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!

monitoring unid TSCP ALE identity: UPDATE

WOW... we have IDed the TSCP suffix finally as well: 
US Army, KFOR MNBG-E's "Southern Command Post" 
which is at Camp Bondsteel in Kosovo (MNBG-E: Multinational Battle Group-East). So far, we have frequencies 8935.0, 9005.0 and 9038.0 KHz/USB.

monitoring unid TSCP ALE identity

Reading some UDX Logs I noticed an interesting post from Kristian about unid  MIL-STD 199-141A trasmissions heard on 9005.0 and 9038.0 USB Khz. So yesterday (21 june) I parked two FDM-S1 V-receivers on those frequencies, monitoring  from 1400z to 1800z. These two receivers were connected via VAC to multipsk and PCAle,  ready to intercept and decode the unid MIL-STD 199-141A (ALE) trasmissions. 
Well, as reported by Kristian, I could receive soundings from the only ALE identity TSCP and just every 30 minutes (about), more precisely at hh:21-23 and hh:51-53. Other than Kristian the same recpetions (day and frequencies) have been logged by Ary and Bruno, both from UDX.

Since the 30 mins candence, could it be a US-Army Unit?

Bears Net (Russian Air Force)

AF Tupolev TU-95MS Bear



8895.0 kHz is a very interesting Russian Air Force CW frequency. The W beacons have been around for years and now UDXF monitors have found that these beacons may be related to Russian AF Tupolev TU-95MS Bear aircraft activity. 


Milcom Monitoring Post published a very interesting page about the activity on this frequency: the page can be read at russian-air-force-8895-khz-cw-w-markers

pillole NDB (aka "lo sapevo...")

...infatti evitavo consapevolmente quella fetta di frequenze perche' sapevo che in quella zona il virus della NDB-mania e' micidiale, e mi sa' proprio che sono stato contagiato.

NDB (acronimo di Non-Directional Beacon) è un trasmettitore a propagazione omnidirezionale, operante nella banda LF/MF, posto lungo le aerovie ed in prossimità degli aeroporti. NDB, è un radiofaro non direzionale molto diffuso, assieme al VOR, e usato per la navigazione aerea strumentale (IFR). L'NDB lavora su frequenze comprese tra 200 e 1750 KHz, trasmettendo un segnale audio, attraverso la quale lo strumento comunica il suo identificativo in codice Morse e fornisce all'aeroplano riferimenti che consentono al pilota, tramite lo strumento ADF (Automatic Direction Finder), di risalire alla direzione di volo . Vista la banda in cui opera, le onde radio emesse da un NDB seguono la curvatura terrestre (essendo riflesse dalla ionosfera) e pertanto il segnale può essere ricevuto, anche a basse quote, a grande distanza.

Il nominativo della stazione costituito da due/tre lettere in codice Morse e' trasferito sulla portante ad intervalli regolari con un processo di modulazione di classe A1A (o CW) o A2A. L’emissione in A1A è usata normalmente per i radiofari di navigazione; quella in A2A dagli NDB di avvicinamento. Piu' precisamente: 

A1A (CW, Continuous Wave)
interruzione di portante o Radiotelegrafia cioè la frequenza in AF, o portante, viene interrotta seguendo il ritmo del nominativo e seguito in Codice Morse. NDB di questa categoria sono principalmente quelli Francesi e della realtà coloniale francese es. quello a kHz 349,5 il “SZA” Solenzara-Corsica, quello a 359 kHz il “LOR” Lorient-Francia quello a 369 kHz il “BP” Bastia Porretta-Corsica ecc
.

SZA in modalita' A1A


A2A (AM, Amplitude Modulation)
il segnale in BF, cioè il nominativo in Codice Morse, modula una portante in AF e come risultato avremo la frequenza nominale, quella cioè che identifica l’NDB, più le due Bande Laterali ( Inferiore e Superiore) che contengono il suddetto nominativo. La distanza tra la frequenza nominale e una delle due Bande Laterali si chiama Offset o Shift e può essere di 1020 Hz ed è relativo a Radiofari Italiani, Tedeschi, Spagnoli ecc.  Capita anche che le due componenti in banda laterale non siano equidistanti dalla portante a freq. nominale.

TAQ in modalita' A2A (si notano le due bande laterali con la stessa informazione)


Gli NDB si dividono in tre classi e rispettivamente:
NDB di navigazione - Utilizzati per la navigazione in rotta, posti lungo le aerovie con una copertura di circa 100 NM (miglia nautiche) 
NDB d’avvicinamento - Radiofaro a bassa potenza di emissione, posto in vicinanza degli aeroporti, usato nelle procedure di avvicinamento “non di precisione”; ha una portata di circa 25 -50 NM. 
NDB “Compass Locator” - Radiofaro a bassa potenza d’emissione, usato come supporto all’avvicinamento ILS; ha una portata limitata di 25 - 30 NM.

La strategia di ascolto, indipendentemente da NDB A1A o A2A e quindi dalla frequenza di sintonizzazione, si basa sull'avere a video lo spettro del segnale per ricavare la esatta sequenza di punti e linee e quindi passare alla traduzione dal codice Morse. Un consiglio consiste nell'utilizzare un filtro di media frequenza strettissimo, di almeno 500 Hz (meglio se 250). 
Un valido aiuto sul web e' sicuramente il sito classaxe sul quale effettuare la identificazione dell'NDB in base all 'identificativo ricevuto o alla sua frequenza nominale.L'amico Roberto Rizzardi, che ringrazio, mi indica un post del suo ottimo blog in cui spiega l'utilizzo di un utile software, comodo per le  identificazioni NDB ed i rapporti e che qui rigiro a favore di tutti gli appassionati:
