You can find a bit of that in Yorkshire off Holme Moss near the
junction of the M62 with the M1. Mind you there is an awful lot of
the country that doesn't have this problem. DAB has problems too its
rather susceptible to lift conditions as well as the "bubblin" mud;!..

Driving round most cities with tall buildings or hilly terrain will
reveal multi-path spots. And London has lots of both. I've not heard
the bubbling mud effect on the car radio so far.

Well there are other bit's of the known universe north of the people's
republicke of Balham;)..

Ignoring the apostrophe abuse for the minute;-) I mentioned London, not
Balham. Nor is London the only city with tall buildings and hills.
But perhaps you've not noticed?

I have as it happens .. but not all of London is afflicted...


Which to me in a car sounds far worse than low bitrates on DAB.

To you maybe.. but your one of only Two people I know who have DAB
in their cars, both after fits, and the other one is a Radio
station manager..

Doncha love people commenting on things they have no experience of?

Well I have spent quite a bit of time in that car using that but the
point is thats one of only Two cars fitted anyway!..

Right. Then would you say the reception was in general better than FM?
Or any other comment? The 'audio quality' one has been done to death -
but some might find experience of the mobile reception of use to them.

It should all things be equal as it and ODFM were designed for mobile
use .. but here we have the stupid situation of Cars coming off the
production line/s without the DAB band being fitted!..

And? You can still buy TV sets without a Freeview tuner. Despite there
being a definite date for the analogue switch off.

Thats the market but its a bloody sight easier to convert an analogue TV
to freeview than a car radio to DAB..

Not that I'd want to seeing the poor bit reduced digital TV that we have
foisted on us..


And OK lets not do the sound quality issue..

We know that ****e cubed anyways....

So you keep on saying - but then apparently can't hear multi-path on FM in
your car.

Don't seem to have a problem with it..




No one else I know of has DAB in their Car. Two have fixed table
receivers mains driven...

Hardly mass market penetration is it?..

Dunno why you're asking me that. I never said it was.

OK perhaps you didn't but the point still stands...

The point still stands that FM took ages to achieve 'mass market
penetration' too - despite its obvious advantages in some ways.



Dave.. In those days they didn't have the semiconductors like we do
now!..

And?

If modern semiconductor fabrication had been around then it would have
caught on much much sooner....

I doubt it. Makers charge what the market will stand - no relation to the
manufacturing costs.


Well it looks if DAB is going tits up in Germany!..

Reckon they have a few more problems with multipath there eh?...

The coverage for FM and stereo on FM took many years to spread across the
bulk of the UK. So anyone making a product for advertising/sale across the
UK would have been handicapped by that. Plus, outside the magic circle
(London and the SE) the TXs were often fed with poor landlines or via
master-slave TX links, with dubious results. During that time the BBC and
government seemed far more interested in TV and then colour TV. As often,
sound radio was treated like a daft uncle. Ignored whenever possible, and
humoured with the minimum of attention when necessery.

All really signs of the times .. PCM didn't exist as we know it now, for
a start imagine a PCM encoder/decoder with directly heated triodes;)...

By the nature of multi-path there will be parts not afflicted. Of course
something moving relative to the aerial can cause it too on portable
equipment. FM stereo can be superb on a permanent installation - but less
than ideal on a portable or mobile one.

Not so - you can buy DAB adaptors.

And many TVs *won't* 'convert' properly unless they have auto switching
to 16:9 or you're prepared to put up with dreadful picture composition.

Not that I'd want to seeing the poor bit reduced digital TV that we have
foisted on us..

Well I do on both my cars. And have no intention of moving from where I
live. ;-)

Not surprising since they never really had more than just an engineering
experiment.

Reckon they have a few more problems with multipath there eh?...

Probably less given their generally better siting of their FM transmitters
- they had more than a head start on the UK in this.

It also says DAB is a success in the UK. ;-)

;-) One of the most graphic illustrations of the impact solid state made
on equipment was with pro video recorders. The original B&W Ampex V1000
was about the size of an AGA and had several bays full of glowing valves.
Some ten years later the colour version was still the same size, but no
bays. And had it still used valves, the entire studio would have been full
of bays.

Absolutely.

Colour TV really only became a realistic proposition because of transistors.
The original, all-valve, NTSC colour TV equipment was huge, expensive and
unreliable. The joke in the USA in the 1950s was that every colour TV
required a resident repairman to keep it going! Whilst the all-valve cameras
(which also used 3 bulky image-orthicon pick-up tubes) were far too big and
delicate for OB use, and were pretty unwieldy in the studio.

So although the US had colour TV from 1955, sales were stagnant until the
advent of hybrid, and later all-transistor TV receivers, in the 1960s. RCA
had to subsidise colour TV production all through the 1950s and early 1960s
because sales were minimal. By contrast once the BBC2 started colour TV in
1967 sales took off relatively quickly, and after 1970 (when BBC1 and ITV
followed suit) demand quickly outstripped supply.
