United Kingdom

In the United Kingdom Radio Amateurs Emergency Network (RAYNET) provides the organizational backbone of their amateur radio emergency communications groups along with the Radio Society of Great Britain (RSGB). It was formed in 1953 in the aftermath of the North Sea flood of that year.

United States of America

In the United States, there are two major methods of organizing amateur radio emergency communications: the Amateur Radio Emergency Service (ARES), an organization of amateur operators sponsored by the American Radio Relay League (ARRL); and the Radio Amateur Civil Emergency Service (RACES), a standby replacement radio service regulated by the Federal Communications Commission. Operations under the RACES rules requires preregistration with a local civil defense organization, to allow continued operation under Part 97.407 of the FCC regulations in the event the Amateur Radio Service is ever shut down by presidential order. Thus ARES and RACES involvement within the same area are usually intertwined, with many governments requiring membership and service in that locale's ARES organization to allow operations within the Amateur Radio Service as well. Many government Emergency Operations Centers, Red Cross Chapters and National Weather Service facilities have permanent Amateur Radio stations installed for such operations.

The ARRL provides extensive documentation on how to conduct emergency radio communications, including its Public Service Communications Manual.

Radio clubs independent of the ARRL and ARES also participate in emergency communications activities in some areas, and some non-radio organizations have their own amateur arm. The Department of Defense sponsors the Military Auxiliary Radio System(MARS) program which utilizes Amateur Radio operators for emergency communication using military radio frequencies. The National Weather Service Skywarn weather-spotter program has a strong amateur radio contingent. And amateurs dedicated to the Salvation Army are organized under their Salvation Army Team Emergency Radio Network program.

Emergency communications and disaster assistance is usually done in conjunction with volunteer disaster relief organizations such as the American Red Cross, the Salvation Army, local government emergency management agencies, as well as volunteer fire departments and ambulance corps.

The ARRL has memoranda of understanding with numerous agencies expected to receive services,^[9] including the American Red Cross and Salvation Army and is a partner in the Citizen Corps program of the Federal Emergency Management Agency (FEMA). The ARRL also is a member of the National Voluntary Organizations Active in Disaster (NVOAD) and conducts emergency communications certification courses for interested Amateur Radio operators.

Canada

In Canada, Amateur Radio Emergency Service (ARES) is sponsored by the Radio Amateurs of Canada. Often other less formal networks of volunteer radio operators are also used and organized by the local emergency response agencies in conjunction with local ham radio operators. As in the United States, Radio Amateurs of Canada has memoranda of understanding with numerous agencies expected to receive services[2], including the Canadian Red Cross and Salvation Army.

  Thank you Yusuf for having organized this workshop enabled me to understand winlink.

  
  

  Will be trying this week to tx an email via Vhf?

  
  

  Antenna parameters were also compared and simple wire antennas seem best for emcom, even for portable NVIS comms.....
