Somewhere in Russia a signal of mysterious beeps and buzzes has broadcast
since the high-water days of the Cold War. But why?

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.
The
amplitude and pitch of the buzzing sometimes shifted, and the intervals between
tones would fluctuate. Every hour, on the hour, the station would buzz twice,
quickly. None of the upheavals that had enveloped Russia in the last decade of
the cold war and the first two decades of the post-cold-war era—Mikhail
Gorbachev, perestroika, the end of the Afghan war, the Soviet implosion,
the end of price controls, Boris Yeltsin, the bombing of parliament, the first
Chechen war, the oligarchs, the financial crisis, the second Chechen war, the
rise of Putinism—had ever kept UVB-76, as the
station’s call sign ran, from its inscrutable purpose. During that time, its
broadcast came to transfix a small cadre of shortwave
radio enthusiasts, who tuned in and documented nearly every signal it
transmitted. Although the Buzzer (as they nicknamed it) had always been an
unknown quantity, it was also a reassuring constant, droning on with a dark,
metronome-like regularity.
They don’t know just what they’re listening to. But they’re fascinated by
the unending strangeness of the mindless, evil beeping.
But on June
5, 2010, the buzzing ceased. No announcements, no explanations. Only silence.
The
following day, the broadcast resumed as if nothing had happened. For the rest
of June and July, UVB-76 behaved more or less as it always had. There were some
short-lived perturbations—including bits of what sounded like Morse code—but
nothing dramatic. In mid-August, the buzzing stopped again. It resumed, stopped
again, started again.
Then on
August 25, at 10:13 am, UVB-76 went entirely haywire. First there was silence,
then a series of knocks and shuffles that made it sound like someone was in the
room. Before this day, all the beeping, buzzing, codes, and numbers had hinted
at an evil force hovering on the airwaves. Now it seemed as though the wizard
were suddenly about to reveal himself. For the first week of September,
transmission was interrupted frequently, usually with what sounded like
recorded snippets of “Dance of the Little Swans” from Tchaikovsky’s Swan
Lake.
On the
evening of September 7, something more dramatic—one listener even called it
“existential”—transpired. At 8:48 pm Moscow time, a male voice issued a new
call sign, “Mikhail Dmitri Zhenya Boris,” indicating
that the station was now to be called MDZhB. This was
followed by one of UVB-76′s (or MDZhB’s)
typically nebulous messages: “04 979 D-R-E-N-D-O-U-T” followed by a longer
series of numbers, then “T-R-E-N-E-R-S-K-I-Y” and yet more numbers.
Just a few
years before, such a remarkable development on a shortwave station would have
been noted by only a tiny group of hobbyists. But starting the previous
June—after the first, mysterious outage—a feed of UVB-76 had been made
available online (UVB-76.net), cobbled together by an Estonian tech entrepreneur
named Andrus Aaslaid, who has been enthralled by
shortwave radio since the first grade. “Shortwave was an early form of the
Internet,” says Aaslaid, who goes by the nickname
Laid. “You dial in, and you never know what you’re going to listen to.” During
one 24-hour period at the height of the Buzzer’s freak-out in August 2010, more
than 41,000 people listened to Aaslaid’s feed; within
months, tens of thousands, and then hundreds of thousands, were visiting from
the US, Russia, Britain, the Czech Republic, Brazil, Japan, Croatia, and
elsewhere. By opening up UVB-76 to an online audience, Aaslaid
had managed to take shortwave radio—one of the most niche hobbies
imaginable—and rejuvenate it for the 21st century.
Today, the
Buzzer’s fan base includes Kremlinologists, anarchists, hackers, installation artists, people who believe in extraterrestrials, a former
Lithuanian minister of communications, and someone in Virginia who goes by the
moniker Room641A, a reference to the alleged nerve center of a National
Security Agency intercept facility at an AT&T office in San Francisco. (“I
am interested in ‘listening,’” Room641A tells me by email. “All forms of it.”)
All of them are mesmerized by this bewildering signal—now mostly buzzing, once
again. They can’t help but ponder the significance of it, wondering about the
purpose behind the pattern. No one knows for sure, which is both the worst and
the best part of it.
As you might expect, the
Buzzer’s history is murky. Roughly 30 years ago, it’s said, the Soviets built a
radio station near Povarovo (the accent is on the
second syllable), a 40-minute drive northwest of Moscow. At the time, Leonid
Brezhnev was still alive, the Kremlin presided over an intercontinental empire,
and Soviet troops were battling the mujahideen.
After the Soviet Union collapsed in 1991, it was revealed that Povarovo was controlled by the military, and that whatever
happened there was top-secret.

