You must NOT copy any of these pages and place them on your own site unless I have first given my written permission and the original source of the material is attributed. This is usely no problem for recognised educational institutions.

I assert the moral right to be identified as the author of this web site and all contents herein. It is my intellectual work and I zealously protect my intellectual rights.

Everything is copyright and, beyond the definition of "fair use" I will prosecute both civil and criminal proceedings for abuse of my rights. At the moment I regard each page on this site to have a commercial value of $US 1,000.00 per day of breach.


I have had numerous requests to link to this site, which is of course particularly welcome, as our mission is to spread interest in and knowledge of electronics in general and amateur radio in particular. It is usually not necessary to ask permission ahead of time (though I am always glad to know by email who is linking to me if only to keep them updated). However, there have been a few instances which prompt some guidelines in the interest of fairness.

Firstly I would rather you actually link to particular pages your topic refers to. Most pages have details on how to link. In the event you would prefer a broad link to this site then my second preference is this one particular page This link will always contain the latest pages on my site and your visitors will not become disappointed by later broken links.

Anyone with a Web page is welcome to link to any part of this site, under these conditions:

You may not imply our endorsement of a product or of your site. Unlike some sites, we don't necessarily object to (but then again we don't exactly encourage them either for obvious reasons) having our pages placed in frames, as long as they do not distort our document and no endorsement is implied.


If a link to us is placed on a page that uses frames, you must plainly show the origin of our page!

Either the page's URL, or if it does become available, our logo needs to appear in the immediate vicinity of the hypertext link or icon that connects to our page. Use of frames to obscure the origin of material is to imply that it resides at your site, which is not fair to us or to any other page's author and would certainly invite action.

If you link to any part of our site other than the home page, please check the link(s) periodically, to ensure that your readers will not be disappointed if we move the page elsewhere or discontinue it.

If you want to send me an email regarding your link back or anything else please do so.
