this is radio
Worth nothing more than a £19.99 jobbie from asda. I suppose the idiots actually paying 249 are the same fools who think we need more radio than radio 4, test match special and world service.
After a slow start, digital radio might finally be getting somewhere. More people are buying DAB radios, coverage is increasing and, digital stations account for a growing share of the radio audience, according to the stats [PDF]. The BBC’s four main exclusively digital radio stations, for instance, reach a combined total of …
I bought a Tesco Value DAB about 4 years ago. It sits on my desk at work and works like a dream, albeit a slightly tinny sounding dream. Think it was a shaving under £20.
There must be loads of cheap ones. A review of the best of these would be far more useful. What sort of buffoon pays £200 for a radio?
A review of in-car DAB sets wouldn't go amiss, either.
"Worth nothing more than a £19.99 jobbie from asda."
Or a tenner on Ebay for one of those wooden Roberts radios that take two PP9s (fiver off the market, they last a couple of years) and that goes loud. I use it when making the coffee and porridge in the morning, about an hour a day. It lives on the fridge. I'll get a dab headphone radio and plug it in when FM goes off.

The Asda DAb radio is very good, it picks up signal well and sounds sharp enough.
Definatly the best radio under 50 quid and should have made an appearance.
DAB quality is still abit shakey, high quality internet radio is where it's at - there's no point in paying decent money for a radio if it can't tune into a good quality stream.
Why no Roberts Stream 83i? One of the best on the market:
I have two and they are excellent. It has the lot. DAB, FM, USB, Aux-In, WiFi, RJ45, DLNA. Can be had for £120.
I just wished they would make a larger more powerful version with a colour screen. Although the colourSTREAM wasn't quite what I had in mind.
Agreed, the 83i is great - the best radio I have used. UI is great, sound is great, the range of sources is great. Replaced a Pure Evoke 3 that crashed and corrupted its firmware too many times.
The only issue I have is how chuffing bright the blue display and power button are.
Actually, there is nothing wrong with the standard per se- it is quite well engineered. The problem is that given the fact that it uses mpeg layer 2 audio (the best codec available at the time), sound quality is quite bitrate dependant. In the UK, we broadcast at a lower bitrate for DAB than most of Eastern Europe, even, so it can sound really horrid and crunchy; certainly worse than a strong FM signal.
As for the power consumption, that is an implemetation issue. It's a bit chicken and egg, if the demand was there, then it's probably that chipset manufacturers would put a lot of more expensive R+D into it. As things are, things have come along reasonably, though not far enough. Mind, I saw one of the lab prototype recievers, and it was the size of a large crate.. now that was scary.
Really? How does that work?
An FM radio, even a stereo one, isn't really a complex beast. Some might even call it nearly trivial, if it's just an analogue radio, no RDS, no iPod dock, whatever. Even after adding digitally controlled FM tuning you can still get pretty much the same battery life as an analogue FM radio. The biggest part of the power on one of these is consumed by the audio output to drive the speaker.
A DAB radio, in contrast, has lots of work to do, by design. You still need an RF receiver and an audio output stage, just as you do in the analgue version, but in between the two you need to get from DAB (or DAB+, where was that in this review?) digitally encoded audio to something to drive the audio output stage.
That chunk of digital electronics simply isn't needed in an ordinary FM radio, and unfortunately it seems to eat a disproportionate number of watts when in use. Maybe in theory it'll be possible to reduce that stage's power consumption somewhat, but many smartphone users already know that despite their advanced low power ARM processors and expensive Lithium Ion batteries they still don't get a day between recharges, especially if they actually use them.
I looked at a Roberts DAB radio a few weeks back (doesn't matter which one). It caught my eye because suddenly the battery life numbers appeared almost usable, and I wondered what technological miracle of silicon and software design had brought this on.
Turns out the technological miracle that brought this on was giving up on HP11 ("C") size batteries and making room for a ridiculous number of HP2 ("D") size batteries. I didn't even know they still existed.
That's progress, innit.
It works by the fact that the current DAB chipsets are.. a bit pants, really. Technical term. There's a lot of stuff that could be done more power efficiently if there was money in it- custom hardware decodes of MPEG 2 with the signal processing (all the transforms and such) done in ASICs built in the latest tiny die processes and things, rather than a combination of slightly custom bits, and badly adapted and slightly more general purpose hardware.
Right now, what you have is about as elegant as Intel's "Prescott" (fat bastard) CPUs in terms of fitness for purpose. There's a sort of graph you can draw for these situations with crossing lines for off the shelf and custom-fettled top of the range silicon. The axes would be cost of initial implementation and fitness for purpose. Where you decide the sweet spot is tends to be a matter of economics rather than engineering, sadly :(
"a lot of stuff that could be done more power efficiently if there was money in it-"
I thought FPGAs were supposed to be sufficiently good/fast/cheap (pick two) these days that you could seed the market with an FPGA-based product and move to ASIC implementation to recoup the losses on the FPGA design by selling at the same end user price once the market had bought into the concept and the (cheaper per unit) ASIC implementations were ready to go?
