CIS Navy on HF
« on: May 31, 2019, 1727 UTC »
                 Overview of Russian Federation Naval HF Comms

                                The Russian Navy
                            "The Crew—One Family"

                VMF - Voyenno Morskoy Flot Rossiyskoy Federatsii
                     Military Marine Fleet Russian Federation
                              ==================

 Surface Ships of the CIS Navy employ cw "41st Channel" via hf radio networks "Globus" (globe), "Equator" (self explanatory) or "Vympel" (Pennant)

Globe seems to be the top echelon command network while Equator may mean hemispherical comms regions, Vympel (Pennant) may mean comms between units under a specific flag/fleet command and their subordinates

For example;
 KRASNAYA OKTOBER (a very sneaky ficticious ruskii submarine) transmits to Murmansk RIT over the Vympel network, RIT then passes the traffic to Moscow RIW via the Globus network.

 Submarines of the CIS Navy employ superfast telegraph (SAD = Russian acronym for high speed cw?) via radio mode "Akula-Splav" (Akula = shark, Splav = Alloy) or "49th Channel" via hf radio networks "Globus" (Globe) or "Okean" (Ocean). "49th Channel" may be Akula mode specific rather than routing all digital mode traffic. To be precise, Akula isn't CW, it's phase coherent FSK and PSK in Akula II. Subs aren't the only units to deploy Akula.

Often, CW traffic passage is preceded by tuning procedures composed of a series of Vs and/or random dits and dashes.
All stations that are going to be heard in this net period will be tuning their systems to the net freq.
Radio checks take place after every day/night frequency change; 1800Z & 0600Z.
Sessions are closed with "ZNN ZNN sk sk" by the NCS.
As a general rule, expect QTC traffic on the hour, synoptic traffic at 0000/0300/0600 etc you get the idea
For example, right now 2222Z 13DEC19 there's the faintest of very fast CW on 12464, my guess 30wpm or better and way outta my league.


The terms "CIS Navy" (Commonwealth of Independant States Navy) and "RN" (Russian Navy) are used interchangeably.


                               The Easy Ones

 CIS Navy CW qrgs
Fleetwide primary freqs
08345 (1800Z to 0600Z)
12464 (0600Z to 1800Z).
However there are many regional frequencies that are used, and are being more used than primaries these days
The 0600/1800 QSY is apparently a suggestion not a maxim so one can find traffic on either freq regardless of the current Moscow Time; 3 hours ahead of UTC

8348 is a primary Pacific fleet frequency which may propagate to the US, also try:
3594
4048
4190
5233
5411
5142
6240
6242
6989
7630
7632
9142
10203
10834
10834
13636
13907
18373

If you're located in the midwestern US you'd logically try to hear traffic to Navy HQ St. Petersburg RAA on 8120 evenings/nights, and perhaps traffic to Navy HQ Moscow RIW on 8345 (after 1800Z) or 12464 (after 0600Z) as these HQ are geographically closer to the monitoring station than say Murmansk (artic circle) RIT 5343, 7467, 11155 or especially Vladivostok (pacific coast of Russia) RJS on 4048, 5411, 7632, 10203, 13636, if you lived on the west coast US you'd logically try for the opposite as Vladivostok is much closer and only a salty okean (ocean) away from you.

This will become even more apparent and important as the sunspot numbers keep dropping and propagation fails to deliver. Fortunately we have remote sdrs we can log into to get our itch scratched. Who coulda thunk in 1989 that today, from any place in the world that has innernet connection, one could freely log onto an sdr located in Moscow and tune the hf spectrum at will, perhaps mere blocks from Kreml.

Duplex Circuits;
Many RN CW nets in use are duplex, ship transmits on one freq, shore transmits on another.
RIW Moscow sends to ships on 9145, 11000, 14556
RCV Sevastopol sends to ships on 15586 day and 7566 night, with weather reports also on 5915, in the past on 10543
So when you hear traffic on 7345 or 12464 look for the other side on the above freqs, but these are by no means all in use.

