M42 & X06: the story so far..........

The Russians have quite a lot of stations that transmit coded messages on LF/MF/HF. Like all other numbers station it's hard, if not impossible, to find out if the transmissions are actually related to espionage activities. Some most probably are spy stations, some are definitely linked to governmental communications (embassy traffic etc), but I guess that the majority of the stations are military stations, either GRU related or just plain military activity (tactical nets, naval stations, etc). Most of the military stations don't have a specific Enigma code but can be cataloged under former Enigma code M32. Let's start with the list of Enigma designators for these stations. Note that Enigma deleted a number of these designators, but for clarity we will still be using them here.

The RTTY/digital network has been monitored by a large number of dxers since the early 1980's and even before that when they were using Morse only. When we first discovered the network we didn't know who they were, so we nicknamed them "the Brotherhood". A couple of years and a lot of work later we knew that this is in fact a Soviet, now Russian, governmental network.

In the 1990's a new name was used by the dxers. According to several sources the main user of the net was SOUD, so this name replaced "the Brotherhood". Later FAPSI has been used. FAPSI is responsible for maintaining both government and presidential information system and telecommunication lines. It controls Russia's physical communications systems, including government telephone lines, high-frequency communications, and cryptography services. FAPSI initially maintained communications lines for the Russian President and security services. Basically they were and still are responsible for the actual transmissions. One of the other names that was used after FAPSI is DOSC, Department of State Communications, a name that is more appropriate then the ones used before that. To simplify it even more we now use "Russian Government/Intelligence" or just "Russian Gov.".

The first encounters in the USA with the "Brotherhood" stations were in the late 1970's when they still used high speed CW (ca 32 WPM). Most of the early CW stations (PSN, BPA, SPK, WNY, YBU) were still active in the late 1990's. "ROL" however disappeared completely. In the mid 1980's the RTTY transmissions started. The speed used was 50bd. Messages to YBU were the most common ones in those days. Also messages to PSN were monitored. The callup was slightly different from the system that is used nowadays:

VVV PSN PSN PSN 2/245 VVV PSN PSN 2/245
NW NW
NR 271 GR 135

+ 5L or 5F groups

Then in the mid 1980's they changed to the 5 group preamble that they are still using today. But the original link designators were different back then.

The WFO/MIG link was the only known 2-way link in the Americas. The station sending WFO was definitely the Cuban end. The other end has been pin pointed in the New York City area, probably the Russian UN delegacy.

In the late 1980's an European network of RTTY stations popped up, similar to the network that was active in the America's.

The master station in Europe was "RCF". Several frequency guides listed "RCF" as Ministry for Foreign Affairs in Moscow. After the disintegration of the USSR, the "RCF" callsign disappeared. The new master station was as powerful as "RCF" was and one thing is for sure: this station was located in or very near Moscow as well. The station was DFed many times and every time Moscow appeared to be the source of the signal. Whether the master station or "RCF" really was MFA Moscow is not 100% sure but it definitely was a diplo station and the net a diplo network. Whenever something hot was happening in the 1990's, like the Chechenya actions, the stations in this net were making overtime, even on Sundays, while there were normally no transmissions on Sundays. The only station that was often heard on Sundays was "BFR", which may indicate that it was possibly located in an Islamic country.

The master station still transmits online and offline encrypted messages to the other stations. There are fixed schedules for a couple of stations while others are reported less frequently. During the time that "RCF" was still in place they used a traffic list system. In the 1990's the traffic list system was replaced and each link now had one or two fixed schedules on an assigned frequency pair. The auto-broadcasts to amongst others KUL, VKX, RAU and RKD were probably just circulars or routine traffic sent to the specific networks. They were transmitted blind and therefore repeated throughout the day on a larger number of frequencies.

RTTY was the major system. The callups and messages can be divided into two groups: the most common one for the America's and Europe was: "4646464646464646 KUL KUL KUL KUL 1/226". Note that 46's are transmitted instead of RY's, then the callsign of the recipient and the number of messages/number of 5-letter or 5-figure groups in this message. The other one was only noted in Europe but might have been expanded by now. The transmissions start with a selcal of 6-tones (the selcal system is called Mazielka), followed by the callsign of the recipient sent in CW, then into RTTY where the preamble is handkeyed while the other system had an automated preamble. The Mazielka callup has been reported since mid 1994. The Mazielka is a selcal system that was used by the master station to wake up a station outside the normal fixed sked. It was probably only used to catch the operators attention, not to start the equipment remotely. The fact that they switched to CW after the Mazielka was a sure sign that the operator had to prepare the equipment before they could start the transmission. The use of non-error correcting RTTY systems made it practically impossible to establish a link automatically. The Mazielka was never used during the normal schedule times. Nowadays the system seems to have a more structured behavior and the system may even automatically switch on the receiving equipment because they hardly start with CW anymore. The CW operator chats that follow the messages are still there though.

