The Spies Are Still Out There

I can't believe it - after listening to my short wave radio (well, ok.. to be more specific, a lot of static, China, Vietnam, Cuban, Russian radio) for the last few days I found my first "numbers station!" I was scanning different bands while waiting for my supplier to arrive when I tuned into 17,450 kHz and found 5-string numbers being repeated in Spanish. After doing some research this is more than likely the station commonly referred to as "Atencion" - Cuban based. It is true, however, that different clandestine agencies around the world broadcast in many languages and don't necessarily rely only on numbers. They use phonetic alphabets, strings of sounds, morse code, data burst transmissions as well as cartoon sounds. Its weird to know that somebody out there doing some highly dangerous and risky stuff on behalf of their government might be listening to this.