 CIS Naval callsign convention and generally follow ITU convention.
Most calls; ship, shore, or air, prefix with R.
Stations are assigned signs from the RAA-RMZ range and RJC ## - RJH ##
There are exceptions to callsigns, for example Magadan, RTS

Aircraft seem to have a random 3/4/5F call after the R regardless of their home base.
Afloat units do not have calls related to their fleet; for example, Northern Fleet units from Murmansk do not prefix their calls with RJD.

RDL is generally believed to be a collective address to "all nuclear strategic forces", in essence RDL = EAM

WLHN is generally believed to be a collective address to all units of the Armed Forces

Submarine units don't have known given calls ota on hf, as subs mostly use laser/satcomm buoys with, presumably, Akula as backup. That being said, Akula is also used for recon/int work by afloat units (AGI) so not every Akula sig's going to be a sub.

 Much traffic generated on CIS naval nets is comprised of position and local weather reporting, they seem to follow the reporting guidelines in this publication;
https://www.jcs.mil/Portals/36/Documents/Doctrine/pubs/jp3_59.pdf

 CIS NAVY Meteo Callsigns
RJE73 = BLACK SEA FLOT METEO
RJH45 = MOSCOW NAVAL METEO
RJH74 = NORTHERN FLEET METEO
RJD38 = BALTIC FLOT METEO
RJE65 = BLACK SEA FLOT HQ, NOVOROSSIYSK

 Hydrographic messages are normally sent every six hours – 0600z, 1200z, 1800z and 0000z.

With the above in mind, radio hobbyists can track certain CIS Naval assets from port to patrol area, AGI and subs excluded.

Ship of electronic reconnaissance project (example 864/B Baltiysk 72DRK)
Russian AGI class of ships (remember the USS Pueblo?) do not send hf cw weather/position reports unlike other afloat units, I presume they have laser/satcoms as well as Akula just like the subs. As most USN task forces grow their own RN AGI tail and there seem to be continuous RN AGI haunting NATO and USN naval bases, their position is known to USN regardless if they send on hf, the NATO/USN radio traffic they intercept is likely sent by laser/satcom to RAA and Moscow. There may be more than one AGI tailing USN forces, or near Cape Kennedy when rocket launches are to take place as missile telemetry is a high priority target for AGI ships of any nation.

 Also while RN forces use Cyrillic morse, they use a lot of Q and Z codes with the same meaning Q and Z codes have in the west.

Afloat units can bypass their respective HQ and contact Moscow directly. This may be due to propagation not favoring HQ or by command. Likewise, afloat and airborne units have freqs they guard that are a hotline from Moscow for flash messages, as well as their HQ freq. It's not uncommon for various HQ or even afloat/airborne units to relay comms from units that aren't organic to that command.

CIS Naval forces have some 600 known HF freqs in use, you can find a list at udxf or elsewhere but units are presumed to be frequency agile and can pop up anywhere.

CIS Naval messaging has a hierarchy like most other military message systems;
MNL “Monolith” Flash (XXX in RN cw)
VZD “Air”         Immediate
RKT “Rocket”    Priority
SML “Aircraft”   Routine


CIS Naval cw is often part of RN digital bcasts for setup and takedown of links, typically BFSK T600 modems, with the cw being created by employing a single tone of the BFSK pair as the cw carrier. I presume the modem traffic from land units is along the lines of the NATO/USN BRASS S4285 and 50/75Bd FSK bcasts.

 Main Russian Naval radio centers / callsigns in Rossii and English

 Globus (Global Network)
RIW / RJE56 / PROGRESS / KOMPASS
Moscow
This station gets input from all other HQ, while lower commands get input from their respective afloat units.
This is the seat of political command.

