"NSS" and "IDN" callsigns from Napoli

NSS: belongs to  Allied Joint Force Command (JFC)
IDN: belongs to Italian Navy
...but both the callsigns are operated from Napoli

Allied Joint Force Command (JFC) Napoli (in short JFC Napoli) is a NATO military command based just outside of the town of Lago Patria in the region of Campania (before it was based in Bagnoli, near Napoli). It was activated on 15 March 2004, after what was effectively a redesignation of its predecessor command, Allied Forces Southern Europe (AFSOUTH), originally formed in 1951. Commander JFC Napoli [1] reports to the Supreme Allied Commander Europe at Supreme Headquarters Allied Powers Europe, Casteau, Belgium.
 
Commander, Allied Joint Force Command Napoli, is responsible for conducting the full range of military operations throughout the NATO Area of Responsibility (AOR) and beyond in order to deter aggression and to contribute to the effective defence of NATO territory and forces, safeguard freedom of the seas and economic lifelines and to preserve or restore the security of NATO nations.

About the callsigns in STANAG-4285

Nato Allied Joint Force Command Napoli broadcasts CARB [2] messages such as:

NSS Joint Force Command CARBs

//NSS2I(0)/NSS3I(0)/NSS4I(0)/NSS5I(0)//
//NSS2I(0)/NSS3I(0)/NSS4I(0)/NSS5I(0)//
//NSS2I(0)/NSS3I(0)/NSS4I(0)/NSS5I(0)//

And sometimes you can also see messages reporting the code legends such as:

LEGEND:
I(N) IDLE
B BUSY
BQ BUSY (ARQ)
U UNREADABLE
K TRANSMIT
M REPEAT
N(01-99) RETRANSMIT
AS WAIT
R RECEIVED
C(2-16) CHECK


I asked some UDXF friends about the "NSS" callsign: below their comments.
Thomas M. Rösner answered:

 "US Navy use N-callsign for any of their (in cooperation, here for/by NATO) operated facilities around the world. In these STANAG transmissions, as you can see, they use the (ITU) NSS callsign for this station, which belong to the US Navy  (ex Annapolis MD [3], now "NAK") while before US Navy Naples used to be "NNI". Maybe they moved from US Navy COMMSTA's "NNI" to "NSS" while modified into a USN/NATO station, but I could be wrong."



"I believe the real NSS originates from the Davidsonville, MD complex and is alive and well on a number of frequencies with 50bd and 75bd secure FSK, Link-11 and STANAG4285. Sometimes ITU reports list it as “Washington”. I thought that the NSS CARB was associated with Rome, not Naples? Are they perhaps switching TX sites like a number of other Navies do with their STANAG4285 outlets (UK, Norway, etc)." , Mike Chace-Ortiz (aka mco) say.

So, these transmissions should not be logged (or confused) with similar STANAG transmissions which use the IDN callsign, since "IDN" is the callsign of the "real" domestic Italian Navy station there in Napoli. In fact, CARBs broadcasted by "IDN" report their own proper callsign:

//IDN2I(0)/IDN31(0)/IDN4I(0)/IDN5I(0)//
//IDN2I(0)/IDN31(0)/IDN4I(0)/IDN5I(0)//
//IDN2I(0)/IDN31(0)/IDN4I(0)/IDN5I(0)//



IDR Italian Navy Rome CARBs

 
Surely, both the two stations are controlled from Napoli, but two different stations/operators and "customers".

ISB (Independent Side Band) transmissions

As said in a previous post about Portoguese Navy [1] , the ISB (Independent Side Band transmission) system uses two SSB channels, which are independed to each other, added to form two side bands around the reduced carrier. So it can simultaneouly convey totally different transmissions.


Two different input signals modulate the same carrier frequency to produce two double-sideband (DSB) waveforms, then two band-pass filters are used to select the upper sideband and the lower sideband in the other.


The selected sidebands are combined to produce a final DSB signal in which each sideband carries different information. 
Since, the number of single-sideband (SSB) channels that can be transmitted over a given communication system is determined by the minimum frequency separation of the channels, using ISB mode, channels can be spaced closer together, and hence a further bandwidth economy can be achieved.

ISB mode is useb by Portuguese Navy in their STANAG-4285 trasmissions to carry encrypted traffic in the upper side band and CARBs messages [2] in the lower side band as in the following example:


Other examples of the use of the ISB and DSB (i.e. the same information on both the two lateral bands) mode can be found tuning some Link-11 [3] transmissions

Israeli Navy Hybrid HF Modem


This system is used by Israeli Navy, more likely from 4XZ station in Haifa, and it's quite easy to hear. The waveform is composed of  3 parts: a four tones (2 seconds length) preamble, the parallel-data part using QPSK modulation in channels at 75Bd speed and the final serial-data part according to the MIL 188-110 single tone (1800Hz carrier modulated with PSK-8 at 2400Bd). A variant with an added 230ms pre-tone at 1000Hz has been seen.
Since the low data-rate, the apparent ACF is 66.6 ms.

