Ok guys it's your faults that I'm not getting any work done tonight. All this talk about ancient electronics sent me on a trip down memory lane and I wandered around searching for images of past memories.
First of all I didn't even know about crystal radios. I had to go look that up. I'm surprised it escaped me but I may have used one at some point without knowing what it was. It's possible because at the time my father worked as a Signals and Communications technician for a large mining company and often brought home scrap electronics that my brother and I would try to revive. I quickly realize that it wasn't my cup of tea but I did enjoy use of the technology (my younger brother actually went on to open his own electronics repair shop that he still runs today).
The extent of my knowledge of crystal technology is limited to the RF crystals in my old Johnson Messenger 300 Classic CB Radio. As for vacuum tubes (valves) -- that's what my Geloso G4 Wumpus HAM receiver ran on. I remember it so well and can still feel it today -- the electricity that is -- it had a grounding problem. I never was able to figure out the cause but I eventually got used to the shocks :)
follow the smoke?
