What is causing my DAB radio to sound like a kettle boiling?

There are a number of reasons why this effect can be heard and usually not linked to interference. The main cause is normally a weak signal. It is important that you check you are in a good coverage are for DAB and that your radio is well positioned and the aerial is fully extended if using a telescopic aerial.
