Fuerzas Armadas Espanolas - ALE (tentative)


yesterday 24th November, starting from 1148z to 1230z, I heard on 10515.0 KHz/USB the following MIL-STD 188-141A ALE messages; it was the very first time I heard these ALE selcall/identities:

[1148][TO ][BCZMIV6NORTE   ][TIS][BCZMII6NORTE   ]
[1152][TO ][RT1NORTE       ][TIS][BCZMII6NORTE   ] rptd 1158,1200
[1204][TO ][BCZMI64NORTE   ][TWS][BCZMIV6NORTE   ] rptd 1206
[1209][TO ][SECTRANNORTE   ][TIS][BCZMIV6NORTE   ]
[1211][TO ][BRILATNORTE    ][TIS][BCZMIV6NORTE   ]

Handshakes are followed by MIL-STD 188-110A data interchange at various modes such as 50bps/L, 115bps/L, 150bps/L and 2400bps voice.

I had no idea who they are,  as far as I know no one heard the following IDs before my reception (I browsed logs from UDXF and from other monitor sites):

BCZMII6NORTE
BCZMIV6NORTE
RT1NORTE
BCZMI64NORTE
SECTRANNORTE
BRILATNORTE
   
Given that "norte" is the Spanish word for "north", it is probable that I heard assets from the Spanish Army (FF.AA. Fuerzas Armada Espanolas). I posted a message on the UDXF list and Ary and Kristian, respectively, confirmed my idea:

The Spanish military do have a Brigada de Infantería Ligera Aerotransportable “Galicia” VII (BRILAT) and also a Compañía de Esquiadores Escaladores BCZM II/66, so it could be a Spanish mil net (Ary reported)

the BCZMI64 is El Batallón de Cazadores de Montaña (BCZM) “Pirineos” I/64
http://www.ejercito.mde.es/noticias/2014/11/3813_Evaluacion_GTMAD.html
there are some news that the Brigade will be sent to Mali, after Afghanistan-Mission.
(if I understand it correct)
https://www.google.de/search?q=brilat+site:.es&sourceid=opera&ie=utf-8&oe=utf-8&channel=suggest&gws_rd=ssl#q=brilat+site:.es&tbm=nws
 
SECTRAN could be Secretaría de Transportes or Transmisiones  (Kristian) reported)

I added that SECTRAN could also stand for Secretaria Fuerza de Transición y Estabilización
http://www.defensa.gob.es/glosario/T/index.html#siguientes

So, at present, if Spanish Mil is the confirmed source, we should have:
BRILAT: Brigada de Infantería Ligera Aerotransportable “Galicia” VII
BCZMII6: Compañía de Esquiadores Escaladores BCZM II/66, Batallón de Cazadores de Montaña
BCZMIV6: Batallón de Cazadores de Montaña (BCZM) [...]
BCZMI64 Batallón de Cazadores de Montaña (BCZM) “Pirineos” I/64
RT1 Regimiento de Transmisiones 1
SECTRANSecretaría de Transportes or Transmisiones ? Secretaria Fuerza de Transición y Estabilización ?

Suffix NORTE (north) is still unclear.

"The Crackle" (XC) is still alive


Heard on 14th November, 2110z at 8112.0 USB a wierd crackling noise just sounding like  "The Crackle": it's still alive on HF?

The Crackle, or Enigma designator XC, was first heard interfering VOLMET stations, its origin is unknown.The signal does not carry any information but rather it's a "noise" signal.

A short recording of the (prob) XC reception can be heard here

CIS FSK 200/1000


FSK 200/1000 is a technical name for a digital mode used by Russian Intelligence and possibly also Diplomatic stations. The name stands for its baud rate and shift - 200 bd speed, 1000 Hz shift between tones.

Aggiungi didascalia

The messages are encrypted bitstreams, sent in 288-bit blocks. Each block begins with control bytes 0x7D 0x12 0xB0 0xE6. The first two blocks of each message are significant, containing information on the amount of blocks, communication link ID, day of the month, serial number, message type, possibly the amount of encoded groups, and encoded decryption information.
A short recording may be heard  here

Below is an example of a FSK 200/1000 decoded transmission: you can see the mentioned keys (link ID, day of the month,...): reception was made on 17 November at 2020z, on 8123.0 KHz/USB:

FSK 200/1000 also has a concept of empty messages. These are always 4 blocks long, and include "00000" groups.
FSK 200/1000 operates in schedules of three transmissions, spaced 10 minutes apart.
The further transmissions are transmitted on lower frequencies. The frequency usage indicates worldwide operation. There also are unscheduled transmissions, using the communication link ID "00000", which may not repeat in regular manner.

