New Digital tests you can use to see if your Dab radio is Dab+ compatible ?

Sound Digital test DAB+ "Sound Waves+" | News | WorldDAB"sound-waves+"

These all working here with Dab+
The Roberts Stream 83i
Roberts Classic Dab2
Pure Evoke 2S (Ok after a software upgrade) :)

The Philips AE5200 however does not :(

The new National Multiplex is on 216.928 MHz id= SDL National

SoundWaves in Dab @ 80Kbps MP2 Mono

SoundWaves+ in Dab+ @ 32Kbps Codec AAC Stereo

Running the Dab+ transmission through my HiFi it sounds very good with that low bit rate :)

The tests are currently taking place on VHF Block 11A ahead of the commercial launch of the new Sound Digital multiplex
- also known as SDL National or Digital 2.

Still looks pretty low bit-rate to me.

Are any of them in stereo?

Yes if you read through my post you will see "Sound Waves+ in Dab+ @ 32Kbps Codec AAC Stereo"
When they play music we will see how good AAC Stereo really is.

All of the standard DAB stations will be in Mono which is a real let down. The DAB+ will also be in a low bit rate 32Kbps.
We should take a leaf out of what The Netherlands has done. Most music services are 64Kbps which does sound good. Rather than jam as much as possible in and not think of the quality. Bring back AM!!

Signal in Maidenhead is not great and I can't get a lock on the indoor aerial. The other national and local multiplexes come in OK, even the London 3 mux.

I have a rooftop aerial but the cheap DAB receiver I have doesn't have an external socket and sticking the bit of wire for an aerial into the DAB aerial outlet didn't improve any signals. Since the radio only cost £20 8 years ago I'm not complaining. I plan to get a new DAB+/Internet radio with a proper aerial connector eventually.

Ah yes I see.

So all the DAB are in mono? Pathetic.

And I know DAB+ is more efficient than DAB but is it that much better so that 32Kbps in stereo is equal to or better than 80Kbps DAB mono?

If you are using a telescopic aerial on a FM/Dab radio reduce the height of the aerial to 2 feet / 61cm for better Dab sensitivity then extend the aerial when you switch to FM,

Nearly all current BBC are in 128Kbps MP2 on normal Dab with the exception of R3 192kbps R5 64-80 kbit/s Mono,
BBC National DAB - Wikipedia, the free encyclopedia
Why DAB radio in the UK is broken, and how to fix it | TechRadar

I think only 3 commercial Dab stations are in stereo Classic FM 160Kbps,The Arrow 128Kbps & Absolute 112Kbps the rest are in 64 to 80Kbps Mono it is a joke :eek:

The BBC originally tested Dab in MP2 @ 320Kbps & thought is was fantastic then the bit rates & quality gradually came down until we ended up with a very inferior service when compared to VHF/FM Band II transmissions.

Dab+ may go the same way if the current tests are anything to go by 32Kbps in AAC is probably the same as 192Kbps in MP2 ?

As mentioned in post#4 Music channels in 64Kbps in AAC Dab+ like the dutch sounds like a better proposition maybe we can then here Music on Planet Rock in Stereo via a Dab radio :)

The Dab+ transmission here in West Essex has become distorted this afternoon I was hoping that the technical staff would have picked this up by now the other transmission is ok just the Dab+ Sound Waves that was fine yesterday on all my Dab+ radio's let's hope that it is sorted out soon as it is a poor advert for Dab+ atm :eek:

To me it's a case of too little, too late, if they did the upgrades sooner, then maybe more people would take up DAB+, but, DAB has done the damage, and it's analogue FM or internet streams for me, as those two technologies work, and sound a lot better... :)

Tnanks for the list, did a test on my Evoke 2s and receiving the test channel with existing software, so happy now.:) Must test my little Pure Move 2500 which I use in the van, this one should be OK, as it's newer than the Evoke.

Tut - they arent doing themselves any favours with some of these changes:

The new multiplex covers less of the population than D1, so Absolute 80s, Premier Christian Radio and Planet Rock will lose parts of the UK from its broadcast area, including parts of the South West, South East, East Anglia, Wales and Scotland.

Nearly all Dab radio's sold after 2012 are fitted with the relevant chip for HE-AAC v2. DAB+ so a gradual change over to Dab+ is on the cards from this year as they can get more channels using less frequency they will save a packet & hopefully some better quality radio in stereo,

I bought the Roberts Stream 83i in July 2012 & that plays the Dab+ AAC Stereo transmission ok so it must have the correct chip in it but no Dab+ logo on the set,

The Grundig that I bought in 2010 does not have the chip but I did notice that the newer version released in 2012 did have the Dab+ logo,

So this is a guide as to when the industry changed over so that all receivers sold World Wide after 2012 may meet the new specifications.
