  1. A week ago I bought a Phillips pocket DAB radio DA1103/05, £39 from a Comet
    store in London. It seemed quite good to me, and is small and neat, but
    everytime I did a 'local' scan of the stations; it *wiped off* all the
    stations that I had previously *preset*. I quite often need to do a scan
    since the reception quality is very different between the front and the rear
    of my house.

    I took it back to Comet, the girl there became very 'fish' faced, but gave
    me another one. I said i would like to test it and she said you cannot pick
    up any stations in this store. So I went to the next door shop where I
    could sit down, and found that this replacement set had exactly the same

    I took it back and she then tried to set up the presets herself, at the
    counter in the store where we were before. ( Making a lie of what she said
    about not having reception in the store). But she didn't know how to do it
    and declined my offer of showing her how to. Any way even more fish faced,
    she then gave me a refund for the £39.

    I later rang Phillips technical help and they said they had not encountered
    this particular problem with this radio and would ring me back. They
    didn't, so I rang them again, but I got the distinct impression that they
    really were not that interested in any of this, and got no further ahead.

    Thinking I would buy another one, I rang the nearest John Lewis Store; but
    it looks like although they do sell Phillips radios they do not sell this
    'particular' pocket model. The model is DA1103/5 and the software version on
    it is: V.1.3.2. I think it might be a very 'recent' version since it
    offers 30 presets as opposed to the generally advertised 20 presets

    Since John Lewis said they could not even 'order' me one of these radios,
    i'm wondering if they have been having trouble with them?

    So my quandry now is whether to try to locate another one, or switch to
    another pocket DAB radio? Is there another pocket radio that people would
    recommend; or should I best pursue another one of these Phillips? Thanks
    for any advice.

    Rescaning in the same locality is pointless. Take it to a local point of good
    reception, and scan there. For instance all BBC national radio stations
    operate on exactly the same frequency in the UK in what's called an SFN, so
    rescanning will bring back exactly the same transmission if receivable.

    The only time you need to rescan a DAB receiver in the UK, is to receive new
    local stations when you enter a new area, or to receive a newly launched station.

    Losing pre-sets on scanning may be a 'feature' of that particular model -
    which seems remarkably cheap for the features claimed.

    It wouldn't have occurred to me to re-scan in an attempt to overcome poor
    reception; just go to a spot where the reception is as good as you can get
    in your area (a local park, perhaps?) and scan - thereafter, if you can't
    receive a particular station in a particular spot re-scanning isn't going
    to help. I've never found it necessary to re-scan even when going to a
    different part of the country, as far as national stations are concerned.

    Pocket receivers often have rather poor aerials and don't work well
    indoors or where the signal is weak - which DAB is in some places.

    Some DAB receivers offer two sorts of scan: one to re-create the entire
    station list, the other merely to add any new stations (and possibly
    remove any no longer found). The latter sort of scan shouldn't upset your
    pre-sets, but the former might well do so - although I agree that it would
    be better not to if the pre-set stations are found by the new scan.

    My only experience of pocket DAB receivers is a Sony XDR-M1 I've had for a
    few years, which works well. I've also had good experience with Roberts
    portables, although I haven't tried their pocket model.

    it...........*Local Scan*.

    Different transmitters can, and do, carry different 'local' stations as
    well as providing the same 'national' stations as each other. Like VHF/FM
    analogue stations, each transmitter has a very limited range - a few tens
    of miles at most, usually - so DAB stations can be very 'local', even if
    the transmitter shares the same radio frequency as other more powerful
    neighbours. DAB is very different from analogue.

    I've noticed that say, if you change areas you can lose presets on many dab
    radios. Its a difficult one, as they are not really lying about it, they are
    just not saying the software has a drawback if you rescan you have to re
    store the presets.

    I was thinking when you first said it was a pocket model that there have
    been poor reception problems with dab. Most people are familiar with the
    boiling mud effect you can get if signal is low, but some sets do rescan if
    they get very low signals that this can confuse the heck out of users.

    Dab is a bit of a flop for quality and coverage in my view.

    I'm not sure if the DA1103/05 has this feature but my Zenith DTT901
    (American HDTV receiver) has both an "Auto Tune" and an "EZ add" scan

    Auto Tune does what you described in wiping the presets clean and setting
    all channels receivable in that scan.

    EZ add leaves the presets as they are and adds to them channels received in
    that scan.

    For my unit I can scan channels with my aerial facing west (Baltimore) and
    add channels while its facing north (Philadelphia).

    Not all receivers do this (my Sylvania doesn't) so there may be a DAB out
    there with this handy feature.

    Good luck. ;-)

    I read somewhere that some Scandinavian countries have scrapped DAB because
    reception is so unreliable.