FSK 200/1000 contents can be decoded using the free program Rivet, as in the following screenshot:

XSL - the "Japanese Slot Machine"

Japanese Slot Machine (also named XSL or JSM) is a system thought to be from the Japanese Government or Self-Defense Force (Navy). Some have likened its weird sound to that of a Las Vegas slot machine, so the name Japanese Slot Machine.
I heard an XSL transmission on 16 November (at 2212z) on 8588.0 KHz/USB: see below a screenshot from my SDR Console during the reception.


Known Frequencies
4231.5 kHz     6417.0 kHz     8588.0 kHz        
4291.0 kHz     6445.1 kHz     8704.0 kHz


The signal transmits continuously on pairs of frequencies in the 4MHz, 6MHz and 8MHz bands, which places it firmly in the ITU bands allocated for Maritime use.
Reports show the signal to be stongest in the Far East, indicating an origin in that part of the World. Although the signals are weak in Europe, they can be monitored in the evenings on both the 6MHz and 8MHz frequncies. The poor reception makes analysis of the signal difficult.
An article in Monitoring Times, December 2002 was the first to identify these signals as Japanese Navy. Writing it the "Utility World" column, Hugh Stegman outlines his reasons for this claim. Firstly, direction-finding fixes indicated Japan at the source of the signals, although China and Russia were not ruled out.
Secondly, the frequencies correlate with those previously used by the Japanese Navy for eight-tone radio modems, some of which disappeared at the right time.
Finally, monitors travelling to Japan identified additional strong local frequencies, some of which were only operating on a part daily basis.

The mode being used is quadrature phase-shift keying (QPSK) , encrypted shore to ships traffic.  The mode is un-decodable: Sigmira doesn't really decode the information but only displays the "frames" and raw QPSK symbols.


It still remains a challenging and difficult signal to monitor at any reasonable strength in Europe.

The following is quoted from the Sigmira manual.
"With some investigation the symbol rate was determined to be 1600.00 baud. The regular ticking sound was found to be an exactly repeating sequence of symbols. Clearly that serves as a channel probe and frame synchronization pattern. 
One tick sound period is here defined as a "frame". Frames were found to consist of 140 QPSK symbols. So the frame rate is 11.42857 Hz. 
The probe/sync pattern is 28 symbols which is one fifth the number of symbols per frame. It is found that, during the repetitive melody idle time, the remaining symbols of a frame consist of four repetitions of another 28 symbol pattern. So a frame appears to consist of five "blocks" of 28 symbols. 

During idle time there is a finite set of symbol patterns that appear in the blocks. The patterns are designated here: ps, p0, p1, p2, p3, p4, p5, p6, p7, p8, p9, p10, and p11. The "ps" pattern is the probe/sync pattern. The rest are numbered roughly in the order of their frequency of occurrence. The "p0" pattern is most common. The melodic idle time consists of an exactly repeating sequence of 64 frames. A 64 frame sequence is called a "super frame" here. 

The duration of a super frame is 5.60000 seconds. The frame / block pattern of the idle super frame is presented in the following table. The melody arises from the regular repeated simple patterns of symbols/phases. The p10 pattern is all one phase. So it produces a single tone. The p11 pattern is also all one phase but 180 degrees from p10. The other patterns are somewhat more complex and result in different and multiple apparent tones."

"S" Cluster Beacon (Severomorsk)


Yesterday eve I heard for the first time the couple of cluster beacons S D, while usually the couple that is heard is C D. I heard the "S" on 8494.6 KHz at 2036z.  Note that in the main waterfall (below in the reception window) you see only the D beacon: this is received with a stronger signal to my antenna given its relative proximity (Sevastopol, about 1800 Km)) compared to beacon S that comes from Severomorsk, about 3200 Km far from my antenna.


The location of the "S" beacon has often been discussed. Arkhangelsk was mostly mentioned as possible location. Murmansk is another one. Neither one is correct, though. The location is Severomorsk, near Murmansk. Severomorsk is the big military port and airfield complex, Murmansk is 99% civilian. Arkhangelsk is largely abandoned except for units supporting the building and trials of vessels.

ARQ-E (ARQ-1000, ARQ-N)

The ARQ-E (also known as ARQ-1000D and ARQ-N) is a single channel duplex ARQ system made by Siemens and mainly used by French Military Forces. Many signals idle for long periods of time in order to maintain links up and send very little traffic.

ARQ-E uses FSK modulation and operates at symbol rate of 46.2, 48, 50, 64, 72, 86, 96, 144, 184.6, 192, and 288 Baud with different shift values: the system can be adjusted with different gear variants to support user requirements.


