As we charge into 2015 and new cold war relations heat up between Russia and the United States, a mysterious Russian radio station which has broadcast the same super-creepy signal for 24 hours-a-day, 7-days-a-week, and 365-days-a-year FOR THE LAST 40 YEARS is getting a lot of new interest due to its' unknown purpose, with some claiming it is Russia's 'nuclear trigger' while others say it's a continuous broadcast into outer space to communicate with extraterrestrials. The 1st video, a brand new one from Strange Mysteries, tells us all about the mysterious UVB-76, looking into what it's true purpose might be while telling us about the day in 2010 when it stopped broadcasting for a day, for the first time since 1982!

The 2nd video below shares what can only be called an ultra-creepy message from UVB-76 that came through on August 23, 2010, one of the few times that the monotonous tone of 'the buzzer' has been broken to broadcast its message to Russia and much of Europe as shown in the screenshot below videos that shows how far UVB-76 broadcasts. The message broadcast on August 23, 2010 in the 2nd video below is generating all kinds of comments and interest.

What is this mysterious 'buzzer' signal and why the messages? It has been determined that this radio station is owned and operated by the Russian government/military. Why the continuous monotonous buzz; do you think it's a message to aliens or, if the signal is suddenly broken, is that the trigger for nuclear annihilation?  SOURCE

The Buzzer

UVB-76, also known as The Buzzer, is the nickname given by radio listeners to a shortwave radio station that broadcasts on the frequency 4625 kHz. It broadcasts a short, monotonous About this sound buzz tone (help·info), repeating at a rate of approximately 25 tones per minute, for 24 hours per day. On very rare occasions, the buzzer signal is interrupted and a voice transmission in Russian takes place. The first reports were made of a station on this frequency in 1982. Its origins have been traced to Russia, and although several theories with varying degrees of plausibility exist, its actual purpose has never been officially confirmed and remains a source of speculation.

UVB-76 August 23, 2010 Voice Message

This is the most COMPLETE and CLEAREST UVB-76 message recording. We hear EVERYTHING perfectly. The nature of these messages is unknown, but it was once said that they are to make sure that the receiving station is prepared. This could mean that the morse code messages are the real messages, and these are just tests, but that's what I think.

The station is commonly referred to as the Buzzer among English-speaking radio listeners, while Russian listeners refer to it as жужжалка (žužžalka) – "the buzzer". Its official name is not known, although some of the voice transmissions have revealed names which may be call signs or another form of identification. Up until September 2010, the station identified itself as UVB-76 (Cyrillic: УВБ-76), and it is still often referred to by that name. In September 2010, the station moved to another location, and it has used the identification MDZhB (Cyrillic: МДЖБ, phonetic spelling "Mikhail Dmitri Zhenya Boris") from then onwards. It has been suggested that the correct identification until September 2010 was actually UZB-76 (Cyrillic: УЗБ-76), and that the Cyrillic letter Ze (З) had been misheard as the letter Ve (В). However, it is still referred to as "UVB-76" by most people. Although the station, by and large, has used these two codes at the beginning of most voice transmissions, a few voice messages have used other identification codes. This makes it uncertain whether the names are actually the call sign of the station, or some other identifying code.

The station transmits using AM with a suppressed lower sideband (R3E), but it has also used full double-sideband AM (A3E). The signal consists of a buzzing sound that lasts 1.2 seconds, pausing for 1–1.3 seconds, and repeating 21–34 times per minute. Until November 2010, the buzz tones lasted approximately 0.8 seconds each. One minute before the hour, the repeating tone was previously replaced by a continuous, uninterrupted alternating tone, which continued for one minute until the short repeating buzz resumed, although this no longer occurs since June 2010.

The Buzzer has apparently been broadcasting since at least 1982 as a repeating two-second pip, changing to a buzzer in early 1990. It briefly changed to a higher tone of longer duration (approximately 20 tones per minute) on January 16, 2003, but it has since reverted to the previous tone pattern.

Voice messages

On rare occasions, the buzzing sound is interrupted and a voice message is broadcast. These messages are usually given in Russian by a live voice, and follow a fixed format.

