[CW] Crystal Amplification and Magnetic Amplification

[David Ring]

Thank you Al, it is always good to hear from the old timers who were there!

I also received a message from radio historian Thomas White about the
subject and I share it with all of you.

Mr. White's website, http://earlyradiohistory.us/ is very interesting
and informative.  I recommend a look when you have time.  His message
is below.

Hello everyone!

This is a little latter than the period you post covers, but
I have a few articles about this topic at my web site. First
is a short review of a simple oscillating crystal circuit
designed by Greenleaf W. Pickard that appeared in the
March, 1920 QST:

Later, in 1924, there was a short flurry of excitement
about the work of O. V. Lossev that was covered by
Radio News in articles that included "A Sensational Radio
Invention" at http://earlyradiohistory.us/1924sens.htm
and "The Crystodyne Principle" at
http://earlyradiohistory.us/1924cry.htm
