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
