After my latest adventures with my Auto ATU and adding a jumper wire I was having some odd behaviour so a club member Dave G8KBB offered to take a look and give me a second (and far more experienced) opinion.

It turns out I somehow jumpered the wrong trace and there was also a soldered end of wire which wasn’t cut short enough and was therefore prone to short out, silly things as usual! Dave has jumpered the other trace, cut short the wire and advised that I box it up ASAP and add a fuse to the power cable.

Many thanks to Dave for the assistance and advice!
