Russian Army Networks on CW


Courtesy of F5JBR Andre (http://f5jbr.free.fr/) who mantains the following lists. This is a work-in-progress by my friend Andre, years of experiences in CW:  at my side, other than collaborate with him in monitoring CW frequencies, I've translated and arranged his material. As said above, this is a work-in-progress: with your help and tips, we hope to keep it updated on on a weekly basis

notes:
All frequencies in KHz, times in UTC
CS = Control Station
SS = Secondary Stations (outstations)


The military in the former Soviet countries are still quite active on SW with voice and morse transmissions. From what we can trace, the majority of these transmissions originate from Russia and Ukraine. Although it is very difficult to find out find out who the stations actually are. As long as they are using the ITU callsigns it is often possible to find out who they are. Many of the naval and several air force callsigns have been located over the years. The army however uses tactical callsigns which makes it very hard to determine from what country they actually transmit.


Years are commonly divided in 4 periods:

  • spring : 1 mar - 5 may
  • summer : 6 may – 31 aug
  • autumn : 1 sep- 31 oct
  • winter: 1 nov - 28(29) feb
Most of the networks change monthly their identifier on days 1, 11 and 21 and so identifiers have a validity of 10-11 days average (except for the last period of February). Other networks change identifier every day and others do not ever change (but that's quite rare). Some networks operate on daytime frequencies starting from 0230 and night time frequency starting from 1700; other, respectively, starting from 0300 and 1730 or 1800. Still others change the operating frequency at 0500 (daytime) and 1900 (night time).

Networks are divided into three groups:

  • simplex  all traffic is carried on the same frequency
  • duplex 2 Tx frequencies are used, one for the Control Station and the other for Secondary Stations
  • broadcast Control Stations transmit on one or more frequencies, repeating the messages for two times; Secondary Stations never respond
 In any case it is always the control station that manages and coordinates the traffic (contact hours, the volume of exchange QTCs, frequency for testing, traffic flow, ...).

Just for your information: there is another possibility, but not yet identified, except perhaps the Russian Navy but it will be a future topic: it is the multiplexed networks: each secondary station, still under orders a control station, broadcasts on a frequency of its own but all stations on the network listens to the same frequency of the control station. Other frequencies were heard, including frequencies covering the night were. These tracks are scarce at the moment just because I am active especially on daytime.

Propagation' capricious and also the background noise at low frequencies, make difficult to cath and confirm new frequencies, I have several frequencies waiting, but they will come soon For the moment, it's no possible to have the definitive characteristics but with time it will come and the list will be updated.

By cons, if in "your frequency rides" you hear telegraphy on a particular frequency, do not hesitate to let us know: we still didn't manage to "pick" the diverse and scattered informations, your help is very apreciated.

So, please, send your CW logs to:
thank you so much!