There's plenty of FPGA/microcontroller combos to chose from, which one fits the needs here, how expensive is it?
Agreed. FM radios are cheap, sound fairly good, batteries last for ages. DAB has a bigger selection of stations but battery life is a joke, the sets are too pricey, and the sound quality- even in areas of good reception- leaves me feeling I have blocked ears due to the compression used.
If only there was a station like Radio 6 Music on FM... commercial stations all seem to play the same Radio 2 -style MOR stuff. When at home, internet radio is straightforward, but it is when driving that I do much of my listening.
Sing-sing.org is a favourite for music, http://www.abc.net.au/radionational/ a favourite for speech programs (especially their Science Show) with bog-standard MP3s available for download.
Bought a DAB/PM radio as a replacement for the kitchen. Most of the time it seems ok - but there are days when the sound "burbles" for a while. Presumably it is a reaction to some interference - aircraft flutter? Switching to the same station on FM is perfectly clear. Now we just leave it on FM.
Put quite simply we are behind the times, but no doubt will catch up.
Put quite simply don't buy a DAB radio that does not support WorldDMB Profile 1 which is needed for DAB+ when it becomes available in the UK.
I have over the years bought 3DAB radios, including ones from Pure & Roberts. They EAT batteries, when you turn them on they take quite a time to "fire up", sound quality is no better than FM, and often worse.
Please press you MP to get the UK to start catching up & adopt a better DAB standard.
In the interim internet radio is however quite good. If you haven't done so listen to Linn Radio broadcasting at 320 kbps MP3. That's better than what you pay for on iTunes and over twice the quality of DAB radio.
I'll echo the comments on price, for DAB to take off in any meaningful way the price needs to come down.
I've just bought a new DAB for the car so I can listen to 6 and sports extra but in the house I have a squeezebox which uses the Internet.
For a static radio the Internet wins you get almost endless choice in stations from across the world and you don't have to worry about signal strength.
My mum has two DAB radios in her house and she listens to both of them on FM because they sound better. Too many homes are on the limit of acceptable DAB reception and people don't want to have roof top or loft aerials for the radio.
And your Mum is counted as a DAB user in the race to kill off FM. Tell your MP that you either want DAB+ or FM but preferably both, if not both then FM is fine. The receivers are cheaper, use less energy (by design, not an implementation issue as discussed earlier) and sound better than DAB. Ask yourself, who benefits from a switch to DAB? If you or your family are not on the list, then don't support it.
DJStardust is just suffering from the limitations of a poor audio amplifier and a cheap loudspeaker in his Roberts radio - it's nothing to do with DAB or audio processing!
Compression does not affect the frequency response - as a professional broadcaster, I can tell you that compression is used to reduce the dynamic range of the programme material. It amplifies the quiet bits, and attenuates the loud bits, giving a more "average" range of levels.
The other thing that's done with compression is to increase the average level of the material, to make it sound "louder" without overmodulating the transmitter. This is common on "pop" stations - there was a "loudness war" in the USA 20 years ago, and the only result was to push listeners away from FM radio. Heavily compressed audio is fatiguing to listen to - just a few minutes can give you a nasty headache!
The original theory of DAB suggested that compression would be much less necessary. This was initially true on "quality" services like Radio 3, but ultimately found to be impractical partly because everyday ambient noise would drown out the quietest bits, and because the bit rates were progressively reduced to allow more stations into the same digital space. Quality was seriously compromised - so much so that the analogue 15 kHz rolled-off, compressed Radio 3 on FM sounds significantly better than their DAB service.
Your on about the wrong type of compression when talking about DAB. DAB is MP2 and will sound like crap even with the best amp and speakers (digital audio has come a long way since 1995). It's only really useful on a radio with small cheap speakers where you can't tell if it's crap.But it works fine for NEWS/Talk radio, or in a noisy car.
DAB+ is AAC and much better quality given the same bandwidth (iPod level) but the only way they would ever be able to switch over is to require all DAB radios sold also support DAB+ so people don't have to buy new radios... Again.
"Your on about the wrong type of compression "
No, he was specifically replying to a post about audio (dynamic range) compression. The problem with DAB specifically is the excessive lossy digital compression which is used to squash as many channels as possible into the bandwidth. This knocks the stuffing out of music and in particular destroys the stereo image because it loses phase information, not that you'd notice with two speakers 10cm apart.
