# UVB-76 Mystery
UVB-76 Mystery refers to the online fascination with a Russian shortwave station on 4625 kHz that has broadcast an unexplained repeating buzz tone since the late 1970s, punctuated by rare Russian voice messages reading numbers and names. Online attention swelled in 2010 when strange transmissions sparked 4chan and Reddit speculation, turning the station into one of the internet's longest-running real-world mysteries.
## Origin
The station's own origin predates its internet life by decades. According to Priyom, a radio enthusiast group that tracks numbers stations, the earliest reports of UVB-76 transmissions range from 1976 to 1982, and the oldest surviving recording was captured by Dutch listener Ary Boender in January 1982[2]. The first clearly documented voice message was logged by Polish listener Jan Michalski on December 24, 1997, reading "УЗБ-76 180 08 БРОМАЛ 74 27 9914"[4].
The internet-meme catalyst came much later. Michalski set up a Geocities page documenting the station on November 14, 2001[4], but UVB-76 only broke into wider online attention around 2010 after a cluster of oddly frequent broadcasts drew in 4chan's /x/ paranormal board[1]. From there it jumped to Reddit and mainstream tech blogs.

## Overview
UVB-76, nicknamed The Buzzer, is a Russian shortwave station on 4625 kHz that pumps out a monotonous buzzing tone around the clock, broken every so often by a Russian voice reading strings of numbers and names[1]. Listeners figured out early that the buzz isn't a loop. The tone is produced by a speaker sitting next to a live microphone, which is why hobbyists have caught the occasional footstep, telephone call, or scrap of conversation bleeding through[1].
The online version of the mystery works less like a meme format and more like a decades-long group puzzle. Shortwave listeners run 24/7 recordings, forum threads light up whenever a new voice message airs, and users on 4chan's /x/ and /k/ boards swap theories ranging from a nuclear Dead Man Switch to a boring Russian military channel[1][2]. An academic paper from the Borok Geophysical Observatory even argued the signal is tied to ionospheric research[3], a claim that most enthusiasts reject.
Typical voice messages, like the 1997 broadcast "Ya UVB-76, Ya UVB-76. 180 08 BROMAL 74 27 99 14," are what fans actually quote and share[1]. The format of the "meme" is really the chase: a buzz, a sudden voice, a date, and a wave of speculation online.
## How It Spread
UVB-76 crossed from radio-hobbyist niche into general internet curiosity in 2010. On August 25 of that year, Redditor Quady posted the UVB-76 Wikipedia entry to r/technology, where it pulled in more than 1,700 upvotes and 580 comments before being archived[5]. Weeks later the station went quiet, moved from its base near Povarovo, and reappeared under the call sign MDZhB[1]. On November 11, 2010, an hour-long phone conversation leaked through the open mic, giving listeners a rare peek inside the transmitting room[1].
Mainstream coverage followed. Wired UK ran a feature on the station in October 2011[6], and in 2012 Redditor bottlebob32 hosted an r/IAmA about visiting the abandoned Povarovo base, posting photo galleries from inside the derelict facility[7]. The Russian urban-exploration blog Kwasd published its own photo-report of the site in March 2012, including what the group said was a log book of broadcast messages[8]. On October 12, 2012, a 4chan /k/ thread documented a run of strange transmissions aired that month[9].
The audience kept growing through 2013 and 2014. On January 25, 2013, the station aired the unusual order "Command 135 initiated" ("OBYaVLENIYA KOMANDA 135")[1]. The Kernel ran a long feature in August 2013 covering the online fandom and newer suspected transmitter sites near Kirsino or Kolpino[1]. Less than ten hours after the Crimea annexation vote on March 18, 2014, the station read out the message "T-E-R-R-A-K-O-T-A. Mikhail Dmitri Zhenya Boris. 81 26 T-E-R-R-A-K-O-T-A," instantly becoming the most-discussed broadcast of the year[1].
## How to Use
There's no image template to remix. People "use" UVB-76 by tuning in on 4625 kHz or a web SDR, posting timestamped recordings when a voice message airs, and comparing logs on sites like Priyom or r/numberstations. New transmissions typically trigger forum threads speculating about meaning, location, and timing against world events.
