The Shortwave radio spectrum has been used for more than 30 years by the all the intelligence agencies around the world to transmit secret coded messages. They use Number Stations to transmit these messages to their agents wherever they are in the world.

These shortwave Numbers Stations are a perfect and an anonymous method for one way communication to their spies.  The spy can be located anywhere in the world and by using these Number Stations they can be contacted and communicated with using a standard and totally unmodified shortwave radio. The encryption method used by the Numbers Stations is known as a One Time Pad and is unbreakable.  It is almost impossible to track down where the message has been sent from and to whom the message recipient is.  This is why a Number Station is a powerful and effective system of communication.

Almost all of these Number Stations operated on rigid schedules, and they transmit in many different languages, employing both male and female voices which repeat strings of numbers or even phonetic letters 24 hours a day, 365 days a year.

The voices use varying pitches and intonation.  Some, like the spooky Swedish Rhapsody, thought to transmit from Germany, uses a child’s voice.

The Swedish Rhapsody

You might think that these espionage activities should have ended after the end of the cold war, but nothing could be further from the truth. The Number Stations seem to be as busy as ever, with new and bizarre  transmissions being heard every day.

So why, in over 30 years of transmissions have these Number Stations gone almost totally unreported? Who’s really behind the Numbers Stations, and why are the eastern European Numbers Stations still transmitting? Why is there a Numbers Station in the Czech republic transmitting 24 hours a day? How are these Numbers Stations allowed to interfere with air traffic control and ships without having to answer to anybody?  Why does the Swedish Rhapsody Numbers Station use a child’s voice?  These are just some of the questions that still remain unanswered.