It's very sad that the BBC has lost any desire for technical excellence, a few old school engineers excepted. It just wants to be a ratings whore and pump out stuff to the uncritical masses.

I was in the very meeting when the BBC Head of Engineering got on his hind legs in front of a room full of engineers and engineering project managers (I've been both) and announced with a completely straight face: "Engineering is not a core activity of the BBC".
This in a company which has led pretty much every technical innovation in broadcasting for both TV and radio for ninety years; a company which designed, developed, and defined the standards not just in the electronics but also the very grammar of TV and radio.
Still, what did they expect when the appointed the head of Channel 4 to take over as DG? He did his best to turn the BBC into a playout centre, not a broadcaster.
Neil - an old school engineer (excepted).
DAB coverage in many areas is better than FM! The receivers that are around are mostly using up the first generation receiver chipsets, and their performance is rather less than stellar! Pure and Roberts are particularly bad about this - they both wildly overestimated the number of receivers they were going to make and ordered a lot more components than they could use up. They are still building first generation radios with heavy power consumption and poor sensitivity.
Philips have recently released their new generation of DAB receiver components, and their performance is like the difference between MW and FM - these provide a perfectly listenable signal under even the most adverse conditions. The cheapest of the Philips radios outperforms almost anything else on the market, except in the amplifier and speaker department. If you use the radio as a tuner for your hi-fi, you'll be astonished by the results.
Unfortunately, OFCOM and Radio Authority politics and policy have turned DAB into a radio ghetto - we're now assailed with innumerable "ethnic" and "religious" stations, all crammed in at the expense of things that we really would want to listen to! DAB will die out as a medium if this nonsense goes on.
I bought a Denon mini hifi system (currently £180) a while back purely so I can listen to 6music. It's connected to the roof aerial, but works fine with the small lead supplied with it. Sound quality is flawless, at least for Radios 4 & 6 which are all I listen to.
Then again, I do live in London. Not sure how good it would be in a deep valley somewhere remote. But then again, FM's not so good in those places either.
Why anyone would pay £250 for some of these though is beyond me. They won't sound good enough for anything other than talk radio, which for me is available on FM.
Anecdotal, I know, but for a while I had a car that had a DAB radio in it. I got slightly better coverage (in rural Warwickshire), and what sounded to me like much better quality, by plugging in my '3' Android and using TuneIn radio (or Jango, or iPlayer).
I just can't see how the poor quality and apparently poor coverage of DAB can continue to be justified, especially given the continued complaints about portable DAB equipment is consuming batteries at a huge rate. I'm certainly never going to buy one.
... but given the poor protocol and the resulting poor performance, they then end up dialed to FM instead. That's quite a few quid wasted on a battery-eating feature that then doesn't get used.
Methinks this is quite a clear case of new technology that cannot stand on its own merits (and lo and behold, its uptake is twisted such that it doesn't need to), and so I wonder about repeat sales. Why pay the premium again, for something that didn't get used after all?
The basic problem with going digital on radio is both that FM works so splendidly, and that digital in contrast will need a few rounds of upgrades before it'll be really usable. And that means shelling out a hundred quid several times for each round and each radio you own. As a punter, I wouldn't be prepared to do that.
Then again I haven't seriously listened to the radio in ages as its compression and programming both never cease to annoy me. But even so, the digital radio set market isn't exactly driven by informed punters demanding it, and won't be for a while. I'd sooner expect to see the reverse: Punters demanding their low-power FM back, petitioning their MPs to keep the FM service because that at least works well.
I think the plan is that they'll persist with this strategy of high price functionally deficient DAB for long enough for the rest of us to have got used to streaming radio over the internet, and at that point they'll close DAB broadcasting and sell off the frequencies...
Or am I just being cynical?
I bought a terrific Tevion WiFi Internet Radio from Aldi in 2008 which I use all the time, even when sat in front of my desktop PC. It cost a mere £65 but fell to half that the following year I think, but I am not bothered as it works brilliantly and even has FM radio for when WiFi is not available. The sound quality is amazing for the size of the unit and its speakers; full, rounded non-case vibrating bass with clear but not tinny or shrill treble. It also supports the BBC On Demand service, so you can catch up on programmes you have missed.
The downside is that it does not run on batteries but then that is understandable, considering it has a WiFi receiver which on any battery powered product is a real energy sapper. If I really needed to take it out and about, I could just take a car booster battery with a mains inverter, however I doubt I would do this and instead would buy a cheap radio or ghetto blaster for this purpose.
It seems remarkable that all of these items are so over priced. Clearly this is a list of the worst DAB's as they're all such a rip-off. The message seems to be don't buy anything from these manufacturers as they clearly over charge on all their products. Thanks for the heads up. Now I'll go look for the sub £50 DABS as none of these are worth a penny more. No wonder DAB is doing so poorly when a bunch of dodgy companies are incolved.
