Welcome to my technical web site which is dedicated to RF Communications, Test Equipment and related topics in both old and new technologies plus a few non-electronic ideas. New items are regularly added and subject related items are being re-grouped within the highlighted menu fields for ease of access and future expansion. A number of example PCB layouts have been added to their respective circuit pages.

The site map shows the relative positioning and links to all pages on this site.

If you have any questions or comments on the contents of this site please email me at G3OOU(at)AOL.COM - replace (at) with @ when emailing.
