To this day, no government agency in the world will admit to running a numbers station. Some people have taken to the road with direction finding equipment.Yet, in a 1998 article published in "The Daily Telegraph", an official spokesperson for the U.K. agency that regulated radio regulations at the time was allegedly quoted as admitting that numbers stations are indeed what the public thinks they are that that no one should be mystified by it because the information is not for public consumption.
Numbers stations have come to be known as OWVL (One Way Voice Links) that could be used to communicate with the desired party so long as the party could justify possession of the shortwave receiver, was not under technical surveillance, and was well trained in the tradecraft.

Understanding numbers stations classifications
You'll notice each numbers station has an alpha-numerical identifier assigned to it. Here's what they mean:
E = English speaking station
G=German speaking station
S=Slavic speaking station
T=Station in unknown language
M=Morse Code station (CW in today's popular terms although it is technically incorrect)
V=any language not noted in this list elsewhere
X=all other transmissions including digital modes, polytones, etc

Two true stories from Shortwave America:
While listening some long time ago, this author witnessed V2 (Cuban Numbers Lady) use the same pad a second time! Around September 12th, 2010, Shortwave America posted a signal report on V2 as heard on 5885Khz, and within SECONDS after the post was published at HFUnderground, V2's signal was full strength commercial quality! Be careful posting what you hear, they just might be watching the message boards ladies & gents!
In the modern day, encrypted communications are said to be absolutely impossible to crack although the reality is that every type of communications including encryption has it's shortcomings. These numbers stations are not using encryption however, because we can hear their voices and encryption means the listener hears a signal but with the difference that there exists "digital hash" on top of the voice, thus making the voice or data transmission unintelligible. This type of encryption is mostly encountered with Motorola(tm) systems that use 128 bit type encryption or better. Although this encryption can be used on the HF bands, it isn't used because it's more of a pain than anything else and it costs major amounts of cash to obtain and maintain. With these systems, there is always the threat of the loss of the digital encryption key under certain circumstances.
Even the U.S. Military uses a system of ciphering that allows them to send EAM's in the clear because no one will ever figure out what the message is about...they use a one time pad, one time key, etc.
Common knowledge is that a member of the Enigma2000 group broke a numbers station pad!
What you now know is that these numbers stations are not a novelty, not a distraction, not some pirate playing games, but real communications directing intelligence agents of the world to carry out their orders. The conspiracy theories end here, and real learning has begun. Enjoy this article, refer to it as often as you need, pass it along to other people, it was a pleasure to put this piece together for all of the readers and participants of the radio world!
