"Introduction to Essex RAYNET"
Andy Atkinson
At the July Danbury meeting, Andy Atkinson M0IXY presented a nicely illustrated introduction and overview of Essex RAYNET.

As many will be aware the origins of the story go back to the East Coast Floods of 31st January 1953. This prompted the formation of the Radio Amateur Emergency Network in March 1954. In 2017 the independent and RSGB-affiliated groups came together and formed the RAYNET-UK national organisation, which provides administrative support to local groups, of which Essex RAYNET is in Zone-4

The current UK legal framework is the 2004 Civil Contingencies Act and is referenced in the Ofcom amateur licence along with the term 'User Services'.

Essex RAYNET has a role in the Essex Resilience Plan for providing emergency communications to Category 1 and 2 user services. In practice a more common request is to provide comms support for charities and communities events such as runs, cycling, car rallies, Clacton air show etc.

Currently Essex RAYNET has a membership of ~36 and assets across Essex including its own repeater network, use of APRS etc. There are also regular exercises with User Services including testing procedures and interoperability.

In concluding, Andy summarised some of the features of RAYNET activities:

Essex RAYNET

Supporting Communities Events such as the Farleigh Santa fun Run are good practice

Comms Support can involve significant planning and assets

Standardised Messaging is essential for User Service interoperability (no Q-Codes!)