Shortwave
radio aficionados developed various hypotheses about the role of the station in
Russia’s sprawling, military-communications network. It was a forgotten node,
one theory ran, set up to serve some function now lost deep in the bureaucracy.
It was a top-secret signal, others believed, that transmitted messages to
Russian spies in foreign countries. More ominously, countered another theory,
UVB-76 served as nothing less than the epicenter of the former Soviet Union’s
“Dead Hand” doomsday device, which had been programmed to launch a wave of
nuclear missiles at the US in the event the Kremlin was flattened by a sneak
attack. (The least sexy theory, which posited that the Buzzer was testing the
thickness of the ionosphere, has never enjoyed much support.)
Before Aaslaid’s Internet relay and the events of 2010, the
dedicated trackers of UVB-76 probably numbered no more than a thousand. Some
had been listening in their spare time since the 1980s, holed up in attics,
garages, basements, and cluttered offices. Many spent their days working for
large organizations—insurance companies, telecommunication conglomerates,
militaries, universities. They lived in West Germany, Britain, the Netherlands,
the US. Some hesitated to disclose their locations to
fellow listeners; others used pseudonyms or handles. Before the fall of
Communism, many of them actually believed they were in danger, assuming that
they could be tracked (through technological methods that were never quite
clear) by the same shadowy forces—KGB agents or radio engineers at the CIA or
MI6 or Mossad—that controlled the stations they
obsessed over. The listeners often thought they might have unearthed something
top-secret, that there were files at foreign spy agencies with their names on
them. They loved that they didn’t know what they were listening to and were
fascinated by the unending strangeness of this persistent, mindless,
clandestine, evil beeping.
“It was
thrilling,” says Ary Boender,
57, a financial consultant who lives near Rotterdam, Netherlands. He first
tuned in to UVB-76 in January 1983. He says he didn’t mean to. He was looking
for another station, rolling across the dial, and suddenly he heard the
crackly, wispy beep beep beep.
And stopped. This is how many fans talk about their
discovery of the station: It was late, and they were looking for something
else—a weather channel, a maritime report, some Air Force chatter—when all of a
sudden UVB-76 broke through the ether and they were captivated, unable to stop
listening to the haunting pulse that bleated through the cold and snowy dark
all the way to their receivers. The question they all wanted answered was, what the hell is this? “The fun is and was to find out
who they are and where they transmit from and what the purpose is,” Boender says.
Before the
Internet, shortwave fans knew of one another’s existence largely through niche
publications, whether photocopied newsletters like Monitoring Times or
small-circulation magazines like Popular Communications. (Cover line on the October 1985 issue: “Eavesdropping on Aircraft
Communications!”) If something exciting happened on UVB-76—when there
was an uptick in the duration of the beeps from, say, 1.9 to 2.2 seconds, or
when the timbre of the beeping waxed or shifted, or when there was a rare pause
in the transmission—fans would write in and speculate about possible meanings.
They would clock the frequency of the beeping and listen for discrepancies or
numbers or voices just beneath the veil of sound. They would ferret out other
subscribers to the newsletters they received and other members of the shortwave
radio associations they belonged to and share their findings.
Even today,
listening to UVB-76 is like listening to a world that hasn’t existed for
decades. This feels especially true late at night when you’re in a dark
basement, headset on, enveloped by all the pops and whirs and snippets of
anonymous voices from other signals seeping across the airwaves—”these little
trips into fantasy,” as Room641A puts it, that “happen when you are sitting in
front of your receiver passing by Radio Havana at 3 in the morning.”
Most observers believe that UVB-76
is an idiosyncratic example of what’s called a numbers station, used to
communicate encrypted messages to spies or other agents. Typically, these
stations transmit numbers in groups of five, making it impossible to detect
partitions between words and sentences. The numbers can be decoded using a key
in the possession of the intended listener. Numbers stations are thought to
have existed since World War I, as documented by the Conet
Project, a compilation of recordings that was first released in 1997. (Director
Cameron Crowe, a fan of the Conet Project, used samples
from it in his 2001 film Vanilla Sky.) Drug runners are believed to have
used numbers stations on occasion; so too are the North Koreans, the Americans,
the Cubans, and the British. Indeed, shortwave hobbyists suspect MI6 was behind
the most famous numbers station on the planet, the much-revered Lincolnshire
Poacher.
