GB3VHF & GB3UHF - beacons designed for the 21st Century

Welcome to, the website of the 144.430 MHz and 432.430 MHz amateur radio beacons located at BT Fairseat on the North Downs in Kent (JO01EH). Providing a service to amateur radio operators on two metres for over sixty years and now also on 70 cms.

The beacons continue to provide a service to amateur radio and professionals alike, for the study of long distance VHF and UHF propagation, equipment and antenna system performance evaluation and checking, and scientific studies, for those located both in the UK and internationally.

The Fairseat site at a height of 205m ASL is located approximately 10 kms south of Gravesend or 2 kms north east of Wrotham village, and has a clear take off in all directions.

The beacons are independently run “for VHF/UHF DX-ers, by VHF/UHF DX-ers” and receive no financial support from any organisation. Please also consider donating towards ongoing costs by going to the Donate to the beacon fund page. All donations will be greatly appreciated and will be acknowledged.

Please have a look around the website and read about the beacon’s advanced technical features and facilities, and the story of GB3VHF which is one of the longest serving amateur radio beacons in the world and also details of the GB3UHF beacon on 432.430 MHz.

The support given to the Fairseat beacons project by BT Radio engineering staff and BT Wholesale staff is much very much appreciated and acknowledged - thank you.

I have been the GB3VHF beacon keeper for some eighteen years now, and previous to that I was involved to a high degree with the maintenance of the GB3VHF beacon for several years. During that time I have endeavoured to make sure that the service to radio amateurs continues as it has successfully done for the past sixty years. I hope that you will enjoy and make good use of the GB3UHF beacon which completes the dual beacon pair propagation project.

Thanks very much for your continued support

Good DX and regards
