<p><font face="Verdana">A regular signal with a rough rasping modulated tone
heard on 4625 kHz, "The Buzzer" is believed to have been transmitting
since the early '80's. </font></p>
<p><font face="Verdana">During 1994 transmissions of the 4625 kHz signal
were heard for several hours simulcast on 5310 kHz (June 21 1994), and
from 1200hrs to 1800hrs UTC on 5211 kHz (Sept. 1994). This may have been
while testing and setting-up was taking place.</font></p>
<p><font face="Verdana">This signal transmits around the clock, although due
to propagation is usually only heard during the late afternoons and hours
of darkness in the UK. Sounds a bit like a time signal, but sends
around 25 pulses per minute. At 1 minute to the hour, the signal
changes to a continuous tone rising and falling. </font></p>
<p><font face="Verdana">Accuracy is variable and the station has been heard
sending the "hour" tones up to 3 minutes either way. </font></p><a href="http://www.brogers.dsl.pipex.com/buzzer.mp3" target="_blank"><font face="Verdana"><img src="http://www.brogers.dsl.pipex.com/sp-logo.gif" border="0"> <font color="#3300ff"><b> "The Buzzer" (50
kb)</b></font></font></a><font face="Verdana"> </font>
<p></p>
<p><font face="Verdana">On January 16 2003 the tone used by the station
changed to a higher pitched tone with a slightly longer duration, giving
around 20 pulses per minute, although the signal has now reverted back to
the original tone and duration.</font></p>
<p><font face="Verdana">"The Buzzer" also sends messages periodically, which
are usually around Christmas. On 25 December 1997, at 2158 UTC, the tone
ceased and a message was read out in Russian. </font></p>
<p><font face="Verdana">In personal E-Mail, Rimantas Pleikys in Lithuania
has provided me with a full translation of the message.</font></p>
<p><font face="Verdana"><b>"This is UVB-76 18008 BROMAL
74279914"</b> (Repeated several times).</font></p>
<p><font face="Verdana"><b>UVB-76</b> is believed to be the callsign of the
station which would indicate a Ukranian source under the international
agreement on callsign allocation, however the station has been reliably
tracked to Russia. </font></p>
<p><font face="Verdana">Rimantas adds that the word <b>BROMAL</b>, which was
spelt out phonetically, has the same international meaning - that being a
chemical. This would seem to be a randomly selected Codeword.</font></p>
<p><font face="Verdana">Similar messages have been intercepted by monitors
at various times. It is believed that the frequency is monitored at one or
more sites on a permanent basis, and that the receiving stations, on
hearing one of the messages must immediately contact "control" and repeat
the message and codeword to show that they are alert and
monitoring.</font></p>
<p><font face="Verdana">It is believed the station is military in origin
possibly connected with the Strategic Rocket Forces who control the
nuclear ICBM missiles. Jan Michalski on his webpage, (see below), states
that the station is part of the Central Communications Hub of the General
Staff of the Army, and serves the same purpose as the US EAM
messages.</font></p>

<p><font face="Verdana">The transmitter site is in woodland near Povarovo,
in Western Russia, about 50 Km NW of Moscow, and in 2004/5 was tracked and
photographed by a group of Russian lads who were kind enough to email me
the photographs which are on displayed on this page. </font></p>
<p><font face="Verdana">Lower power back-up transmitters are thought to
exist (though these may be at an alternative site), as simulcast
transmissions of the "Buzzer" have been heard on 3842 kHz & 3877 kHz
at different times in parallel with the 4625 kHz transmission.</font></p>
<p><font face="Verdana">A rare report of "The Buzzer" from a Pennsylvania,
USA member of ENIGMA 2000, in March 2004, reported the signal as "Weak but
audible in AM mode".</font></p>
<p><font face="Verdana">Sincere thanks to Rimantas Pleikys for his help and
for making his findings available to me, and to the Russian "Urban
Explorers" who visited the site.</font></p>