ARQ-E/184-6/850                                                                                      ARQ-E/184.6/388

ARQ-E/184-6/850                                                                                      ARQ-E/184.6/388

 ARQ-E synchronization may be started by the selection of a baud rate. An AUTO program
start causes the automatic determination of the frequency shift and baud rate to be executed first. The signal polarity (USB or LSB sidebands) is automatically detected.
After synchronization to an ARQ-E system has been achieved, the detected repetition rate is displayed (4 or 8 cycles). This parameter may give clues to the identity of the transmission.
If a continuously repeated character (often FFFF) is decoded whilst working in the ARQ-E mode, it is most likely an ARQ-E3 system being monitored. ARQ-E employs the ARQ-1A alphabet with parity checking which allows the detection of transmission errors.
Full-duplex systems transmit a RQ character after having detected an erroneous character or in the presence of excessive signal distortions. The remote station subsequently repeats the last three, four or seven characters preceded by the RQ character.


To maintain synchronization between the two stations both transmitters operate continuously and send the idle bit pattern if no traffic is transmitted.

 

ARQ-E alphabet
Using the 7 bit ITA 2-P alphabet with 4 or 8 character repetition cycle, inverting every 4th or 8th character to facilitate block synchronisation.
Each 5 unit character arriving from the landline connection is converted very easily into a 7 unit code. The first bit of the 7 unit code is used as a "character identifier element". It identifies the character as either being a traffic character or a supervisory or control character. If it is of start polarity if the character is a traffic character, and of stop polarity if the character is a control signal, such as a idle Alpha, Beta or an RQ.
There then follows, for bits 2 to 6, the normal 5 unit telegraph ITA-2 code used on the landline connection. The 7th bit is a polarity bit. It is chosen so that the total number of stop polarity bits will be an odd number. If an even number of stop polarity bits results from the first 6 bits of the 7 unit code, a stop polarity element will be added as the 7th bit. If on the other hand, the number of the stop polarity elements is found to be an odd number, a start polarity element will be added.


Although only a 4 or 8 character cycle has been mentioned above, there is also a special 5 character block length. When using on-line crypto, it is extremely important not to lost any characters in the continual stream of random traffic characters. To ensure that a RQ block is not missed for what it is, a double RQ is transmitted. The sending of a double RQ character thus ensures that the sending station is fully aware that a repetition was requested.
There is also a SELCAL facility. When a station is called with its station number, it automatically brings up the transmitter and returns its selcal number back and enters the idle Beta signal state. When traffic is finished, either station can send a special cleardown signal which is also acknowledged but turning off both transmitters.

ARQ-N is identical to ARQ-E except that all characters are Erect, i.e. there are no character inversions every 4 or 8 character cycle.

why HF ?


in the age of Internet and Satcom why they should still use HF?

Prior to the launch of communications satellites in the 1960s, high frequency (HF) radio was the principal means to communicate over the horizon. Satellite links permitted users to communicate at higher data rates, and over time HF was relegated to a backup role within the militaries of the United States, Western Europe, and the former Soviet Union. However, the limitations of satellites became clear in the Cold War era, as satellites were not only vulnerable to jamming and physical damage, but also required a supporting infrastructure that was expensive to build and maintain. The last two decades have resultantly seen resurgence in HF radio, led by a new generation of automated equipment with improved link reliability, connectivity, and speed that offered many of the benefits of satellite technology at a fraction of the overall cost. HF now serves as the principal backup in most ground- and ship-based configurations, and the primary backup in installations prioritizing lowest total cost of ownership.

Today, amidst the post 9/11 requirements for continuity of operations and a failsafe means of voice and data communication, HF equipment serves as a critical component in most emergency preparedness wireless communications plans. HF radio provides an additional layer of protection against total loss of communication when infrastructure-dependent communications are disabled, destroyed, or unavailable.

Benefits of HF Technology:

MINIMAL INFRASTRUCTURE REQUIREMENTS
An HF radio network requires absolutely no infrastructure. Unlike conventional land lines, cellular and satellite telephones, and Voice Over IP, an HF radio user can communicate with another HF radio user without any infrastructure apart from the equipment and housing area, minimizing both cost and susceptibility to damage.
   
MINIMAL COST OF OWNERSHIP
HF is the most economical means of failsafe communication. After the initial investment in equipment and installation is made, there are no call or line costs. Furthermore, such equipment is ruggedized and built to withstand extreme conditions over many years, thereby significantly reducing costs of the usage period.

TRUE HEMISPHERIC COVERAGE
HF, or short-wave, radio is the best suited technology to communicate over long distances. When coupled with solid-state kilowatt amplifiers, HF can serve as a primary or emergency means of communication to and from any point in the world.

SURE AND SECURE COMMUNICATIONS
For sensitive communications where security is essential, voice and data encryption is a readily available option with HF radio with differing levels of security based on the respective communications requirement.

FULL FEATURED
In addition to voice, HF radios come with options that allow for telephone, fax, email, and high speed data.

INTEROPERABILITY
HF radios can communicate with existing VHF and UHF systems, cellular telephones and land lines through developments in cross-patching technology.
