What does ARES do?
ARES, the Amateur Radio Emergency Service, is the American Radio Relay League's (ARRL) volunteer emergency service in the United States. Licensed hams register their skills and equipment with a local Emergency Coordinator, then take communications duty when a disaster strikes. ARRL membership is not required.1
Only licensed amateurs can join, because ARES is an amateur service.12 The ARRL counted 31,332 ARES members in 2017, up nearly 13 percent on 2016.3
ARES follows the ARRL's sections. Each level has a coordinator:2
| Level | Role |
|---|---|
| Section | The Section Emergency Coordinator (SEC) works under the elected Section Manager |
| District | The District Emergency Coordinator (DEC) leads local coordinators in large sections |
| Local | The Emergency Coordinator (EC) runs ARES for one town, city or county |
In 2019 the ARRL Board adopted an ARES Plan and a standard training plan.4 The task book is at version 3.0 as of July 2024 and has three levels:5
- Level 1, Basic. Join a local ARES group, hold a Technician license or higher, and take a basic course plus the Federal Emergency Management Agency (FEMA) courses IS-100 and IS-700.
- Level 2, Intermediate. Adds IS-200 and IS-800, a net each quarter, and writing and sending an ICS-213 message, a form from the Incident Command System.6 The book says this level meets the minimum for deployment.
- Level 3, Advanced. The leadership path, including running nets.
How is RACES different from ARES?
RACES, the Radio Amateur Civil Emergency Service, is a part of the US amateur service for civil-defense communications, run by government emergency-management agencies. ARES is run by the ARRL and works for served agencies in any emergency. They are separate, and many hams join both.72
| ARES | RACES | |
|---|---|---|
| Who runs it | The ARRL2 | Local, county and state emergency-management agencies, supported by FEMA2 |
| Who can join | Any licensed amateur1 | An FCC-licensed station certified by a civil-defense organization7 |
| When it acts | In any emergency, for served agencies2 | Only on traffic the civil-defense organization has authorized7 |
| Drills | Including the Simulated Emergency Test5 | Up to 1 hour a week in total7 |
With approval of the state's chief emergency-planning officer, RACES drills can run up to 72 hours, no more than twice a calendar year.7 While operating as RACES, a station cannot talk to amateurs who are not in RACES.2
The ARRL recommends dual membership. A group enrolled in both can "switch hats" without changing people or frequencies, for example from ARES in an ordinary emergency to RACES once authorities declare one.2
How do hams pass messages in a disaster?
Hams pass written messages, called radiograms, through the ARRL's National Traffic System (NTS). Trained volunteers hand messages on through daily nets, which are scheduled on-air meetings of stations, at local, section, region and area level. Each radiogram carries a precedence: Emergency, Priority, Welfare or Routine.89
The National Traffic Plan was announced in QST in September 1949.10 The ARRL says much traffic is now between hams, and that phones, text and the internet give the public other options.8
| Precedence | Meaning |
|---|---|
| Emergency | Always spelled out. Life-and-death traffic when normal channels are unavailable |
| Priority (P) | Handled after Emergency and before Welfare |
| Welfare (W) | Inquiries about, or all-clear reports from, a disaster area |
| Routine (R) | Handled last in disasters |
The goal for Emergency traffic is 30 minutes from end to end.11
A radiogram has a preamble, an address, the text and a signature.12 The "check" in the preamble is the number of word groups in the text. The receiver counts them and compares.12 Prowords and the phonetic alphabet used on air are listed under radio codes. To write one and see how it is read on air, try the radiogram builder: it counts the check for you.
What is Winlink?
Winlink is a worldwide email system that runs over radio. Users connect to gateway stations, which pass messages on to ordinary internet email. It can also work station to station without the internet. Licensed volunteers build, run and administer it.13
The Amateur Radio Safety Foundation, Inc. (ARSFI), a US nonprofit, operates it.13 It is one of the digital modes described in What is ham radio?.
After Hurricane Maria in 2017, the first aim of the ARRL teams in Puerto Rico was to move health-and-welfare messages to the Red Cross "Safe and Well" system by Winlink.14 In Hurricane Helene's recovery in 2024, the ARRL said Winlink "has been used significantly". Its emergency-management director said the 2023 FCC removal of symbol-rate limits let hams use it at once without a waiver.15
It has limits. An older ARRL Eastern Massachusetts page calls Winlink good for routine and welfare messages to known email addresses, and not for emergency or priority traffic unless the receiver is also told by voice.16
Which frequencies are used for emergencies?
