The Radio Amateurs’ Emergency Network Using the wide range of radio bands, operating modes and equipment available to Amateur Radio operators and the seemingly limitless resourcefulness of the Club’s members, the Northampton Radio Club’s branch of RAYNET offers a unique range of emergency communication services to our user services. RAYNET is regarded as a professional support organisation by both the statutory and volunteer emergency service organisations. For more information, visit http://www.raynet-uk.net/ Our frequent attendance at a variety of large, outdoor sporting events and providing communications services to the event organisers, facilitates the training which prepares our group to implement emergency communications networks in case of a major civil emergency. From the technical perspective, much work has already been done by Dr. Peter Best G8CQH at Aston University in forming a standard for the connection between two-way radio transceivers and the various forms of microphone, loudspeaker, headphone or headset accessory which an operator may employ for vocal telecommunications. This allows the operator to select the most appropriate accessory for a particular communications need, and operate any available and appropriate transceiver to provide a communications service in a wide variety of circumstances. Implementation of common standards such as CAIRO reduce the time taken to construct communications networks, increase the interoperability of equipment and groups that need to work together in emergency situations.