RAA / RJC66
St. Petersburg National Defence Control Center
Russian Naval C3 center, base component is RJC66
This is Russian Navy HQ. All lower HQ and afloat/airborne units send to this station as SOP but those stations can and do bypass HQ and send direct to Moscow when tasked or when unable to raise HQ or get a relay to HQ. Certain priority traffic (Akula reception, typically meaning a sub or AGI) is simultaneously sent on to RIW via all means available, cw, fsk, land line, etc. Submarine related traffic has highest priority in RN comms.

The Northern Fleet has also been tasked with Arctic Joint Strategic Command. This arctic activity is going to increase greatly in the next decades as Russia is spending billions on revitalising/modernising old bases as well as building new ones. Increases in personnel are likewise taking place as Moscow stakes claim to vast natural resources and the military advantages of an arctic position. We might expect to see more NATO and US activity in this region to counter the perceived threat.

Monitoring Russians afloat was perhaps more interesting and easy back in the days when there was an insane amount of Russian Merchant Marine traffic on hf.
No matter what time of day, you could find some poor faktori/akademik/ryba ship sending messages back home for crew or admin even when the bands were dead. They used cw, but much traffic was in the form of radiogramma, radiograms, sent via BFSK SITOR. If you had a PK232 with the SIAM rom you could copy in 3rd shift Cyrillic if you wanted, I did sometimes but much more often simply used ITA2. In ITA2 mode, Russian words would in many cases almost be translated into something an English speaker could understand, and could follow the message gist. If it was a kryptogrammy being sent, it was 5F groups so don't waste your time.

One always kept in mind that being a totalitarian state, every soviet merchant ship was a military vessel, kinda like how most soviet airliners had jumpseats for paratroopers. "Trawlers" were often festooned with myriad m/h/v/uhf antennae, sure they had to fish, but the kgb/gru crew members ran the elint gear below decks trolling for signals while the rest of the crew cast nets.

This every trawler = a RN AGI mentality pissed off a lot of the five eyes units tasked with monitoring every Russian ship afloat, no matter how small and/or boring its activity.
https://en.wikipedia.org/wiki/Five_Eyes
But NSA had to have the data, knowing that if it rated a trawler it was obviously something the soviets were interested in, thus something NSA was interested in.

Hard to imagine the fortune and lives spent on this crap.

I must admit SITOR worked pretty good for the most part and seemingly links much faster and more reliably than many ARQ modes used even today, but it's not as hardy a mode or as fast as the newer stuff. The Russians liked SITOR so much they devised their own modifications to it beyond 3rd shift Cyrillic and used it when everyone else had gone to other means. Now I suppose a lot of Russian MM traffic is via satphone text and voice.

Who knows, you might someday monitor "The Kuz" (Kiev Class Aircraft Carrier Admiral Kuznetsov), or the "Yuri D" (Borei-class submarine Yury Dolgorukiy)

 RN Naval Digital Modes
----------------------------

 T600

https://www.sigidwiki.com/wiki/CIS-36-50
http://www.wavecom.ch/content/ext/DecoderOnlineHelp/default.htm#!worddocuments/cis3650.htm
T600 (and derivatives, of wich there are several, some in use by other RN forces) is the actual name for the modem, it's also called BEE and 36/50 by hobbyists

While a Baudot decoder will print on T600 sigs, it's not Baudot code so one needs a decoder crafted for T600.
Apparently T600 employs 3:4 encoding for error check, similar to SITOR in that respect. I suppose T600 is the most common RN digital (non cw) mode on hf.

Some of these T600 freqs are up continuously as a kind of channel marker, idling (looks like reversals to a Baudot decoder) until a message arrives, others only send when there is traffic, at H+10, 20, 30, 40 & 50:

Simulcast T600:
1. 10712, 11088, 15778, 16808, 20536, 22413
2. 5890, 9224, 11524, 14581, 16207, 19688, 19936
3. 14192, 16234

RDL cw and T600:
(simulkeyed with 21.1) 8130, 10164 6. 3196, 5846 7. 5178, 8436
(simulkeyed with 18.1) 3363, 3861, 4043, 4446, 4582, 4602, 5268, 5438, 6342, 6962, 7657, 7816, 8488, 8508, 9346, 10452, 10535, 11468, 12098, 12631, 12741, 13032, 14411, 14664, 15768, 15871, 16912, 17460, 18764, 19210, 20096, 22864

The cw traffic is comprised of opchat between the ends of the link using mark or space as the cw carrier, normally taking place before, between, and/or after T600 traffic. This opchat may have interesting tidbits and is sole reason some monitors watch T600 channels.


