Editing Lorenz cipher (section)

===Interception===
Tunny traffic was known by [[Y Service|Y Station]] operators used to listening to [[Morse code]] transmission as "new music". Its interception was originally concentrated at the Foreign Office Y Station operated by the [[Metropolitan Police]] at [[Denmark Hill]] in [[Camberwell]], London. But due to lack of resources at this time (around 1941), it was given a low priority. A new Y Station, [[Knockholt]] in [[Kent]], was later constructed specifically to intercept Tunny traffic so that the messages could be efficiently recorded and sent to Bletchley Park.<ref>{{Harvnb|Good|Michie|Timms|1945|p=281}} in ''Knockholt''</ref> The head of Y station, [[Harold Kenworthy]], moved to head up Knockholt. He was later promoted to head the Foreign Office Research and Development Establishment (F.O.R.D.E).
