Many thanks to the guys from the golf course for returning our tail along with one of our blades, which was found some distance into the golf course! Cheers guys!

Many thanks to the team who travelled all the way up from Plymouth to help us with our failed backup generator.
After much hard work and many trips walking up and down the muddy field it was found that as the main alternator shaft had been sheared off nothing more could be done on site.
The engine and alternator was removed from the trailer, man-handled and carried all the way down the hill in the dark so it could be taken back to Plymouth to be worked on.
The team also lowered the GB3WB mast so that the damaged wind turbine could be worked on.
Also many thanks to Neil G7EBY who travelled all the way up from Sailisbury to work on the failed equipment with us.

In the tremendous winds of the morning of 05/01/2011 at 1am the tail was broken off of the GB3WB wind turbine. This had the disastrous effect of stopping the turbine from auto-furling.

This left the blades facing the wind, which caused them to spin at thousands of RPM until they were all broken off. This is a disaster for our repeaters.

It is worth noting that our modified oil-filled heater 24v dumpload worked perfectly day after day and saved our expensive battery sets from over voltage charging and burning out.
Other repeaters running from wind turbine power not so far away lost their dumpload, which in turn destroyed their battery sets. They also lost their mast and antenna. It was a real nightmare for us all!

We have currently turned off the repeaters to conserve the power in the batteries.

A new tail and set of blades will have to be bought and fitted asap so that the repeaters can be activated again.

GB3WB Wind Turbine Modifications. The GRP blades have now been balanced. New tail pivot spring brackets have also been fitted. A second 12 way slip-ring has been fitted inside the main 3 phase slip-ring so that other equipment may be fitted onto the turbine to monitor its preformance or send other data. At the moment LED’s have been fitted to each circuit to test them.

GB7WB Turbine view of Glastonbury. Now that our highest omni antenna and wind turbine have been swapped over, the turbine can just see over the tree which has blocked most of the wind from us for such a long time. Our two towers are still at the same height, simply the head-loads have been swapped over. The omni antenna is now on our lower mast and our wind turbine is on the taller mast.