...........I do not understand why the Editor's Choice includes a major facility that you can only use if you own one particular brand of smartphone. That would be fair enough if we were doing a round-up of dedicated smartphone peripherals/partner equipment but we aren't. The moment you are not an owner of that particular brand the Editor's choice goes from (very) mediocre value for money to truly appalling.
because its virtually impossible to find a good quality, fm only radio for a reasonable price that doesn't look like a fisher price toy. also it must not be tiny so the noise is tinny. and no to dab for eating battery.
i have a radio i bought at lidl about 12 years ago. digital tuning, world coverage, 20 squid. nice sound. i just have to buy a new aeriel for it every couple of years or so when i knock the old one off.
other than that i use my ipad and wifi.
DAB can go piss in a bin.
Which is never ever mentioned... is that the whole transmission system is designed for use in a moving receiver. Whereas an FM network is carefully arranged so that adjacent transmitters are not on the same frequency, DAB networks require that each transmitter uses the same frequency.
From memory - it's a long time since I worked with DAB services - each data packet lasts 1ms but has an expected overlap in the time domain of 0.2ms - giving a bit rate per multiplex of something like 1500kb/s. The coding for the transmission - not the audio being transmitted - is arranged with at least two and I think three levels of error correction but the forward correction nature of this requires that you get at least fractions of a packet on subsequent packets. That's intended to happen by the vehicle moving between cells; if you're on a marginal reception location and you're only seeing one signal you're stuck with whatever error correction you can get from a single signal.
So many of the complaints about DAB are simply because it's being used in a stationary location. Admittedly, the reduction in bit rate for channels stuffing more and more crap in doesn't help the audio quality, but the burbles are purely and simply because the thing's not being used as it was designed.
The reference design - Blaupunkt was the BBC's partner, I believe - will silently switch to another channel or technology if the s/n ratio gets too high (and back, if it's clever). This behaviour is dependent on the implementation though; I don't believe that there are requirements. Blaupunkt (who no longer make DAB receivers, I think) fall from e.g. Radio 4 DAB to Radio 4 FM to 'speech' DAB/FM by default; other makers somewhat irritatingly don't drop back to FM but instead will switch from R4 to R2 - they don't seem to understand the concept of listening by preference to a station rather than a subject or broadcaster. Others will switch from one 'speech' or 'music' channel to another 'speech' or 'music' channel without regard for the broadcaster...
"Which is never ever mentioned... is that the whole transmission system is designed for use in a moving receiver."
Ah, at last I see what I'm doing wrong. I should be waltzing around the kitchen carrying the DAB radio to keep it on the move while I'm frying the black pudding. I'm glad you pointed that out.
Out here in the sticks, the few DAB radios i have come across were all tuned to FM as DAB sounded so awful.
FM degrades gracefully as signal strength goes down, DAB just degenerates into a cacophany of burbling,popping unlistenable sonic mush.
The retailers are cunts as well, they have low powered DAB transmitters in the shops, so DAB sounds much better in-store than it actually is anywhere 20ft from the store.
they have low powered DAB transmitters in the shops
No they don't. Do you have the slightest notion of how much even a basic DAB transmitter costs? As a broadcaster, I can tell you. Shops are not going to install >£50k of DAB transmitting gear just to fool mugs like you into buying DAB radios.
FM degrades gracefully as signal strength goes down
No it certainly doesn't - at least not on this planet. FM becomes progressively noisier until it starts to "chop" as the receiving aerial passes through nodes and anti-nodes. Most commercial receivers switch to mono as the signal becomes weak, only to switch back to stereo as the field strength increases. This switching is seldom inaudible....
A failing DAB signal just mutes. If your receiver allows you to hear the burbles, it's either wrongly calibrated or you've deliberately turned off the muting to give yourself something to moan about.
DAB coverage is reasonably good these days. There are still a few areas of towns and cities that are poorly served, but this improves every day. It's analogous to the early days of mobile telephony, with areas of good coverage, and other areas with little service.
Out here in the sticks,
.... There's your problem. 90% of the population of this country live in towns and cities. You're just part of a small vocal yokel minority. Move house! You probably also whine about poor internet connection.....
You don't understand what that means do you? Although weirdly you do describe it perfectly well...
Incidentally, I live in a town, on a good day I can get exactly 1 radio station on my DAB radio, on a bad day I get fewer. It is now permanently on FM because quite frankly I have better things to do than piss around with something that works worse than the thing it's supposed to replace. It's like the Swordfish and the Albacore all over again...
The big department stores certainly do have low power relays - somewhat different from broadcast transmitters - especially if the audio department is in the basement, otherwise tey'd be completely stuffed.
