Welcome to my technical web site which is dedicated to RF Communications, Test Equipment and related topics in both old and new technologies. As well as regularly adding new items I have restructured the site to simplify this opening page and move items into subject related groups using the highlighted menus below to provide for future expansion. A number of example PCB layouts have been added to their respective circuit pages.
The site map shows the relative positioning of 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.
