The following chart represents a graph of MDZhB’s (formerly UVB-76) transmission times. This was done by taking time information of all known MDZhB transmissions from 11 September 2010, to 20 January 2011. There have been 80 transmissions in that 131-day timeframe, averaging out at about one transmission every other day. The transmission times were rounded to their nearest ten minutes to simplify the representation.
As you can see MDZhB, broadcasting on 4625 khz, has been transmitting the majority of its broadcasts between the times of 12:50 and 15:20 UTC. If you want to catch a live broadcast, your best chance is to listen within that 2.5-hour timeframe.
Data from danix111’s UVB-76 archives.

There appear to have been a few transmission in the past month with different callsigns. On September 8 2011, a year after UVB-76 changed its callsign to MDZhB, it transmitted a message using another new callsign: 94ZhT. It is unknown yet whether there is any significance to this change.
Here is the transmission:

Just put up a short post analysing the transmission times of MDZhB/UVB-76.
Summary: tune in between 12:50 and 15:20 UTC for the best chance to catch a broadcast.

On the 11th at exactly 1400 UTC, a series of conversations were broadcast between different people on the UVB-76 frequency. It is not yet known where this transmission originated from, although the buzzer can still be heard faintly in the background. Either someone made a mistake, or it’s an unrelated or pirate transmission over UVB-76’s frequency.
A full translation of these conversations is not yet available (feel free to post one), although they appear to be military in nature.

A few guys (Webweasel, Presentedin4D and danix111) from the UVB-76 IRC channel have started a podcast. Here is the first episode:
Fri, 05 Nov 2010 10:08:45 +0000
There have been a number of transmissions since my last post, in fact too many to summarize here. Buzzer has since stopped, however some counting/unknown beeps have been heard. The beeps are interesting as nothing of that kind has been heard so far.

There hasn’t been much to report on recently. Unfortunately the interest in UVB-76 has waned recently, as the mystery of its silence has died down. It’s believed that the frequency is now being used to transmit messages from another relay.
I’ll update this page when something significant happens. I encourage the readers who actively follow UVB-76 to continue posting updates in the comments (many people visit this page for updates).
For those who ever feel nostalgic about the summer of mystery, there’s always UVB-76 Forever!

Here are audio clips of the recent transmissions:
Laid at the UVB-76 Internet Repeater has posted an update on recent events. Here’s one section of that post I think is important to note:
“It has been already disputed that UVB-76 may have changed to that callsign permanently […] As far as communication dispatches seem to be built up, the transmission site (and the frequency associated) is a separate entity from the party what actually airs the “content”. Therefore in any moment can someone decide that particular transmission site will now service another “content provider” and so will be. In that context, MDZhB is now simply using the same transmission unit as UVB-76.”

Based on some comments at the bottom of the page (thanks Jan), apparently there have been some reported transmissions. I haven’t yet been able to confirm these from a secondary source…
Buzzer is currently off.
Thu, 23 Sep 2010 20:12:00 +0000
There have been a few transmission in the past couple days. Unfortunately no recordings or transcriptions are currently available. Other than that the buzzer has been operating more or less ceaselessly.
This evening the buzzer stopped, and the carrier signal has also disappeared.
Sun, 19 Sep 2010 18:25:48 +0000
One transmission today.
MDZhB 75476 Prizmatin 8087 6428 Khrizopraz 0621 5018
Sun, 19 Sep 2010 15:36:26 +0000
Another transmission yesterday. The transmissions from the so-called MDZhB appear quite frequent with 1-2 transmissions daily. What the connection is with the original UVB-76 – apart from the constant buzzer – is unknown. Perhaps the station has been re-purposed to broadcast these coded messages once a day.
MDZhB 2551 BRIZ 2934 7683