"A failing DAB signal just mutes. If your receiver allows you to hear the burbles, it's either wrongly calibrated or you've deliberately turned off the muting to give yourself something to moan about."
I think I'd have something to moan about either way, and with justification. I'd rather have a bit of noise than no sound at all because the receiver can't recognise enough 0s and 1s to reliably convert to analogue.
I do deliberately turn off the muting. As I listen to non-music stations while driving (mainly Radio 4 and Radio 4 Extra) I prefer to have some chance of hearing what is being said through the burbles rather than having it chop the audio right at the point of the punchline of a joke or a critical response to a well asked question.
I agree with the OP when he says that FM degrades more gracefully. In a poor reception area, I can make more sense of a poor FM signal than I can of a DAB one.
I would prefer to hear it all of course, and I find that DAB reception here in the heart of the Westcountry is diabolically bad, even close to the largest towns and cities in the region. Within 5 miles of Exeter, I can find completely dead spots where you cannot get DAB reception at all. That's not in the sticks, that should be like any suburban location.
On the subject of living out in the sticks, you can take a running jump. You are just jealous of the fresh air we breathe, the green spaces we have available on our doorsteps, and the spectacular sights that you have forgotten. Unlike the Internet where distance is a problem, radio is a medium that could and should be country wide.
"they have low powered DAB transmitters in the shops
No they don't. Do you have the slightest notion of how much even a basic DAB transmitter costs? As a broadcaster, I can tell you. Shops are not going to install >£50k of DAB transmitting gear just to fool mugs like you into buying DAB radios."
Oh ffs, I didnt mean a bloody great transmitter you wally, I ment the repeating things with a low powered transmitter repeating the dab signal coming off an antenna on the roof. It gives the customer the ilusion that reception is very good in the local area with just the radios portable antenna, when in actual fact it will probably be far worse outside the store.
This is from a which report from 2009.....
"Ofcom has granted a licensing scheme allowing electrical goods outlets, such as Currys, to install DAB signal boosters. The move is designed to improve DAB sound quality and drive flagging sales, but there is concern from industry analysts that the move contradicts the Consumer Act.
The move follows a year-long trial of DAB repeaters installed in Currys Superstores and branches of John Lewis, and now puts in place a new permanent licensing scheme available to all retailers across the UK."
So yes, they do use them........
What's the point? Last time I checked DAB radios had daft standby power requirements (5w in some cases) and are expensive compared to analogue.
But what's with the poster saying "DAB coverage is reasonably good these days"? Bull crap. .Okay so I live in a small rural town but Brackley is hardly the back-end of nowhere. I've even got a 76Mbps FTTC connection these days and am within an hour of both London and Birmingham. But according to the ukdigital checker I'm "..fairly likely to receive these stations, but may need an external aerial for best reception."
Which is all of them.
My only experience of DAB is in our car, an Audi A8. While it can sound better than FM, it is still far from CD quality which should have been the aim. When I say CAn sound better than FM, I mean some popular BBC stations only, the rest sound like way too low a bitrate and no high or low frequencies. I also think with these lower bit-rates the noise to data ratio is higher, so it bubbles mud. I would like to see mandated 256kps bitrates, even if it means fewer stations, and boosted transmitter power.
........always supposing the audio manufacturers can be arsed to produce something that connects with more phones than just the iP!@! ffs. In fact the likes of Samsung, Nokia etc should be doing that kind of thing as peripherals for their phones.
Yup and I think C4 was the only channel to ever use it. I remember once flipping my TV to C4 in the analogue days and being surprised that my TV went into 16:9. Being rather pernickety about aspect ratios I made sure that it was appropriate. Unfortunately something wasn't right somewhere because there were horizontal gaps between the lines.
Hmmm. Looks like something was def. wrong then. Perhaps my TV at the time (a Sony CRT I think) wasn't able to fix up the vertical resolution.
Update: Didn't notice this bit in the Wikipedia article:
"Most widescreen sets without any PAL-plus processing will switch the display format automatically between 4:3 and 16:9, based on the signaling bits. These sets will display only the centre 432 lines of the 4:3 image, to fill all of the 16:9 frame."
I guess my TV would be one of those units then.
Well PAL+ was popular in Germany, at least with public broadcasters. They only switched it off this year.
I remember going to a local "trade show" initiated by a local electronics store to watch one of the early regular PAL+ programmes.... they simply didn't have a set to decode it. A few years later I was actually able to see a PAL+ Laserdisk from Sony.
Modern sets don't decode PAL+, but they can decode the WSS (wide screen signaling) signal.
