Bart -

Just finished checking the K factors for Kurt Schraner's BW coil of
11/24/01.
Pos = Secondary above Primary in inches.
Mark = Mark Rzeszotarski's MandKver31 program. Thank you Mark.

This is a large secondary coil 15.8" dia x 70" long. It is interesting that
the program outputs come closer together as the coil is raised and the K
Factors become smaller. As I said all the program outputs will be equal at K
= zero. We must be doing something right. (:})

The data is entered in Java with password "Kurt1".
I couldn't find if Kurt made any K Factor test using the mutual inductance
test or the frequency test.
