Take
a look at our first crystal radio
web site.
These
pages were part of another web site having nothing
to do with crystal
radios. They were split off the other web site
and were the start of the present web site dedicated
to crystal radios
only. I added
the crystal radio plans section and the
name "Stay Tuned" and "Stay
Tuned" was born and on it's
own.
Web site built in end of 2000. Announced open by
Owen Pool on 6 Jan 2001
