The Roberts Sports DAB RD14, £100, is a dab/fm radio, and, on dab stations, has extra info such as sports scoresSo what is DAB? is it better than FM, and can anyone really tell the difference?
Well, Digital Audio Broadcasting is the technology that allows stations to broadcast radio digitally, in the same way that Freeview broadcasts digital television. One advantage is that lots more stations can be broadcast, but take up smaller frequency space.
With DAB, you never need to remember a station's frequency as the display on the radio shows the station names alphabetically.
There are lots of extra digital-only stations, which an old-style analogue radio can't receive, such as BBC 6 Music, Talksport and some extra local and niche music stations.
The signal will either be brilliantly crisp and clear or it won't be there at all. Only rarely do you hear anything in between: a rough DAB signal sounds like a Dalek gargling.
Critics are divided as to sound quality, though most admit that if you can find a strong FM signal, it will sound better than DAB as most DAB stations transmit using limited bandwidth.
Some new models include a new standard, called DAB+, but there are no UK transmissions yet, so it's not something you need worry about.
As the DAB signal isn't perfect, it's worth considering a radio with an FM tuner, too. if choice is important to you, then DAB will give you a greater range of stations to tune into - and tuning digitally is easier and more precise than analogue tuning.
Before you buy your radio, though, check that DAB is available in your area - go to ukdigitalradio.com and enter your postcode.
Some DAB radios, though not the pocket models here, include a recording option so you can pause the radio if the phone rings or save programmes to memory cards like those in a digital camera.
