provision of emergency communications is one of the fastest growing areas of amateur radio around the world.</p> <p>Amateur radio is so useful to emergency communications because it does not depend on any infrastructure.</p> <p>That means amateur radio does not rely on the electrical power grid or any cabled network.</p> <p>Although mobile phones and the internet have wireless capability, they are still dependent on fixed masts and cabling which can be severely disrupted by a natural or man-made disaster; so while very useful in an emergency, mobiles and the internet cannot be relied upon completely.</p> <p>When the phone lines are down and the electricity is off, it is still possible to communicate worldwide with amateur radio using only battery power.</p> <p>This versatility has saved many lives over decades of amateur radio emergency service.</p> <p>Amateur radio still gets through when everything else has failed.</p> <h3>RAYNET</h3> <p>RAYNET was formed in 1953 following the East Coast floods, when radio amateurs provided emergency communications, and was administered by the RSGB.</p> <p>Radio Amateurs who are willing to provide communications during emergencies are organised in autonomous local RAYNET Groups and are also members of the national organisation, RAYNET-UK.</p> <p>There are over 100 RAYNET Groups around the country. These Groups practice and improve their skills by taking part in exercises or by providing communications for community events.</p> <p>RAYNET-UK is a registered charity, affiliated to the RSGB and there is regular liaison between the two, promoting a coordinated approach to emergency communications.</p> <p>RAYNET-UK provides the special support which Groups need, such as specific insurance and photo ID. RAYNET-UK also liaises with the emergency services, government and other organisations at a national level. Only groups in RAYNET-UK are able to use the title RAYNET.</p> <p>Many RAYNET groups are affiliated to the RSGB as Clubs.</p> <p>FIND OUT MORE: Visit the <strong><a href="http://www.raynet-uk.net/">RAYNET-UK website</a></strong></p> <p> </p> <div style="clear:both;"></div> </div> </div> </div>  </div>  <div id="contentright"> <div id="sidebar" class="clearfix"> <div id="hierpage-2" class="widget widget_hier_page"><div class="widget-wrap"><h3 class="widgettitle"><span>In this section</span></h3><ul><li class="page_item page-item-14 page_item_has_children current_page_ancestor current_page_parent"><a href="https://rsgb.org/main/operating/">Operating</a> <ul class='children'> <li class="page_item page-item-8360"><a href="https://rsgb.org/main/operating/operating-guidelines/">Operating Guidelines</a></li> <li class="page_item page-item-23047"><a href="https://rsgb.org/main/operating/dx-code-of-conduct/">DX Code of Conduct</a></li> <li class="page_item page-item-20523"><a href="https://rsgb.org/main/operating/operating-advisory-service/">Operating Advisory Service</a></li> <li class="page_item page-item-384"><a href="https://rsgb.org/main/operating/amateur-radio-awards/">Awards</a></li> <li class="page_item page-item-651"><a href="https://rsgb.org/main/operating/band-plans/">Band Plans and information</a></li> <li class="page_item page-item-5844"><a href="https://rsgb.org/main/operating/beacons-and-repeaters/">Beacons & Repeaters</a></li> <li class="page_item page-item-332 page_item_has_children current_page_item"><a href="https://rsgb.org/main/operating/emergency-communications/" aria-current="page">Emergency communications</a> <ul class='children'> <li class="page_item page-item-340"><a href="https://rsgb.org/main/operating/emergency-communications/raynet-id-cards/">RAYNET ID cards</a></li> <li class="page_item page-item-336"><a href="https://rsgb.org/main/operating/emergency-communications/rsgb-affiliated-emergency-groups/">RSGB affiliated emergency groups</a></li> </ul> </li> <li class="page_item page-item-1817"><a href="https://rsgb.org/main/operating/hf-dxpedition-fund/">HF DXpedition Fund</a></li> <li class="page_item page-item-737"><a href="https://rsgb.org/main/operating/licensing-novs-visitors/">Licensing, NoVs & Visitors</a></li> <li class="page_item page-item-5764"><a href="https://rsgb.org/main/operating/dx-cluster/">Live DX Cluster</a></li> <li class="page_item page-item-6223"><a href="https://rsgb.org/main/operating/live-solar-data/">Live solar data</a></li> <li class="page_item page-item-381"><a href="https://rsgb.org/main/operating/morse/">Morse</a></li> <li class="page_item page-item-741"><a href="https://rsgb.org/main/operating/planning-matters/">Planning matters</a></li> <li class="page_item page-item-659"><a href="https://rsgb.org/main/operating/qsl-bureau/">QSL Bureau</a></li> <li class="page_item page-item-6629"><a href="https://rsgb.org/main/operating/propagation-predictions/">Propagation predictions</a></li> <li class="page_item page-item-16389"><a href="https://rsgb.org/main/operating/web-sdr-receiver/">WebSDR receivers</a></li> </ul> </li> </ul></div></div><div id="ai_widget-2" class="widget ai_widget"><div class="widget-wrap"><div class='code-block code-block-1 ai-track' data-ai='WzEsIiIsIkJsb2NrIDEiLCIiLDFd' style='margin: 8px 0;