Until 2010, voice messages were thought to be very rare. Examples of such messages include:

At 2100 UTC on December 24, 1997: "Ya UVB-76, Ya UVB-76. 180 08 BROMAL 74 27 99 14. Boris, Roman, Olga, Mikhail, Anna, Larisa. 7 4 2 7 9 9 1 4."
At 0418 UTC on December 9, 2002: "UVB-76, UVB-76. 62 691 IZAFET 36 93 82 70"
At 0757 UTC on February 21, 2006: "UVB-76, UVB-76. 75-59-75-59. 39-52-53-58. 5-5-2-5. Konstantin-1-9-0-9-0-8-9-8-Tatiana-Oksana-Anna-Elena-Pavel-Schuka. Konstantin 8-4. 9-7-5-5-9-Tatiana. Anna Larisa Uliyana-9-4-1-4-3-4-8."
During 2010, listeners reported increased activity of the station, which spurred on further monitoring and allowed listeners to "catch" more of the messages which would have otherwise gone unnoticed. On June 5, 2010, UVB-76 went silent for approximately 24 hours, resuming the normal buzzing pattern on the morning of June 6. At 1335 UTC on August 23, 2010 a voice message was broadcast:

"UVB-76, UVB-76. 93 882 NAIMINA 74 14 35 74" (Recording of August 23rd transmission)
Two days later, on August 25 at 0713 UTC, the signal went silent again, followed by a series of thumping sounds apparently in the same room as the open microphone. It was followed by a hail of electronic noise, which then faded again into the buzzer broadcast. Later that same day, voices were heard conversing loudly behind the buzzer. Another voice broadcast was made at 1648 UTC on September 7:

"Mikhail Dmitri Zhenya Boris. Mikhail Dmitri Zhenya Boris. 04 979 D-R-E-N-D-O-U-T. T-R-E-N-E-R-S-K-I-Y."
It was the first of 25 voice messages that would be broadcast by September 30, with another 56 to follow between October and December. Each of these, with one exception on September 10, replaced the familiar "UVB-76" call sign with "MDZhB", suggesting that the station had changed call signs. A further 14 voice messages followed between January 5 and February 5, 2011.

On March 18, 2014, less than 24 hours after Crimea voted to join the Russian Federation, a new voice message was recorded:

"T-E-R-R-A-K-O-T-A. Mikhail Dimitri Zhenya Boris. Mikhail Dmitri Zhenya Boris. 81 26 T-E-R-R-A-K-O-T-A."
The message was repeated again followed by the buzzer resuming.

On December 3, 2014 at 22:44, the buzzer tone pitched down over about 7 seconds, making a 'dying' noise, and went silent afterwards, but the buzzer resumed about 10 minutes later.

Unusual transmissions

Frequently, distant conversations and other background noises have been heard behind the buzzer, suggesting that the buzzing tones are not generated internally, but are transmitted from a device placed behind a live and constantly open microphone. It is also possible that a microphone may have been turned on accidentally. One such occasion was on November 3, 2001, when a conversation in Russian was heard:

"Я – 143. Не получаю генератор." "Идёт такая работа от аппаратной." ("I am 143. Not receiving the generator (oscillator)." "That stuff comes from hardware room.").
On November 11, 2010, intermittent phone conversations were accidentally transmitted and were recorded by a listener (at 1400 UTC) for a period of approximately 30 minutes. These conversations are available online, and seem to be in Russian. The phone calls mentioned the "brigade operative officer on duty", the communication nodes "Debut", "Nadezhda" (Russian for "hope", both a noun and a female name), "Sudak" (a kind of river fish and also a town in Crimea) and "Vulkan" (volcano). The female voice says "officer on duty of communication node Debut senior ensign Uspenskaya, got the control call from Nadezhda OK".

Location and function

The purpose of the station has not been confirmed by government or broadcast officials. However, the former Minister of Communications and Informatics of the Republic of Lithuania Rimantas Pleikys has written that the purpose of the voice messages is to confirm that operators at receiving stations are alert. Other claims are that the broadcast is constantly being listened to by military commissariats.

