By the way, on the subject of lumped inductances, have you
found or know of a method to model link coupling ?
My tests using non linked coupled circuits sort of agreed
with computor programs ( lumped spaced inductances) but
unfortunately that where it ends.
I sure would like to model a variometer which is a link
coupling but I don't see a way to do it.

Cebik's web page has a pretty good treatment of mutual
(link) coupling at http://www.cebik.com/link/link0.html

Yes, I pointed out Cebik link tutorial earlier this week
on another thread but it doesn't help with the computor modeling.
