WHATS IS DAB?
DAB radio will change the way that people listen to radio over the next few years. You
will probably not be aware that digital radio will become mandator y in the future as the
terrestrial radio frequencies which you currently listen to will be re allocated for other
uses such as emergency ser vices. This means that today you are one of the pioneers
using this technology, however in a shor t space of time everybody will benet from
clear digital radio.
Digital radio offers an abundance of new digital only stations and improved sound
quality. There are no frequencies to remember so the CDAB51R can be tuned by
searching through station names. The audio quality of DAB is near that of a CD with
virtually no interference and no retuning. DAB is also enhanced with DLS (Digital
Label Segment), this is data transmitted by the station which may include information
about the station, program or song (see page 9).
The BBC was the pioneer of digital radio, beginning transmissions in September
1995. Digital One, the national commercial radio multiplex operator, began
broadcasting in N ovember 1999. There has been a growth in the number of digital
radio stations throughout the UK and both the BBC and Digital One are committed
to extending their c overage. Digital One currently covers 80% of the UK population,
soon to inc rease to 85%, and the BBC covers 65% with the aim of increasing
coverage to 90%
Your CDAB51R will receive DAB programs broadcast on Band 3 digital radio (174240MHz). There are a total of 41 channels within this range numbered 5A to 13F, the
number of channels you can rec eive will be dependant on your location and signal
strength. The UK has been allocated seven multiplexes by the Radio Authority - in the
spectrum 217.5-230.0 MHz, which are numbered 11B to 12D.
A multiplex is a broadcaster such as BBC National DA B or Digital One who will
provide a host of dif ferent st ations within their multiplex. If we consider the BBC as an
example, the following diagram shows how the BBC multiplex may work.
Below the main multiplex provider (in this case ‘BBC National DAB’) will be a number
of primary stations. These are labelled with the station name (e.g Radio 2) rather than
the frequency. This allows you to tune the CDAB51R by station name, which is easier
than trying to recall frequencies.
Sometimes a secondary service station may be provided by the broadc aster, for
instanc e this is sometimes used when an alternative commentary is provided on a
sporting match or event. These secondary service stations are not permanent and
may not always be used for broadcast. When a secondary station is available below
the primary station, a ‘>’ symbol will be displayed after the primary station name. A
secondary station can be recognise by the ‘<’ symbol before the secondary station
name.
Check how many stations you can get
in your area by texting DAB and your
postcode to 88600#, or nd out which
stations are available on the website at:
