Hello,
I've been following the thread looking for Don's book. I am not looking for a book, I have a copy but I am interested in finding any information about Don. When he was posting here I've saved a few of his posts, always very good interesting information.
Here are some sites where Don is mentioned.
I tried sending an email to one of the clubs but no response. As you can see he is also a ham radio operator.
