Hi Guys - perhaps we need another column - "Stuff-ups I have made"! Some are pretty frightening. Many years ago I had to retune a 400watt AM beacon transmitter to a new frequency. The antenna was connected inside the shed with 1/4" copper tube which was earthed by a grounded clip when servicing. Couldn't get this Tx to tune properly, lots of output current but no power. Then my mate says "you haven't taken the ground clip off" so he hops up on a stool and takes the clip off the copper. Now the Tx put out some power! Drew quite a good spark about 2feet long before my mate dropped the clip. We sat outside for a while and had a smoke before checking on the damage - fortunately none!
Regards - Marty
