FM radio

FM, which stands for frequency modulation, is also known as VHF (very high frequency). The FM broadcasting band extends from 87.5 MHz to 108 MHz. This includes Radio 1-4 but does not include Radio 6 Music, Radio 4extra, Asian Network, Radio 1Xtra and Radio 5 live Sports Extra which is only available on DAB.

Though FM has the potential to deliver excellent quality, most reception problems on FM radio are caused either by a weak signal or by some kind of interference.

 The reception you get can be influenced by a number of factors:

  • Reception can vary within a localised area, and some remote areas of the UK are without usable FM signals.
  • Under certain weather conditions, interference can occur between transmitters using the same frequencies. This is more likely in warmer weather, and is most prevalent along the coast.
  • Pirate radio interference can be a frequent nuisance, particularly in urban areas.
  • The precise position of your FM radio can affect reception significantly. It can even vary between stations.
  • Pull-out or ribbon aerials used inside the room are prone to picking up interference from household equipment of all kinds.
