Troubleshooting DAB reception

DAB reception problems can be caused by many things. It is often a process of elimination to find the cause.Ìę

If the sound begins to burble or cut out altogether or you have lost a radio station it is probably due to one of the following: Ìęthe signal has weakened due to a network fault or there’s a problem with your equipment or installation. Ìę

Transmitter faults

By using our Transmitter Checker, you can check whichÌęDAB radio services are available at your location. It will also show you any transmitter faults.ÌęCurrently it reports on network DAB stations only; Local and NationsÌęradio faults are not included.

Works and Warnings

Check whether there are any known works or warnings that might be causing the problem.

TuningÌę

DAB uses multiplexes to group services together.ÌęThe ±«Óătv network stations, e.g. ±«Óătv Radio 1, ±«Óătv Radio 4Ìęare grouped together in a single multiplex. Nations and Local radio services are carried on a mix of commercial multiplexes.

Try switching your radio on and off.ÌęIf you still have a problem use the ‘autotune' function to re-tune. If this does not work, a full re-scan might be needed.ÌęCheckÌęyour radio manual for specific instructions on doing a full re-scan. Further information on tuning your DAB radio can be found by visiting the Ìęsite or see ourÌęDAB tuning guide.

Portable Radios

Ensure the telescopic/integrated aerial is fully extended. Try moving the radio around to see if you can find a better position where you get good reception of all the stations you want to listen to.

In most circumstances the supplied telescopic aerial should be perfectly adequate, and as a rule of thumb DAB aerials tend to work best when vertical and extended at least 35 cm. If your radio reception is poorÌęthen you could considerÌęan external aerial for best reception quality. Even in good areas an external aerial will guarantee optimum performanceÌęand will also ensure consistent listening quality.

Many Digital radios have a signal strength display which enables you to position the Radio for the best reception (usually a number of blocks) as a guide of reception quality. Unfortunately, some radios are less sensitive than others and need careful positioning to work reliably. If your radio displays signal strength, use this as a guide to ensure the best position.

Our DAB installation guide provides further information.

External aerials

It is important to check the cables and the aerial for damageÌęand that they are operating correctly.ÌęMake sure any cables between your radio equipment and aerial are connected securely. For further information see our DAB installation guide.

Damaged Cables

Water can get into external cables and can cause reception problems. To rule this out see our guide on water damage to cables.

Car Radios

Radio reception can drop out when on the moveÌędue to changes in topography. See ourÌęcar radio guideÌęfor more information.

Weather

Radio signals can be affected by fine weather including high pressure. The only solution is to wait for the weather to change, you should not re-tune during this time. Our information on how clear skies and fine weather can affect your radio receptionÌęmay be useful, please see our weather guide.

Lost reception of one or more station within a multiplex

If all other stations are working ok and you have just lost one station. The problem could be due to a number of reasons, the station may have stopped broadcasting or have moved multiplexes rather than a radio fault. AllÌęof the stations in one multiplex should be behaving the same way.Ìę

Interference

If you are still having problems, it is possible an unwanted signal is the cause. For information on the .
