"The Buzzer" is a common nickname for a Russian Western Military
District commandment network, which operates on the frequency 4625
kHz around the clock. The name comes from its signature channel
marker used to keep the frequency clear - 1.85 s buzzing tone,
followed by a 1.25 s pause.
The source of its transmissions is the Communication Hub #60 of
the staff of the Western Military District, known by its callsign
of their HQ antennas). Messages are sent out in a format known
"Monolyth", using a circular callsign "MDZhB", assigned to the
military units in the Western Military District. There also are
special command messages, for example КОМАНДА 145 (Command 145). It
has been found that Command 145 means training alert (while Command
45 means real alert). By this command all personnel should arrive
into assigned positions.
Because of the large area to be covered, The Buzzer uses at least two transmitters and
the emission varies by the transmitter, and even within the same
transmitter due to their instability. It is possible that
there is a third transmitter that is responsible for transmitting
the carrier while the other two alternate on transmitting the
One of the transmission sites is located near Saint Petersburg,
which belongs to the 60th Communication Hub located on Palace Square in St.
Petersburg. There is a document circulating on the Internet,
related to the site renovation project, which has provided us with
the site antenna
field schema. The second buzzer transmitter site is
believed to be located near
Moscow, which belongs to the 69th Communication Hub.
The Buzzer was first reported as early as 1976, and as late as
1982. Prior to 1990, its channel marker was a short, high pitched
tone emitted every two seconds. In September 2010, its activity
has significantly increased, due to much larger area to be covered
(new Western Military District; The Buzzer formerly served the
Moscow Military District) - some facts and faces about The Buzzer

Can be heard in the UK on 4625khz after dark, buzzing
relentlessly. Just before the top of every hour, the signal
changes, as in this example. The Buzzer has been on the air since
at least 1987. The station is not I.T.U. registered, and has no
callsign. See Enigma Newsletter number 11.
