History


The Reason for RAYNET

Following a major disaster, public mobile, telephone and internet services will quickly become inundated or unusable. Telephone and mobile infrastructure may well be destroyed and in some cases power and water supplies may fail. Due to the Emergency Services now using the Mobile Network for their own communications and as they have priority over public users, this may render normal personal calls difficult or impossible.
Communications between communities, voluntary aid workers and relief services are vital for providing targeted relief of supplies including food, bedding, clothing, medical supplies or temporary accommodation. Help may also be required in organising any evacuation deemed necessary.
Radio Amateurs are ideally placed for such emergency communications. RAYNET’s aim is to set up and provide emergency links as quickly and efficiently as possible. We are able to provide communications from remote locations throughout Dumfries and Galloway including areas where no mobile signals are available. Our capabilities include communications on the HF, VHF and UHF radio bands, both analogue and digital. We can also provide temporary repeater systems to provide coverage of radio dead spots and we will erect temporary antenna systems when and where necessary. We have mobile power supplies and camping style accommodation that enables us to provide fully operational systems in remote locations for as long as required.

The History of Dumfries and Galloway RAYNET

Placeholder Picture

The history that led to the formation of  UK RAYNET goes back over 70 years, but RAYNET as it now stands, has its roots going back to 1953 and the devastating floods along the East coast of Britain.
Dumfries and Galloway Raynet was founded in 1986 by the late Alex Anderson GM4VIR after a major forest fire about 8 miles north of the town of Gatehouse of Fleet in 1982/3. The local WRVS were providing food and drinks from the village to the fire fighters but were having problems in updating the food requirements for the large number of people involved. Afterwards Mrs Lillian Dent the WRVS organiser asked Alex if the local amateurs could have provided some kind of radio link between the two and Alex decided then that Dumfries and Galloway Raynet should be established. The minutes of the first AGM dated 8th September 1986 show members present as John GM6LYJ, Alan GM4XTI, Keith GM4JKB, Sam GM4HTI, Jack GM3OXK, Alex GM4VIR, Drew GM6AWA, Jim GM4RJF, John GM8RSC, Hazel GM4VIS and Lorna GM6WJI. The minutes go on to relate election of office bearers, Alex was elected controller and so Dumfries and Galloway Raynet began. Over the years the group has been very active in all parts of the region and were among the first Raynet groups on the scene at the Lockerbie air disaster along with operators from Strathclyde, Ayrshire and many other areas. Alex was awarded the MBE for his work during the disaster, which he accepted on behalf of all the Raynet operators involved.
Since then the group has been providing radio safety communications for all manner of events, including Sled Dog racing, Car Rallies, Marathon hill walks, Sealed Knot events, Endurance Horse Events, Mountain Bike Events, to name but a few.  The biggest event been the Galloway Hills Rally held in early December. This event often required up to 35 operators located at varios points throughout the Galloway Forest. Multiple talk through units were provided to cover the entire area of rally.

Flooding Callout 30th December 2015

Dumfries and Galloway RAYNET were mobilised by D&G Council on the 30th of December to provide emergency radio communications from Newton Stewart to Dumfries for their community resilience teams. BT had closed down their local exchange due to flooding of unprecedented levels. This led to a complete loss of fixed and mobile telephones and internet services around Newton Stewart isolating all in the Town but the Police, Fire, Ambulance and MRT from any form of voice and data communication with the rest of Dumfries and Galloway.
We received the call at approximately 16:00 Hrs and within 90 minutes we had a team of three at the rest centre in Newton Stewart and three members at the Dumfries Emergency Planning Bunker radio room, providing a solid radio link between the two locations via our local repeater GB3DG.
We were stood down at approximately 20:00 Hrs when the waters began receding and the BT exchange was more or less up and running again, with fixed and mobile phones back in service although internet was not restored for some time.
