Defence High Frequency Communications Service (DHFCS)
United Kingdom Communication systems - Joint


 

Description

The Defence High Frequency Communications Service (DHFCS) provides long distance strategic communication between Army units, RAF aircraft, Royal Navy warships and UK headquarters using HF communications.

It has subsumed the following legacy systems:

 

Base of operations

The system is based on six sites in the UK and four overseas.
In the UK they are Crimond, Inskip, Kinloss, Forest Moor, Penhale Sands and St Eval.
Overseas sites are Cyprus, Gibraltar, Ascension Island and the Falklands Islands.

The Network Control Station (NCS) is at Forest Moor (TASCOMM); it controls all DHFCS assets worldwide. The alternative network control centre (ANCS) is at Kinloss.

The system includes Automatic Link Establishment (ALE), Automatic Repeat Request (ARQ) and Automatic Link Management (ALM) and provides both voice and data services.

DHFCS was declared in service in March 2008 with the delivery of the ANCS at Kinloss.

Network Frequencies

There are H24 (flightwatch) operations centres at DHFCS Forest Moore and DHFCS Kinloss

GROUND CONTROLLED INTERCEPTION

On HF the following air defence radar stations can be heard.

Buchan, Boulmer ,Neatishead, Benbecula

Frequencies in use are from the same pool as the STCICS above. On any day you can hear stations ask Architect for designator frequencies to work with the three above, mostly Neatishead.

GUIDE TO MONITORING STCICS
-To find which frequencies are active listen to the Architect weather broadcast at H+00 and H+30 (see above).
-If the UKADGE circuits are active there will be an announcement following weather with code letters for active freqs.
EG '...additional information 2..PK..tack..401C..tack..AG (repeated twice).

-The first number indicates which air defense radar is active.
1- Buchan, Boulmer, Benbecula
2- Buchan
3- Boulmer
4- Neatishead

-The first 2-letter group is the code for the active HF frequency from the list (above), sometimes refered to as the Jorsk Frequency. This is the main operating frequency.

-The third group is the Charlie Squared channel, where AWACS aircraft pass their radar data. 

Channel  Frequency
401A 2250.5
401B 33?
401C 4478.5
401D 6673.5
401E 8500.5

 -The final group is 'chick co-ordination' where HF capable combat aircraft can be passed target information, etc.

-Therefore the EG given would be Buchan as ADR, using 5095 KHz for voice traffic, AWACS on 4478.5 KHz and 'chicks' are on 4745 KHz.

A new set of codes seem to be being used by RAF and other NATO forces. The 'K series' (real name unknown).
