<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>

color="#3300ff"><b> "The Buzzer" (50 kb)</b></font></font></a><font
face="Verdana"> </font>
<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 align="center"><font face="Verdana"><br>
</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>

station, visit Jan Michalski's page </font><a moz-do-not-send="true"
