Amateur radio emergency communication is a global capability. While programmes like ARES and RACES are specific to the United States, virtually every country with an active amateur radio community has some form of organized emergency communication capability. This page surveys the major international organizations, regional programmes, and the regulatory framework that enables amateur radio emergency communication worldwide.
The International Amateur Radio Union (IARU) is the worldwide federation of national amateur radio societies. The IARU plays a central role in coordinating emergency communication policy and practices at the international level.
The IARU maintains guidelines and recommendations for emergency communication that its member societies can adapt to their national contexts. Key IARU contributions include:
The IARU is organized into three regions that mirror the ITU regions:
Each region has its own emergency communication coordination and recommended practices.
The IARU recommends centre-of-activity frequencies for emergency communication on the HF bands. These are frequencies where operators should listen for emergency traffic and where initial contact can be established during international incidents:
| Band | Frequency | Mode |
|---|---|---|
| 80m | 3.760 MHz (Region 1), 3.985 MHz (Region 2) | SSB |
| 40m | 7.110 MHz (Region 1), 7.240 MHz (Region 2) | SSB |
| 20m | 14.300 MHz | SSB |
| 17m | 18.160 MHz | SSB |
| 15m | 21.360 MHz | SSB |
These frequencies are not exclusive to emergency traffic, but operators are expected to give priority to emergency communications on these channels.
The Radio Amateurs' Emergency Network (RAYNET) is the UK's primary amateur radio emergency communication organization, founded in 1953 following severe flooding along the east coast of England.
Structure: RAYNET is organized into local groups that align with county or regional boundaries. Groups are managed by local controllers and coordinate through regional and national leadership.
Relationship with authorities: RAYNET has established relationships with UK emergency services (police, fire, ambulance), the Environment Agency, local councils, and voluntary organizations like the British Red Cross and St John Ambulance. RAYNET does not self-deploy — it responds to requests from these served agencies.
Activities: RAYNET groups provide communication support for emergencies and public events. Regular activities include sponsored walks, marathons, cycle events, and agricultural shows, which serve as both public service and training opportunities.
Training: RAYNET operates its own training programme covering operational procedures, message handling, the UK emergency services structure, and deployment skills. Training is practical and focused on the UK operating environment.
Digital capabilities: RAYNET groups increasingly use digital modes alongside voice. Winlink and other data modes provide message handling capability.
Emergency communication in Canada is coordinated through several organizations:
RAC (Radio Amateurs of Canada): The national amateur radio society provides guidance on emergency communication and coordinates with Innovation, Science and Economic Development Canada (ISED), the federal regulator.
ARES Canada: Many Canadian provinces have ARES-style emergency communication groups, often coordinated through the RAC field organization. These groups follow organizational models similar to US ARES but adapted to Canadian emergency management structures.
CANWARN: The Canadian equivalent of SKYWARN, coordinating amateur radio severe weather spotters with Environment and Climate Change Canada.
Provincial coordination: Emergency management in Canada is primarily a provincial responsibility, and amateur radio emergency communication groups work with provincial emergency management organizations. Coordination varies by province.
The Wireless Institute Civil Emergency Network (WICEN) is Australia's primary amateur radio emergency communication organization, operating under the Wireless Institute of Australia (WIA).
Structure: WICEN is organized by state and territory, with groups in each jurisdiction. Each state WICEN group maintains relationships with state emergency services.
Relationship with authorities: WICEN works with state emergency services (SES), fire services, police, and other agencies. In several states, WICEN has formal agreements with emergency management agencies.
Activities: WICEN provides communication support for both emergencies and public events. Major Australian emergencies where WICEN has been active include bushfire seasons, cyclones, and flood events.
Challenges: Australia's vast geography and relatively sparse population in many areas make amateur radio particularly valuable for emergency communication in rural and remote regions. HF radio is often the only practical means of communication over the large distances involved.
The Japan Amateur Radio League (JARL) coordinates amateur radio emergency communication in Japan, a country that experiences frequent earthquakes, tsunamis, and typhoons.
History: Japan has one of the world's largest amateur radio communities, and JARL has a long history of supporting disaster response. The 1995 Great Hanshin earthquake (Kobe) and the 2011 Tōhoku earthquake and tsunami both demonstrated the critical role of amateur radio when other systems failed.
Structure: JARL organizes emergency communication through its regional structure. Local amateur radio clubs maintain emergency communication capabilities and coordinate with prefectural and municipal emergency management agencies.
Regulatory support: Japan's radio regulations include provisions for emergency amateur radio communication. Japanese authorities have recognized the value of amateur radio in disaster response, and the regulatory framework supports emergency use.
The Deutscher Amateur-Radio-Club (DARC) operates the Notfunk (emergency radio) programme in Germany.
Structure: DARC Notfunk is organized through district-level coordinators who work with local amateur radio groups. The programme maintains relationships with the Federal Agency for Technical Relief (Technisches Hilfswerk, THW) and other civil protection organizations.
Integration with civil protection: German amateur radio emergency communication operates within the broader Katastrophenschutz (disaster protection) framework. Amateur radio operators may be integrated into civil protection exercises and operations.
Digital emphasis: German Notfunk groups have placed strong emphasis on digital communication capabilities, including Winlink and other data modes.
Many European countries have established amateur radio emergency communication capabilities:
Amateur radio emergency communication is particularly valuable in developing countries and disaster-prone regions where commercial communication infrastructure may be limited or fragile:
The International Telecommunication Union's Radio Regulations include provisions relevant to amateur radio emergency communication:
During major international disasters, amateur radio operators may need to communicate across national borders. Several mechanisms support this:
HF (high frequency) radio is essential for international emergency communication because it can cover thousands of kilometres without any infrastructure. The 20-metre band (14 MHz) is the most commonly used for international emergency communication because it supports long-distance propagation during daylight hours across much of the world.
Winlink provides email capability over radio and is used internationally for emergency message traffic. The Winlink network includes radio mail servers (RMS) on multiple continents, supporting both HF and VHF/UHF access.
APRS operates internationally on 144.390 MHz in North America, 144.800 MHz in Europe, and other frequencies in other regions. It provides position tracking and short messaging capability.
SSB (Single Sideband) voice on HF remains the primary mode for real-time international emergency communication. FM voice on VHF/UHF is used for local and regional operations.
Amateur radio operators interested in international emergency communication can:
