'Pirate radio puts aircraft in danger' http://www.thisislondon.co.uk/ by Anthony France Hundreds of plane passengers' lives were put at risk by a pirate radio station broadcasting on the same frequency as air traffic control operators, it has emerged. The pilot of a jet which was coming in to land at Heathrow last week warned that his instructions from ground control were being drowned out by dance and garage music from a transmitter in south London. He was forced to switch to a back-up frequency in order to continue talking to air traffic control, and managed to land the plane safely. Yesterday, Telecoms Minister Stephen Timms backed the battle against radio piracy by joining enforcers in a raid on a south London tower block. Mr Timms said: "Pirate radio stations are threatening public safety every day. Their illegal broadcasts run the risk of disrupting essential radio services like air traffic control and emergency service communications. People's lives may be put at risk. "Most of the radio stations' transmitters are very crude and even when they are supposed to be broadcasting on one frequency they often are not." During the incident on 25 August, which the minister revealed yesterday, the pilot complained of interference coming from the Battersea area as he made his final descent towards Heathrow. Pilots coming in to City Airport in east London have also complained of music in their headphones. Accompanied by Mr Timms, journalists and photographers, the Radiocommunications Agency carried out a raid on the boiler room on the 16th floor of Bannerman House in Lawn Lane, Vauxhall. Two pirate radio stations broadcasting under the names Vibes 93.8FM and OlSkool 103.4FM have been known to operate from the block of council flats. Barry Maxwell, director of the Radioc o m m u n i c at i o n s Agency, said: "You can imagine how difficult it was for the pilot as he was about to land to have music blasting over his instructions. Actions like this mean that they cannot get vital messages at a time when they need them. "It is very dangerous and we need to clear these radio stations from the frequency. Many of the transmitters used cost about £300 and are very unstable, which means that the frequency drifts from one place to another. "We are fighting a constant battle against the pirates. Our team of radio engineers undertake difficult and dangerous work in making the airwaves safe but it's not only about raids and seizing equipment. We have people who also pursue not just the pirates but their suppliers and those who work behind the scenes." Mr Maxwell added that " interference with aircraft is very rare and we take the matter seriously when we receive complaints". The agency estimates there are up to 80 pirate radio stations operating in London, but finding those responsible is difficult. Most radio studios are miles from their transmitters, to which they are connected via a microwave link. Nearly 1,500 raids are carried out on pirate broadcasters each year of which around 90 per cent are in the Greater London area. The maximum penalty for running a pirate radio station is an unlimited fine and up to two years in prison. During the raid on the flats in Vauxhall, enforcement officers from the Radiocommunications Agency used steel cutters to remove metal transmitter boxes from their mounts in the boiler room. Most transmitters have an output of 100 watts which enables pirate stations to broadcast across an area stretching between 10 and 12 miles.
