[HCDX] DRM Enters Tropical Band
DRM Enters Tropical Band

At the 2007 World Radiocommunicaton Conference (WRC-07) in Geneva,
the International Telecommunication Union approved the DRM system for
use in tropical-band broadcasting.
Since 2002, the ITU has endorsed DRM for international broadcasting in the
long-, medium- and shortwave frequency bands, with the exception of the
tropical zone 120, 90 and 60 meter bands. These bands are the frequencies
near the lower end of the shortwave spectrum reserved for domestic
broadcasting purposes in countries located roughly between 30 degrees
North and South latitudes.
The ITU has now sanctioned the implementation of DRM between 3,200
and 5,900 kHz, thus opening up a significant market for broadcasting in
tropical areas.
"The recognition of the DRM system is now totally worldwide for all digital
radio applications of various types around the world in the traditional
broadcasting bands below 30 MHz - longwave, medium-wave and
shortwave," said Donald Messer, DRM representative at the WRC.
Additionally, the DRM Consortium is testing an adaptation of its system to
VHF bands I and II. When complete, the system will be available for
worldwide use in all terrestrial broadcasting bands up to and including the
FM band (VHF band II). ________________________
