You're a very good man, Phil.
I haven't looked at the changes that you said you made yet, but it sounds like it'll be fine. I was certainly not going to make a federal case out of this, like I've seen some people do.
And there is such a thing as "fair use" where permission does not have to be obtained from the author to re-post a small part of author's copyrighted work. (Note that some of what you copied from www.w0btu.com
was actually copied by me from others.) But for copying huge blocks of text, I don't know. You can Google "fair use" if you'd like.
I've read that if we copy someone's work, even under the fair use thing, that we should at least have our own copyright notice, such as Copyright (c) Phil Lastname 2013. All Rights Reserved.
to help protect it all. I've also seen, in addition to crediting the author and making a clickable link to the original, the phrase "reprinted by permission". Sounds like a good idea, doesn't it?
You are not the first one to copy some of our work. We make our living on the Internet and also have some commercial web sites. I have seen our competitors steal stuff off them and post them on their own sites, in direct competition to our company. Naturally, that sort of thing made us angry, and we certainly did something about that, in most cases.
Anyway, I looked at a few of the other things you have there, and it looks very useful. I've always wanted to see the "Big Gun's Guide" to low band propagation you have there. (And it looks like the author of that work has already given permission to copy and redistribute it for non-commercial purposes.)
I don't think so, but I may still have some things on my own site that I shouldn't. Originally, the stuff in the /files/ section was on my hard drive for my own use. I decided to upload it a few years ago.
Thanks again. :-)
