The Buzzer operates around 4625 kHz
VerifiedPriyom’s profile lists the frequency as 4625 kHz and the station as active, with a channel marker used when no other traffic is being sent.

VerdictUnresolved
The signal is real. The meaning is still sealed.
What is documented
The station is publicly monitored around 4625 kHz and is associated in monitoring records with the names The Buzzer, UZB-76, MDZhB, ZhUOZ, ANVF, and NZhTI.
What remains opaque
The voice traffic follows disciplined formats, but outsiders have not publicly decoded the operational payload or received an official explanation of purpose.
What this file establishes
The signal
A persistent channel marker is heard on 4625 kHz, with public monitoring records placing the station’s origins in the late Soviet period and its current activity in the Russian present.
The architecture
Priyom identifies standardized traffic families including Monolith-type messages, Uzor-type messages, and command messages.
The callsign trail
The public label “UVB-76” is widely treated as a mistranscription of UZB-76. Later public callsign eras include MDZhB, ZhUOZ, ANVF, and NZhTI.
The recent surge
Meduza reported 24 messages on December 11, 2024. A later monitoring report described about 20 coded transmissions on June 24, 2026.
Born in the Soviet shadow, still transmitting in the Russian present
The sequence of material events
1970s-1980s
Public monitoring histories place early Buzzer activity in the late Soviet period, with older marker tones preceding the familiar buzz.
Around 1990
The familiar buzzer-style channel marker replaces earlier marker sounds, according to technical monitoring summaries.
September 2010
Priyom states that the station shifted from the former Moscow Military District context into the Western Military District structure after military reorganisation.
December 2020-present
NZhTI becomes the dominant public callsign era in monitoring records, though other callsigns can appear.
The strange part is not the buzz. It is the procedure beneath it.
Monolith-type traffic
The dominant public message family: callsign repetition, an identification group, codeword material, and numerical blocks. Its repetition over years indicates a maintained procedure.
Uzor and command messages
Priyom identifies additional traffic families, reinforcing that The Buzzer is part of a communications system rather than a single unexplained noise.
Open microphone oddities
Historic monitoring has captured background noises and accidental transmissions, supporting the idea that equipment and local operators are involved rather than a purely automated mystery machine.
Meaning remains closed
The literal Russian codewords are publicly audible, but their operational purpose is not. A word sounding ominous or ordinary does not prove what the message orders.
The surge years sharpen the mystery but do not solve it
The sequence of material events
December 11, 2024
Meduza reported that UVB-76 transmitted 24 messages in one day, describing it as a near-record or historically verbose burst based on monitoring-community reporting.
January 2026
Shortwave monitoring reports described Swan Lake and cryptic code activity on or around the frequency, renewing public speculation while not proving a decoded meaning.
June 24, 2026
A recent monitoring report described about 20 coded voice messages between 06:11 and 14:10 UTC, including NZhTI and other callsigns. The report explicitly noted no verified evidence linking the literal codewords to real-world events.
Claim status
Voice traffic follows structured formats
VerifiedTechnical monitoring records identify recurring message families and consistent elements such as callsigns, identification groups, codewords, and numbers.
The station is officially explained
ContestedThe military-command-network interpretation is strong, but the public record still lacks an official explanation of purpose, recipients, or message content.
The Buzzer is a nuclear doomsday trigger
UnprovenThe Dead Hand or doomsday-station theory remains part of the folklore. Public monitoring evidence does not prove that role.

V — The 2024–2026 Surge
What reignited mass interest was not the standard buzzing. It was the surge in abnormal activity.
In December 2024, Meduza reported that the station sent 24 messages in a single day, described by monitors as the most verbose broadcast in its history.
The words ranged from recognisable Russian terms to strings that looked meaningless to outsiders. The station's callsign environment fed the attention as well, with NZhTI appearing frequently in the modern phase while observers tracked rising traffic against a background of war, military tension, and renewed state secrecy.
Then came the stranger breaks. Late 2025 and early 2026 produced reports of music intrusions, odd sounds, and non-standard audio making its way onto the frequency.
In January 2026, the station briefly aired Tchaikovsky's Swan Lake before returning to form.
That does not prove a hidden launch protocol. It shows how exposed legacy systems can become to interference, hijacking, opportunistic intrusion, or simple technical disorder.
It also shows why the public keeps over-reading the station. Every anomaly feels like a clue, even when it may be nothing more than a breach, a jam, a glitch, or a test.
January 2026 — Swan Lake incident: the appearance of Tchaikovsky on a Russian military shortwave frequency carries its own historical weight. Swan Lake was broadcast on Soviet state television during the 1991 coup attempt as a holding signal while the plotters consolidated power. Whether the 2026 broadcast was interference, a test, or something deliberate has not been established.

Evidence Ledger
Registered claims and their evidential status
UVB-01 — Priyom’s monitoring profile records UVB-76 observations around 4625 kHz.
Verified
The finding is limited to the cited record and the stated evidence boundary.
UVB-02 — The Buzzer Primer documents observed signal and message characteristics while leaving the station’s purpose unresolved.
Verified
The finding is limited to the cited record and the stated evidence boundary.
UVB-03 — Meduza reports dated UVB-76 activity and competing explanations without establishing an official mission.
Verified
The finding is limited to the cited record and the stated evidence boundary.
UVB-04 — A monitoring report describes a similar signal observed on 4810 kHz.
Verified
The finding is limited to the cited record and the stated evidence boundary.
Final Assessment
Verdict: UVB-76 should be treated as an active, state-linked communications mystery with substantial monitoring evidence and a hard evidentiary wall around message meaning. The file remains open.