There is speculation published in the Russian Journal of Earth Sciences which describes an observatory measuring changes in the ionosphere by broadcasting a signal at 4625 kHz, the same as the Buzzer. However, this would not explain the voice messages.

It is also speculated that the voice messages are some sort of Russian military communications, and that the buzzing sound is merely a "channel marker" used to keep the frequency occupied, thereby making it unattractive for other potential users. The author does not explain the continued expenditure on this public transmission for such a small trickle of usable information, particularly with the advent of cheap, reliable, secure communication via the Internet. It is worth noting that this transmission has been maintained consistently and at high power for over 30 years.

There are two other Russian stations that follow a similar format, nicknamed "The Pip" and "The Squeaky Wheel". Like the Buzzer, these stations transmit a signature sound that is repeated constantly, but is occasionally interrupted to relay coded voice messages.

The former transmitter was located near Povarovo, Russia at 56°5′0″N 37°6′37″E which is about halfway between Zelenograd and Solnechnogorsk and 40 kilometres (25 mi) northwest of Moscow, near the village of Lozhki. The location and callsign were unknown until the first known voice broadcast of 1997. In September 2010, the station's transmitter was moved to near the town of Pskov. This may have been due to a reorganization of the Russian military. In 2011 a group of urban explorers explored the abandoned buildings at Povarovo. They claim that it is an abandoned military base. A radio log record was found, confirming the operation of a transmitter at 4625 kHz.

Has the Internet solved the mystery of this 40-year-old radio signal?

Volume dials were turned up, computers began recording, forum posts were hastily typed. Something big was happening.


For the first time in a history that stretches back nearly 40 years, the mysterious Russian radio signal popularly known as UVB-76 had issued an order. On Jan. 24, 2013, it was heard clearly by its legion of fans:

Command 135 initiated

The radio signal that occupies 4625 kHz has reportedly been broadcasting since the late 1970s. The earliest known recording of it is dated 1982. Ever since curious owners of shortwave radios first discovered the signal, it has broadcast a repeating buzzing noise. Every few years, the buzzer stops, and a Russian voice reads a mixture of numbers and Russian names.

A typical message came hours before Christmas day, 1997:

“Ya UVB-76, Ya UVB-76. 180 08 BROMAL 74 27 99 14. Boris, Roman, Olga, Mikhail, Anna, Larisa. 7 4 2 7 9 9 1 4”

Instead of shutting down with the fall of communism in Russia, UVB-76 became even more active. Since the millennium, voice messages have become more and more frequent.

It’s easy to dismiss the signal as pre-recorded, or a looping tone. But what listeners quickly realized was that UVB-76 is not a recording. The buzzer noise is generated manually. The reason for hearing telephone conversations and banging noises in the background of the signal is that a speaker creating the buzzer is constantly placed next to the microphone, giving the world an eerie insight into whatever cavern the signal originates from.

The modern popularity of UVB-76 can be traced to /x/, 4chan’s non-archiving message board devoted to discussion of paranormal activity and unexplained mysteries. Just as 4chan created memes like Pedobear and Rickrolling, the online image board served to bring UVB-76 before the eyes of a host of Internet users.

Online chatter about the signal increased in 2010 as bizarre broadcasts were issued on an almost monthly basis. Snippets of Swan Lake were played, a female voiced counted from one to nine, a question mark was transmitted in Morse code, and strange telephone conversations were overheard by the receiver.

Since October 2010, the station has changed location. The flurry of activity and voice messages preceded the most important development in the signal since it began broadcasting in the 1970s. It seems likely that the heightened activity of 2010 was related to the establishment of the signal in a new location. The new call sign was read out after the move: “MDZhB”.

Previous triangulation efforts had led to the discovery of the transmitter for UVB-76: a Russian military base on the outskirts of Povarovo, a small town 19 miles from Moscow.

After the station changed location, two groups of urban explorers and UVB-76 followers travelled to the remote Russian town in an attempt to visit the military bunker that the signal had originated from for over 30 years. When they reached the town, a local man told them about the storm of 2010. One night a dense fog rolled in, and the military outpost was evacuated within 90 minutes.


