Strange codes
Evolution of the call signs
It is believed that the early messages (of which no recordings exist) were misheard and transcribed
as UVB-76 (УВБ-76) while the correct call sign is UZB-76 (УЗБ-76). The UZB-76 has been
verified to be correct by native russian speakers on instances where recordings exist. Call sign
UZB-76 fell into disuse after September 10, 2010 when one message was sent. A new call sign
MDZhB (МДЖБ) came up on the 7th of September and 4 messages were sent before the farewell
message with the call sign UZB-76.
Only MDZhB was active the rest of 2010 and up to February 14, 2011 when new call signs KZJT
LNR4 (КЗЙТ ЛНР4) were used in one message. Another message with two call signs was heard on
24th of February with the first call sign being used only 10 days earlier, KZJT MBYShch (КЗЙТ
МБЫЩ). Further 7 new call signs were heard between March and October of 2011, all with 1-3
messages before disappearing. Rest of the year and up to mid-March of 2012 was dominated by
MDZhB call sign.
On March 13, 2012 a total of 18 messages were sent. A call sign OYeUN (ОЕУН) from August
2011 made a return with one message and three new call signs 'B2M HN87 (ЬБ2М ХН87) and
2BYP (2БЫП) sent one message each. The 'B2M HN87 – 2BYP messages were especially
noteworthy since it was the second ever observed instance where the ID group numbers match.
Another first on that day was a MDZhB message with two ID groups, a feature that has previously
been reserved for “rare” call signs only.Call sign types and message structure
Messages sent by Buzzer can vary in their formatting but can be classified under few different
subtypes. Below are diagrams to illustrate the types. Complete text including call sign repeats are
shown, all letters are pronounced phonetically. Messages are repeated once with identical content.
With one exception all messages so far consist of one or two call signs followed by one or more
number sets of varying length and finally a group or groups consisting of a code word and four 2-
number sets. The exceptional message contains 5 call signs and is classified as type 4-3.
Please refer to appendix A for transmission types in a table format.

Type 3
Messages addressed to two call signs, very rare.
It is very likely that these are two separate call signs and not a single one consisting of two words
because the call signs are read and repeated separately, for example “ЬБ2М ЬБ2М ХН87 ХН87”.
Other Russian military stations which use 2-word call signs announce them by reading the whole
call sign before repeating it, for example in the case of the Squeaky Wheel the callup is read as
“Альфа 45 Альфа 45”.
Furthermore the call sign KZJT (КЗЙТ) has been used in conjunction with two other call signs in
two different messages. Also, the call sign OYeUN (ОЕУН) has appeared both as the sole recipient
of a message and in a double call sign message with the most active call sign MDZhB (МДЖБ).
Two distinct types of messages emerge when examining the type 3 transmissions. Messages where
the second call sign is read only once always contain a 2fg 2fg irregular ID group, while messages
where both call signs are repeated twice do not contain this group.
In common radio tradecraft the call signs are usually repeated twice and the lack of this repetition
does not look like an accident. The whole message is repeated after the first reading and in this the
call sign is also only read once. Also the additional 2fg 2fg irregular ID group is seen in these
messages and yet it is absent in the messages where both call signs get repeated twice, making a
strong case that the reading is done like this in purpose and there is something in the message
design that dictates this action.
Taking this assumption, the second call sign can't be the intended recipient but would turn into part
of the message itself, so station MDZhB would receive a message regarding station OYeUN with
extra instructions of “47 05”, followed by a regular message format with an ID group and message
group. The latter message type where both call signs are read twice contain two regular ID groups and a
reasonable assumption can be made that the same message is intended for both recipients but
unique ID groups might be given for each of the stations.Type 3-2-1-1-1-1, two call signs, first repeated twice, second repeated once, one irregular ID
group, one regular ID group, one message group

Messages with call signs other than UZB-76 or MDZhB
Only a handful of messages with call signs other then UZB-76 or MDZhB have been sent during
the known history of the station. Why other call signs are sometimes used is debated, but one
plausible possibility is that the call signs address the recipient, not the station identifying itself.
Messages that contain two call signs are especially problematic to explain away if it is thought to be
the transmitting station call sign.
Call signs assigned to a unit, area or function are not uncommon in military communications and
this would explain why the overwhelming majority of messages are addressed to MDZhB, the
Buzzer being the local communications link to it with only occasional needs to contact anyone else.
This might also explain why the old call sign UZB-76, active at least since 1997 was phased out in
September 2010, shortly after the Buzzer changed it's transmitter location.

