Shortwave Radio Recording: “The Buzzer” on 6,998 kHz

UVB-76-Buzzer

Screen capture of the Web SDR waterfall tuned to 6,998 kHz.

On Friday, Andrea Borgnino, tweeted that he could once again hear “The Buzzer” on 6,998 kHz. Of course, during the day, I couldn’t hear  the signal from my home in North America.

I could, however, easily hear the signal via the University Twente Web SDR in the Netherlands.

Here’s my recording:

As I’ve mentioned before, I’m pretty sure this is simply a pirate having a little fun relaying UVB-76 audio on 6,998 kHz.

My buddy, Andrea Borgnino, recently heard UVB-76 (The Buzzer) on 6,998 kHz with his Elecraft K3 in Italy. Check out this short video:

While the audio sounds identical to that of UVB-76’s on 4,625 kHz. I strongly suspect this is simply a pirate radio station relay–especially since it’s broadcasting just below the 40 meter ham radio band. Either way, it’s a great catch! Thanks for sharing, Andrea!

Hackaday: “Secret Radio Stations by the Numbers”

One thing has stayed with the James Bond movie franchise through the decades: Mr. Bond always has the most wonderful of gadgets. Be it handheld, car-based, or otherwise, there’s always something to thrill that is mostly believable.

The biggest problem with all of those gadgets is that they mark Commander Bond as an obvious spy. “So Mr. Bond, I see you have a book with many random five character groups. Nothing suspicious about that at all!” And we all know that import/export specialists often carry exploding cufflinks or briefcases full of unknown electronics in hidden compartments.

Just as steganography hides data in plain sight, the best spy gadgets are the ones that don’t seem to be a spy gadget. It is no wonder some old weapons are little more than sticks or farm implements. You can tell a peasant he can’t have a sword, but it is hard to ban sticks.

Imagine you were a cold war era spy living in a hostile country with a cover job with Universal Exports. Would you rather get caught with a sophisticated encryption machine or an ordinary consumer radio? I’m guessing you went with the radio. You aren’t the only one. That was one of the presumed purposes to the mysterious shortwave broadcasts known as number stations. These were very common during the cold war, but there are still a few of them operating.

Jack Barsky: KGB spy who relied on numbers stations

JckBarsky

Many thanks to SWLing Post reader, Anthony, for forwarding this CBS/60 Minutes video: an interview with former KGB spy, Jack Barsky. During the interview, Barsky mentions that he received encrypted KGB “radiograms” via a numbers station he believed to be in Cuba. He admitted that the messages could take an hour to copy, then an additional three hours to decode. This is a fascinating story–well worth watching.

Here is the intro via 60 Minutes:

“Tonight, we’re going to tell you a story you’ve probably never heard before because only a few people outside the FBI know anything about it. It’s a spy story unlike any other and if you think your life is complicated, wait till you hear about Jack Barsky’s, who led three of them simultaneously. One as a husband and father, two as a computer programmer and administrator at some top American corporations and three as a KGB agent spying on America during the last decade of the Cold War.

The FBI did finally apprehend him in Pennsylvania but it was long after the Soviet Union had crumbled. What makes Jack Barsky’s story even more remarkable is he’s never spent a night in jail, the Russians declared him dead a long time ago, he’s living a quiet life in upstate New York and has worked in important and sensitive jobs. He’s now free to tell his story…as honestly as a former spy ever can.”

Numbers stations featured in Highbrow Magazine

towersMany thanks to SWLing Post reader, Richard Cuff, who shares this link to a numbers station piece in Highbrow Magazine; one of the more comprehensive numbers station articles I’ve read in a while.

Here’s an excerpt:

“Many nights, Spooks turn on their shortwave radios and drift through the frequencies. On any given night, one can hear amateur radio stations broadcasting church sermons, utility traffic for aircrafts – with the right equipment, you can hear/contact the International Space Station. Yet one of the most eerie, mysterious uses of shortwave is that of the numbers stations: stations that feature ominous – sometimes robotic – voices saying seemingly random number patterns.

Shortwave radio boomed in the 1920s: For decades, it was the only way to receive transmissions from far way. Numbers stations, as they are called now, have been around since World War I, though many of the most famous transmissions took place during the Cold War. These mysterious stations are all, to date, unlicensed. Some feature automated voices, others have what sound like children’s voices, another with a sultry woman announcing numbers. One station – a Moscow-based broadcast during a Communist party coup – featured only the number five repeated for hours.

Numbers stations and use of shortwave have declined after the Cold War, but there are still transmissions heard every day – the shortwave decline has not been as pronounced as one would expect. Part of the reason for this is that it is a secure means of one-way communication. Since the airwaves are being released out into the ether – the intended recipient is completely untrackable. Presumably, spies would carry a one-time pad, which would have the encryption code to be used (ideally) for just one broadcast (hence one-time). This makes decryption from pedestrians and enemies nearly impossible unless that one-time pad is misused or corrupted.

Almost all of the information we have on these numbers stations is due to hobbyists listening, sourcing, and sometimes attempting to decode the stations with their own radios. The communities of hobbyists are vast – and their logging can be prolific. There is the Spooks Spy Numbers Station Mailing List, the Conet Project (which compiles recordings of shortwave), the Spy Numbers Station Database, and many others. They keep track of the frequency, the time, the numbers, and sometimes record audio each time spooks hear a Numbers broadcast. These shortwave enthusiasts sometimes spend hours trying to locate the source of these broadcasts – sometimes, to no avail.”

Cold War Echo: RT investigates UVB-76

UVB-76-via-RT(Source: Russia Today via YouTube)

“From a lonely rusted tower in a forest north of Moscow, a mysterious shortwave radio station transmitted day and night. For at least the decade leading up to 1992, it broadcast almost nothing but beeps; after that, it switched to buzzes, generally between 21 and 34 per minute, each lasting roughly a second—a nasally foghorn blaring through a crackly ether.

The signal was said to emanate from the grounds of a voyenni gorodok (mini military city) near the village of Povarovo, and very rarely, perhaps once every few weeks, the monotony was broken by a male voice reciting brief sequences of numbers and words, often strings of Russian names: “Anna, Nikolai, Ivan, Tatyana, Roman.” But the balance of the airtime was filled by a steady, almost maddening, series of inexplicable tones.”

If you can’t hear UVB-76 from where you live via shortwave radio (4,625 kHz), you can always listen to this live stream.

Numbers station presentation by Peter Staal

Many thanks to Jonathan Marks who discovered the following video–a lecture by Peter Staal at TU Delft–on the topic of numbers stations:

Note that they attempt to sort out a technical problem in the first three minutes of the lecture.

Check out Jonathan’s post on Critical Distance for his comments and videos of Speech Morse Generators: the machines behind the numbers.
