language programming. This additional content can be displayed on DRM receivers to enhance the listening experience.
American engineers and companies played key roles in the development of the DRM standard. Today, DRM is represented by the DRM Consortium and its Project Office headquartered at the BBC World Service in London.
The National Association of Shortwave Broadcasters (NASB), representing non-government U.S. HF stations, monitors DRM developments and keeps its members informed of progress in DRM services and receiver adoption.
To enjoy DRM broadcasts, you need either a DRM-capable receiver such as the Newstar DR111 pictured here, or a shortwave receiver that feeds an appropriate signal to a computer running DRM decoding software.