PAL+ kinda was a stop-gap solution to still be able to do enhanced resolution (i.e 16:9 with full line count, and improved colour decoding) on terrestrial and cable channels. Back then the long term idea was to move to the "MAC" set of standards, semi-analogue standards broadcast over satellite. The idea was to start with D2-MAC and then move to HD-MAC in the second half of the 1990s. What they didn't anticipate was the "MPEG revolution". Suddenly, thanks to MPEG1 and MPEG2 it was practicable to squeeze a TV channel into a few megabits. The DVB set of standards was created and HDTV was postponed by about a decade.
So what's left of PAL+ is wide screen signaling as well as lots of 16:9 material from the 1990s.
I picked up two DAB radio alarm clocks in the clearance aisle of my local Tesco this evening- they're Tesco's own brand cheap and cheerful models, all the way from China.
Tesco Model DAB123 (a Toblerone'esque shaped charcoal grey blob with a single speaker) came in at 5 Euro. Yes- thats the equivalent of 4 quid sterling, give or take. Sound is fine- its not stereo- but perfectly acceptable for an alarm clock radio- which is what this is, after all.
Its slightly bigger brother- model CR112DABV- stretches to stereo speakers, a pleasant easily legible backlit LED, and controls that are actually easy to use. The sound is pleasant from this one- though the enclosed headphones are shite of the highest order, and should be binned. This one weighed in at 7 Euro- about sterling £5.50 give or take.
Both are alarm clock radios- both FM/DAB receivers- and one (the CR112DABV) actually looks and sounds good.
I don't understand why people don't shop around- there's two DAB radios- albeit alarm clock radios- with a combined price tag of about a tenner........?????
The Roberts RecordR records in MP2 format presumably because it's easiest, but what good is that to man or beast? What software will play MP2 or convert it to MP3 or any usable audio format?
If you buy a domestic video recorder, be it tape, DVD, BluRay or HDD, it comes with one or more tv tuners as a matter of course. If you buy an audio recorder it virtually never comes with a radio tuner or any facilities to schedule a recording. If I use the PVR to record radio off DVB-T it's recorede in some bloated video format that takes up just as much space as video, but I can't ediit the recording. The only thing I can do is play it back in real time to an audio recorder or computer, resulting in another cycle of expansion and compression.
VLC, and pretty much anything else using similarly capable decoding libs. Next question.
Also, the "some bloated format" might well be because you're getting a whole programme stream, and you just want the elemental stream, the audio essence. The trick, if that's the case, is it demux it first.
As far as I'm concerned, currently only Pure provide both decent sound quality and affordable priced products for DAB and WiFi radio. My Pure One Elite DAB radio got retired because politics kept causing the better stations to be pushed off the limited multiplex slots; radios which also support WiFi are not affected by this and can get better quality audio streams.
Frankly anyone has to have more money than sense now to pay more than £100 for a DAB radio which does not also support WiFi radio; my old decent sound Pure One Elite was much cheaper than all of these!
The first Pure Sensia is cheaper and MUCH better than most of these at £140 (Amazon); like the newer, much more expensive revision it has amazing surround sound thanks to a class D amplifier and the side speakers, can support DAB, WiFi radio, podcasts, and UPNP streamed audio, can take a rechargeable battery, has an aux audio input which you can plug a Pure iPod dock or other device into, has an alarm and Apps including a social media and Weather. You really don't have to use the touch screen much because it has a decent remote control. Another nice touch is a mounting screw hole in the body; I've stuck mine on a large camera tripod from a discount shop.
When I was given my Panasonic DAB radio as a birthday present (still going strong btw), £75 didn't seem that bad given it was fairly new at the time. That said, I do like the look of the retro radio with the built in iPod dock :). Most people just want a basic radio, so most of the radios in this review are going to be overkill.
Are there any readers here who have had experience with DAB in Oz? It appears that it is not all that popular over here in the colonies.
I have never really ventured into it after seeing an electronics company selling a DAB return radio in the returns bin with the reason written on the ticket "Customer returned due to no DAB services in area"
Granted I live outside of a capital city...
Anyone wanting to listen to non-FM radio stations (6Music, NME, 4Extra) at home might well chose to listen on DVB-T (like what the UK calls Freeview, except without the UK-specific bits) if they have the option (obviously not all DAB stations are on FreeView).
In some countries you can apparently buy a DVB-T handheld. In fact in some countries you can apparently buy a mobile phone that includes DVB-T or its (allegedly compatible) successor DVB-H.
In the UK?
The problem with most DVB-T tuners is that you need to use the tv to select the station unless you can remember accurately what the key sequence is. Also those that record don't let you download MP3 to your computer or player although S/P-DIF is provided in some cases.
You can of course get portable DVB-T receivers (with screens) but reception is dire with the built-in aerials.