An online
group calling itself Enigma 2000 (the first part is an acronym for the European
Numbers Information Gathering and Monitoring Association) collects data about
numbers stations around the world. Jochen Schäfer, who heads the group’s German branch, says of
UVB-76, “It’s no typical numbers station, but it is one.” Usually, he says,
numbers stations begin their transmissions with a call sign, then move on to a
specially produced introduction—the Lincolnshire Poacher, for example, got its
moniker because every broadcast kicked off with the first two bars of the
English folk song with the same name—before they start broadcasting numbers.
“This station is different because of its structure,” Schäfer
says. “Most of the time, there is just the buzzing tone… The messages come at
irregular times.”
But this
anomalous format has prompted some UVB-76 listeners to suggest that it is not a
numbers station at all. One former high-ranking European official and longtime
student of Soviet jamming of Western radio stations, known to his fellow UVB-76
fans as “JM,” maintains that the Buzzer’s purpose is to transmit coded orders
to military units within Russia, not to spies outside its borders. JM notes that
most of what has been pieced together about the station’s specs—its frequency
of 4625 kHz, its main 20-kilowatt transmitter, its 5-kilowatt backup
transmitter, and its horizontal-dipole antenna—points to conventional, military
use. Bryan Tabares, a 21-year-old production engineer
in Jacksonville, Florida, agrees and puts forward an even more innocuous theory
to explain the disruptions of 2010: He believes it was merely “pink noise”
manufactured by sound engineers to calibrate audio equipment. That’s all. “Everything
that’s happened points to an equipment upgrade or calibration,” Tabares says.

Boender, the financial consultant
near Rotterdam, says he is now confident that UVB-76 is controlled by the
military. He bases this conclusion on his analysis of known Russian military
stations. That type of sleuthing seems to be a large part of the appeal for him
and other shortwave aficionados. He gives another example: “We discovered a
Russian network in the early ’90s, but it took us a couple of years before we
actually found out who they were. It appeared to be a network of Soviet
embassies, consulates, ministries, and most likely also the KGB and GRU
[Russia's largest foreign intelligence agency]. A number of people around the
globe listened, and we exchanged messages and recordings and analyzed them
until we finally discovered who they were.” He adds, “That’s what makes it
fun.”
It took a 37-year-old computer
engineer in Tallinn, Estonia, to drag UVB-76 into the Internet era. In the
process, Andrus Aaslaid has expanded the station’s
audience in a way that no devoted listener could have anticipated. Aaslaid’s office is the third-floor attic of a stonework
building on a quiet street in the center of the Baltic city. From the kitchen
in the attic, he can see, about 20 feet away, the apartment he shares with his
family, which takes up the top floor of a former boardinghouse built in 1897.
Though Aaslaid isn’t well known internationally,
inside Estonia he’s something of a poster boy for the local tech scene, which
has produced not only giants like Skype but a slew of rapidly growing startups.
In the early ’90s, Aaslaid launched his first
company, LaidWare, providing banks with
ATM-networking systems. Then he ran a firm that was acquired by the quartet
behind Skype. Then he did a stint in Silicon Valley. After that he served as an
adviser to two Estonian economic-affairs and communications ministers,
including Andrus Ansip, the country’s current prime
minister. Like many entrepreneurs, Aaslaid has a
frenetic quality, and he resists convention: He got married to the mother of
his children in 2010, when his daughter was 6 and his son was 4. He has a hard
time staying at a job for more than a year. He dropped out of university after
two months. (“I was already working as a programmer,” he says. “We were the
first wave to learn it hands-on. You didn’t need a degree.”)
Natalia never strays through the wrought-iron fence. On the other side is
the radio tower, and no one, she says, ever goes there.
Aaslaid discovered shortwave radio as
a young boy, and even today, when he talks about the UVB-76 Internet relay, he
sounds a little like a teenager, fascinated by a world he does not quite
understand. He turns on his receiver and we listen for a few minutes to random
sound fragments: a peace activist talking about “rediscovering Hiroshima,” a Russian
newscaster describing carnage in the Gaza Strip, the tail end of a song by Supertramp. “I’ve spent nights just randomly browsing and
sometimes getting really, really drunk,” Aaslaid
says. (His drink of choice is Aberlour A’bunadh, a single-malt Scotch.) “In the era of the
Internet and corporations, people’s lives are so well planned and predictable,”
he says. “In some ways, UVB-76 represents the good kind of unpredictability and
mystery.”
Hooking up
the relay was technologically simple but physically challenging. To make his
antenna, he scrounged up 230 feet of copper-plated wire and in the middle of
the night strung it between the roof of his office and the roof of his
apartment building, going back and forth several times. Then he hooked up his
shortwave scanner to his computer. To handle the streaming audio, he used a
British service provider called MixStream. Several
weeks later, he upgraded to a custom-built magnetic loop antenna and swapped
out his scanner for a software-based radio.
