Yep... Crystal Sets are all high-tech, looking at a Regen-kit a few weeks
back I got it is *still* cheap and low tech ( other than the 1T4 tubes).
See the hi-tech coils here.

transmitter crystals or beg one. A 6v 150 ma pilot lamp
would serve as an adquate plate current indicator. Coils could be
easily hand-wound.
You mean it's all changed now? :-( -tony
The big thing it is not using a RF choke for regen, and I think
that is the biggest problem.The other thing I think it could
of had plug in-coil rather a fixed multi-tapped coil. Still parts
are cheap, and I can rebuild the design on pine board
with new ideas.I can take my time, since I have *No* AM stations
out here.
