THE FRYS HILL REPEATER GROUP WELCOMES YOU
ABOUT THE FRYS HILL REPEATER GROUP
A Bit of History...
The Frys Hill Repeater Group was formed in 2004, when we were granted permission to site and operate a 50MHz repeater (GB3FH) on a commercial site near Cheddar, Somerset. Permission was also granted at the same time for GB3CH to be moved from its existing site that was being shut down, over to a different mast at Caradon Hill in Cornwall. Some years before this CH had been moved off the Arqiva site where it had been since 1977, due to high site rental fees.
Soon after, some 70cm equipment became available and so GB3FI was added to the site, to benefit hand portable users.
Then in 2008, an opportunity arose to access a prime radio site on Dundry near Bristol and a 50MHz (GB3ZY) and 70cm (GB3ZB) repeater were sited here too, with the support of the owner of the site.
In 2015 I was approached to see if I could host a DMR repeater at Frys Hill and this was added to the network later that year (GB7FI) and in 2018 another DMR repeater (GB7BD) was added to the Bristol site. The resources of the Group are used to support all of these repeaters.
In addition, Matt, G4RKY who is the keeper of the Group's repeaters, also looks after GB3WR on the Mendips and GB3CH, GB3JL, and GB7LK located at Caradon Hill in Cornwall that are run by other repeater groups.
The Frys Hill Group is driven by a single goal; to give something back to the hobby of Amateur Radio that has helped us all so much over the years.
The Group is run by Matt G4RKY, Brian G4UTM & Ross G4YQY.
WHAT WE DO
PROVIDE RELIABLE AND HIGH PERFORMANCE RADIO COMMUNICATION SYSTEMS
Enabling Amateur Radio
With the Groups primary function always in mind, we strive to improve our systems to make them reliable and dependable. This is something that we take very seriously, and our team works hard to minimise outages and downtime by using good engineering practices and the best equipment wherever possible.
SUPPORT LOCAL AMATEUR RADIO COMMUNITIES
Giving help and information
At The Frys Hill Repeater Group, we are dedicated to helping the wider Amateur Radio community. Through cooperation and involvement with local Radio Clubs and other repeater groups, we believe we can help to promote our hobby and spread the "Amateur Spirit" of assisting others.
MAKE OUR SYSTEMS AVAILABLE FOR USE IN EMERGENCY SITUATIONS OR EMERGENCY EXERCISES
Helping The Community
RAYNET, the UK Radio Amateur Emergency Network local groups contribute to our running costs and make use of the systems during exercises or events. This regular use provides valuable operator experience and testing of the systems.
Everything we do is made possible by our generous supporters.
Without the financial support of our local Radio Amateurs, including local Radio Clubs and Raynet groups, we simply could not keep the repeaters on the air!
If you would like to donate to help support the repeaters and keep them on the air, we want you to know that every penny you donate will go to their upkeep.

GB3FI was installed to support users of hand-portable equipment that may choose to walk on the many areas of outstanding natural beauty in the area. INcluding the Mendip Hills, the Somerset Levels, the Quantock hills to name just a few. This repeater provides patchy but useable coverage throughout the Cheddar Gorge and as such proves a valuable resource for Raynet when they support charity walks in this area

CARADON HILL REPEATERS
GB3CH, GB3JL & GB7LK
There has been an Amateur Radio repeater station on Caradon Hill since the early 1970s. Originally, the repeater was on the main IBA mast but due to commercial pressures and the sale of the IBA Transmitter sites in the late '90s the repeater had to move off the mast.
GB3CH then moved to a small tower next to the IBA mast, owned by Rediffusion. In a few years, however, this tower was sadly condemned and had to be demolished and at this point, permission was sought by Matt, G4RKY to move 'CH onto the then SWEB tower at Caradon Hill. There was a low loss feeder cable in situ but a suitable antenna was needed and commercial riggers had to be paid to mount this antenna on the tower. The operation of CH on the new site commenced in 2004 and has continued, thanks to SWEB, now WPD Telecoms, ever since.
In 2008, James M1APC the then keeper added a 145MHz repeater to the site, using redundant mid-band antennas and GB3JL continues to work well.
During a recent upgrade to the UHF equipment on site (November 2021) a DMR repeater, GB7LK, that was donated to the group was added by Matt G4RKY and the GB3CH repeater was replaced with a new Tait unit and the frequency changed to a wide split channel. GB3CH is now on Allstar and you can connect using node 43678.