COTHEN ALE Network (4-hours monitoring)

Last night I parked the FDM-S1/SW2 receiver (an SDR) on 11494.0 KHz/USB, from about 0030z to 0430z, to monitor and catch COTHEN's ALE Network traffic and ALE addresses (11494.0 is one of the frequencies operated by COTHEN Network). 


COTHEN is an HF ALE network that uses landlines to connect nineteen transmission sites spanning the nation in order to form one unified coverage area. Currently, the network has 19 sites, 89 remote communications consoles (RCC’s), and a TSC in Orlando, FL.

Russian Naval Air Transport / Naval Aviation (M32b/RNAv)


Russian Navy   Russian Naval Air Transport / Naval Aviation   Russian Navy Morse
 
This short text does not claim to be complete or exact, it is just an attempt to collect and consolidate sparse notes about the Rus Navy way to Morse. I did examined my own logs, browse some Navy and Defense websites, mainly from Russia, N&O columns / Spooks newsletters, public available sources and public sites/forums on the web (later reported). You have to know that this document is always-under-construction and may be outdated, incomplete or even wrong. Comments are welcome.

The Russian Naval Aviation (Aviatsiya Voenno-morskogo Flota Rossii) is the air arm of the Russian Navy, having superseded the Soviet Naval Aviation.
The air forces of the most important fleets, the Northern and Pacific fleets, operate long range Tu-142 anti-submarine warfare aircraft and Il-38 medium-range ASW aircraft. Formations operating supersonic Tu-22M3 bombers were transferred to the Russian Air Force's Long Range Aviation in 2011. The relatively small fleets, the Baltic and Black Sea, currently have only tactical Su-24 bombers and ASW helicopters in service. The small Caspian Flotilla operates An-26 and Mi-8 transports, Ka-27PS rescue helicopters, as well as some Ka-29 and Mi-24 armed helicopters.
On July 15, 2014, a modernised version of the Ilyushin 38N anti-submarine plane was officially delivered to the Russian Navy. 
 

Naval aviation has a functional division into the following branches: Naval missile-carrying aviation, ASW (anti-submarine warfare) aviation, Attack aviation, Reconnaissance aviation and Auxiliary air units (of airborne early warning defense, electronic warfare, counter mining, guidance and communication support, aircraft fueling in flight, SAR, transport support and ambulance aviation).
Naval Aviation units are based in aerodromes and aircraft cruisers, divided into Shipborne and Shore-based Aviation.
 

As of 2012, the only fixed wing strike and fighter aircraft of Russian Naval Aviation are the Su-33 fighters and Su-25UTG attack aircraft of the 279th Regiment (forming the Admiral Kuznetsov's carrier air wing), plus the Su-24 bombers based in the Crimea. This sole bomber unit remained part of Naval Aviation as an exception to satisfy treaty requirements governing Russian forces deployments on Ukrainian territory (these must be part of the Black Sea Fleet). Buying brand new multirole Sukhoi Su-30SM for the Black Sea Fleet to replace Su-24 is in the planning stages. 
Naval aviation also retains the anti-submarine aircraft of the forces (the Tu-142 and the Il-38) and the helicopter arm.

* aircraft carrying cruiser "Admiral Kuznetsov"
the carrier (the only one of the Russian Navy) should have the callsign RKO81, but it's not absolutely confirmed. 


* Airport 
callsigns were 3-figure-codes in the past, today they give either normal ICAO Uxxx  codes or internal Xxxx codes (Xxxx is the same code as Uxxx).

Aircrafts
5 digit callsigns of aircraft correspond to the registration number and can be identified in most cases (only valid for Naval Air Transport fleet)

traffic

Simplex contacts with aircraft (5 figure codes) with flight status reports. They mix common ITU-Q-codes (e.g. QRE, QTH, QTR etc) and ICAO-codes (as QAY, QBG, etc) with internal codes (e.g. QQL, QQM).

QTC I have message for you.
QRV I am ready.
QTO I am airborne or I started at ... (hours).
QTR The time is ... (UTC used).
QRD I am bound for ... from ... .
QRE Estimated time of arrival at/over ... (place)is ... (time).
 
QAH Flight level/altitude is ... (in meters or barometric pressure)
QQL I have passed ... (place) at ... (time).
QBD Fuel endurance is ... (hours and minutes).
QAL  I estimate to land in ... (place) at ... (time).
QQM I will land in ... (place) at ... (time).

JJC/9VF Kyodo Radio FAX

KYODO NEWS FAX reception on 10 September (1910z)

KYODO NEWS, founded in November 1945 as a nonprofit cooperative organization, is the leading news agency in Japan.Kyodo distributes English-language news, known as Kyodo World Services (KWS), to Japanese and transnational media 24 hours a day on a real-time basis. Subscribers include the head offices and Tokyo bureaus of major newspapers, TV-radio stations and electronic news media in Asia, the United States and Europe. They use KWS mainly as a first-hand source of information on Japan and the rest of Asia. KWS is also sent to international organizations and Japanese diplomatic missions throughout the world.

