The GHFS was established on
1 June 1992 to replace and simplify the many different US Government HF networks
such as the Global Command and Control System (GCCS) and dedicated Strategic Air Command
Giant Talk system (SAC) networks and now stands as the primary US Dpt of
Defence (DOD) HF network.
The GHFS is a worldwide network of high-power stations which provide
Air/Ground HF command and control radio communications between ground agencies
and U.S military aircraft and ships. Allied military forces can also call upon
this network if needed.
General services provided by GHFS to authorized persons
are:
-
Emergency
Assistance
- Broadcasts
of Emergency Action Messages (EAM)
- General phone patch (pp) and message relay services
- Command and control mission following
- HF radio teletype (RTTY) and data support
- ATC support
- HF direction finding (DF) assistance
The best frequencies to
listen to, as the chart suggests, are 8992 and 11175 although in being in the
other hemisphere the signals can be considerably low from aircraft and a decent
shortwave antenna will be required for reception. AMC FREQS & more USAF
freqs shown at the bottom
This is the most up-to-date info on
the GHFS as at October 2002.

Shown below is a more print friendly
version, it is not as up to date, however is still fairly accurate:


Standard
Operating Procedures (SOP's):
Authorized users may request service from GHFS station by calling
"Mainsail". Any station in the net recieving the call will respond and
provide requested service. Minimum service by all stations are phone patch and
message relay service. Phone patch permits direct voice communication between
ground agencies and aircraft/ships by electronically connecting telephone
circuits or other voice channels to radio transmitting and recieving equipment.
For pp: callsign, telephone number and location should be stated if known.
When
contacting GHFS for RTTY, global will designate and alternate frequency for the
service.
EAM messages are common on all frequencies, only aircraft with
emergency or distress situations are to interupt EAM broadcasts made out by GHFS
using the static words "PAN PAN PAN" or "MAYDAY MAYDAY
MAYDAY". GHFS are not directly capable of Direction Finding. However
stations can assist in DF by coordinating between various aircraft in the
vicinity.
More often then not you will hear "REACH" aircraft requesting a pp to an airbases' AMC CP giving them a heads up about their load, passengers, estimated time of arrival and aircraft technical status. Almost always this pp is followed by one to the destinations airbase meteorological office to ask them the current or expected weather conditions before they land there. At the end of the pp to the wx shop on an airbase the pilot occasionally asks the meta man if he wants a PIlots REPort (PIREP) as an extra service, so the wx shops can give better forecasts on the weather for other aircraft and anticipate.
AMC Operations Center: The USAF Air Mobility Command Tanker airlift Control Center (TACC) at Scott AFB, provides worldwide service for AMC missions. Either TACC or appropriate AMCC can be contacted for airlift movement reporting or assistance through Global stations. Calls can be made out to:
| CALLSIGN | LOCATION |
| Denali | Elmendorf AMCC (Alaska) |
| Furious | Howard AMCC (Panama) |
| Brickyard | Osan AMCC (Korea) |
| Hilda East | TACC East Cell (USA) |
| Hilda West | TACC West Cell (USA) |
| Tracker | USAFE UTRACC (Germany) |
Note: Also the Air Force Eastern Test Range (AFETR) can be contacted as back-up on 10780 (pri) or 20390 (sec) under callsign "Cape Radio". Furthermore a new station has stepped in with callsign "Puerto Rico".
352 SOG, Mildenhall, UK
The 352nd Special Operations Group at Mildenhall AB operates several aircraft. Operations are using the callsign 'Blackhat'. For HF they have a wide array of frequencies available although the following are mostly used:
| D1 | 4888 |
| D2 | 5402.5 |
| D3 | 6691 |
| D4 | 11228 |
USAF KC-135, Det Istres, France
After operation 'Allied' force the USAF(E) still maintains a KC-135 detechment at Istres/le-Tube, France. Operations goes by the name 'Riviera Ops'. Their HF Operations are taking place on:
| OPS DAY | 11269.5 |
| OPS NIGHT | 8999.5 |
| A/A | 6761 |
Ramstein Airbase, Germany
Apart from the GHFS system, the 86AW
aircraft based at Ramstein have a specially formed HF service at their disposal
which can help them to make the missions a succes. The communication unit is
based at Ramstein and is using the callsign 'Metaphore' and uses the following
frequencies:
6819
6870
7919
14682
15082
Giebelstadt, Germany
| 13.273 | 'Big Windy' |
| 19.100 | Flight Following |
| 22.914 | 'Blue Star' |
| 24.750 | 'War Eagles' |
| 26.725 | Aviation Regiment Common |
Brindisi Airbase, Italy
Identical to Mildenhall, the Special
Operation Squadron here has a HF usage. Operations here are using the callsign
'Promenade'.
