This impedance meter is based on SM6MOM's winning entry in the RF Design
Magazine contest in 1986. As I pointed out to the then
editor of the magazine, the exact same impedance meter was described
in the Proceedings of the IRE in 1947. You might want to read the
article by the original inventor (I believe his name was Samuels and the
title is something like "A Oscillographic Method of Impedance Measurement".)

In a recent thread on VHF impedance measurement, it was indicated that
VK2ZAB had instructions for building an impedance meter. I have acquired
all the parts needed for constructing a meter described in ZABs article.
But, I am confused about how to operate it when/if the meter gets
finished.
I'd sure like to corespond with someone who has built and/or used one of
these meters.