Commonly heard in US;
14411, 14664, 16206, 16808, 17460

For an up to date list of T600 channels you will want to get the latest logs from udxf.io or similar hobbyist websites.
That being said, one of my goto T600 channels to watch as a prop indicator is 11039.

Rivet is a free to use decoder often used by hobbyists to decode RN Navy digital traffic, and supports these modes;
Baudot (various speeds) : Used by amateurs , weather stations and other users.
CCIR493-4 : A HF selective calling mode
CIS36-50 (50 baud only currently) : Used by the Russian Navy.
CROWD36 : Used for Russian diplomatic and intelligence messages
FSK200/500 : Used for Russian diplomatic and intelligence messages
FSK200/1000 : Used for Russian diplomatic and intelligence messages
FSK (raw) : For advanced users to investigate unknown FSK modes
GW FSK (100 baud) : A commercial ship to shore data system.
XPA (10 and 20 baud) : Believed used for Russian intelligence messages.
XPA2 : Believed used for Russian intelligence messages.

 AKULA

- a signal of national communications "SHARK", used in the Navy. Suffice it to the old system, the transmission is encrypted, of the characteristics, the preamble begins with twice the "plus" in terms of duration, spacing is exactly equal to twice the speed of manipulation, and manipulation without breaking phase.

(Low Range)    ~500-600 Hz, SBB
(Baud Rate)    500 Hz

The above Akula info translated from the RUScanner webpage

Akula = shark in Rossii
The Akula modem is a phase coherent BFSK burst modem used by submarine and surveillance forces of the Russian Navy. I suppose the subs can either deploy a vertical from conning tower, towed buoy, or water jet antenna to send via, but 15kw on hf to a trailing wire antenna a meter or so below surface might do too.

The Akula-II modem is a complex, dual-channel Differential BPSK burst modem.
http://staff.ustc.edu.cn/~jingxi/Lecture%209_10.pdf
"Dolphin" is a minor variation of the Akula radio mode(s)
"Ishmael" and "Dnieper" was similar

Parse ASCII transparent charset and synchronous framing or raw bits to view transport and payload.
Akula ACF; 1356 2594 2713

Traffic has/may consist of 10 five-digit groups, time in the air - 0.72 seconds (in closed mode).
RN Submarines have employed up to 15 kW output power in Akula mode.

Akula messages received by shore stations are instantly relayed to the CIC of the RN on all available communication channels. Akula has also been noted in use by surface "recon" ie surveillance units and might be a method used for transmitting emergency traffic of flash precedence by Akula equipped RN units.

Akula messages are copied via 135 radio reception centers of the Russian navy, keeping in mind submarine-related comms have highest priority in Russian Navy

A short BPSK burst is seen before BFSK Akula traffic commences, I presume this is indication Akula-II hardware is in use. I also presume Akula is based on WW2 German efforts to do the same thing, covertly send messages from submarines to HQ on hf;
https://en.wikipedia.org/wiki/Kurier_system
However the kurier system was more or less just very fast morse, its main benefit in reducing the amount of time a signal was ota, thereby reducing chances of discovery and direction finding. The main problem with short duration hf comms, other than propagation, is a noise burst can take out a portion of or entire short communications burst, not to mention bit smearing from multipath that will likewise also be present to one degree or another.

Buy you an Akula modem!

Speaking of Russian Radio Hardware....

If they sell these things on the open market without changing their freq ranges they just told us where to look for their emergency frequencies.