A combined stream of the WinradHD waterfall with audio (USB) are now available on Justin.tv.
There have been two supposed transmissions today (check comments for initial details).
First transmission at 11:52 UTC:
MDZhB 19 620 Priroda 15 76 95 38
Second transmission at 12:26 UTC:
MDZhB 94864 Tritil 6098 1359
Haven’t been able to source the audio recordings in order to confirm these. If anyone has recordings please let me know, or upload them to Soundcloud.
Thu, 16 Sep 2010 17:06:46 +0000
There have been two interruptions to the buzzer today, during which voice transmissions were made.
The first transmission occurred around 13.24 GMT. Further details and audio recording coming soon.
MDZhB 21 157 SPIThNEJ 00 20 5 5 5 3
The second transmission occurred at 15.39 GMT. A male voice read out the following message (all letters spelled out in names):
MDZhB MDZhB 85 343 KRINUM 01 48 04 95 PRIORITYT 14 08 28 71
I wonder what the ‘priority’ is.
Buzzer is still going.

For the enjoyment of everyone who has had the strange pleasure of following UVB-76, I’ve created this experimental track which puts together most of the interesting recent events from the station. Enjoy!
Digg it, Tweet it, hate it, I dunno… just do something! ;)

UVB-76 is buzzing again. Strong signal too.
Sun, 12 Sep 2010 23:37:44 +0000
Not much to report on today apart from another male voice transmission. The buzzer is still missing.
Micha… MDZhB 13 626 TRJHLJTOK 2 0 0 45 29 47 …. MDZhB 13 626 TRJHLJTOK 0 0 45 29 47
Note: all letters are spelled out phonetically, eg. Michail, Dimitry, Zhenya, Boris, etc.
Sun, 12 Sep 2010 11:53:21 +0000
Latest transmission yesterday from a female voice (believed to be genuine UVB-76):
Mihhail Dimitry Zhenja Boris 80 0 30 3 Pavel Roman Jelena Pavel Roman Jelena Konstantin Anna 73 82 67 63
Towards the end it is possible to hear another voice talking in the background. Whether this is from the same transmission is unknown.
Other interesting transmissions, include voices that appear to be answering a phone, now leading to the speculation that UVB-76 is in some way connected to a telephone exchange. Possible if it’s a communications centre. More info on this theory in this post.
There was one other male voice transmission recently, but this is believed to be from pirates.
Fri, 10 Sep 2010 12:18:27 +0000
Feel free to drop by the live chat to discuss UVB-76. Not much happening at the moment as everyone is waiting for the buzz to return. The updates on this page contain all the info that is currently available.
Fri, 10 Sep 2010 08:51:29 +0000
The buzzer has stopped again since yesterday.
Wed, 08 Sep 2010 17:35:56 +0000
After the better part of another day with no activity – there’s been plenty. First a weak buzzer returned, shortly followed by the appearance of a strong carrier signal. After that it seems like they turned on the power because both the buzzer and subsequent voice transmissions have been extremely loud and clear.
The buzzer stopped briefly twice. Once for a male voice doing a test run of counting, and the second time for a female voice making a full voice transmission. The transmission transcodes to:
82 366 prutjnoi 63 85 99 71
This transmission did not use the callsign UVB-76, but instead “MDZhB” (Rus. МДЖБ), although the transmission was very clearly on 4.625 kHz. The transmissions appear to be genuine from UVB-76/MDZhB.
As of this post the buzzer is still on, so listen live.
Tue, 07 Sep 2010 22:37:06 +0000
Apart from one unverified audio transmission, there has been little-to-no activity today.
Still no buzzer.

