Geocache Description:

You will find nothing at the posted coordinates..

Telephone, Internet and even satellite transmissions can be monitored. E-mails can be intercepted and read. Some government agencies have the money and resources to monitor communications and trace both sender and receiver. An example is the huge ECHELON project which globally intercepts and identifies all kinds of communications. In times of conflict, countries can simply block the Internet or other communications, or even simply switch off satellites. There have been successful tests to destroy satellites with missiles, making satellite communications unreliable during a serious conflict. Or did you really believe to continue using telephone or Internet between, let's say, Russia and the United States, if they where at war with each other?

Imagine a war broke out and intelligence personnel are operating behind enemy lines. The only secure and reliable way to communicate with them would be the good old-fashion long distance shortwave radio. But even in times of peace, some covert operations are so sensitive that discovering them would bring governments big problems or embarrassment. It is believed that some numbers stations continuously send fake messages, just to keep the lines open, ready for use. Those who monitor these stations are unable to notice when a station suddenly changes from sending random numbers to operational encrypted traffic. A good example is the Lincolnshire Poacher, sending messages of 200 groups each, every day, for almost 40 years. Reasons enough why numbers stations are still active and useful. With their long and outstanding career of more than 70 years, the numbers stations have become an icon of espionage.

And still, every single day, numbers messages are transmitted all over the world, spoken in English, Russian, Spanish, Chinese and many other languages. Who's broadcasting them and, even more intriguing, who's listening to them...?
Can you figure this one out??