I don't really understand all this negativity. I find DAB preferable to FM and have ditched all but one of my old FM sets.
I have an Onkyo mini-system in the living room (£180), a Pure portable in the kitchen (£50) and a cool looking Sony clock radio by my bedside (£70). They all sound great.
I still use a Lidl supplied AM+FM penguin shaped, splash proof radio in the bathroom because it is so cute...
The problem, in a nutshell, is that the UK has the worst quality DAB broadcasts in the world. Too many stations crammed into too few frequencies, leading to very low bitrates. Radio 3 is about the only one that offers (marginally) acceptable bitrates. At some times of day. And no-one listens to Radio 3. Remember 128k MP3s? They were recognised as being a bit rough back in the 1990s, but they were used because you could just about download a single over a modem. You need 256k for most people to perceive music as "CD quality". 99% of DAB stations are 128k or worse, and one is 192k, IIRC.
To sum up, the first post is correct - it's not worth buying an expensive DAB radio, because the source material is dross. It's like using a Rolls-Royce for muck spreading.
Bar the Yamaha, which I think looks pretty reasonable, most of these look grotesque. Why are the designs all copied from the fifties (poorly) or the Jetsons (even worse)?
El Reg clearly has aimed for the higher budget, but still, a lot of DAB kit is overpriced. I've got a reasonable Sony XDRS16DBPMI DAB which does the job, and at £70 odd is much less than most of these. Even then though, £70 for a radio is excessive. It was a gift, probably wouldn't pay that myself. But the thought of seriously spending £300 odd notes on a radio is insane to anyone but the most affluent aficionado.
Long term, I'm not sure there's really a place for DAB. FM/AM does a perfectly good job out of the home, and at best DAB is only a decent bet at home for the non-broadband users.
To suit all budgets?
As long as they are above £100? My budget for DAB is £0, because I don't need one. And with prices that high for a good one, I don't see the tempation to save up. £100 on a radio or a weekend drinking, or a new SSD, or 12 month car tax.
Too many things are better value, so lets review £20 DAB radios next time...
Assuming mobile internet availability continues to improve, DAB will become less relevant.
TuneIn Radio is an great mobile app - works well on Android on iPod touch in the home. Instead of spending 100 pounds on these radios why not spend it on a cheap Android phone such as the Orange San Francisco or similar, download TuneIn radio from the Android market and hook up some speakers. For the same cost of many radios here, you would have a more versatile, multi-purpose device, that is portable around the home.
Also, my three year old Revo RadioStation portable WiFi/Internet/DAB/DAB+/FM radio is still going strong.
I'm looking forward to forthcoming 4G / LTE roll out this/next year and the expansion of WiFi networks such as in London. Both of these are set to improve the availability of mobile internet to support internet radio apps such as TuneIn. I can already listen to internet radio in my car and hope that the drop-outs due to lack of mobile coverage will reduce as these new mobile networks are rolled out.
Because when the government decides DAB is the dominate radio service, FM will be de-licensed and the spectrum sold off. All FM radios become junk, including the one in your car. The UK will be left with a national radio infrastructure determined to be inferior by all other European countries, who use later standards for digital radio and generally continue to support FM.
Alcatel-Lucent Enterprise is the latest networking outfit to add Wi-Fi 6E capability to its hardware, opening up access to the less congested 6GHz spectrum for business users.
The France-based company just revealed the OmniAccess Stellar 14xx series of wireless access points, which are set for availability from this September. Alcatel-Lucent Enterprise said its first Wi-Fi 6E device will be a high-end "premium" Access Point and will be followed by a mid-range product by the end of the year.
Wi-Fi 6E is compatible with the Wi-Fi 6 standard, but adds the ability to use channels in the 6GHz portion of the spectrum, a feature that will be built into the upcoming Wi-Fi 7 standard from the start. This enables users to reduce network contention, or so the argument goes, as the 6GHz portion of the spectrum is less congested with other traffic than the existing 2.4GHz and 5GHz frequencies used for Wi-Fi access.
Wi-Fi 6 and 6E are being promoted as technologies for enabling industrial automation and the Industrial Internet of Things (IIoT) thanks to features that provide more reliable communications and reduced costs compared with wired network alternatives, at least according to the Wireless Broadband Alliance (WBA).
The WBA’s Wi-Fi 6/6E for IIoT working group, led by Cisco, Deutsche Telekom, and Intel, has pulled together ideas on the future of networked devices in factories and written it all up in a “Wi-Fi 6/6E for Industrial IoT: Enabling Wi-Fi Determinism in an IoT World” manifesto.
The detailed whitepaper makes the case that wireless communications has become the preferred way to network sensors as part of IIoT deployments because it's faster and cheaper than fiber or copper infrastructure. The alliance is a collection of technology companies and service providers that work together on developing standards, coming up with certifications and guidelines, advocating for stuff that they want, and so on.
