Copyright, Linking and Other Legal Matters


Except as noted (Manuals pages have a separate copyright statement), this entire site is copyright Didier Juges, © 1990-2019, in accordance with US and international copyright law.

You may copy, distribute, prepare derivative works, reproduce, introduce into an electronic retrieval system, perform, and transmit portions of this web site provided that such use constitutes 'fair use' under copyright law, or is otherwise permitted by applicable law.

Check the Fair Use web site maintained by Stanford University for reasonable fair use definitions and assumptions.

In addition to circumstances already allowed under the law and those listed on the Stanford University web site linked above, copying for publication on another web or ftp site is allowed under the circumstances listed below. For any other purpose, e-mail me and I'll be glad to work it out with you.

  • Material on this site can be copied for use that is both personal and non-commercial. Copying to paper or other media (except publicly accessible web or ftp site) for educational purpose or for ham radio clubs presentations or other specific, not for profit purpose is encouraged and does not require prior approval, even though I would appreciate notification.


  • Copying for publishing on another web or ftp site is allowed for material originally published on that you may have downloaded for personal use, and which may later become unavailable because the domain disappears or changes ownership, or the material is removed from this web site. I personally believe that while copyright laws are generally a good thing, the laws have been excessively modified to benefit the entertainment industry, resulting in rendering unlawful many legitimate and previously allowable uses of copyrighted material. I do not want the copyright laws to get in the way of the legitimate public interest in material I have generated. Of course, as long as is owned by me, and the material is available from this site, you should refrain from publishing it on another web site or publicly accessible server, other than under circumstances covered in this document.


  • If material is republished, according to the conditions above, you must indicate the source of the material.


Linking to this web site is encouraged, as long as you do not misrepresent the content, purpose or origin of the page that is being linked. If you link to material from this web site, please include a visible reference to where the material is located, so that someone printing the page gets the link information. An example of what I mean can be seen at my Ham Radio Links page.

Even though I do not often revamp the structure of my web site, it does happen on occasion. Therefore, rather than providing direct links to pages deep into the web site, I recommend linking to the main page with human readable instructions for how to get to the proper page, so that your links would still work if I change the organization of this web site. For example, instead of linking to, link to and instruct to look for the Manuals page.

If you link me to your site, send me an e-mail and I'll be glad to reciprocate as long as your web site is non-commercial and does not require mandatory registration.


I accept no responsibility or liability for problems resulting from your visit to this web site or from your use of material from this web site.
