WW2 “Y” Listening & DF Station

During World War II, a building on Ramore Head near the Coastguard Lookout was used as a top-secret ‘Y-station’ inside which the Women’s Royal Navy Service maintained a 24-hour Direction Finding (DF) and listening operation. The listening operation intercepted enemy transmissions from warships, submarines and Nazi occupied countries in Europe and sent the messages to the Top Secret British centre for code-breaking and de-coding at Bletchley Park.

The Direction Finding equipment in use allowed the operators to fix an accurate bearing to the source of the transmission. With a minimum of two such bearings from DF Stations far apart it was possible to accurately pinpoint the exact location of the source of the transmission. This information could then be used by the Military to take further action against these targets.