A year and a half after the debut of the $4 RP2040-powered Raspberry Pi Pico, the company is shipping a wireless-enabled version: the $6 Pico W.
The Wireless LAN market was battered by a choppy supply chain in the first quarter of 2022 and lockdowns in China are compounding the problem, according to analysis by Dell'Oro Group.
Many organizations have scheduled network upgrades, but supply is not able to keep pace with demand and backlogs are reportedly 10 to 15 times greater than they were pre-pandemic.
Several manufacturers have cited components from second and third-tier suppliers as the cause of the bottleneck, Dell'Oro said, which means that the problem may not be a shortage of Wi-Fi silicon, but rather of secondary components that are nevertheless necessary to make a complete product.
New York City this week ripped out its last municipally-owned payphones from Times Square to make room for Wi-Fi kiosks from city infrastructure project LinkNYC.
"NYC's last free-standing payphones were removed today; they'll be replaced with a Link, boosting accessibility and connectivity across the city," LinkNYC said via Twitter.
Manhattan Borough President Mark Levine said, "Truly the end of an era but also, hopefully, the start of a new one with more equity in technology access!"
AMD and Qualcomm have rolled out a joint effort that brings remote management capabilities over Wi-Fi for AMD business systems, potentially boosting their appeal for corporate IT departments.
The two companies said they were working together to improve Qualcomm's FastConnect wireless kit for AMD compute platforms based on the Ryzen chips for desktops and laptops. The starting point for this is AMD Ryzen-powered business laptops using Qualcomm's FastConnect 6900 system that delivers Wi-Fi 6 and 6E plus Bluetooth 5.3, supporting Wi-Fi connection speeds up to 3.6Gbps.
Remote management is enabled by the combination of the AMD Manageability Processor now embedded in Ryzen PRO 6000 systems and the FastConnect 6900 system, AMD and Qualcomm said, with support for the DASH client management standard developed by the Distributed Management Task Force (DMTF).
Qualcomm is sampling its Wi-Fi 7 Networking Pro Series chips aimed at throughput of more than 10Gbps for enterprise access points, gateways, and premium home routers.
The third generation of the chipmaker's Networking Pro Series platforms is set to "initiate a new era" of 10Gbps Wi-Fi, Qualcomm claimed, stating that the new portfolio is optimized for multi-user environments and low CPU utilization to power collaboration, telepresence, and metaverse applications for both home and enterprise environments.
Sampling means that the Networking Pro silicon is available to Qualcomm's OEM customers so they can develop and test the Wi-Fi 7 products that will ship to end users at some point. It isn't clear when buyers will actually be able to get their hands on kit to deploy, although Qualcomm previously said it expects to see Wi-Fi 7 products hit the market in 2023.
Businesses shouldn't wait for Wi-Fi 7 networking kit when Wi-Fi 6E can give them significant advantages today.
So says the Wi-Fi Alliance, which disputes the message coming from parts of the industry that Wi-Fi 6E will only see limited adoption because of supply chain issues that might cause buyers to hold off until Wi-Fi 7 is available. Some netizens and organizations have lately complained it can take six months, a year, or more for Wi-Fi 6E equipment they ordered to arrive.
Wi-Fi 6E builds on Wi-Fi 6, which was finalized as the 802.11ax standard in 2019, saw early products in 2020, and started to be widely adopted in 2021. Wi-Fi 6E is essentially the same, but adds the ability to use frequencies in the 6GHz portion of the wireless spectrum as well as the existing 2.4GHz and 5GHz bands. It follows moves by regulators in the US and elsewhere to open up the 6GHz spectrum for Wi-Fi use.
The Wireless Broadband Alliance (WBA) has completed testing to prepare for the deployment of WBA OpenRoaming, a federation service built to give seamless access to Wi-Fi hotspots across Europe's municipal networks.
WBA OpenRoaming, described as a "Wi-Fi roaming standard," is intended to provide users with roaming access to Wi-Fi hotspots without having to keep registering with different operators or enter login credentials every time.
The WBA also claims that OpenRoaming offers enterprise-level security and protects user privacy while complying with European GDPR policies when roaming between Wi-Fi networks.
Cisco on Tuesday issued a critical security advisory for its Wireless LAN Controller (WLC), used in various Cisco products to manage wireless networks.
A vulnerability in the software's authentication code (bug type CWE-303) could allow an unauthenticated remote attacker to bypass authentication controls and login to the device via its management interface.
"This vulnerability is due to the improper implementation of the password validation algorithm," Cisco's advisory says. "An attacker could exploit this vulnerability by logging in to an affected device with crafted credentials.