Some interesting activity over the past few days, some legitimate, some not. Firstly, the UVB-76 temporary internet repeater kit has been upgraded, and it’s now possible to watch a live stream of the WinradHD screen (shows a visual waterfall output of the frequency). Someone is now also recording both the AM and USB feeds into a publicly-accessible archive. Worth checking out if you want a recording of something you heard.
In other news: It appears some pirates have been trying to broadcast over UVB-76’s frequency, and managed to make a message (“XYN”) appear in the waterfall view of the stream (screenshot below – click to enlarge):
Apparently those three letters mean “dick” in Russian. Admittedly this is a cool prank to pull off, however it does detract from everyone’s efforts of following UVB-76. There has also been some “counting” transmissions which were broadcast on UVB-76’s frequency, but may not be genuine.
Aside from that, The Buzzer has been silent. Laid (who runs the live stream) has found a new sine wave being transmitted right next to UVB-76’s frequency. There is currently speculation as to whether this may be related to The Buzzer in some way; possibly as an upgrade/replacement? Follow that discussion here.
As of this post there is still no buzzer.
Sun, 05 Sep 2010 20:58:12 +0000
Will post a full update of activities tomorrow. Stay tuned!
Fri, 03 Sep 2010 00:29:50 +0000
Just heard some more counting. But apart from that UVB-76 is silent again (no buzzer).
Thu, 02 Sep 2010 22:05:37 +0000
Plenty of activity this afternoon. The first piece of interest was a male voice in the background heard saying something along the lines of “these should work, but are very weak” (audio below).
UVB-76 then came back on air and continued the seemingly maintenance-related loop of buzzer-music-buzzer (same as yesterday).
This was interwoven with very clear morse (whether this is directly on UVB-76’s frequency is to be confirmed), and new voice transmissions of at least three people (two male, one female), counting from 1 to 10. Sound clips below.
The third one is most interesting as it’s very clear and contains buzzer, music, morse and counting.
As of this update, we’re still hearing the occasional loop of buzzer-music-buzzer. Just heard one more very distorted male voice counting.
Thu, 02 Sep 2010 09:51:08 +0000
Confirmed the morse code from yesterday was not actually on 4.625 MHz (UVB-76’s frequency), but on a neighbouring frequency used by Russian Navy.
UVB-76 itself is currently silent.
Thu, 02 Sep 2010 01:56:19 +0000
Summary of 1 September 2010:
- UVB-76 carrier (buzzing) went off the air
- A repeating morse code signal appeared (60 second loop)
- Another deeper morse code could briefly be heard
- UVB-76 buzzer returns together with a loop of swan lake music (extract below)
- UVB-76 carrier went off the air again
- Currently broadcasting more morse code on loop (no buzzer)
Current belief is that the station is undergoing maintenance.
This may seem like a deviation from the normal topics I cover, but I’ve been quite intruigued by the recent news of an unusual broadcast from the Russian military UVB-76 numbers station. Numbers stations are radio broadcasts that transmit morse code, or computer-generated voices reading out a series of numbers or words. Their purpose is generally unknown but thought to be used to broadcast orders to military or spies. One rumor suggests it is involved in Russia’s Dead Hand (aka. Perimeter).
UVB-76, located in Povarovo, Russia (northwest of Moscow), is a shortwave radio transmission (4625 kHz – AM suppressed lower sideband) that has been transmitting short monotonous buzz tones since 1982. Voice messages from UVB-76 – also known as “The Buzzer” – have only occurred three confirmed times in the past 20 years, the last known instance being the 23rd of August 2010 (recording below). During this broadcast the buzz tones stopped, and were replaced by the Russian-language broadcast which translates to:
UVB-76, UVB-76 — 93 882 naimina 74 14 35 74 — 9 3 8 8 2 nikolai, anna, ivan, michail, ivan, nikolai, anna, 7, 4, 1, 4, 3, 5, 7, 4
Some believe the transmission referred to the coordinates 74.14N 35.74E, located in the Barents Sea off the coast of Norway and Russia, where Russia is planning on testing anti-aircraft missile systems.
There is also belief that the installation is simply used for ionosphere research, as a Russian science journal indicated research being performed on the same frequency. Although this wouldn’t explain the cryptic messages.
Anyone have any other ideas? Conspiracy theories? In all likelihood, it may be nothing propulsed into the mainstream. It wouldn’t be the first time.
