All the site systems are powered by Solar Panels and Wind Turbines, which operate at High Voltages.

During peak winter months when there is little direct sunshine and quite often not a lot of wind, GB3JB can suffer from power outages.

Tampering with any part of the installation could be dangerous.

The above image is provided by the ETCC, and a more detailed map can be found HERE.

Obviously, there are other 2m repeaters operational on RV63, and users should be aware that under some conditions GB3JB could suffer interference from users of these other repeaters.

It should also be obvious that users of GB3JB could well cause interference to users of these other repeaters.

It is good operating practice, to only use the power that you need to be able to access any repeater.  Therefore, if you only need 5 watts to access GB3JB, don’t use 50.

Site Safety & Security.

Obviously, at a site with a relatively easy unauthorised public access, safety and security is a priority.

We therefore try to do our bit.  A couple of examples are shown opposite.

We have signs warning not to climb the tower.  Even though we have installed anti-climbing panels, idiots will always be idiots.

We have also provided warnings as to the use of 24 hour CCTV facilities on the site, which cover both the internal areas of the locked and secure barn and the external areas outside of the barn.

If you are not directly associated with the servicing and maintenance of GB3JB and it’s associated equipment and facilities, or directly associated with the farming of the land itself, you enter this privately owned site, totally at your own risk.

There is no public right of way across the site, and no unauthorised public access at any time.
