By the Numbers

Today on Hummadruz we’re going to look at the mysterious phenomenon known as Numbers Stations: radio beacons that broadcast strange shortwave radio transmissions that consist of strings of numbers read in sequence and usually identified at the start with some kind of audio ‘logo’ such as a sound or a piece of music. No-one really knows the purpose of Numbers Stations (well, I say ‘no-one’ – obviously someone does), but it is likely that they are used to send coded messages from government security agencies to their undercover operatives out in the field. In other words, this is spy stuff. It is thought that the first Numbers Stations started up shortly after World War 1, and it is certain that there were many operating after World War 2 and throughout the Cold War.

The most well-known of the Numbers Stations is probably The Lincolnshire Poacher, so called because of its use of the folk song of that name as its identifier.

The Lincolnshire Poacher was a very powerful shortwave broadcaster, purportedly operated by Britain’s MI6 out of Cyprus. It had a similarly powerful sister station called Cherry Ripe which was believed to be in Australia.

Both these stations ceased broadcast around 2008/2009, but there are still dozens of Numbers Stations in operation, especially in Eastern Europe and South America. The mysterious repeated sets of numbers are almost certainly a type of code, most likely a system called a ‘one-time pad‘. A one-time pad code is completely uncrackable if the people employing it stick to the strict protocol. Short wave radio is an ideal method for transmitting the information, due to its long reach, and the relatively low tech and easy availability of portable shortwave receivers.

Some Numbers Stations use a type of phonetic alphabet system that can result in a very surreal effect. Here’s a station called Nancy Adam Susan:

The robotic hypnotic quality of the echoic female voice reciting names over and over seems to me much more disconcerting than the EVP phenomenon that we talked about recently on Hummadruz. Here’s perhaps the creepiest of all the currently broadcasting Numbers Stations, dubbed Swedish Rhapsody (the name of the melody):

The tinkly music box tune and the sampled voice of a young girl are surely the stuff of radio nightmares. One of the most fascinating things about these Numbers Stations is that on a purely aural level they are evocative and intriguing, and speak of a Cold War era that is surely fading as we move into the world of high speed internet and digital encryption. If you’d like to hear some more of these strange radio relics, there’s a substantial collection of recordings here on archive.org – these are part of The Conet Project which is available through Irdial Discs. Irdial also makes the entire collection available for free as mp3s.

  1. I worked on a film recently called The Numbers Station, with John Cusack, and while I haven’t seen it in its entirety to offer a valid critique of it, I can confidently say I was asked to put in many more muzzle-flashes and explosions than a radio station broadcasting lists of words and numbers would seem to imply.

    • Coincidentally, last night we watched The Raven, a film with John Cusack playing Edgar Allan Poe and it seemed to have many more muzzle flashes and horse chases than I remembered from the stories. John Cusack has a lot to answer for.
