Nations and Local radio services are carried on a mix of commercial multiplexes. Check whether there are any known works or warnings that might be causing the problem. If you still have a problem use the ‘autotune' function to re-tune. If this does not work, a full re-scan might be needed. Check your radio manual for specific instructions on doing a full re-scan.
Further information and guidance can be found by visiting the Get Digital site. 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. 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. 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 poor then you should consider the fitting of an external aerial for best reception quality. Even in good areas an external aerial will guarantee optimum performance and will also ensure consistent listening quality.
Our DAB installation guide provides further information. It is important to check the cables and the aerial for damage and that they are operating correctly. Make sure any cables between your radio equipment and aerial are connected securely. For further information see our DAB installation guide . Water can get into external cables and can cause reception problems. To rule this out see our guide on water damage to cables . Radio reception can drop out when on the move due to changes in topography. 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 h ow clear skies and fine weather can affect your radio reception may 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. All of the stations in one multiplex should be behaving the same way. If this does not help use the 'autotune' function to reinstall the stations into the memory or talk to your dealer or manufacturer. If you are still having problems, it is possible an unwanted signal is the cause. For information on the symptoms of interference see our sister website RTIS . The CAI ( Confederation of Aerial Industries ) is a recognised trade body which will be able to put you in touch with one of their members in your area. To enjoy the benefit of listening to DAB in your car you will need to ensure your aerial is able to receive a DAB signal. You may need to contact your car manufacturer to check. However, helically wound FM aerials are able to receive DAB. The best place to put a DAB aerial is on the roof of the car and as far from the engine as possible, to avoid any interference.
If your car radio is showing no signal or no service for a station you usually receive, this could be down to one of three things: DAB Transmitter Fault. If you know your location, you can use our transmitter checker to see whether there is a problem.
If not, then check the radio and the aerial to confirm they are working correctly. Poor DAB reception can also be caused by equipment used in the vehicle. For example, phone chargers or dash cams sometimes cause interference and affect your radio signal.