conjunction with OYeUN, rare call sign rightly belonging to this list.
Duplicated messages
One common feature with Buzzer messages are a high rate of duplicates, repeated up to 4 times,
sometimes years later.
Typically the code word and related 4 number groups are repeated, not the ID itself. In some cases
message with only one code word is later repeated in another message that has two code words.
Repeats also span multiple call signs so basically every possible permutation has occurred.
Examples of different types of duplicates
Split repeat, 2-group message sent in January repeated in two separate transmissions in May.

MDZhB call sign.
On March 13, 2012 a total of 18 messages were sent. A call sign OYeUN (ОЕУН) from August
2011 made a return with one message and three new call signs 'B2M HN87 (ЬБ2М ХН87) and
2BYP (2БЫП) sent one message each. The 'B2M HN87 – 2BYP messages were especially

Type 3
Messages addressed to two call signs, very rare.
It is very likely that these are two separate call signs and not a single one consisting of two words
because the call signs are read and repeated separately, for example “ЬБ2М ЬБ2М ХН87 ХН87”.
Other Russian military stations which use 2-word call signs announce them by reading the whole
call sign before repeating it, for example in the case of the Squeaky Wheel the callup is read as
“Альфа 45 Альфа 45”.
Furthermore the call sign KZJT (КЗЙТ) has been used in conjunction with two other call signs in
two different messages. Also, the call sign OYeUN (ОЕУН) has appeared both as the sole recipient
of a message and in a double call sign message with the most active call sign MDZhB (МДЖБ).
Two distinct types of messages emerge when examining the type 3 transmissions. Messages where
the second call sign is read only once always contain a 2fg 2fg irregular ID group, while messages
where both call signs are repeated twice do not contain this group.
In common radio tradecraft the call signs are usually repeated twice and the lack of this repetition
does not look like an accident. The whole message is repeated after the first reading and in this the
call sign is also only read once. Also the additional 2fg 2fg irregular ID group is seen in these
messages and yet it is absent in the messages where both call signs get repeated twice, making a
strong case that the reading is done like this in purpose and there is something in the message
design that dictates this action.
Taking this assumption, the second call sign can't be the intended recipient but would turn into part
of the message itself, so station MDZhB would receive a message regarding station OYeUN with
extra instructions of “47 05”, followed by a regular message format with an ID group and message
group. The latter message type where both call signs are read twice contain two regular ID groups and a
reasonable assumption can be made that the same message is intended for both recipients but
unique ID groups might be given for each of the stations.Type 3-2-1-1-1-1, two call signs, first repeated twice, second repeated once, one irregular ID
group, one regular ID group, one message group

Messages with call signs other than UZB-76 or MDZhB
Only a handful of messages with call signs other then UZB-76 or MDZhB have been sent during
the known history of the station. Why other call signs are sometimes used is debated, but one
plausible possibility is that the call signs address the recipient, not the station identifying itself.
Messages that contain two call signs are especially problematic to explain away if it is thought to be
the transmitting station call sign.
Call signs assigned to a unit, area or function are not uncommon in military communications and
this would explain why the overwhelming majority of messages are addressed to MDZhB, the
Buzzer being the local communications link to it with only occasional needs to contact anyone else.
This might also explain why the old call sign UZB-76, active at least since 1997 was phased out in
September 2010, shortly after the Buzzer changed it's transmitter location.

First line in latin, second in cyrillic.
March 13, 2012 was the exception to this list with call sign MDZhB used, however used in
conjunction with OYeUN, rare call sign rightly belonging to this list.
Duplicated messages
One common feature with Buzzer messages are a high rate of duplicates, repeated up to 4 times,
sometimes years later.
Typically the code word and related 4 number groups are repeated, not the ID itself. In some cases
message with only one code word is later repeated in another message that has two code words.
Repeats also span multiple call signs so basically every possible permutation has occurred.
Examples of different types of duplicates
Split repeat, 2-group message sent in January repeated in two separate transmissions in May.