The International Amateur Radio Union (IARU) lists emergency "centers of activity" on five bands. 14.300, 18.160 and 21.360 MHz are the same in all three IARU regions. The 80 m and 40 m choices differ by region. Emergency traffic may be found within 20 kHz of each.17
Emergency frequencies where you are
- 80 m3.76 MHz
- 40 m7.11 MHz
- 20 m14.3 MHz
- 17 m18.16 MHz
- 15 m21.36 MHz
| Band | Region 1 (MHz) | Region 2 (MHz) | Region 3 (MHz) |
|---|---|---|---|
| 80 m | 3.760 | 3.750 or 3.985 | 3.600 |
| 40 m | 7.110 | 7.060, 7.240 or 7.275 | 7.110 |
| 20 m | 14.300 | 14.300 | 14.300 |
| 17 m | 18.160 | 18.160 | 18.160 |
| 15 m | 21.360 | 21.360 | 21.360 |
Region 1 covers Europe, Africa, the Middle East and the former Soviet states. Region 2 is the Americas. Region 3 is Asia and Oceania.18
These are centers of activity, not exact channels, and some countries keep their own emergency frequencies.17 Real events use their own channels. After the 2023 Türkiye earthquake, 28.540 MHz (upper sideband) was the main frequency.19
The Hurricane Watch Net activates when a storm at hurricane strength is within about 300 statute miles of populated land. It uses 14.325 MHz (upper sideband) by day and 7.268 MHz (lower sideband) at night, and works with WX4NHC, the amateur station at the National Hurricane Center in Miami.20
Much local work happens on VHF and UHF instead. The IARU says local VHF and UHF networks keep working when commercial links fail or are overloaded.21 Band reach is in What is ham radio? and the two-way radio range guide.
Is there ARES in Europe?
Not under that name. ARES is the ARRL's service, so groups elsewhere use their own names: RAYNET in the UK, Notfunk in Germany and Austria, REMER in Spain, DARES in the Netherlands. Most are run by national amateur radio societies, a few by civil-protection authorities.12223242526
| Country | Group | Who runs it | What it does |
|---|---|---|---|
| United Kingdom | RAYNET (Radio Amateurs' Emergency Network) | National charity of local groups, affiliated with the Radio Society of Great Britain (RSGB)27 | Back-up communications for floods, searches and event safety cover22 |
| Germany | DARC Notfunk | DARC e.V., the German amateur radio club23 | Emergency radio with local clubs and authorities23 |
| Austria | ÖVSV Notfunk (A.R.E.N.A.) | ÖVSV, the Austrian amateur radio association24 | Mains-independent stations for outages, monthly on-air drills24 |
| France | FNRASEC and the ADRASEC groups | The federation FNRASEC28 | Back-up networks, direction-finding of aircraft distress beacons28 |
| Italy | ARI-RE, the "Rete Zamberletti" | ARI, the Italian amateur radio association29 | Emergency network linking amateurs to the Interior Ministry and prefectures29 |
| Spain | REMER | Civil Protection, Ministry of the Interior25 | Back-up for Civil Protection's own networks25 |
| Netherlands | DARES | Stichting DARES, a foundation26 | Volunteer back-up when official systems fail26 |
RAYNET in the UK
RAYNET grew out of the North Sea storm flood of early 1953. Its FAQ and the RSGB date it to 1953, while its history page says 1954.223027 Anyone aged 14 or over can join through a local group. No amateur license is needed, and the national fee is £12 a year, which some groups pay.31
The UK amateur license (Ofcom OFW611) lets the licensee use or permit use of the equipment to assist communications in times of disaster or emergency. A "user service" such as the British Red Cross or St John Ambulance may use it in an operation run by a "Responder". The license does not name RAYNET.32
Notfunk in Germany and Austria
"Notfunk" is German for emergency radio. The DARC has a unit for emergency and disaster radio (Not- und Katastrophenfunk).23 Some DARC repeaters receive the federal warning feed used by the NINA app.23 A 2018 ÖVSV talk said hams are not an "Einsatzorganization", a formal emergency service with a hierarchy.33
The Ahr valley flood of July 2021 has more than one account. IARU Region 1 reported that the DARC emergency unit handled requests for radio support in the worst-hit areas.34 DARC's own 2022 slides say amateurs were not requested in the Ahr valley, and DARC chose to act even without being asked.35 Hessen's interior minister says hams gave practical help.36 Taken together, hams were active in 2021 but not part of the official response.3536
REMER in Spain
REMER, the Red Nacional de Radio de Emergencia, is a state network of volunteer hams under Civil Protection. A Civil Protection resolution created it on 1 December 1986, and Orden INT/1149/2018 of 29 October 2018 now regulates it. Applicants must be adults living in Spain, hold a valid amateur license and be authorized by the Directorate.25 The club URE runs a separate emergency office, EMCOM España.37
Outside Europe
| Country | Group | What it does |
|---|---|---|
| Canada | RAC Auxiliary Communications Service (ACS), formerly RAC ARES | Takes over the original function of RAC ARES: certified communicators for local emergency-management groups38 |
| Australia | WICEN (Wireless Institute Civil Emergency Network) | Communications for emergency services where infrastructure has failed or is absent39 |
| New Zealand | AREC (Amateur Radio Emergency Communications) | Search and rescue and civil defense radio; about 300 trained volunteers40 |
| Japan | JARL emergency activity | In March 2011 the headquarters station JA1RL acted as an emergency traffic center41 |
When has ham radio helped?
