Suddenly the piercing buzzing noise that has continued incessantly for months stops. A cold voice takes over.
‘U-V-B-7-6’ is read out in a thick Russian accent, before listing a series of code words and numbers. Then, just as suddenly, it ends. The buzzing returns, for another few months.
That is what has greeted listeners of a mysterious radio station nicknamed 'The Buzzer' - and code named UVB-76, or more recently MDZhB - since the 1970s.
But what the Buzzer is doing, or who is broadcasting it, remains a mystery - with theories ranging from the Russian military to atmospheric research.
A Russian radio station has played a buzzing sound on frequency 4625 kHz (shown) for four decades. Every few months it is interrupted by a voice relaying a coded message. But no one knows the exact purpose of the station or the message. Some say it is a military station, or a counter-attack measure for nuclear war
Although its noise has changed slightly over the preceding 40 years, it has always involved some form of regular buzzing, interrupted by a voice on rare occasions seemingly reading out a message.
Today, 25 times every minute, it spends less than a second buzzing, pauses, then buzzes again - endlessly.
WHAT IS 'THE BUZZER'?
Most believe the Buzzer is a Russian military station. Exactly what it is transmitting, though, is a bit of a mystery.
It may be that the station is transmitting data to spies and military groups around the world. The type of shortwave transmission used is well suited for this.
Others, however, believe it is instead, or also, used for scientific research. A recent paper suggested the frequency was being used to bounce signals off the ionosphere.
Delving into the more unlikely, it has been speculated the station may be a ‘Dead Man’s Switch’ system. In the case of a nuclear attack against Russia, UVB-76 would launch an automated counter-strike.
Some have even suggested the whole thing may just be misdirection, as while people focus their attention on decoding the mystery of UVB-76, important communications may be carried out in another manner.
The noise rings out on a frequency of 4625 kHz, which anyone is able to listen in on, including online at one of several live streams.
For years the transmission seemed to originate from the town of Povarovo near Moscow but, in September 2010, the location changed. Now, it is believed to be in Western Russia.
According to the website Numbers Station, the Buzzer ‘works as a communications center within the Western Military District that sends messages to corresponding military units and their outposts.’
The Buzzer has spawned many websites and blogs like this, with amateur radio enthusiasts the world over becoming intrigued by its unsolved mystery.
