Spend more money on buying new radios at home and converting the car to listen to the same stuff? So i have more choice - but when I listen to no more than two radio stations the vast majority of the time (Radio 4 and ClassicFM) and thatm most of my listening is done in the car I relly start to question the benefit. FM is sometimes a little crackly - but my car is no hi-fi studio so I'm unable to appreciate the finer nuances of each broadcast.
DAB is a technology that has been shown to have problems - why is this inferior and more complex technology being foisted upon us.
However if they had something like Dave on DAB then that may be worth looking at (or listening to, at least)

Here I am in Scotland, less than 30 miles from Edinburgh. I can get DAB - I can get BBC Radios 1/2/3/4/5/6/7/1Xtra/Asian Network and World Service. However I can't get BBC Radio Scotland - or in fact any commercial stations - what a great selling point that is!
Even when I do get it, it's awful sound quality - I'm old enough that I can remember when FM stereo used to be turned on and off by the BBC - DAB is mostly a return to that world with additional warble (the warble that Radio 3 used to give when you had too strong a signal). It eats batteries on a portable receiver about 3 times faster than an analogue set so presumably something similar is true of it's mains consumption.
So to recap - reduction in choice, quality and energy efficiency - wow! where do I sign up?

DAB as standard for cars #
Posted Tuesday 24th June 2008 15:23 GMT

The key to this would be getting DAB as standard in cars, as let's face it, unless it starts to happen in cars there's no way the general public will allow FM to be switched off. I certainly wouldn't be happy about being forced to upgrade my car stereo right now, just for the same of listening to the one radio station I use in the car. I'd give up on radio and just stick to my iPod probably unless Vauxhall start shipping the radio's dirt cheap after market :)

So who is going to pay to have the highly integrated proprietary manufacturer's head unit in my car upgraded to DAB when they switch analogue FM off? I won't be, so I guess I wont be listening to any radio whatsoever after that, as that's the only time I do at the moment. The 6 disc CD changer might get a bit more use, or perhaps I'll just enjoy the sound of the engine instead, its often better.

But.. #
Posted Tuesday 24th June 2008 15:23 GMT

DAB IS shite - coverage is crap and unless you've got a good signal you get nothing. At least with FM you can get a signal even if its noisy. Given that some commercial "national" radio stations can't even get nationwide FM coverage sorted out (Classic FM being a prime example... but then again they seem to be DAB mad so I guess giving people shite FM reception with excess audio compression is just them trying to force us all to DAB) what hope in hell do we have getting DAB sorted out.
Of course the problem with cars is that manufacturers went down the integrated system route and now its not practical to replace a radio in car because you loose all the things like the display in the dash board and the use of the controls on the steering wheel.
Even if there were units that worked when I plugged them into my Saab 93 (and integrated with the Saab CD multichanger and the third party Ipod controller) why should I be forced to spend a lot of money upgrading because the government want to get their greedy little paws on the revenue from selling off the old FM spectrum.

"FM should be switched off by 2020" good grief - why wait so long? It's this procrastination that's leaving the public dissinterested. Announce the complete analogue switch off in 2012, change to DAB+, get the car manufacturers on board and make sure the reception coverage is up to snuff and watch the public move over in droves. This procrastination drives me nuts. Sure there will be some backlash (not least from those with non upgradeable DAB radio's - which includes me) but that's just tought titty. Get on with it!

My DAB radio only picks up Radio 1 (I had it before recently moving house). So improving the coverage would be good for starters. FM works beautifully.
I suspect that by 2020 everyone will have gone to internet radio (in whatever form it is by then) as the current crop of Wifi radios are great and can't be far from appealing to the masses! (Rather than just gadget freaks like me!)

Posted Tuesday 24th June 2008 15:28 GMT

A few years back, I bought a (good) DAB radio to listen to on my way to/from work on the bus. Took me all of two minutes to realise that DAB is not at all good on the move!
Every now and again, I get the thing back out and give it another shot - every time, I've put the iPod on before I'm even two minutes up the road!
OK, so perhaps living in the Granite City has something to do with the piss-poor reception too - but still, if DAB won't work on the move in all environments and all weather conditions, and do it at least as well as FM then shutting down FM will effectively shut down radio... Bad plan folks!

Experience digital sound quality, the DAB promos shouted.
Well, if by quality they meant an over compressed media stream using a lossy format, then they were correct.
With many radio stations storing their music in already compressed form on hard drive libraries, and then re-compressing during broadcast for DAB, the sound quality quickly drops to terrible levels.
One reason I'm in no hurry to get a DAB player.

