RAYNET - The Radio Amateurs' Emergency Network

The Radio Amateurs Emergency Network is the UK’s national voluntary communications service provided for the community by licensed radio amateurs. RAYNET was formed in 1953 following the severe East coast flooding, to provide a way of organising the valuable resource that Amateur Radio is able to provide to the community.

Since then, it has grown into a very active organisation with around 5000 members, providing communication assistance on many hundreds of events each year.
