Knocked this up a while ago in a quiet hour at work. Rebuilt today to reduce flex away from the contact points, as it felt far too floppy, and installed the front screw+nuts as a stop to further tighten up the general feel and behaviour. Much nicer already, feels crisp.hacksaw_paddles

magloop antenna

Built a magloop out of some kind of copper pipe I found. Pipe is nearly 16mm diameter. Capacitor is 2-gang and looks spaced for nearly 4kV. I’m not sure that it’s large enough so I may parallel some fixed caps onto it, about 20pF if I can find something.