Missing the blindingly obvious #
Posted Tuesday 24th June 2008 15:55 GMT

There are many simple reasons that don't require a degree to figure out.
1) The units are too expensive. The cheapest DAB units start at fifty quid. You can buy a regular radio for under a tenner.
2) The average person doesn't want the extra channels. We like BBC and local radio. And we can get the regular channels on our good ol' analogue radio.
3) Most people who might want the extra channels can listen via the internet or their TV. They don't need to spend fifty quid on a radio.
The only way you can get people to switch is to knock the price down by at least half. You can't tell me that the manufacturing costs of DAB radios massively exceeds that of analogue radios. It's not like you have iridium-plated nanoprocessors in the darned things.

OK, TV I could take, but this timescale is nonsense #
Posted Tuesday 24th June 2008 15:55 GMT

I could just about stomach the change to Digital Terrestrial TV, but irritatingly my really not very old Panasonic hard disk/DVD recorders (DMR-E85H) with integrated analogue tuners will be effectively obsolete and no amount of messing about with external digiboxes will make it user friendly so the final environmental cost of the switchover in my household will be three "portables" (in places like the workshop), two still working VCRs, a DVD recorder, the two Panasonics mentioned above, two TV/VCR combis, and half the functionality on the TV/PC monitor combi in the kitchen, plus the 12v unit thats handy in the car or when either the power goes out or we do. I'll discount my handheld as its Argos-bought rubbish.
We have one Panasonic TV with both types of tuner and one other TV with a spare Scart so at least I can make that work reasonably, so thats a lot less TV viewing we'll be doing (and we are fairly discriminating even now), and no recording/timeshifting under current plans, even if there was anything much on the other channels. - I always thought they should keep one or two analogue channels, perhaps a "Best of BBC" and a "Best of the Rest" for those of us just wanting some background stuff on our old sets, until realistically there are so few of these around no-one will notice. I would willingly give up all the digital shopping channels to keep enough airspace for these two
Changing to radio will be worse for the environment and the pocket. Much worse. I have a DAB, and I quite like BBC7, for all the predictable reasons so I'm not greatly opposed in principle. We also have a pocket sized digital unit but battery consumption (we use rechargeables) is very high. The cars and motorbike (yes, really) all have manufacturer specific radios, so its not like I can pop down to Halfords and slot in something DIN sized when these "go dark". It may be a long way off but I like stuff to last and dont intend my vehicles to be landfill or scrap anytime soon, although I concede that the lack of oil in 10 years may affect my transport more than not being able to listen to BBCR2/R4 whilst commuting. I have loads of small and not-so-small radios scattered about the house so we can listen independently whilst doing other things. Its good for the brain and our sanity. So those are all going in the bin as well then it seems.
Going for just a European standard for the benefit of car manufacturers is no good. What about the people on the edge of Europe who like to listen to countries over the border that will still be on old tech? Cars being the mobile things they are this is a much bigger issue than TV. I made enquiries about FM switchoff a year or so ago and was refused answers, probably as I asked the question at the same time as highlighting the problems.
I agree the change is needed, but in both cases there should be a long term "lingering" service for those with old tech that they don't wish to or (for many) can't afford to replace until they really have to, and to reduce the impact of cutting short the "whole life" environmental costs for those of us not hung up on having the very latest kit all the time. Certainly the two year switchover I have seen mentioned in other media today is ludicrous. And I haven't even started on the concerns that small broadcasters would have, as well as the other services (all your traffic-master links on your GPS will fail, they go over FM, so thats more kit for the chop).
What gets me most is someone will dress the change up as being green when in fact it is only the taxpayer subsidising equipment manufacturers, and loads of kit in otherwise fine working order being condemned by the onward march of "progress". Unfortunately I can't see someone at least sending working stuff to developing countries as at least they have done with with old PCs

What about the Quality ? #
Posted Tuesday 24th June 2008 15:55 GMT
One subject that is very rarely discussed is the quality of DAB Radio, and I have found that as more and more stations eat up the bandwidth on DAB Radio the bit rate goes down and down along with the quality. The bit rate of all but a few stations (Radio 3/4) is 128k and below and given you can most of the stations at home on Freeview at an average bit rate of 192k I can't see why anyone would spend money on a DAB Radio for the home.

"Next will come massive promotion of how great digital radio is."
I think that should have read "Next will come massive promotion of how great digital radio could be."
Having been one of the 'early adopters' of digital radio I was distraught to discover the reduction in audio quality that moving to digital provided. Low bit rates that are unacceptable to anyone interested in music are the primary factor in my moving back (up?) to analogue FM. When you factor in the inability of a digital car radio to maintain signal coverage over even a short journey together with the lack of a European wide standard (or rather, at the moment, too many standards), this is a hopeless proposition.
Unless we all move to the superior standard used in Europe then they are simply flogging a dead horse.

