1. Introduction

CIS Navy Morse networks are, to a great part, for training and backup purpose and since many years the same callsigns are used. Some callsigns show up again after years, others are called virtually weekly.
The fleet headquarters, airports, ATCs and aircrafts of the Naval Air Transport can, in many cases, be identified.
Ships sometimes report their position according to 1.11. FM13-Code Meteorological Data . This is rarely the case and happens around 00, 06, 12 and 18 h UTC, sometimes at 03, 09, 15 and 21 h UTC as well.
Some utility specialists keep track of ship movements, mostly during exercices in the Mediterranean, and try to assign the callsigns. Thanks to Tom, who does a great job and shares many of his observations with UDXF, the following list of ships/callsigns, of course it is not confirmed, became possible (as per 02.2013).

Ships/Callsigns

2. Allocation of Call Signs

Headquarters may use several callsigns; RAA and RJE56 for example are used by RIW operators in certain cases. All digital modes are encrypted, therefore other callsigns may be used in that traffic.

A spreadsheet with CIS Navy callsigns/traffic can be downloaded here: Downloads

The Navy callsigns have the following formats (L = letter, F = figure):

3. Special Purpose Callsigns

There is a series of call signs which are used for a certain purpose or by certain stations.

Naval Air Transport
As Aircrafts use 5-figure registration codes, they can, in many cases, be identified.

Collective Call Signs
Collective callsigns not only will address a fleet or task force, but as well certain waters. Warnings or weather forecasts for RGX94 concern French regions, RBE86 the Ionian Sea, RIP90 Turkish regions and the Aegeis and RKZ the Mediterranean Sea. REO means the Baltic Sea and RLO the North Sea.
If these my assumptions are fully correct, I don't know and am interested in more info.

The RJxxx Series Call Signs
These stations do not use the primary frequencies 8345 and 12464 kHz, but work in Simplex mode on frequencies like 8120, 8128, 10796 or 13469 kHz.
These are some callsigns:
RJC66
RJD25, RJD35, RJD36, RJD38, RJD46, RJD52, RJD69, RJD71, RJD77, RJD80, RJD85
RJE56, RJE58, RJE65, RJE67
RJF48, RJF95, RJF96
RJH25, RJH41, RJH57, RJH63, RJH90

Trond for UDXF assigned station RJE56 in Manikhino (Moscow) at 55N53 36E57 to the 301st Central Comms Point, Mil Unit 49383. Other sources said this is home of RIW Navy HQ, which supports the fact, that RJE56 belongs to RIW.

RJE65 is said to be at Boriskova, near Novorossyisk, at 44N44 37E41. Possibly this site is abandoned however.

RJH45, RJD38, RJF41, RJE73, RJH74 are addressed by ships to drop Sea State and Weather Data.
RJH69, RJH99, RJH66, RJH63, RJH77, RAB99 are NAVY VLF comms stations/Time Signals
RJF94, RJC38, RCH84, RJC48, RCB are Naval Aviation ATCs.
