DAB queries
 
I would be very grateful for some advice about what may happen to my FM
radio reception when eventually it is decided to switch everything (or
almost all) to DAB.

At present I have a Beocentre 2200 to which I know I will either have to
fit internally or externally a FM aerial.

When the DAB system finally takes over, and I suppose my favourite
programmes (Radio 3/4/Classic & Jazz FM) switch to this, how will I be
able to access them without buying a totally new & updated system? Is
there some sort of magic Gizmo or converter that B & O has or is
planning (or indeed any other firm) that will enable me to listen to my
favourite programmes - and possibly access those already available such
as BBC7 ?

At present I do not have a Digital TV.

Advice appreciated.

I really wouldn't worry about it at all. It will be a very long time yet
before FM is switched off. In fact FM has never been so popular with
broadcasters. OFCOM, those who give out the broadcast licences are
scraping the barrel in some locations for spectrum for further services
and for each service there are numerous applicants.

Even when and "if" they do its got to be to a totally new radio as even
current DAB units won't tune over band 2 thats where FM now is (87.5
to108) so a totally new radio and system will be called for then.

Anyways, look at medium and long wave, still chugging along since
Marconi was a lad;)

You should have an external aerial connected to this in any case.

Your not missing much then, the picture is still better on analogue as
is the radio, FM over DAB!.....

Advice appreciated.

I doubt that DAB will come in as fast as they want Germany has stopped building DAB transmitters and some
transmissions have stopped
They have some of the higher quality output as well.

A freeview box plugged into tv do a download of whats on in your area then deleat tv channels then plug into your
pre amp much better quality

Classical FM is only decent channel missing

Fingers crossed my kids school keeps going this year, our main problem is we and the school on top of hill so we
can get there but no other buggers can get up the hill

Schools name "Hilltop" :-)

It is however available by satellite. There are also a couple of good German
stations: Bayern 4 Klassik and HR Klassik on Astra 1


Quite a number of satellite receivers provide a digital audio output. So far I
have found very little HiFi equipment that will accept a digital input. -
Suggestions welcome.

I assume that the DAC in a HiFi system would be better than I am likely to find
in a satellite receiver.

To my mind satellite is quite an acceptable medium for HiFi transmissions, since
HiFi equipment is typically in a fixed location, and there is room for plenty of
bandwidth!

Bayern Klassik is 256kbps as well. I've uploaded a recording that
someone sent me if anybody is interested:

A cheap way to get a DAC is to get a Sony Minidisc player, make sure
there's no MD disc in the player, press record, and it goes into
DAC-mode, if the MD player has a digital audio input, obviously, but I'd
imagine all, or virtually all of Sony's do.

That's a pretty safe bet.

It's just a pity that the BBC don't want to increase the bit rates of
their services, despite the fact that they've got 200 Mbps of capacity
at their disposal on satellite, with about 80 Mbps being used for the
different regions of BBC1 and 40 Mbps being used for BBCi, while the BBC
network radio stations (e.g. all the ones on the BBC DAB mux) have to
get by with just 2 Mbps. Obviously, the BBC could easily increase the
radio stations bit rates to provide good audio quality without affecting
anything else (you wouldn't miss 0.6 Mbps off the 80 Mbps of BBC1
bandwidth), but they choose to provide lowish bit rates, almost
certainly to minimise the difference between DAB and satellite. See:

Yep excellent except that Radio 3 and Classic FM are over on ASTRA at
28.2 east whilst Bayern and HR are on ASTRA 19.2 bit of a bummer but
nowt two LNB's and an offset arm and Diseq switch won't sort out:)

Get another on Hotbird at 13 east and even more comes out of the wood
work. France Musique even, at 256 K BBC please note...some hope..

Err No not really;( Audiolab do a nice DAC but thats not cheap Behringer

Yes but the self contained one It'll be good enough. After even Bayern
is at 256 K, no ones using linear PCM!..

To my mind satellite is quite an acceptable medium for HiFi transmissions, since
HiFi equipment is typically in a fixed location, and there is room for plenty of

Its a very acceptable medium, IF and only if the bitrates are high
enough. And as you say plenty of bandwidth.

However there is still a lot of snobbishness around having a satellite
dish. Our neighbour loves Jazz and when I told him that he could get
around 3 good Jazz stations on sat, he looked downcast when I told him
he would "have" to have a dish!.....

People associate satellite TV with Sky (and maybe football).

Not helped by the BBC 'how to get satellite' web page which says 'call sky'.
(Not such a bad deal if you dont mind the phone connection). There are very few
satellite equipment shops. Very little advertising of the Non sky options and
what there is tends to be for porn.

Personally, I think a BBC/ITV-led Freesat platform is going to happen
and C4/E4 and five will end up on it too.

Something like 87% of all Freeview viewing comprises of people watching
the big 5 channels, whereas on Sky they've got hundreds of channels and
usually a fair bit of premium content to choose from, so the big 5
channels would be far better off having as many people with Freeview and
Freesat as possible, because otherwise their viewing figures will just
continue falling.
