There is a well know law of electronics that if you have a fiull set of spares for an item it is very unlikely to go wrong!
During the rebuild of GB3KBQ, due to the generocity of individuals on this forum, I was able to build an 'almost' spare driver unit for the beacon.
What I am missing, to complete a spare unit, is the 108 MHz - 10GHz multiplier. This is a Continental Microwave / Frequency- West Microwave PLL multiplier 'Brick'
These were commonly available at round tables and rallies a few years ago.
If you have such an item gathering dust and surplus to your requirements ..I can find a good home it!
