Watkins-Johnson Company published WJ Tech-Notes on a variety of topics relevant to microwave communications for almost 20 years, starting in the mid-1970's. While some of these notes have become seriously out of date, many retain their relevance, since the fundamentals of physics and electrical engineering haven't changed. They are available, organized by volume at (vol. 1 - 18) at 

Watkins-Johnson Application Notes.

Welcome to the KONG DX-pedition page. Our ambition with this page is to inform the DX community about the results of the DX-peditions held here. Inside, you will find all the logs, details about antennas and receivers, participants and menus (!), DX-related links and some non DX-related links. There is also some general information about the location, since we believe that it is worth visiting even if you donít plan to DX.