 AT-3004D

This aging PSK/MFSK/OFDM modem is in use by RN forces and is likely or has been replaced with newer and more capable equipment AT-3104. That being said, it's all over the spectrum in use by Russian Navy for the most part I presume the 3104 is backward compatible with 3004.
Traffic consists of text/data and encrypted voice.
http://priyom.org/military-stations/russia/at-3004d
https://www.sigidwiki.com/wiki/CIS-12

Something to consider is that while elite RN forces, submariners to flyboys, often get the newest and most advanced weaponry and electronics, elements farther back from the point of the spear have to make do with perhaps obsolescent and certainly older equipment, eventually as more advanced gear comes into the TOE (table of equipment) more units will be so equipped.
They've developed some neat gear, they just can't afford to make a lot of it right now.

This technology trickle down theory has always been the case apparently. For example, in the late 50s and early 60s as Akula was being developed and tested in the field, only certain subs got the equipment, no surface units had it until much later, like into the 90s. This likely coincided with the desire for RN forces to fight war in a nuclear environment, meaning to be able to fight in a contaminated battlefield, and  have the equipment to enable one to do so.
This is one reason why the changeover from tube type electronics to solid state is slow in the going, as tube gear has a much greater tolerance to emp. Today I presume most electronics in RN Navy use to be solid state, and to have emp protection devices and protocols in place to protect said solid state devices.

Today you can actually buy an Akula modem from the maker in Russia, so why not equip every unit with the best and newest at least for compatibility's sake? Perhaps Russia is counting on commercial orders to ramp up production of gear and hide the cost in the volume sold, kinda like having your enemy buy your weapons for you. Wonder what the world market for a hf burst modem is. Also from the pics they're not very small and are likely heavy, I suppose the waveform could be written into a pc app for tx/rx.

Testing and development of new systems, communications and weapons both, is taking place in actual combat in places like Syria, and I wouldn't be surprised to find it in use in the Yemeni/Saudi war. Slcms launched from RN subs have overflown Iran to get to targets in Syria - a test and a message sent to the west at the same time. New tanks and antitank missile defense systems are being tested in Syria too. RN has port facilities at Tartus and Lataika Syria, ringed with S400 air defense artillery systems.

Wouldn't come as a surprise to find the recent incidents where US warships went off course and ran into other shipping was due to RN electronic warfare units testing new toys. Eastern Ukraine is also a testbed of Russian EW gear. Iran dropped a US drone and reverse engineered it because Russia gave them the means to capture the drone.

Very nice info, Josh.

Interestingly enough, 7630 kHz is also one of the nationwide/regional net frequencies for the Civil Air Patrol (listed as part of "Net 3" but part of their main HF-SSB channel lineup.

CAP and the Russian Pacific Fleet likely never bump heads, but it could happen if/when both ends are in darkness.

The most often propagating freqs for CIS Naval cw is 12464 (in use 0600 to 1800) before 1800Z and 8345 (1800 to 0600) after, some fool in Moscow messing things up for me. This timing is problematic as 12 is just starting to come in well when they switch to 8mHz wich often isn't propagating from there that early.

12464 was finally coming in with some sporadic traffic today, starting at 1500Z. Propa has been lousy lately. Cochannel with the cw traffic was intermittent weak ssb voice. Almost every xmission started with VVV and then rose and fell as propagation teased me.
Next time will have something with a waterfall listening to the traffic, that would make copy a lot easier despite interference and fading.

Rig was the illustrious IC775 with the DSP APF cw filter activated, resulting in a rather spectacular 80Hz bandwidth without much ringing at all. I was concerned that narrow of filtration might be keeping me from hearing those stas off freq, and it'd not take too much freq error to drop them off the edge of the filter, but considering the fading and interference I think the filter made the difference between being covered by cochannel plus bandnoise and a cw note.

I suspect a vertical will be best for this kind of game due the lower angle of reception, especially compared to a short ocfd aligned vostok (east) and zapad (west) when it should be aligned sever (north) and yuk (south) for best priyom (reception) of them rooskiis. I'm really strellyat (shooting) myself in the noga (foot) with this antenna (antenna).

