Very limmited edition mugs. Thanks to all who bought one and helped boost the groups funds. Remember those who have one, there are only 10 of you in the world with one of these mugs! look after itl
But things to go wrong. Take a look at our sad looking 4 stack antenna. What could have happened?
We had to get a rigging team in to take down the failed antenna and replace it with a brand new one.
Alloy fatigue. The Aluminium simply rotted it was very crumbly to the touch.
Parts recovered from around the tower. And that my friends is why you wear hard hats when working around them!
Solder in the parts. Almost looks good! next the IC's
Of course, occasionally even we stop for a cup of Java.
These bits were found around the base of the mast.
The failed antenna was only 14 months old. Thankfully the manufacture accepted a design flaw and replaced the unit Free. Although we still had to pay for the rigging team.
Alloy fatigue. All four elements suffered the same fate.
The Repeater Group was honoured to be presented with the G8HPC trophy for outstanding contribution to amateur radio by the North Bristol Amateur Radio Club (NBARC)
