My EE classes focused on plotting the characteristic curves of vacuum tubes
(late 50's). Semiconductors were left for us to learn on our own.
This was my first radio, followed with a Meissner kit using type 76 triodes
in regen/audio amp combo. I also mistakenly said the crystal was germanium
but

seems, my first experience with a semiconductor device, was with an

Hello,
I would like to say thank you to Chuck for the initial
e-mail and all the other guys with their comments.
I also would like to thank the Elecraft Monitor for allowing
the thread to go thru the system.
This has brought a lot of memories flooding back to me from
my earlier years.

When I taught physics, it was a requirement that all my students build a
crystal radio ... great fun by all and a couple went on to get a ham ticket!
When I was in 5th grade I built the "Fox hole radio" and never got it to
work. An old time gave me this tiny glass tube with two wires sticking o
