Number Stations

What are number stations? A "number station" is a type of broadcast sent over shortwave radio. Many people believe (and there is evidence) that these are run by foreign intelligence agencies, for the purpose of sending coded information to agents out in the field. That is the simplest definition for a rather complex topic.

What do they sound like? If you hear a numbers station, none of it will make sense. Only the intended recipient of the broadcast can decode or decrypt it, to reveal a message. That is often accomplished using a "One-Time Pad." (Click HERE or HERE to learn more.) 

Numbers stations have been around since World War I, but their usage peaked during the Cold War era (1960s-1990s.) Originally, a live person would read the numbers over the radio. Today, numbers stations vary. Most are recordings of computer-synthesized voices, but there's also morse code, tones, data bursts, and more. 

Many years ago, enthusiasts created a system called "ENIGMA" to organize and name the numbers stations. Basically, they're classified by language or signal: English, German, Slavic, Morse Digital, and Other. Click HERE to view a summary.

Why do they exist when we have cellular networks and the internet? The website Priyom.org states it well: "Numbers stations offer a powerful advantage in our modern world: practically complete anonymity. The recipient of the message can be almost anywhere in the world, and receive instructions without fear of being traced through a phone call or internet connection. All the recipient needs is a shortwave radio and to be in the right place at the right time." 

Radio waves exist naturally, constantly bouncing off Earth's atmosphere. Shortwave, especially, can be heard over very long distances. It is simple and inexpensive to use, unlike modern communication systems which rely on networks, cables, hardware, software, and so on. A numbers station can be broadcast over shortwave and heard on a simple handheld radio hundreds of miles away, which is advantageous in situations where cellular service is bad, the internet is down, or power is out. Hence, shortwave radio (and numbers stations) continue to be used as a line of communication by even the most technologically advanced nations. To learn more about numbers stations, here's where to get started:
