2012 Chatham County Hurricane Frequencies

Amateur Radio

In the event of a hurricane, Amateur Radio would of course play a large part in the response to the storm. Georgia Amateur Radio Emergency Service (ARES) would activate to support state and local emergency management. Other organizations would activate to respond to the hurricane in other capacities.

ARES, when activated will use several 2-meter repeaters for local area, point-to-point traffic. Should the repeaters fail, the initial 2-meter fallback simplex frequency would be the National Calling Frequency. HF frequencies would be used for more long distant communications including communications with statewide ARES and emergency management stations.

A good way to keep track of and to gather information on a hurricane is the venerable Hurricane Watch Net, which has been around since 1965. This net will activate whenever there is a hurricane within 300 miles of a populated land mass or when activation is requested by the National Hurricane Center. The purpose of the net is to gather information from the storm for the National Hurricane Center and to pass on National Weather Service advisories on the storm. Information on hurricanes can also be heard on the Maritime Mobile Network. They also collect information for the National Weather Service and pass weather service advisories.

Local public safety agencies would be in the front lines of hurricane response. A listing of agency frequencies and Chatham-Effingham Trunked Repeater System (TRS) talkgroups would be too long to list here, but can be found on the system’s RadioReference page.  There are emergency management, mutual aid, and common frequencies and talkgroups that would be good to include in scanner programming. These would be used by a wide variety of agencies during any multi-agency response.

Many of the talkgroups on the Chatham-Effingham TRS have equivalent talkgroups on the new Southeast Georgia Regional Radio Network (SEGARRN), which has sites in Bryan, Bulloch, Chatham, Effingham, Liberty, and Glynn Counties.  This radio system is designed to provide communications for the I-16 and I-95 corridors from Statesboro area to the Brunswick area with more expansion in the future.  By monitoring this system, you’ll not only hear what is going on in Chatham County, but in surrounding counties as well.  Bryan County uses it as the primary communications system for their public safety agencies and Liberty County has recently begun using it as their primary communications system as well.  Frequency and talkgroup lists for SEGARRN can be found on the RadioReference SEGARRN page.  Some of the best SEGARRN talkgroups to keep an ear on during Hurricane response might be the NIMS (National Incident Management System) talkgroups.  Some of these talkgroups were recently used for St. Patrick’s Day in Savannah and in a recent HURREX (Hurricane Exercise).  The NIMS talkgroups on the SEGARRN also have equivalent talkgroups on the Chatham-Effingham System and are listed here in parentheses).

Both Hunter Army Airfield and Savannah International Airport and the military units based there would be involved in relief operations in the event of a hurricane striking the coastal Georgia area. B/1-169 Aviation of the Georgia Army National Guard at Hunter AAF would likely support local operations while the 165th Airlift Wing at Savannah IAP would be able to help provide an air bridge for the Savannah area. The United States Coast Guard would also assist in the response to a hurricane with both aircraft from Air Station Savannah and surface assets from Sector Charleston and its subordinate unit Station Tybee (and beyond).

Charleston Air Force Base is involved in relief operations not only nationwide but worldwide. Aircraft inbound to Charleston AFB from the south can easily be heard from the Savannah area.

Another agency that would support hurricane response efforts would the United States Air Force auxiliary, the Civil Air Patrol. The Civil Air Patrol is in the midst of frequency changes, so it would be prudent to keep both their old and new frequencies in mind. The CAP also uses repeater output frequencies as simplex frequencies.

148.150 – Civil Air Patrol Primary Repeater Output
148.125 – Civil Air Patrol Repeater, Coastal Georgia Area

148.175 – New Civil Air Patrol Repeaters
148.775 – New Civil Air Patrol Repeaters

There are many lists on the Internet that list HF frequencies for the “Hurricane Hunter” aircraft. For the most part, these lists are obsolete; the “Hurricane Hunters” now use satellite communications, including military SATCOM, instead of HF for their primary means of communications with ground stations.
