DRM+ trial in the UK in first quarter of 2011

The DRM Digital Radio Mondiale standard was extended in 2009 to add an
additional mode for operation in the VHF broadcasting bands (known as
DRM+), enhancing the established capability of DRM for digital radio
services in the bands below 30 MHz.

DRM provides many features to allow user-friendly, high quality radio
to be broadcast, including use of station names rather than
frequencies, consistent digital audio, additional text and
visualisation, an EPG, alternate service signalling, and automatic
service following to DRM, DAB, FM and AM services.

After the successful trial in Sri Lanka (November 2010) the DRM
Consortium will mount a comprehensive DRM+ trial in the UK. The trial
will take place in the Edinburgh area of Scotland in the first quarter
of 2011.  Its objectives are:

       • To measure the coverage of DRM+ operating in various transmission
modes (lower capacity, higher ruggedness; higher capacity, lower
ruggedness)
       • To compare the coverage of FM and DRM+ in terms of transmit power
       • To assess the impact of DRM+ on FM and vice-versa
       • To demonstrate the performance of DRM+ in a range of environments
throughout the coverage area, for example, urban, suburban, rural,
etc., and therefore provide an analysis of performance in the presence
of multipath interference, terrain shielding, man-made obstructions,
etc., in both strong and weak signal areas;
       • To measure the pattern of the antenna in order to correlate
performance in different directions with expected performance;
       • To provide suitable measurement data to international regulatory
bodies, such as CEPT and ITU.
