If this is correct those who oppose the FM switchoff are certainly not Luddites but realists. Pigs ear is an understatement.

dave griffiths: The local DAB multiplex operators do improve their coverage sometimes.

DRM+ in UK
Preparations have started for the DRM+ trial in the UK, with equipment being set-up and tested in London before being sent to the transmission site in Scotland. All going well and with weather permitting, the test transmissions should start in early February.

DRM+ TRIAL IN THE UK -This is good news! If DRM were moribund, this would not be happening! Extract from drm.org below:-
--------------------------------------------
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.

michael: It is very interesting, but probably just far too late.

Drm+ what exactly is this and will you need New equipment to receive it?

DRM+ is a vhf implementation of DRM. I assume it will need a modified Linux software implementation on the PC processing the signal from the vhf receiver. Details will presumably be available from the DRM Consortium. Reception on vhf will, of course, only be possible in the Edinburgh area. As Brian states, DRM is not going to overtake DRM now, but ongoing research suggests it is still considered a possible future option. I received a very informative response from a BBC engineer to an enquiry about DAB and FM options planned for Devon which included a mention of the former DRM trial conducted from Plymouth.

Brian can you put this general DIGITAL RADIO thread back on the Digital Radio Home Page for easier access please. Ta
