    Personally, I would have thought it was an improvement when a political
    discussion is on!

    Places near the edge of the UK suffer from continental interference
    after dark.
    You can get rid of it by adding a fancy aerial at a cost almost equal to
    the DAB radio itself (or more for a cheap DAB radio). I find the effect
    on talk radio intolerable too they sound like the subterraneans off
    Stingray like they are gargling whilst trying to read the news.

    DAB was a good idea badly implemented not enough bitrate. These days I
    use internet radio where the broadcast quality of Radio 3 is excellent.

    It is Radio 4 which includes TMS in its program schedules.

    Possibly because 198 is Radio 4 UK.
    Perfectly strong and clear in SW England.
    Beyond the reach of the Channel Is VHF, it's good for
    me down to at least Châteauroux. It's usefullness is limited
    in the summer afternoon it carries a ball-by-ball commentary
    on that boring English pastime.
    What sort of noise is masking it?

    Solved by purchasing a custom cable.

    Fibre has not dropped out at all apart from twice
    on the first day.

    However, my downloads and uploads to the cloud take
    just as long as before. I would have expected cloud
    uploads to be faster, although programme downloads
    probably suffer from bottlenecks somewhere else along
    the route. Or perhaps there's something I've missed
    doing in the router setup? The speed tests are fine.

    I assume, fear even, that when they no longer fit
    VHF radios in cars, we'll lose LW and MW as well.
    I'm changing my car next year and the one I fancy has
    DAB radio fitted. :eek:(

    Get hold of an old Band III TV aerial, clean it up,
    put it on the chimney and away you go.

    Plenty of these unused and hanging off chimneys since
    TV left that band. Some of them with quite reasonable gain.

    Yes, although many were only tuned for a particular Band III channel.
    DAB uses blocks in the old Chs 10, 11 and 12. So an aerial from say
    the London or Granada regions, Ch 9 in old money, may not perform too
    well for BBC DAB on 12B. Better than a bit of wire stuffed in the back

    You don't want too much directionality though, DAB relies on being able
    to sum transmissions from several transmitters, so actually you're
    better off with a single dipole vertically mounted to give omni
    directional response. Also, you run the risk with a directional aerial
    of pulling in a distant DAB transmitter, if more than 78km away, the
    signals arrive too late (with reference to closer transmitters) and the
    addition of data leads to a destructive rather than constructive effect
    on reception .

    All the stations will be available on DAB. My son has DAB in his new
    motor and he loves it. Reception is way better esp compared to LW and MW

    Indeed. I'd forgotten about the channel
    groupings they came in. That was some time ago!
    Learn somthing new every day. I'll stick to my
    telescopic on the set.

    No doubt, but I was again thinking about
    motoring abroad. Although DAB'll work on the
    Continent, the UK channels won't be available.

    I wouldn't miss MW/LW here in UK.

    Don't they now use DAB+, and many UK radios are still only DAB - and
    hence incompatible?
    Ian Jackson, Aug 10, 2014
  14. That's unlikely to happen if the aerial is actually pointing at the
    nearest transmitter. So directional aerials can be of use for DAB.

    And there's a more distant one receivable directly behind ?

    There's a BBC paper somewhere suggesting that just that problem
    exists for some in East Anglia (thanks ironically to the flat terrain)

    Really? Which DAB multiplex carries Breeze Basingstoke, or Breeze Newbury.
    Which one carries Eagle Extra, or Reading 107?

    DAB will not replace VHF FM transmissions.

  17. I wonder how long it will be before we all, indirectly and without
    realising it perhaps, miss the opportunity they all provide for young
    people to learn first hand how radio works?

    My first foray into electronics was via the construction of "crystal",
    or passive component radio sets. It was seeing an explanation in a
    book that included a circuit diagram with only three main components
    that made me realise I could do more than just read about this;
    perhaps I could actually make one. I already had a high impedance
    earphone from something else, so the only special components I needed
    were a coil, a capacitor and a diode - just three things, and all the
    rest was wire.

    And it did work. Sometimes it's possible to be inspired by a book, but
    there's nothing like the inspirational boost that comes from doing
    something for yourself and realising that you've achieved something
    real and meaningful.

    Goodness knows where future generations of electronic engineers are
    going to come from, or what's going to inspire them. Almost everything
    electronic nowadays is sealed and incomprehensible, full of thousands
    of microscopic parts that can only be made in factories, way beyond
    table-top construction using handfuls of components you could make
    yourself. It'll still be possible to wind a coil on the cardboard tube
    from a toilet roll, and to make a variable capacitor from two sheets
    of baking foil and one of paper, but when there are no more
    transmissions to receive, there'll be no point in bothering to do any
    more than just read about it.

    Reading 107, (now re-branded as Jack FM Berks) is on the Hants/Berks
    local mux

    Eagle Extra, dunno, is that Eagle 3 ? If so, Surrey Mux

    The Breezes are not on DAB though, as you say
    Mark Carver, Aug 11, 2014

    Paul Cummins Guest

    No, Eagle Extra is "Eagle 2" of you consider Eagle and Eagle 3.
    And they can't be, because DAB isn't Local enough.
