Im not finished with it. It needs the heatsink and coax at each end but other than that looking good so far.

Not yet electronically but I have got some boards from enigma shop and will be ordering the components from mouser very soon.I’m gonna try some different caps that’s are cheaper and rated 1000v on the output.

These devices seem like the way forward especially if they are going to get taken.

Go for it. The kits are made of smd easily put together. However if replaced with your caps they should be simpler that way you know its easy to identify.

From my past I've watched my mates blowing up transmitters from not listening to me. So now there now like should have listened I haven't blown transmitter since 1999 in which case I used a car battery. I blown it stupidly using it while it was charging on air. I thought the Germans was flying over again that day it was loud bang lol