After making their way across the site and avoiding the guard dog stationed outside, the groups found the bunker and military buildings in a state of abandonment. Possessions and equipment were strewn across the base. Icy water had filled the bunker, yet clues were still to be found inside. One group described the Povarov military bunker as "a quiet and lonely dark place, something like a maze with lots of corridors and rooms."


A book was found that contained a log of messages sent by UVB-76. The ethereal signal that had fascinated the world for years now had a physical presence, along with confirmation that it had been run by the Russian military.


But the mystery continues to this day. Sporadic voice messages are still emitted. Legions of listeners tune in via radios and online streams every day. A file can be downloaded at this link that allows followers to listen to UVB-76 in iTunes.

Along with a renewed interest in studying and archiving the broadcasts of UVB-76, multiple triangulation attempts have been made to try and ascertain the new location of the signal. Unlike before, it seems that UVB-76 is emanating from multiple transmitters across Russia. Triangulation has given rise to three possible locations.

One possible location is the small Russian village of Kirsino, which has a registered populace of just 39 people. One signal can be traced here. But this isn't the fan-favorite location.


Near to the Estonian border lies the Pskov Oblast. This is currently the most likely source of UVB-76, due to the multiple triangulation attempts that lead here.

Recently a new theory has been the cause of much discussion amongst the followers of UVB-76. Could the signal be related to the Russian Government radio channel Voice Of Russia? One location that appears during triangulation attempts is very close to a transmitter array southeast of Kolpino that is reportedly used by the Russian government to transmit state radio across Russia.

As UVB-76 settled into the new location, Dance of The Little Swans from Swan Lake was played. Instrumental passages from Swan Lake are a favorite of Voice Of Russia.

The radio array that offers an intriguing link between UVB-76 and the Russian government

While Internet followers may have discovered the location of the old signal, the purpose of UVB-76 remains a mystery. As with any unexplained mystery, conspiracy theories abound, some more credible than others.

The closest thing to an official explanation for the signal’s purpose comes from an academic paper published by the Borok Geophysical Observatory. This state-funded organization describes itself as a "branch of the Federal state budgetary institution of science." They explain that the signal originates from an observatory using the 4625 kHz frequency to measure changes in the ionosphere.

This does not explain the military bunker, or the voice messages. Nor does the paper detail how successful the research has been. A signal on the 4625 kHz frequency would have suffered from extreme interference, rendering it nearly unusable for researching the ionosphere.

The fan-favorite conspiracy is that UVB-76 is the audible version of Russia’s "Dead Man Switch" system. In the case of a nuclear strike that cripples Russian military command, the automated system will launch a counter-strike. While it’s likely that Russia does possess such a system, it’s fanciful to think that this humble buzzing sound is the noise of our impending nuclear apocalypse.

The most credible explanation of UVB-76’s purpose is that it is a military communication system operating across western Russia. The coded messages are announcements for various military districts, enabling a simple means of communicating with multiple units at the same time. As for the repeating buzzing noise, this is thought to be a channel marker that exists to discourage others from using the same frequency.

An image posted on Russian Wikipedia seems to confirm the military communication theory. A small, framed piece of paper in an administration and enlistment office of the Russian army refers to 4625 kHz, the broadcasting frequency of UVB-76. With this so prominently displayed, it’s possible to confirm that the signal is not a "Dead Man’s Switch," nor is the signal intended to be a secret.

The Internet has, for decades, been listening to the internal communication network of the western division of the Russian armed forces.


While the mystery of UVB-76 may have been solved, its legion of followers and obsessives will continue to listen. Thousands of people across the world tune into the signal, hoping to catch one of the ethereal voice messages.

For those in the know, it’s a bemusing social phenomenon. But for the residents of 4chan’s /x/ board and the radio scanner fans, UVB-76 is far more than a communications network. For them, it’s a sign of the forthcoming apocalypse, it’s an international spy network, it’s a secret Russian space experiment.

Whether you believe the theories or not, there’s no denying the thrill that comes with hearing the distorted voice messages of UVB-76.
