Over a million radio listeners in Eastern England are without an FM service after a transmitter mast at Peterborough in Cambridgeshire collapsed onto the transmitter building and neighbouring fields after catching fire on Saturday evening. The station covers much of Cambridgeshire, and parts of Lincolnshire, Northamptonshire, Leicestershire, Bedfordshire, Buckinghamshire and West Norfolk. Services broadcast from the site include BBC Radios 1,2, 3 and 4, BBC Radio Cambridgeshire, BBC digital radio and Classic FM. Mobile telephone reception has also been affected. Scenes of crime experts and forensic teams are at the transmitter site, which is owned by Crown Castle International.
