Thanks for the correction regarding proximity effect. In that case,
Reg's program should report the loss more accurately than EZNEC when the
turns are very closely spaced.

Yes, indeed, EZNEC does account for the capacitance -- it comes about
from the coupling of fields between turns, which is at the heart of the
fundamental NEC-2 electromagnetic field calculations. As I said, the
self-resonant frequency reported by EZNEC is pretty close to that
calculated by your program.

includes proximity effect, either.

======================================

Yes it does!

But you can forget it. It doesn't matter except when calculating efficiency.
It has no affect on how the thing works which is what you are all
so-aggressively fighting about. You'll soon be using assault weapons.

Program "Loadcoil" also includes the ALL-IMPORTANT COIL CAPACITANCE (which I
suspect Eznec does not - I never use it) - the existence of which the
whole set of you block-heads, so-called electrical engineers, appear to be
entirely ignorant.

We ARE dealing with alternating currents.

Oh Boy - I enjoyed typing that! ;o)
