SARG Repeaters


We serve the local Amateur radio users with a method of communication over long distances, using low power radios with the repeater relaying over a wider area. 

Our Repeaters are for licensed radio amateurs to communicate as part of the hobby of amateur radio. Please give priority to mobile users or emergency traffic.

Use of ANY of the Repeaters within our Group for operational, community or planned RAYNET events is at the discretion of the Repeater Keeper only – including all Club Nets.

An EGM to follow up on the poorly attended AGM on 12th May was held on Tuesday 9th July 2024 at 7pm start at Wetheringsett Village Hall. 8 people attended with four apologies.

Minutes of the EGM and the constitution with the amendments approved at the EGM can be downloaded below. The Committee for 2024-2025 is

Secretary: Iain Moffat G0OZS

Treasurer: Mark Austin M1NIZ

The group would like to thank Keith Gaunt G7CIY for his work as Keeper of GB3PO and GB3IH over the past 20 years and Jake Bevan G1YFF for his work as keeper of GB3EA and GB3EZ until their relocation in 2024.

It was agreed after the formal EGM to upgrade the GB3IH hardware to be capable of 12.5KHz channels and seek a frequency change to 9MHz split so leaving behind QRM from low power devices in the 433-434MHz range.
