Today, I’ve heard some tests between « Lorient Ecole » & « vf »
Manual sent Baudot 75/850/i (offset +1400Hz) on 6721.0 USB then 5455.0 USB with plain voice coordination

« le » & « vf » were linked using another radiolink as « Lorient Ecole » operator voice has been heard in vf transmission

The Baudot on 6721.0 USB:

FAF new frequencies ?

Spotted recently:

20806.0 USB FAF CNOA channel ‘CAPITOLE’ & ‘FAF4010’ enroute towards West Africa

8021.0 USB FAF CNOA? channel ‘DAMO10’ with ‘GENERAL’
‘DAMO10’ gave ETA & ETA max to ‘GENERAL’ for him and also for LETHAL31 (unid)
DAMO is known to be the Grumman E-2 Hawkeye from the French Navy carrier Charles de Gaulle, last time I’ve heard him was during the Lybia2011 conflict..

I suppose those 2016 comms belongs to whatever happens nearby Mosul these days..

South African Navy MHF-50 modem test mode?

Heard a weird modem status on 13536.0 USB – March 10, 2016
4x tone mode, ascending scale (1000Hz > 1525Hz > 2040Hz > 2630Hz approx), repeating again & again…
I’ve made a quick comparison with usual MHF-50 mFSK heard on the freq:

13536_SAN

LEFT: MHF-50 mfsk – RIGHT: the stepping tones mode
each of the 4 tones are fitting fine with some MHF-50 tones, so it’s prob South African navy indeed..

FUG La Régine (Saissac, FR)

During last summer holidays, I had the opportunity to drive nearby the French Navy HF site named « La Régine »

Here is a far pic of the site, viewed from North, with « Les Pyrénées » mountains in the background
FUG_0001

I had bought a HF/RX there so I was able to confirm all those frequencies & modes:
FUG_slots

Note: some frequencies of that list are already not active anymore and/or mode has changed between RATT & S4285.. Those guys are working hard on setting up/down datalinks it seems..

Fore information: Taiwanese navy guys have changed their 2G ALE IDs in 2015..

ALE IDs logged so far:
BAAKG – BBRDA – BCQOW – BJVQF – BWFGG – BGX – BLF – BJVQF – BVWQT

Frequencies logged so far (this year):
14439.0 LSB (mco) – 16000.0 LSB – 16180.0 LSB – 17460.0 LSB – 18035.0 LSB (Nico)

They are sending 2x special AMD commands in their ALE net:
[AMD]AMDCHAT16 triggers [AMD] chat
[AMD]FAXDATA CK triggers MIL-STD 188-110 serial modem

AMD samples:

French Navy STANAG-4285 streams (replacing FSK-2)

I have noticed this weekend that the usual FSK-2 sent by the French Navy are no longer in use, looks like they were replaced by STANAG-4285 @ 600L (crypto.. of course..)

Those STANAG-4285 are easily recognizable on a waterfall because they have a ticking noise on each edge of the 2400Bd 8-ary waveform as shown on the screenshots below:

FNavy4285
4325.0 USB & 4338.0 USB on this one.

FNavy4285-2
4325.0 USB & 4338.0 USB   &   6430.0 USB on this one.

note1: the ticks aren’t sync..
note2: 8517.0 USB & 16966.0 USB are also impacted by that modification
