What causes radio reception and interference problems?

Radio speakerBoth analogue radios (i.e. those that pick up broadcasts on the FM, MW, LW or SW frequency bands) and digital radio sets (e.g. DAB) need a good aerial to guarantee the best sound quality.

If you’re quite far from the nearest transmitter it can be difficult for radio signals to go through thick brick or concrete walls, so you might find that putting the radio on a window sill with the aerial near the window glass can help.

If the radio is close to an electrical device with a large motor (for example, a washing machine or fridge-freezer) this can also cause interference.

Try moving the radio from room to room to see if the reception problems improve or worsen.

If you’re using the radio’s built-in aerial, see if your radio allows you to plug in an external aerial. Most high street electrical shops will sell a desktop FM aerial which may allow for better reception.

If you have a rooftop TV aerial you may also be able to connect this to your radio. A qualified aerial installer can help with advice. The Confederation of Aerial Industries CAI) keeps a list of accredited installers.
