-Caveat Lector- >From TheIndependent (UK) > HOW BRITAIN EAVESDROPPED ON DUBLIN > > > THE MINISTRY of Defence "Electronic Test Facility", a rather > mysterious 150-ft high tower stands isolated in a British Nuclear > Fuels Limited site at Capenhurst, Cheshire. > > Locals knew that the tower housed a dark secret but did not know > what it was. That secret is now out. > > The tower was craftily erected between two BT microwave radio > towers carrying telephone traffic. The ETF was the ideal place to > discreetly intercept international telephone calls of the Irish > government, businessmen and those of suspected of involvement > with IRA terrorism. > > Channel 4 filmed extensive BT equipment inside the building, > including optical fibre cables linking the tower to the MoD's > communication system. > > The hi-tech white ETF tower included eight floors of advanced > electronic equipment and three floors of aerial galleries. > > These were used to extract and sort the thousands of > communications passing through every hour. Fax messages, e-mails, > telexes and data communications were automatically sorted by > computers scanning their contents for key words and subjects of > interest. Telephone calls could be targeted according to the > numbers dialled or by identifying the voice of the speaker. > > At the time the tower first came into operation the IRA campaigns > were raging. > > Relations between the British and Irish government's were not > always smooth, with the British suspecting their Irish > counterparts of being sympathetic to the IRA. > > Since the early 1990s, the British electronic spy agency GCHQ and > its American counterpart NSA have developed sophisticated > libraries of voice profiles to use in scanning international > telephone messages. > > The ETF tower was operated by personnel from an RAF unit based in > Malvern, Worcestershire. The "special signals" section of the RAF > "Radio Introduction Unit" install and run projects for GCHQ. > > According to local residents, the site was manned 24 hours a day > by a team of two to three people, until the start of 1998. > > Besides the Capenhurst tower, communications to and from the > Irish Republic were also intercepted at a similar but smaller > GCHQ station in County Armagh. This intercepts microwave radio > and other links between Dublin and Belfast. > > A third GCHQ station at Bude, Cornwall, intercepts western > satellite communications, including to and from Ireland. > > From 1990 until 1998 the Capenhurst ETF tower intercepted the > international communications of the Irish Republic crossing from > Dublin to Anglesey on a newly installed optical fibre submarine > cable, called UK-Ireland 1. > > From Anglesey, the signals were carried across Britain on British > Telecom's network of microwave radio relay towers, centred on the > BT Tower in London. > > The key link, from Holyhead in Anglesey to Manchester, passes > directly over the Wirral peninsula to the south of Birkenhead. > The ETF tower was built to pop up into this beam. > > When the new cable was planned in the mid 1980s, intelligence > specialists at the Defence Ministry and GCHQ Cheltenham, the > electronic spying headquarters, realised that the radio beams > passed directly over the nuclear processing plant at Capenhurst. > > During 1988, a temporary interception system was built on the > roof of the BNFL factory. When tests of the Irish interception > system proved successful, intelligence chiefs decided to go ahead > with a full-scale system. > > Within the Defence Ministry, the project was classified "Top > Secret Umbra". The codeword Umbra is used to designate sensitive > signals intelligence operations. > > Not even BNFL, on whose land the ETF tower was built, was let > into the secret. > > The Ministry of Defence held a meeting with residents early in > 1989 and urged them not to talk about the site. In return, they > were given free fencing and double glazing. > > The architects were told that the tower had to contain three > floors of aerial galleries, each with four special "dielectric" > windows. These are opaque to visible light, but allow radio beams > to enter. > > By building the tower in this way, no-one could see what aerials > were inside, or where they were pointing. > > But the architects' plans, lodged at the local authority offices, > revealed the true purpose of the tower. > > The plans revealed that the radio transparent windows had to be > aligned on an extremely precise compass bearing of 201.12 degrees > to magnetic north. > > Aerials pointing through these windows would point precisely at > the British Telecom towers at Gwaenysgor, Clwyd, and Pale > Heights, near Chester. These are the towers carrying the > Ireland's international communications links through Britain. > > During installation in 1989 and 1990, defence officials were > concerned to conceal what was going into the tower. To disguise > it, contractors vans were repainted in the livery of BT and other > public utilities. BT refused to say whether this had been done > with their knowledge and consent. > > Since the Irish telecommunication moved onto a different system > over a year the Capenhurst tower has been made redundant.
