Y service
The "Y" service was a network of British
Foreign Office (MI6 and MI5). The General Post Office and the Marconi Company provided some receiving stations, ashore and afloat. There were more than 600 receiving sets in use at Y-stations during the Second World War.[2]
Role
The "Y" name derived from Wireless Interception (WI).Government Code and Cypher School at Bletchley Park in Buckinghamshire.[4]
In the Second World War a large house called "Arkley View" on the outskirts of Barnet (now part of the London Borough of Barnet) acted as a data collection centre, where traffic was collated and passed to Bletchley Park; it also housed a Y station.[5] Much of the traffic intercepted by the Y stations was recorded by hand and sent to Bletchley by motorcycle couriers, and later by teleprinter over Post Office landlines.[6] Many amateur radio operators supported the work of the Y stations, being enrolled as "Voluntary Interceptors".[7]
The term was also used for similar stations attached to the India outpost of the Intelligence Corps, the Wireless Experimental Centre (WEC) outside Delhi.[8]
Direction-finding Y stations
Specially constructed Y stations undertook
Admiral Dönitz told his commanders that they could not be located if they limited their wireless transmissions to under 30 seconds, but skilled D/F operators were able to locate the origin of their signals in as few as six seconds.[9]
The design of land-based D/F stations preferred by the
Allies during the Second World War was the U-Adcock system, where a small operators' hut was surrounded by four 10 ft-high (3.0 m) vertical aerial poles, usually placed at the points of the compass. Aerial feeders ran underground, surfaced in the centre of the hut and were connected to a direction finding goniometer and a wireless receiver, that allowed the bearing of the signal source to be measured. In the UK some operators were located in an underground metal tank. These stations were usually in remote places, often in the middle of farmers' fields. Traces of Second World War D/F stations can be seen as circles in the fields surrounding the village of Goonhavern in Cornwall.[10]
