UVB-76 The Buzzer Livestream

"The Buzzer", known among Russian listeners as "Жужжалка" (Zhuzhzhalka; English: Hummer), is a Russian military commandment network serving the Western Military District. It broadcasts around the clock on 4625 kHz.

While no other traffic is being sent, the station emits its signature channel marker. The traffic consists mainly of the following standardized types of messages:

"Monolith" type messages
"Uzor" type messages
Command messages
The traffic sent on this station is simultaneously transmitted in Morse code on multiple other frequencies. Channel separation issues have occasionally allowed the Morse code simulcasts to be heard on the voice station.

The Buzzer is controlled from the Sudak communication hub ("Agalatovo"). It has a number of transmitter sites, which are switched between often; some of the identified ones include the 69th Communication Hub ("Iskra") and the 60th Communication Hub ("Irtysh"). The structure is built using old equipment that is prone to failure, and suffers from channel separation issues.