We have found several clues about the preambles and QSL's of the link system that is still being used, although less frequent than in the 1990's. Let's take a closer look at the preambles. Each message starts with a preamble that consists of 5 groups, followed by the message itself. A typical preamble looks like this: 11177 00142 23687 05012 01109.

After the messages have been sent, the operators sometimes have a little chat. In the America's the conversations were in often poor English while on the European side they often chatted in Cyrillic.

As I mentioned earlier, they also used QSL messages. The original messages were transmitted on other frequencies and even on other days then the day the QSL messages were sent. Note the first group of the preamble is always 11199 and the messages always started with 55555 followed by 77011, while the last groups represent the QSLed messages. A typical QSL preamble and message looks like this:

11199 00142 00000 18010 00069
55555 77011 00089 00090 00091

Various RTTY speeds were used on this net in the 1990's. The most common were Baudot 50Bd, 75Bd and 100Bd with 500Hz shift. Besides RTTY also CROWD36 and Morse have been used.

In the (recent) past many Direction Finding activities were conducted with good results. The European master station is located in the Moscow region, while the now defunct WFO/MIG link was the link between Cuba and the New York area, probably the Russian UN legation. Station GMN could have been located in or near Mexico City. Most transmissions came from either Moscow or Cuba. Only a few other locations are known. See further the callsign list at the end of this article.

Moscow sends messages to many other stations, most likely governmental stations like embassies and consulates. The transmissions from Cuba were to BAR, BPA, HZW, JMS, KAC, NDO, PSN, SPK, WFO, WNY, YBU; all unid locations except for WFO.

There is a very significant feature to the 5-letter traffic. The last group of every message is a simple substitution which indicates the date the message was composed and the group count which is always 3 less than the group count shown in the preamble. The substitution is:

O I U Z T R E W A P
0 1 2 3 4 5 6 7 8 9

For example:

11177 00148 57477 26811 00609

5LGs QKANG XOBJZ ..................... VEVXX UEORW

The last group translates to 26057 -- 26th of the month, 57 groups.

Message samples

A very popular one in the 1990's was the master station in Moscow that sent blind routine messages to KUL, VKX and several others at a fixed daily schedule. Note the "46" test slip instead of "RY". "KUL" is the callsign of the recipient, there are 3 messages with a total of 535 5-letter groups. (messages shortened)

Analysis shows that starting at the third group, this message uses a trinomial (3-digit) code. When sent as 5F groups, the first two digits of each 5F group are nulls. All of the code groups begin with either a 6 or a 7 except for the one group (repeated three times in the message) which uses 44 as the nulls.

Nowadays, in 2009, some of the old preambles and message formats are still being used:


With the introduction of new systems the formats changed. There are quite a few different formats now. I am not sure if each type is linked to a specific user (i.e. diplo, military, intelligence). Messages nowadays consist of 5LGs, 5FGs, 17FGs, 18FGs or 20FGs.

On CROWD36 channels headers like these are quite common:

Other formats on non CROWD36 channels.

Modes

The governmental transmissions that we monitor are a mixture of intelligence, diplomatic and military stations. During the past 10 years a host of digital modes have been used by the Russians. In the past most of the transmissions were in AM, USB, CW and RTTY. The first CROWD36 logs are from late 1999 and after that all the modes that are mentioned hereafter were introduced.

We still can listen to voice and morse numbers stations but the majority of the other transmissions are in modern digital modes, heavily encrypted. The Enigma designator for the majority of the digital stations was M42. Enigma 2000 deleted this designator but N&O will still be using it. The polytone stations however are not catalogued under M42 but under XP and the Mazielka has X06 as designator.

M42 / X06 have been using a lot of frequencies during the past 10 years. This list is most definitely not complete. The mazielka calls are sometimes heard on the same frequencies as M42.

I'd like to thank all the people who have been monitoring these stations during the past decades, especially the former WUN members and members of the UDXF, Spooks, ENIGMA 2000, and anonymous dxers who were so kind to share their logs with us.
