I've been looking at a number of simple crystal radio designs, and I've found the Australian mystery crystal set, and am interested in building that, mainly because it's an Australian design, and I've heard it it's a pretty good performer. I only have 2 questions- can I substitute the detector for a 1N34? and what is double silk covered wire and do I really have use that? What's wrong with regular coil wire? I can only find 23 SWG, 25 SWG, and 33 SWG where I need 24 SWG,
30 SWG.Thanks
Dave
