Burbling noises and breakup on DAB radio

Burbling noises and breakup can indicate a weak DAB signal. It could be due to either a transmitter fault, poor coverage or related to the weather.

Transmitter problems and coverage

Each DAB multiplex is broadcast using a specific frequency and the transmitters used by that specific DAB multiplex all use the same frequency.听This is known as a single frequency network (SFN).听If you can receive a service from more than one transmitter, then you get the benefit that your radio combines the signals from all the transmitters it can receive. If there is a problem with one of the transmitters you can receive, you may start to hear burbling noises or break up as there may now not be enough signals for good reception.

Use our听transmitter tool听to see the status of your local transmitters and also to see if you are in a good DAB reception area.听The transmitter tool can only show faults with 主播大秀 services.

Weather

Weather impacts are rare for DAB as but certain weather conditions allow the DAB signals to travel further than normal. This can have a negative impact on an SFN and result in burbling noises or break-up of the audio.听