As a regular visitor to the US I have to say that XM radio isn't that good. Yes its good when it works but get anything over your head (like power lines) and the reception just goes out of the window which doesn't work too well in cities, and of course you have to pay for it - which does mean that you dont get those stupid annoying adverts.
I think the "crank up the power" attitude of the FM radio stations in the US is the way to go : 100,000 watts of transmitter power seems to do quite well for WTOS-105FM in Maine, and their music taste is good too.

What lessons were learned from the transition from MW and LW broadcasting to FM? How could these be applied to the transition from FM to DAB, and what is *not* applicable?

DAB in cars #
Posted Tuesday 24th June 2008 16:07 GMT
The reason FM in cars is still holding strong is that most people are happy with the quality of FM radio - DAB doesn't add that much that the road / tyre / engine noise wouldn't take away. If we want crystal-clear sound, we tend to think that sitting in a metal box hurtling over potholes isn't the best way to achieve that.
Me? I still listen to sport on the medium wave, which is fine for my purposes. If I want better sound quality, I slap a CD in. Then I get to choose what songs get played, and I can supply my own irritating voice-over.

Must have spoken to the FCC in the US #
Posted Tuesday 24th June 2008 16:07 GMT
This fools must have spoken to the FCC here in the US. By Feb 2009, traditional analogue free to air TV will vanish to be replaced by digital TV. Sure it will enable HD broadcasts and all that jazz, but it's being handled in something of a almost confused, and yet draconian manner. It's not clear why the old broadcast system has to die so quickly, but it's pretty clear that you better get yourself a digital TV decoder if your old analog set wants to continue displaying anything other than snow.
I can't see the point of adopting such an approach to DAB. Quite apart from anything else, if you're going to kill off part of 'radio' to replace it with DAB, why choose FM? FM is comparatively short range. Wouldn't it be better to kill off the Long/Medium wave part of radio and supplant it with DAB? Longer range and all that. The error correction possible in DAB technology would easily cope with the slightly flaky MW/LW spectrum's tendancy to have interference....
Why do away with any of it? Oh, wait, yes, I see now. Sales of DAB licenses to broadcasters, and possibly even licences to own a DAB set? Ah yes, it's true, the accountants are running the asylum.

I guess a lot of the stand-alone units will be replaced by then or you can pay for and replace the external TMC-FM receiver (on TomToms at least) - no idea what one would do with an integrated car set.

So the proud tradition of broadcasting is to be reduced to:

* Which might not matter, because they compress (or, in old money, distort) all the radio stations except R3
* And the source sound quality is poor because the craftsmanship of sound engineering has been squandered in a fit out Birtist outsourcing
* But you wouldn't be able to hear it anyway because the kiddie producers add background music which is too loud

Do you honestly think WiFI radio is any better? #
Posted Tuesday 24th June 2008 16:22 GMT
WiFI radio is far worse than DAB on a bad day.
Streams can easily slip to 30-40 Kbs and sound truley dreadful.
Techies on this site may well enjoy the challenge of getting their WiFi radio to talk to their wireless net but can you really imanging giving one to your aunt Doris and not expect to be on the phone for ours talking her through it?
FM and DAB radio is free to recieve and of course internet radio takes up bandwidth. If you find a good, high quality stream, it will take up even more bandwidth... which you ulitmately have to pay for.
You might want to say that the choice is better, well yes having 18,000 station might be a bit more choice than is useful to anyone. To add to that, almost all US stations have GeoIP blocking in place to avoid paying higher fees to their music industry so you can't listen to them anyway. As the industry get more regulated this will be the case all over the world.
I have 4 DABs at home and don't have a problem with any of them. The choice of stations is great and the quality is fine. MP2 it may well be, but in the kitchen in the morning it is perfect.
Please don't forget just how lossy AAC is compared to a proper 44.1 Khz recording. For all those who shun DAB in favour of their iPod: open your ears and go to some live music to hear it properly.

"and unless you've got a good signal you get nothing"
Not always the case. Here in my location in the hills 14 miles from Manchester the BBC stations and one of the other multiplexes come from around the Picadilly area I believe. These are recieved at 100 percent signal strength.
However the regional stations are from Winter Hill, Bolton. Due to all the hills in the way the signal is very weak at times but still works so your comment about needing a god signal is not really valid,
I see the digital cliff as a good thing. For example I can listen to Choice on MXR Northwest without any burble on a very weak signal. However a little drop in signal strength it does all got to pot as you say.
Imagine listening to an FM station at 1 /10th of its maximum strength. It would be fuzzing and hissing all over and probably dropping into Mono.
However I do agree about the less than perfect sound quality. Not the CD quality we were promised and agreed moving at high speeds on trains for instance its useless. Have the unit still with a good tuner and DAB will work on next to no signal which is great for here.

