United States Coast Guard Auxiliary

 "Where The Action Is!"

There is no requirement in the Auxiliary to obtain a ham license; auxiliarists can merely take the AUXCOM course, or the same communications watchstander PQS that the gold side active duty coast guard requires of it's communicators, or the new auxiliary telecommunications operator course that was just announced. (And may eventually replace the first two.) Additionally, boat crew and aircrew can use the radio equipment on those facilities without any additional certification.

But auxiliarists who fit the above criteria can communicate on both Coast Guard frequencies and the numerous additional ham frequencies if they get licensed to do so. And being able to talk to an additional set of emergency service, trained and dedicated volunteers is invaluable. We appreciated all the help we could get in Katrina, and need to train with all available resources we can use or potentially could use, during the next disaster.

Why Hams?   Where do Ham Operators fit into the emergency services provided by the Auxiliary and the Coast Guard?

Ham operators are internationally recognized as good communicators. They have developed skills sets, in both every day radio communications, as well as emergency communications, through such organizations as Radio Amateur Civil Emergency Service (RACES), the Amateur Radio Emergency Service (ARES) and the National Weather Services (NWS)' SKYWARN.

The Amateur Radio Operators who volunteer for these services train and practice their skills in drills, waiting for that one event which may never come, to put their skill set into action.   The Auxiliary is always interested in individuals with unique skill sets.  Amateur Radio Operators are among these types of individuals.

Remember ? Auxiliary communications specialists practice their skills every day, in the real world.  Whether it?s doing a Maritime Domain Awareness (MDA) patrol via vehicle, and needing two-way communications with the Active Duty Coast Guard, a Safety Patrol on the water, augmenting the communications watch at an active duty Coast Guard unit, or even assisting at major events, these types of events are daily on-going Auxiliary missions, in every part of the US.

Communication and good communicators are at the heart of any successful mission, and Ham Operators have the experience that the Auxiliary is both looking for and would like to instill in their current communicators.

Qualified Ham Operators can become instructors, teaching non-Ham operators the techniques and skills that will make them skilled radio operators.

Auxiliary members provide important operational support to the U.S. Coast Guard and are considered members of "Team Coast Guard." Patrols are often called upon for search and rescue assistance, Helo Ops co-ordination drills, and other training missions. In addition, special patrols may check navigational markers, update charts, or monitor the waters for hazards and environmental pollution. Division 4 takes on as much as it can reliably handle, making Active Duty assets and resources available for other uses, or available to "standby for surge" operations when necessary.

During Katrina all telecommunication towers, including both public safety and amateur repeaters went down. It was a radio amateur of the Coast Guard Auxiliary that "re-discovered" the old technique of NVIS. The Coast Guard took an extreme interest in NVIS. Being a bureaucracy, they can't just go out, buy the right equip, and start using it. (studies have to be done; security protocols ensured, etc) But the auxiliary can. They can then use the aux to communicate on it when they themselves can't. (click here for a FAQ on NVIS)

In times of crisis and natural disasters, Amateur radio is often used as a means of emergency communication when wireline, cell phones and other conventional means of communications fail.

Unlike commercial systems, Amateur radio is not as dependent on terrestrial facilities that can fail. It is dispersed throughout a community without "choke points" such as cellular telephone sites that can be overloaded.

Amateur radio operators are experienced in improvising antennas and power sources and most equipment today can be powered by an automobile battery. Annual "Field Days" are held in many countries to practice these emergency improvisational skills. Amateur radio operators can use hundreds of frequencies and can quickly establish networks tying disparate agencies together to enhance interoperability.

Recent examples include the 2001 attacks on the World Trade Center in Manhattan, the 2003 North America blackout and Hurricane Katrina in September, 2005, where amateur radio was used to coordinate disaster relief activities when other systems failed.

On September 2, 2004, ham radio was used to inform weather forecasters with information on Hurricane Frances live from the Bahamas. On December 26, 2004, an earthquake and resulting tsunami across the Indian Ocean wiped out all communications with the Andaman Islands, except for a DX-pedition that provided a means to coordinate relief efforts.

The largest disaster response by U.S. amateur radio operators was during Hurricane Katrina which first made landfall as a Category 1 hurricane just north of Miami, Florida on August 25, 2005, eventually strengthening to Category 5. More than a thousand ham operators from all over the U.S. converged on the Gulf Coast in an effort to provide emergency communications assistance. Subsequent Congressional hearings highlighted the Amateur Radio response as one of the few examples of what went right in the disaster relief effort.

In the United States, there are two major methods of organizing amateur radio emergency communications: Amateur Radio Emergency Service (ARES), sponsored by the ARRL, and the Radio Amateur Civil Emergency Service (RACES), which requires registration with municipal or county governments, to allow continued operation under Part 97.407 of the FCC regulations in the event the Amateur Service is ever shut down by presidential order. ARES and RACES involvement within the same area are usually intertwined, with many governments requiring membership and service in that locale's ARES organization as well. Many government Emergency Operating Centers, Red Cross Chapters and National Weather Service facilities have permanent Amateur Radio stations installed.

Radio clubs independent of the ARRL and ARES also participate in emergency communications activities in some areas. Additionally, the Department of Defense also sponsors the Military Affiliate Radio System (MARS) program which also utilizes Amateur Radio operators for emergency communication using military radio frequencies.

Emergency communications and disaster assistance is usually done in conjunction with volunteer disaster relief organizations such as the American Red Cross, Civil Air Patrol (aux of the USAF - SAR command), Coast Guard Auxiliary, or local government emergency management agencies, as well as volunteer fire departments and ambulance corps.

The ARRL has a memorandum of understanding with numerous agencies such as the American Red Cross. The ARRL also is a member of the Voluntary Organizations Active in Disasters (VOAD) and conducts emergency communications certifcation courses for interested Amateur Radio operators.


This site supports the VoIP SKYWARN and Hurricane Nets which they operate by combining both the Echolink and IRLP linked repeater networks, thus providing for more efficient and effective utilization of available resources while handling critical wide area communications during major severe weather events. To learn more about the efforts of the VoIP Hurricane Net, join the VOIP-WXNET Yahoo Group to keep informed and learn more about the use of EchoLink and IRLP for hurricanes and other weather and disaster related situations.

The VoIP Hurricane Net wants ARES, RACES, SKYWARN and other emergency communication groups such as MARS and REACT to utilize the VoIP Hurricane Net as another means to pass weather data, damage and other pertinent reports to WX4NHC--the Amateur Radio station at the National Hurricane Center (NHC) in Miami--and to other national agencies. During hurricanes, NHC forecasters use real-time "ground truth" reports from Amateur Radio volunteers--such as the Hurricane Watch Net (HWN) on 14.325 MHz--to the NHC via WX4NHC to develop more accurate forecasts and to get a better handle on a storm's behavior.

The ALE High Frequency Network (HFN) is available 24/7 for emcomm text messaging. HFN provides HF-to-email, HF-to-cellphone, and HF-to-HF messaging relay.  Amateur Radio for Broadband wireless internet here.  Interactive Map of Amateur radio repeaters here.