HF-FAX service
Kyodo issues newspapers, both in Japanese and English, that are radio-transmitted twice a day to about 800 ocean-going ships and fishing boats, and hotels in resorts abroad. First published in 1964, the newspapers marked the 30,000th edition in October 2007.
Radio stations JJC in Japan and 9VF in Singapore (not affiliated with the meteorological agency) are directly operated by Kyodo News and they are the last marine weather fax station which faxes daily news and navigational warnings.
JJC and 9VF are listed in the guide written by the National Oceanographic and Atmospheric Administration (NOAA) of the US (available here). Informations are dated March 1, 1999 and provided by Kyodo News April 2001.

XPA (CIS MFSK-20)


This is a Russian mode also known as CIS MFSK-20 believed to be used by at least one of the Russian intelligence services. It transmits data at either 10 baud (most commonly) or 20 baud using a 17 tone MFSK system. The name CIS MFSK-20 comes from the whole pool of the available frequencies although only 17 of these are used, sumarizing the initial sync part and the message part of an XPA transmission (Pic.1). Measuring the frequency grid inside the message you get a value = 14 (Pic. 2) and it could lead to wrong conclusions about the number of the frequencies used in this system. There are "holes" related to frequencies that are not in use or have special/unknown functions.

Baudrate can be measured by the scan-raster method (Pic. 3): as you can see, in this recording the baudrate is just 10 Baud.

MFSK in pillole


MFSK (Multi Frequency Shift Keying) è una tecnica per trasmissione di dati digitali che usa toni multipli (multitonale) a differenza della tecnica FSK la quale usa due soli toni (bitonale). 
In poche parole, invece di due frequenze come in FSK  se ne usano 4, 8 o 16 (rispettivamente 4-FSK, 8-FSK e 16-FSK) o un numero maggiore, fino a 64 toni. In questo modo ogni simbolo, essendo composto da piu' toni,  trasporta più di 1 bit e la maggiore velocità raggiunta può essere usata a favore della rapidità di trasmissione, oppure per rendere più robusto lo scambio dei messaggi.


Come altri modi di derivazione militare, MFSK e' stato concepito per offrire una una buona immunita' alle cattive situazioni di ricezioni dovute effetti ionosferici, quali l’effetto doppler, il fading e multi-path senza la necessita' di ricorrere a meccanismi di correzione di errore. Ne sono un esempio i sistemi Piccolo e Coquelet  usati nel passato nel passato dal British Foreign Office, dall'Esercito Belga e Francese ed altri.
Il vantaggio maggiore  è che il livello di errore migliora man mano che il numero di toni aumenta, di modo che con un sistema a 32 toni, i risultati sono ineguagliabili.  Di per contro, MFSK utilizza una maggiore larghezza di banda per una determinata velocità di trasmissione nei confronti di FSK o PSK, ma, come visto, e' senz'altro più affidabile.
MFSK usa una spaziatura fra i toni relativamente stretta cosi' che vengono raggiunti buoni indici di dati per una bassa larghezza di banda: classico e' il valore di 64 bps (circa 80 parole al minuto) in una larghezza di banda di soli  316 Hz. Vale la regola  che i toni trasmessi debbono essere spaziati da una separazione equivalente alla velocità di trasmissione in baud, pena la difficile separazione di un tono dall’altro all'atto della decodifica della trasmissione.

Ma come vengono trasmessi questi toni?
Ci sono numerose “famiglie” o tecniche MFSK che usano toni paralleli (ovvero trasmessi simultaneamente), toni sequenziali (ovvero trasmessi singolarmente uno dopo l’altro) e combinazioni di questi. Ad esempio MT-Hell può essere sia parallelo che sequenziale, i toni DTMF usati per la segnalazione telefonica sono toni sequenziali a coppie (un mix dei due modi) cosi' come Piccolo e Coquelet.

Come visto nel caso di AFSK, il trasmettitore non varia la propria frequenza di trasmissione bensi' modula la portante principale con il segnale multitonale MFSK  che e', ovviamente, in banda audio.
In virtu' dei multi toni usati le trasmissioni MFSK sono facilmente riconoscibili dal loro particolare suono, quasi musicale: da qui i nomi  Piccolo (francese per “ottavino”) e Coquelet (gallo). Ugualmente ben riconoscibile e' Olivia (nelle sua varie declinazioni), usato sia nei QSO degli OM che nei radiogrammi trasmessi dalla VOA. Nel caso di Olivia, si e' soliti indicare i vari sistemi con la dicitura Olivia X/Y dove X indica il numero di differenti toni trasmessi e Y la larghezza di banda impiegata.
Oltre ai gia' menzionati MT-Hell, Piccolo, Coquelet e Olivia, sono altresi' sistemi MFSK i vari THROB, DominoEX, MEPT_JT, THOR,.. cosi' come CROWD-36.
