FM reception is quite generally reliable but can be disrupted by a weak signal.
This can be due to:
Reduced transmitter power
Use our transmitter tool to see whether your local transmitter is currently affected by maintenance work.
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.
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-fi systems 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 tool to check you are tuned to the best frequency for your area, as you can often pick up more than one signal.
Very occasionally, the weather, usually high pressure, 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 on how weather can affect radio reception.
