Utility / Re: Den Helder Naval 6358.5 (CF) RTTY 0030 UTC 27 MAR 2023

Hi Sigint.

Quote from: ~SIGINT~ on March 27, 2023, 0047 UTC

...

Known loop message is:
02A 04B 06A 08B 12A 16X 22X 02A 04B 06A 08B 12A 16X 22X PBB
...

That is not that correct. This "loop" depends on what frequencies are activated and monitored for comms by PBB. As there are no units at see Den Helder will reduce watch and that will refelct in its CARB (Channel Availability and Receipt Broadcast).

Hope this helps.

Hi.

16805,0 kHz is irritating, as you cauhgt an FSK modulated signal. The central frequency for that is 16804,5 kHz and it is a well known DSC-channel in the maritime mobile service.

There are many stations from Chile listed there but I'd guess it is either Antofagasta Zonal Radio (CBA) or Valparaiso Playa Ancha Radio (CBV). A very hot catch could be Bahia Fildes Radio (CBZ22) from the Antarctic (-62.196342, -58.959383 / GC07MT).

Looking on Argentine there are the following stations on 16804,5:

Buenos Aires Prefectura Naval Radio L2G
Mar del Plata Prefectura Naval Radio L2U
Comodoro Rivadavia Prefectura Naval Radio L3B
Ushuaia Prefectura Naval Radio L3P
Argentina Radio LSD836

(Source: Admirality LIst of Radio Signals, ITU, IMO GISIS)

On the other hand there is NAVTEX-traffic on 16806,5 kHz but I have no stations from Chile listed there. But from Argentine there are tow entries in my database:

Buenos Aires Prefectura Naval Radio L2B / Sending NAVTEX at 1400z
Buenos Aires Prefectura Naval Radio L2C / Sending NAVTEX at 0030,0300,1000,1400,1530,1900,2100 (all times Zulu)

Just a tipp: ALways use the CF for FSK modulated transmissions - that may help to identify the station you caught much more easier.

Hope this helps.

Not helpfull - you don't need a tape, use a digital recorder.

Hi.

That's FAV22, French Forces with Morse-training.

Not really a numbers station.

Hope this helps.

Hi.

I have an entry in my personal database that it could be SHARES with ALE/MIL-STD 188-141 and voice. Maybe they use MIL-STD 188-110 either ...

Hope this helps.

Hi SigInt.

Could be FUV - F Ny Djibouti, which has been reported on 7000,1 kHz in the past.

Also possible is the RUS Ny on 7000,0 (reportedly Kaliningrad) with AT3004D-modem PSK.

Hope this helps.
