Hissing and Fading on your FM radio

FM reception is quite generallyreliable but can be disrupted by a weak signal.


This can be due to:

Reduced transmitter power

Use our Transmitter Tool to see whetheryour local transmitter is currently affected by maintenance work.

Stereo Signal

Try moving the radio to another position, such as near a window, higher up, or another room. If you get hiss when listening to a stereo signal try switching to mono. Stereo reception needs a stronger signal than mono.

Aerial

If you have a portable radio you will be able to pick up more of the receivable signal if your telescopic aerial is fully extended.For hi-fisystems check your aerial isn’t broken or become loose. If you have an external or loft aerial check they are functioning correctly.

Tuning to the wrong transmitter

Use our Transmitter Toolto check you are tuned to the best frequency for your area, as you can often pick up more than one signal.

Weather

Very occasionally, the weather, usually highpressure, can result in a weakened signal. There is nothing anyone can do about this and the only answer is to wait for the weather to change. For more information see our guide onhow weather can affect radio reception.