    Bad designs like this seem to be normal these days. If it works at
    all, they consider it finished and move on to the next product. I
    doubt Philips will care since they probably had nothing to do with the
    actual design of the radio.

    Not true. Old DAB is too inefficient.
    I think DAB+ will be the future here.

    As I understand it, transmitters can carry both DAB and DAB+, and some
    receivers can cope with both. But there is now a significant number of
    receivers which can only manage 'original' DAB, and broadcasters are
    likely to be reluctant to broadcast their content using both standards at
    once, or to broadcast only in DAB+ while few people can listen to it.
    Listers would be pretty peeved if required to scrap all the new DAB
    receivers we've bought by the million over the last five years or so.

    While 'audiophiles' might be prepared to buy new equipment to get 'better'
    sound reproduction, most people just want something 'good enough' - which
    DAB manifestly is. I'm listening to Radio 4 as I type: "Varied Speech" at
    "128kbps Stereo" which sounds fine to me (on a Roberts MP23). Radio 3
    probably justifies the 192kbps Stereo it gets, but most stations are Mono
    and many only get 80kbps and don't seem any the worse for it. I just
    don't expect, or even want, a 'concert hall experience' in my kitchen or
    bedroom, or even the living-room, and certainly not in the car.

    BBC podcasts and streams all seem to be at 64kbps.

    We would never start using the old DAB in Sweden and Finland,
    that's for sure. DAB+ or something more modern is the future.

  14. WorldDMB are liars.

    For example, if you go to the WorldDMB home page and hover your mouse
    over the word "DAB+", it says that the system is backwardly compatible
    with DAB. But the opposite is in fact true, and I've asked WorldDMB to
    tell the truth and correct their website, but they've done nothing.

    The President of WorldDMB is Quetin Howard, the ex-chief exec (before
    being sacked) of Digital One, who lied on BBC TV:

    and he basically lies whenever he feels like it.

    Since 1996 we have testing DAB here in Sweden and we don't like it.
    The same in Finland. Finland closed down DAB completely.
    Old DAB is too inefficient.

  16. Hahahahahahhahahahahahahhaaha. Consumer resistance? You're having a

    The VAST MAJORITY of people WANT DAB+ to be used once they know what
    it is and what it provides.

    The adoption of DAB was the most incompetent technical
    decision ever made in the history of UK broadcasting:

  17. There will be a slow migration over to DAB+. All "DAB" receivers are
    gonig to support DAB+ and DMB-A soon.

    On a portable radio maybe - on *anything* better you've got to be deaf
    to think that.

    Funny how you've mentioned the ONLY two stations that are using
    reasonable bit rates on DAB - R4 at 128k is reasonable because speech
    is far easier to encode than music.

    That's both factually wrong and it's plainly idiotic to suggest that
    music should be broadcast in mono.

    Who the hell are you to say that just because you don't want something
    better than others should be denied it?

    BBC music podcasts are now 128 kbps MP3, the BBC's listen again MP3
    streams are 128 kbps, 192 kbps (R3) adn 80 kbps for mono stations. The
    live streams will start using higher bit rates in the next few weeks.

    Why don't you check your facts first?

    Steve - - Digital Radio News & Info

    The adoption of DAB was the most incompetent technical
    decision ever made in the history of UK broadcasting:

  18. DAB+ is 2-3 times cheaper to transmit per station than DAB. That's one
    of the attractions to the commercial broadcasters. DAB+ is definitely
    going to happen, and it'll happen sooner than you think.

    I saw a quote that sums up the situatino with DAB+ pretty well:

    (wording from memory)
    "people overestimate how much progress can be made in 1 year, but they
    underestimate how much progress can be made in 10 years"

    That's spot on where DAB+ is concerned. There will be loads of DAB+
    stations in 5 years' time.

    Now you're lying, because I told you what the score was in the early
    days, so repeating this is lying.

    You're also an R4 listener though, and you admitted that you don't
    listen to the pop music statinos or similar, which is wehre you get
    the shit audio quality.

    Basically, both of you two are just extremely selfish people.

    They screwed up in the first place:

    So don't try to suggest that we couldn't have had good audio quality,
    because we DEFINITELY could have had it.

    The BBC is already using 128 kbps - and even 192 kbps for R3 - for a
    lot of its Internet stuff now.

    The adoption of DAB was the most incompetent technical
    decision ever made in the history of UK broadcasting:

  19. Plowman, DAB is DEAD in Sweden and Finland - the transmitters were
    even switched off in Finland, and most of the transmitters were
    switched off in Sweden as well when the government refused to fund it.

    Now that DAB+ is available adn there's receivers and ALL DAB receivers
    are going to include support for DAB+ in the near future, there's no
    way that any country that's considering what system to use would use
    DAB. End of story.