These are classic stand-alone units, not the hook up to the hi-fi (with obligatory Jesus cable, see Register passim) type and then bitch about the quality.
I like the numbers of channels, I like the speed of tuning, I have no problems with the quality at all.
I haven't listed to FM for years now, all the stations I want are on DAB and I'm happy with that.
So as far as I'm concerned go BBC, turn that FM off and go DAB.

Worse, the DAB encryption is low quality (per bandwidth) and coded into hardware/licensing. Upgrading the encryption is not possible and the DAB encode was known at the time they rolled it out to be inferior.
DAB+ has a more effective encode and so uses spectrum more efficiently.
So DAB+ uses a different coding and ALL your DAB radios are no longer working.
And no way to upgrade.

DAB is like ITV Digital, cr*p. It's over compressed and doesn't offer any real benefits over analogue FM transmissions. When it cam out it wasn't such a bad idea but now it's obsolete and they would be a lot better offering a decent DAB2 standard and turning both FM and DAB off asap.
DVB only took off because the boxes were cheap and the Beeb took over from ITV digital. Everyone knows you need a digi box. Even with DVB now that HD is on the horizon the technology is going to need an upgrade. DAB was too compressed, cam out too expensive, sounds worse than FM and has been around too long and has clearly been over taken.

It will go the way of ISDN ... ( It Still Does Nothing .. )
The music is overcompressed with a lot of loss.
If you drive 40 miles you lose the station. The DAB transmitters are all short range.
The reception is all or nothing , and line of sight is much more important with DAB than with FM. Drive in an area with tall buildings and kiss the reception goodbye.
Why don't we use satellite ?
Look at the US : XM and Sirius are hugely popular. Reception guaranteed , hundreds of channels and with a few satellites they cover a CONTINENT !. Just use one of the ASTRA birds already up there to blast the signal over one of its unused transponders. Instant coverage of the whole of europe.

The issues are simple.... #
Posted Tuesday 24th June 2008 17:38 GMT

1) We can easily switch off FM and have a digital radio service.
BUT....the replacement, whether it is the current DAB system or a better (DAB+?) system, must be properly thought through....as things stand right now, over 10 years AFTER the launch of DAB, is that some area's still don't have ANY reception.
This needs to change.....we need 100% coverage of digital radio, BEFORE any decision to shut down FM.
2) Currently, the DAB frequencies are allocated by OFCOM, who have chosen to only licence a few....
So, to kick off then, we need a wider range of frequencies (ie multiplexes) to be licensed immediately, so that existing DAB stations can broadcast at higher bit rates and hence we can have quality digital radio (coz DAB at 192kb sounds pretty good!), rather than pi**-poor 128 kb (or less), which sounds awful.
3) With more multiplexes available, every local BBC radio station can be heard of DAB, in their local area.
Get these up and running and then local commercial operators will move across from FM, once more people listen to the BBC on DAB.
The driving force for uptake of DAB has always been the BBC, so get them behind on a local basis and the rest will follow....
4) The entire DAB network mainly uses the old 405 TV transmitters....so, we need OFCOM to pressure Arqiva to ensure that each of these, including the relays, are all fully operational and running at the right power levels to provide 100% coverage as in point 1).
Only after all the above are sorted, should we think about switching off FM.....but as you can see, to do the above wouldn't take long as the infrastructure is already there....!
Job done.

WiFI radio is far worse than DAB on a bad day.
Streams can easily slip to 30-40 Kbs and sound truley dreadful.

Ignoring that WiFi is really irrelevant, as you mean Internet based streams...
...they don't "drop" when I listen to them, maybe you need a better ISP? Certainly if the radio station isn't pulling a fast one on bandwidth, there's something wrong if you can't maintain a 128kbps or better stream.

Techies on this site may well enjoy the challenge of getting their WiFi radio to talk to their wireless net but can you really imanging giving one to your aunt Doris and not expect to be on the phone for ours talking her through it?

Yes, and it didn't take hours. I know 1 person with DAB, 6 with those standalone Wireless Radio jobbies.

Please don't forget just how lossy AAC is compared to a proper 44.1 Khz recording. For all those who shun DAB in favour of their iPod: open your ears and go to some live music to hear it properly.

Which is why I haven't used one of Apples evil creations.
