You thought you would never use trigonometry after school. Perhaps you though AM radio was dead?
While I have been busy posting VK5JST Antenna Analyser kits for the HAM radio club, Erich has been busy circuit bending!
Its a devious hack! I dare say very unsupported by the kits designer Jim VK5TR/VK5JST.
But as Erich says "if you can't modify the software in the box, you don't own it".
I wonder what other kinds of hacks one can build up from the kit?
