[Boatanchors] Crystal Radio Drives Speaker

[Ken Woodside]

Hello to all!  I am requesting some assistance trying
to find a copy of an old magazine article... The
article described how to build a crystal radio that
would drive a small speaker (with powerful local
stations) without battery power.  I was fascinated by
the concept, but never had a chance to build the radio
due to lack of time etc.

Now, my interest has re-emerged but I have lost the
article.  I believe the article was in Popular
Electronics magazine in the time range of late 60's to
the early 70's. Does anyone out there remember such an
article and better yet does anyone have a copy?

Many Thanks for the time and consideration.
73's
