Shortwave Radio: One of 5 popular espionage techniques from former USSR

(Source: Top Secret Writers)

Shortwave radios have been a tool of the espionage trade for many years. Radios can transmit information encoded to be picked up by the receiver and then decoded.

This technique was used throughout World War I, World War II, and the Cold War. Like Steganography, radiograms are still being used today.

[…]The techniques were used by the Soviets during the Cold War many years ago, but it seems that they have remained long-lasting fixtures in Russian Espionage.

We actually reported on this back when news broke about the russian agents who used numbers stations for espionage purposes. Yep, shortwave radio is your friend if you don’t want people tracing where you are and what you’re listening to.

Mind you, when you live in a country that suppresses free speach, you also reach for a shortwave radio.

Russian Agents Used Shortwave Radio to Receive Coded Messages

Many of you may have noticed in the news yesterday that shortwave radio was used by the 11 Russian agents who were carrying out espionage within the United States. An article in the New York Times noted that one of the methods they used to communicate with the S.V.R. headquarters in Russia was via shortwave radio. The article mentioned that the agents would send “coded bursts of data” via shortwave transmitter.

The NY Times article failed to mention that the agents no doubt received messages from Russia via shortwave numbers stations.

So why is shortwave radio–a rather “low-tech” communications medium–used in modern espionage? The primary reason is it’s almost impossible to trace, thus messages leave little to no breadcrumbs for one to follow back to the source.

For decades, radio listeners have been trying to figure out from where numbers station broadcasts originate. They’ve had very little success. Indeed, the only breaks we’ve had have been when the broadcasting station makes a mistake. This has happened once with a numbers station message originating from Radio Havana Cuba. Listeners heard the faint sound of an RHC broadcast in the background–they were obviously hearing noise from across the studio hall.

Of course, another reason shortwave radio is used to relay secret messages is because it’s almost impossible to block. I wrote an article called “When shortwave radio is better than the Internet” that describes why this characteristic alone is an important reason to keep shortwave stations on the air around the world. No government or local authority can prevent you from listening to shortwave broadcasts–whether you’re a spy (like this lot) or simply living in a country where the folks in charge like to  control your access to the news and information.

One small shortwave  radio can break through all of that red tape.

UPDATE: For more information on how radio was used by these agents, check out the US Department of Justice’s website. In particular, check out pages 11-12 in this document. (Thanks to David Goren for this tip.)
