Inside a 'Y'
Station
Messages transmitted
to and from U-boats were intercepted in Britain by Royal Air Force
'listening' stations, known as 'Y' Stations.
The 'Y' Stations
also intercepted thousands of other enemy messages each day.
Outside a 'Y'
Station a forest of tall aerials picked up radio signals from
as far away as the Soviet Union and Japan.
Inside, a team
of Morse code operators worked 24 hours a day, listening in to
coded messages and writing them down.
Your job would
be to translate the Morse signals into letters and write them
down as fast as you could - at least 90 letters a minute.
If you made just ONE mistake it would be impossible for
the code-breakers to break the code.
Listen to the sounds you would have
heard if you were one of the many servicewomen or civilians who
worked at a secret 'Y' Station.
