Stuart Owens: Ofcom | Tech Parameters still shows Coventry being on 12D.
According to Radio Today | Regional DAB turned off in West Midlands "The Bromsgrove transmitter frequency block will transfer over to MuxCo Herefordshire and Worcestershire from September 2013."

Stuart Owens: I'm not sure. All the plans say that Coventry & Warwickshire is staying on 12D.
12A is listed for Lancashire, London (Switch) and Swansea.
The "MOU" says only Manchester, Liverpool, Humberside, Plymouth, Ayr, Inverness, Leicestershire and Peterborough get "frequency changes"

John: It does appear that BBC local radio is listened to a lot, and has been since it was created.

Ian: My only recollection of Schools Radio was a rather harrowing description of people on the Titanic, aged about 10.
I think we mainly watched Schools TV, and that for only a couple of half-hours a week.

MikeP: You are correct, the limit frequency for digital record is known as the Nyquist limit. It's half the sample rate, so it's 22.05kHz for a standard CD.
I'm interested to know what recording equipment you are using that will store and reproduce up to 30kHz.
It is argued (and I believe I have seen demonstrated to my satisfaction) that there is no need to record frequencies above 22kHz as the recording device will be able to record the harmonics that will be within the hearing range of humans and provide the listening experience.
Of course, when you are at a live event, be it an organ or sound system, you will be experiencing a lot of hearing by bone conduction - Bone conduction - Wikipedia, the free encyclopedia - but this tends to enhance bass frequencies, rather than the top end.
I spent a lot of childhood listening to reporductions on QUAD ESL electrostatic speakers, as my godfather was employed there.
