 Thank
you for visiting this
site. Most of
the content is amateur radio
related, but there
are also pages on small
islands, mirages and our
family history back to 1428 in
Devon. I hope you enjoy the mixture.
If you have suggestions for new content or comments
on the site do put something in the guestbook
or send me an e-mail.
Having now
retired, I'm able to do more QRP ham radio,
so expect a few more
pages to appear on this site in the coming months
and a few more
articles to appear in the magazines.
When you've had enough
here, take a visit to some
other sites on the QRP web
ring (see bottom of the
page).
