Y stations

The 'Y' stations, were listening stations set up in various regions during World War 2, and consisted of several short wave communications receivers tuned into various frequencies. The 'Y' station operators had to have excellent Morse code skills, and would spend their time listening for unusual Morse code signals, usually sent in code by enemy radio operators. The operators would then write down the coded message as it was sent, the message would then find its way to a code breaking station such as Bletchley Park, where the code breaking teams would go to work on it attempting to break the enemy code.
