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 adding new items I am restructuring 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