Over the
next six months, 200,000 listeners from scores of countries dropped in. Like
any good shortwave junkie, Aaslaid watches the
watchers—noting that, after the US, the number-two source of interest is
Russia. Aaslaid says he’s received numerous email
messages from artists and musicians who said the Buzzer had inspired them.
X-Ray Press, a “math rock” band in Seattle, released an album this year called
UVB-76, which features Buzzer-like buzzing in the background. Sherri Miller and
Mario Fanone, two electronic musicians in Buffalo,
New York, did them one better by naming their band UVB-76 and starting each
live set with a brief sample of the Buzzer. Fanone
plays a Casio digital guitar and a trumpet, while Miller generally plays a Korg Electribe, though sometimes
she plays a vacuum cleaner, running its whoosh through an effects pedal to
enhance its sound.
Aaslaid remains fascinated. “It has
transmitted voice messages, it has been mute, its frequency has been hijacked
by pirates, it has run through the maintenance with all the related voice
messages and test runs, it’s had loads of strange noises, transmitted 24 hours
with extremely high power all around the world,” writes Aaslaid,
in a typically rapturous email about just what the station means to him.
“Therefore I have fallen for it!” When I ask him why anyone cares about UVB-76,
and why they should care about shortwave in general, he replies by
invoking the universal connectivity that this primitive technology allows, even
in places far from a cell tower. “Imagine somebody with a Morse key or a
reel-to-reel tape deck in the middle of the Namibia desert, running a shortwave
transmitter off a diesel generator and sending music or messages toward the
ionosphere. In the middle of the night, it does not get any more spiritual than
that.”
A new intrigue about UVB-76—or MDZhB—is the question of its location. Soon after the
upheavals of August and September 2010, with all the stopping and starting and
knocking and whispering, shortwave listeners reported another remarkable shift:
The station’s position seemed to have moved. JM, the former European official,
has since helped trace its rough location to near the town of Pskov, close to
Russia’s border with Estonia. But no one has been able to triangulate exactly
where the broadcast is coming from. Ary Boender theorizes that the move was related to a Russian
military reorganization that took place that September, when the Moscow and
Leningrad military districts were merged to form a new command center in St.
Petersburg—which would explain why UVB-76, too, might have migrated hundreds of
miles northwest. For the foreseeable future, though, the site of the
transmitter has been added to the long list of its enduring mysteries.
Today, the
mini military city in Povarovo, from which the cipher
broadcast for so many decades, is nearly abandoned. The surrounding village is
a gray-brown tapestry of Communist apartment buildings, recently built dachas,
and babushkas hawking honey and cucumbers. Around the voyenni
gorodok,there
are gates and walls and signs—military vehicles only—but no guards or
electrified fences, and the gates are not locked. The only activity is near the
housing blocks filled with the wives and children and grandchildren of Soviet
veterans, living and dead. “This was like paradise,” says one resident,
Natalia, whose late husband, Sergey Nikolayevich, served as driver to the
commander of the voyenni gorodok. When asked about the looming wrought-iron
fence roughly a hundred feet from the entrance to her apartment building, she
says she never strays through its gates. On the other side is the radio tower,
and no one, according to Natalia, ever goes there.
The one-lane
road that leads to the tower stretches about a quarter mile past a handful of
empty buildings and a thick pine forest. A chain-link fence, supported by stone
posts capped with moss, surrounds the tower. Between 100 and 150 feet tall,
it’s red and white and rusting, with three or four satellite dishes attached to
it. Next to the tower are a blue shed, a green metal hut stuffed with wires and
electrical equipment, and an ancient stone structure that’s also overgrown with
moss. And there appears to be a large underground facility: The muddy pitch on
which the tower stands is riddled with metal cylinders (presumably ventilation
shafts) rising out of the ground, and there is a very small pink building that
looks like the entrance to a descending staircase. Also, there’s a door that’s
partially ajar on the side of the stone structure. If you open it and peer
inside, you’ll see a black hole where there must have been a ladder several
years or decades ago, and if you drop a rock in this hole, it will take about a
second to reach the bottom—whatever is down there is at least 32 feet
belowground.
Just beyond
the chain-link fence and the radio tower is another building, which is one
story and also pink. There is a large antenna outside, and a tree, and a
barking mutt leashed to a cable that’s strung from the tree to the building.
The setup is such that if you were to approach the front door, you would enter
the jurisdiction, so to speak, of the dog, which barks endlessly and
ferociously, as if he has been beaten.
The front
door appears to be locked. There is no light on inside; no one comes in or out.
But someone has been here. The dog, after all, must be fed.
