ABOUT THIS BOOK
WHAT IS A DUPLEXER?
Building Your Own Cavity Duplexer
At that time I also began to write a book to describe my experiences, that you may access to the left. I wanted to be of assistance to other hams who might want to duplicate my efforts, or at least better understand the duplexer(s) that they already owned.
I never totally finished the book. So rather than continuing to pack the unpublished manuscript around with me, I offer it here in its unfinished state. I'm sorry that there is nothing still existing, diagrams, plans, etc., than what you find here.
