Australian Defence Force MHFCS HF Frequencies

Australian Modernised High Frequency Communications System

The ADF  Modernised High Frequency Communications System (MHFCS) is a HF radio network providing communications services for the operational control of Australian Defence Forces (ADF) and allied aircraft, HF equipped marine craft, and land units.
In addition, visiting military aircraft may use either the ADF or RNZAF's system when contact with Australian / New Zealand based military authorities is required.
Neither system provides a civil or military air traffic control service.

This is a shared NAVY, AIR FORCE, ARMY network, however, you will primarily hear RAAF aircraft and Army training facilities on the net.
Most communications occur on VCN 3.

The MHFCS is controlled remotely by Defence Communications Station Canberra (DCSC) at the Network Management Facility (NMF) located in Canberra.

The ADF MHFCS consists of four TX/RX Nodes located at:

NORTH WEST CAPE, WA (S22.20 E114.30)
DARWIN, NT (S12.22 E130.59)
TOWNSVILLE, QLD (S19.28 E146.25)
RIVERINA, NSW (S35.01 E146.25)

The DCSC provides 5  continuously monitored Voice Contact Nets (VCN), which consist of:

VCN CIRCUIT DIAL FREQUENCY HOURS OF OPERATION
VCN 1 22868 KHz H24
VCN 2 5878 KHz H24
VCN 3 9047 KHz H24
VCN 4 15962 KHz H24
VCN 5 12172 KHz H24

 

Mode Of Operation
DCSC is capable of operating Independent Side Band (ISB) or AM modes, however, the normal mode of operation is Upper Side Band (USB).
Digital modes may be employed for encrypted transmissions. It is possible that one of these modes is 2G ALE, ANDVT, or Stanag 5066, however message content is encrypted and it is an offence to decrypt such transmissions.

 

Registered frequencies available on the ADF MHFCS

Remember to subtract the correct bandwidth from the listed frequency to obtain proper dial frequencies.
(I.e. 12.6735 MHz 3K00J9W, dial frequency is actually 12.672 MHz - 2.145 MHz 6K00B9W is dial 2.142 MHz)

The purpose of the High Frequency (HF) Modernisation Project (JP 2043) is to provide the ADF with a secure, cost-effective information exchange capability for the command and control of deployed forces as a primary survivable system and as a parallel system to satellite communications.

The High Frequency (HF) Modernisation Project (JP 2043) is a part of the Radio Frequency Systems Program Office in the Communication Systems Branch of the Electronic and Weapon Systems Division of DMO.

The Modernised High Frequency Communications System (MHFCS) comprises a nation-wide network of distributed HF radio stations (the Fixed Network) with a central network management system in Canberra. The Project includes upgrading of HF radio systems in selected mobile platforms and transportable HF communication shelters (the Mobiles). The MHFCS is replacing some of the existing single Service HF fixed-mobile tactical HF gateways.

JP 2043 - HF Modernisation Project will replace the HF components of the Naval Communications Stations Canberra and Harold E Holt and the RAAF Air Operations Communications System stations (AOCS) at Darwin, Perth, Sydney and Townsville. The new network comprises four geographically dispersed remotely operated pairs of transmitter and receiver stations that are inter-connected by a Defence Wide Area Network and controlled by a Network Management Facility located in Canberra. The new stations are located at sites in the Riverina, North West Cape, Darwin and Townsville areas.

The project was scheduled for completion in 2010, however that was extended to 2012.

Project Information

General
The Modernised High Frequency Communications System (MHFCS) is being delivered in two major phases. MHFCS (core) delivers a common, ADF, HF communication network that offers comparable, but more reliable HF services than the existing single Service HF communication networks. MHFCS (final) will deliver enhanced capabilities that support automation of HF services, new HF traffic types and greater HF traffic capacity. Additionally, MHFCS (final) is intended to upgrade the HF communications capability of selected sea, air and land mobile platforms to take advantage of the increase in automation and improvements in technology, nut maintain compatability with legacy (non-upgraded) mobiles and the mobiles of allied forces.

Fixed Network - MHFCS (core)
The MHFCS (core) system replaces the existing single Service HF communication networks operated by the RAN and RAAF. MHFCS (core) provides a level of service that is commensurate with the capabilities of the existing single Service HF networks it replaces. It comprises a range of facilities, hardware and software that incorporate modern technology to deliver voice and organisational messaging capabilities over HF, as a key component of the ADF�s strategic and tactical communications infrastructure.
On 25 October 2004, the MHFCS core system was formally accepted from the Contractor, Boeing Australia. Acceptance marks the inception of the Defence Communications Station (DEFCOMMSTA Australia) which houses the Fixed Network and which is now under the day to day management of the Officer In Charge DEFCOMMSTA Australia.

DEFCOMMSTA Australia comprises a fixed network of four nodes, which are located at Riverina, Townsville, Darwin, and North West Cape. MHFCS (core) is controlled from the central Network Management Facility (NMF) in Canberra and has an interim Core Backup Network Management Facility (BNMF) which has partial functionality compared to the BNF. The nodes and the NMFs are interconnected via the Defence Secure Data Network. Each node consists of:

a. Transmit Station
b. A geographically separate Receive Station, and
c. Local Management Facility.

DEFCOMMSTA Australia is managed by Defence uniformed personnel and operated by a combination of Defence uniformed personnel from the RAN and RAAF, supplemented by a smaller number of Boeing operators. The MHFCS is wholly supported and maintained by Boeing Australia technical staff, including three technical staff at each of these nodes.

The new network comprises four geographically dispersed remotely operated pairs of transmitter and receiver stations that are inter-connected by a Defence Wide Area Network and controlled by a Network Management Facility. The new stations are located at sites in the Darwin and Townsville areas.

 

Mobiles and MHFCS (final)
The MHFCS (final) will build on the survivable, reliable, long-range secure and insecure tactical HF communications delivered by MHFCS (core), providing coverage on and over continental Australia and offshore to at least 2,000 nautical miles. MHFCS (final) is an upgrade to the MHFCS (core) system, which significantly improves the automation of functions in the fixed Network through the introduction of Automatic Link Establishment, Automatic Link Maintenance, and Automatic Call Maintenance. MHFCS (final) is also intended to deliver enhanced services over HF that include e-mail, interactive services, facsimile and file transfer. A major improvement at MHFCS (final) will be delivery of enhanced HF capabilities to Mobiles platforms, including automation and relay capability for mobile-to-mobile users via the Fixed Network. The automation intended for introduction to the Fixed Network and Modified Mobiles at MHFCS (final) will substantially reduce the manual effort involved in delivering HF communications. Furthermore, Modified Mobile users will experience no reduction in existing capabilities and will have total control over the system e.g. control of the use of HF assets for strategic or tactical requirements, such as entering EMCOM/RADHAZ modes.

The Project includes upgrades of the following:
