Far beyond the repetitive buzzing that made it famous, UVB‑76 is also known for a series of enigmatic transmissions that broke the usual pattern.
Over the decades, several notable UVB‑76 cases have been recorded: coded voice messages, mysterious interference, callsign changes, and even pirate signal takeovers.
In this post, we’ve compiled the most intriguing episodes ever documented — the ones that shifted public perception of the station and continue to attract attention from listeners and experts around the world.

UVB‑76: The Mysterious Buzz That Puzzles the World
What Makes a UVB‑76 Event Notable?
UVB‑76 usually operates in a monotonous way, with its constant buzzing. Therefore, any deviation — no matter how small — stands out immediately.
When the sound changes, when someone speaks, or when silence suddenly takes over, seasoned listeners know something out of the ordinary is happening.
For this reason, enthusiasts have monitored the signal for decades. These recordings were crucial in transforming isolated rumors into well-documented cases. After all, once a recording or confirmed transcript exists, a story gains credibility.
Here are the 10 most notable events ever recorded.
The 10 Most Notable UVB‑76 Cases
1. First Recorded Voice (1997)
On December 24, 1997, UVB‑76 startled listeners by interrupting its buzzing with a voice message. A man said:
“Ya UVB-76, Ya UVB-76. 180 08 BROMALIT…”
The recording was made by a radio enthusiast and became one of the first concrete proofs that there were human operators behind the repetitive sound.
Moreover, the use of the name “UVB‑76” reinforced the station’s identification.
2. Accidental Phone Transmission (2003)
In 2003, an unexpected leak revealed the sound of a ringing phone, followed by a conversation between two men discussing a delivery and an address.
Although brief, this transmission was enough to confirm that the station was connected to a phone line — something long suspected but never clearly proven until then.
3. Names and Codes Broadcast (2006)
On September 21, 2006, UVB‑76 transmitted a long message containing Russian names and number sequences:
“Mikhail Dmitri Zhenya Boris… 74 14 35 74…”
This event was significant because it reinforced the idea that the transmissions follow a standardized military format.
In addition, the use of names suggested the messages were intended for specific individuals, possibly agents.
4. Voices Behind the Buzz (2010)
In June 2010, listeners noticed voices in the background of the buzzing, as if someone had accidentally left a microphone open.
It was possible to hear Russian phrases, laughter, and even the sounds of objects being moved.
This incident intensified suspicions that UVB‑76 was operating from an active military facility.
5. Complete Silence (August 25, 2010)
On August 25, 2010, the buzzing stopped entirely for about 24 hours. In place of the usual signal, there was complete silence.
It was one of the most intense moments for those who follow the station.
Shortly afterward, a new coded voice transmission aired — further deepening the mystery.
6. Pirate Signal Takeover (2011)
In 2011, UVB‑76’s frequency was hijacked by an unidentified signal that broadcast techno music, sound effects, and a countdown.
The event shocked the radio community, as it suggested that someone had managed to access — or at least deliberately interfere with — the frequency.
7. Callsign Changes (2010–2011)
Until 2010, the station used the callsign UVB‑76. That year, it switched to MDZhB. Later, others emerged, such as ZhUOZ and ANVF.
This change reinforced the theory that UVB‑76 is just one of several stations with similar functions.
It also confirmed that there is some form of active management behind the transmissions.
8. Broadcast During Protests (2013)
In 2013, during protests in Moscow, UVB‑76 broke from its usual pattern again, transmitting messages with names and codes.
The timing coincided with political tensions in the country, leading to speculation that the station might be linked to internal alert protocols.
9. Interval Tone Tests (2015)
In 2015, UVB‑76 broadcast test sounds in an unusual format: tones alternating with long periods of silence.
Even for a station known for its strange buzzing, this was an outlier.
Some analysts suggested UVB‑76 was undergoing technical updates or operational redirection.
10. Parallel Transmissions (Since 2020)
In recent years, stations like “S28” have been identified as operating with very similar patterns to UVB‑76.
Some even use the same voice style, nearby frequencies, and matching message structures.
This strengthens the hypothesis that UVB‑76 is part of a larger network of Russian military stations.
What Do These Events Reveal About UVB‑76?
Each of the cases listed here represents a break in UVB‑76’s pattern — which is meaningful in itself.
Even so, the station remains on the air, buzzing endlessly and defying simple explanations.
While some theories suggest routine military use, others point to tests, propaganda, or strategic deterrence.
Ultimately, what makes these notable UVB‑76 cases so fascinating is the contrast between the bizarre events and the station’s otherwise monotonous routine.
