You can purchase this album on iTunes and listen to these spy broadcasts.

Shortwave works by broadcasting carrier waves that bounce between the ionosphere and the earth’s surface. The signals travel over curved surfaces and bounce from continent to continent.

An atavism to Cold War technology and subterfuge, number stations still operate in utter secrecy, except that with a strong enough tuner, you can still pick up their content. Number stations are broadcasting shortwave signals that appear to be encrypted data hidden inside odd musical notes, bars, measures, and anonymous voices reading lists of numbers of letters or words. Stochastic broadcasts containing random and repeating data, or longer pieces of music as well.

The Conet Project is a 5 CD collection of the various add broadcasts from numbers stations around the world. It costs anywhere from hundreds of dollars to sixty dollars.

You can purchase the broadcasts on iTunes. They are fascinating to say the least.

What fascinates is not just the creepy arcane atmosphere around it. What I keep thinking about is that fact that the communications are no doubt someone enacting a violent policy on someone else, or passing secrets that could hurt someone for political reasons alone.
