Not very well planned DAB was it. To sell car radios wouldn't it have been better to have agreement EUROPEWIDE or even WORLDWIDE. I cry on Friday nights every time my BBC Radio DAB tuner goes into MONO on Radio 4 at the start of ANY QUESTIONS & THE FRIDAY PLAY both in stereo on FM.
Why can't the government give the BBC more capacity. They are an excellent broadcaster but are being stifled by idiots who are playing at politics but not providing an adequate service to the nation, which doesn't seem bothered anyway, in the main, ready to accept quantity over quality and soon that's all we will know.

So poor old Jimmy Savile sadly departs this world. Apart from his UK radio broadcasts I used to tune into 1413kHz MW from Masirah Island every Monday morning to hear the VINTAGE CHART SHOW in OMAN in 1987-88 hosted by Jimmy on the BBC WORLD SERVICE in the good old days when it used to broadcast a good variety/mix of programmes including music, drama, comedy, book readings, documentaries, Waveguide (programme about radio and technology), science, On the Move (transport), entertainment, UK News and much much more, rather than the very boring almost rolling news, sport and business news, highly repeated schedule of today. GOD BLESS YOU JIMMY (and the Duchess of course). Hope the "guys & gals" at the BBC see sense one day and revert back to type and FIX IT.

Has anyone worked out how many people will lose radio altogether in areas of the country both in cars and in houses in remote, hilly and coastal areas when FM, MW and especially LW are all switched off.
DAB will not be able to give continuous coverage in these areas : West Highlands, Lake District, parts of the Peak District, Glencoe, coastal areas, Cornwall, Wales, to name but a few. Not many car radios have DAB fitted as standard, even NOW ?

I hear on FEEDBACK that the main UK LW transmitter near DROITWICH (as seen from the M5) is effectively being left to dies as engineers will not replace certain parts when they fail. So no fixed date just a petering out !!

Apparently it uses some HUGE (3ft diameter) final transmission valves that are no longer made. BBC has bought all world stocks - 10 of them - and they last months to years.
I find it very hard to believe that modern man is incapable of making a big signal on 198 somehow!.
Is it true that DAB car radios will not work in Europe?

Ofcom has announced further reduction of some DAB bitrates to get more stations and more revenue in. Subjectively, music does not sound as pleasing on low bitrates as on FM. In the current economic climate, the overall costs of full versus delayed switchover to DAB and use of FM must have become an unwelcome issue. 198kHz and regional MW transmitters will be sacrificed. Coverage and service provision in many areas may well suffer, particularly on the road and on home portable receivers. It's called progress. Sad, as DAB could have become a great success, had it been better planned from the outset. One should nevertheless contribute to the current public consultation.

Nedbod: Couldn't agree more Michael. Almost makes you think there might have been a hidden agenda. Like money received by certain elements for selling off the airwaves ?.

@ SteveP
DAB car radios will work throughout Europe (and Australia/New Zealand) because they are World DMB Profile 1 compliant (they will receive DAB, DAB+ and DMB-R transmissions).
They won't work in the USA or Japan because those countries have adopted non-World DMB digital radio systems.
@ Nedbod
The BBC proposes to switch off the MW transmissions for local radio in England except for Derbyshire & Gloucestershire to save transmission costs. There are areas of Derbyshire & Gloucestershire which have no FM local radio coverage so MW has to stay.
Radio Jersey & Radio Guernsey MW transmissions will also be retained as they broadcast the parliamentary proceedings.
@ michael
Ofcom does not regulate the bit rates of BBC DAB services and no BBC services have reduced their bit rates in the last ten years.
Ofcom's regulation for the commercial stations is based on a minimum sound quality diffgrade measure of -2.0. The latest MP2 encoders will achieve this measure with a bitrate of 112kbps for (joint) stereo broadcasts.
There is no regulatory requirement for DAB stations to broadcast in stereo, it's a commercial decision for each station. Some stations such as Jazz FM have gone for 80kbps mono because it provides reasonable sound quality on a DAB portable (the kind that most DAB radio owners have).

DAB v FM v MW: BBC local radio is not receivable on FM or DAB in many remote, valley and coastal areas, only on AM (and webradio). DAB in-car reception is very patchy in many rural areas. Our AM transmitter is due to be closed down. Predicted advertising revenue informs commercial DAB operator plans for reduced coverage on DAB for mobile and portable reception - which BBC local radio could piggyback, but with reduced coverage compared to FM and AM now. Better AM than nothing at all! Better low bit-rates than nothing at all! The economic downturn may well disadvantage reception in rural areas.