Finally caught some traffic on 8345 this morning a bit after 0600Z when they're sposed to switch to 12464 for the day. Traffic was passed for several minutes, so the day/nite switchover time seems to be a suggestion rather than a maxim.

Got up late so didn't get anything from the greyline on 12464 like normal and thought the game was over, but was surprised to catch a lot of very weak cw a bit after 1400Z.

BTW, thanks for all the work you put into this thread Josh.

Glad you find it interesting, it's my tribute to those who taught me, and there are many.

On cw interpreters, here's an video on the subject comparing several;
https://www.youtube.com/watch?v=MRuFn1nnuoY

I find that decent code with no multipath can be correctly copied by the usual sorcerer and etc software decoders, but once a bad fist, qrm/qrn, or multipath appears, it takes a human to make sense of the mush. It's odd but you can hear multipath on a cw note after you've been doing it a while.
Worse yet is Russian Navy doesn't seem to issue keyers to its forces, it issues straight keys, meaning every operator is going to have their own element timings.

Found out the Bubnov is sitting off the coast of Morocco at the moment, so plenty of opportunity for multipath from there to here. Hearing RIW Moscow or RCV Sevastopol is sure to have multipath too.

Speaking of Moscow and Sevastopol, 12464 and 8345 are the primary ship to shore side of the duplex channel, the shore to ship side are;
RIW Moscow 9145, 11000, 14556
RCV Sevastopol 15586, 7566

I've compared several decoders; sorcerer in two versions, K500, WCODE, CW Get, and CW Decoder and they all pretty much perform about the same, perhaps CW Get is a bit better, while WCODE will translate Cyrillic morse - wich I am not good at at all. I let them run overnite or when I'm away or listening to something else with another rig.
One thing I noted is most all of them want about 15 percent cpu time, a bit high to my thinking, setting CW Get to 50 cw signals reduced it to 4 percent, much more to my liking.

CW Decoder dl;
https://download.cnet.com/CW-Decoder/3000-18511_4-75325058.html

Sorcerer dl;
http://www.kd0cq.com/2013/07/sorcerer-decoder-download/

One thing I find useful is to set the input freq of the decoder app to twice the cw note freq.
For example, I always employ 600Hz bfo offset, all cw copied ota will be at that 600Hz tone. Setting the decoder to 1200Hz will allow the second harmonic to trigger the decoder rather than the actual tone at 600Hz plus all the band noise, of course one must make sure a second harmonic is present in the app for this to work - you will verify it in the fft when signals are present. The 1200Hz second harmonic will be pretty much completely free of band noise.

I've been thinking about a means to a better decoder app, one that perhaps employs a pll to;
 1 detect a sinewave
 and
 2 to ensure phase coherence wich will also enhance noise rejection (noise is incoherent) and define elements.
(Not that I know how every decoder works)
Then to have a buffer to copy elements into and look for the averages of an individual senders keying, dits, dahs, spacing, then apply these globally to the message for its entirety -- the above is why humans are better cw decoders than machines as we do all this without thinking about it.
I suspect that a decoder written with these features could decode cw that's beneath the noise floor, and humans can't do that. Smolinksi, I'm looking at you.
You could even determine/identify individual senders this way but that has been done for ages.

Lol using massive compute power of the most complex and modern design to decode the simplest of digital codes, dits and dahs, ones and zeros.

Seems I'm at just the right spot to hear RCJG and RHO62, wonder when some other calls will come along.

Something to keep in mind is the Ivan Bubnov will be in the company of a task force since she carries petroleum for the fleet, she replenishes the fleet allowing them to stay on station far longer than is she weren't present. When the Kuz (https://en.wikipedia.org/wiki/Russian_aircraft_carrier_Admiral_Kuznetsov) was plying the waves and not on fire in drydock like recently, Bubnov was in her entourage.