Hams have supported relief work from Japan in 2011 to Hurricane Helene in 2024. They carry welfare messages, link shelters and agencies, and pass reports when other links are down or overloaded. Their role depends on the event and on who asks for them.411542
| Year | Event | What hams did |
|---|---|---|
| 2011 | Japan earthquake | JARL station JA1RL handled emergency traffic on 7.030 MHz and VHF/UHF; local hams set up stations at shelters41 |
| 2015 | Nepal earthquake | Hams ran HF and local nets, travelled with relief teams and sent welfare messages and SSTV pictures43 |
| 2017 | Hurricane Maria, Puerto Rico | At the Red Cross's request, about 50 hams answered within 24 hours. 22 deployed for about three weeks, then 10 SHARES HF operators replaced them1444 |
| 2021 | Western Europe floods | DARES stood by, a Belgian B-EARS back-up VHF link connected Brussels and Hainaut province, and the DARC handled support requests34 |
| 2023 | Türkiye and Syria earthquakes | TRAC coordinated amateur emergency communications. Hams could help search teams only when attached to accredited rescue teams1942 |
| 2024 | Hurricane Helene, US Southeast | Hurricane Watch Net and WX4NHC reports before landfall; ARES volunteers in county offices and the Florida emergency operations center15 |
The Maria request was the first of its kind in about 75 years of the Red Cross and ARRL relationship.14 For Helene, the ARRL wrote that radio was the only means of passing information for several days.15
Why not just use phones or TETRA?
Professional responders use networks built for them: TETRA (Terrestrial Trunked Radio) in Germany, 4G-based networks in the UK and a dedicated broadband network in the US. They are strong systems, but they run through base stations and network cores. Ham radio works radio to radio.454647
| System | Where | Key facts |
|---|---|---|
| BOS Digitalfunk (TETRA) | Germany | More than 5,000 base stations, about 99.2 percent area coverage, about 1.3 million terminals45 |
| Emergency Services Network (ESN) | United Kingdom | Replaces the Airwave radio system with a 4G-based network; Airwave extended to December 20294648 |
| FirstNet | United States | Dedicated nationwide broadband network on Band 14, with priority access and pre-emption47 |
Hessen's interior ministry says the German network is hardened to keep working at least 72 hours without mains power.36 The IARU says low-power HF gear with a car battery and a simple wire antenna can work from almost anywhere.21 ÖVSV adds that each ham station works on its own and hams can bridge different radio systems.33 But ham voice is unencrypted, which limits its place in official channels.36
Push-to-talk over cellular (PoC) belongs to the network family: like the 4G responder networks, it needs a mobile connection. See What is a PoC radio?, TETRA and public-safety radio.
What goes in a go-kit?
The ARRL's guidance from September 2024 is to pack two kits: one for personal needs and one for radio needs. The personal kit holds several days of food and water, a first-aid kit, medications and chargers. The radio kit holds a dual-band handheld or mobile radio with its antenna, power supply and cables.49
- Radio. Add paper and pens. For HF add a radio and antenna. For digital modes add a computer with software preloaded.49
- Extras. Tape, tools, spare batteries, headphones, a flashlight, phone chargers and a multimeter.49
How do you join?
Get a license, find your local coordinator or group, register, train, and join nets and drills. In the US you join ARES through the local Emergency Coordinator. In the UK you join RAYNET through a local group, and no license is needed. The steps are below.131
- Get a license. In the US, Technician or higher is the ARES baseline.5 You need a ham license, and you can test yourself first.
- Find your group. Use ARRL's "ARES by Section" resource, or the Contact page on RAYNET-UK.131
- Register. Give the ARES Registration form to the EC. For RAYNET, register with the group, which sends the application to RAYNET-UK.131
- Train. Take the free EC-001 course, IS-100 and IS-700, and keep a task book.45
- Join nets and drills. Take part in nets, the Simulated Emergency Test and public-service events. Consider SKYWARN, the National Weather Service's storm-spotter program.550
Once licensed, you get a call sign: see What is a ham radio call sign?.
Questions
Do I need a license to join ARES?
Yes. Only licensed amateurs are eligible, because ARES is an amateur service. The task book sets a Technician license or higher as the baseline, and local groups may require training. ARRL membership is not required. You register on a form given to your local Emergency Coordinator.15
Is ARES part of the ARRL?
Yes. ARES is the ARRL's service, with ARRL Headquarters at the national level, a Section Emergency Coordinator in each section and a local Emergency Coordinator for each town or county. The name is an ARRL mark, so groups in other countries use their own names.12
What may a ham do in an emergency that the rules normally forbid?
In the US, rule 97.403 says nothing in Part 97 stops an amateur station from using any means of radio communication it has to meet essential needs for the immediate safety of life and property, when normal systems are unavailable. The UK license lets hams assist communications in a disaster or emergency.5132
What is 14.300 MHz?
It is the IARU emergency center of activity on 20 m, the same in all three regions. Emergency traffic may be found within 20 kHz of it. In North America the Hurricane Watch Net uses 14.325 MHz by day instead.1720
Is RAYNET the same as ARES?
No. RAYNET is a UK national charity of local groups that anyone aged 14 or over can join without a license. ARES is the ARRL's US service, open only to licensed amateurs. Both are volunteer emergency radio services, but they are separate organizations in different countries.27311
