I am an electronics engineer/educator/technical author who has worked and taught in many countries.

I have owned and used a hydraulic ram at my off grid U.S. home for many years. One Wikipedia goal is to add additional information about hydraulic ram theory, operation and problems. I appreciate any feedback and suggestions from other contributors.

A second area of interest is in theory and practice of antenna and transmitter technology. I have contributed extensively to ARRL publications in these areas. I hope to add to the sections on AM radio, broadcast and amateur practice and history.
