Ghost Voice Created Nazi Chaos
The B.B.C., the General Post Office, and Cable and Wireless, joined in the “Corona” system which was to be used as a means of confusing, distracting and annoying the enemy, even to the extent of giving the German fighters instructions contrary to those which they received from their own ground controllers. Instead of transmitting “noise”, as was the case with the ordinary “jamming” tactics, it was decided to use a “ghost voice” – a fluent German speaker. This was heard by the enemy for the first time on the night of October 22-23, 1943.

The target on this occasion was Kassel, and before the end of the raid there was chaos in the enemy night defence organization. A furious German ground controller was warning his aircraft to “beware of another voice” and “not to be led astray by the enemy”. The “voice” not only spoke idiomatic German but could also mimic perfectly the voices of his opposite numbers. After a particularly violent outburst by the German controller, the “voice” said: “The Englishman is now swearing.” The German's reply was “It is not the Englishman who is swearing by me!”

Addendum. Lifted from rafcommands forum. Book on No. 100 Group RAF, Confound & Destroy by Martin Streetly gives Y-station at West Kingsdown (near Sevenoaks) as 'chief' of the monitoring station which listened in on German GCI transmissions .

Transmitters were at Rugby (3x) and Leafield (1). These were GPO's VHF transmitters.

Women operators first used by British on 25/26 November 1943.

As well as counter-instructions, pre-recorded mix of German voices or music was broadcast over the frequency.
