Here's the definition of "ordinate":
"The y-coordinate on an (x,y) graph"
I'm not sure what you are asking for. The graphs were
generated by Excel. What exactly are you saying? Do
you want me to add the dots for the data points?


Let me apologize in advance to the group for being forced,
reluctantly, into the pedantic exercise which follows.

Dear Cecil -
As of this moment there are no numbers on your y-axes to indicate how
many degrees your plots represent. You will need to tell Excel that
you want to have numbers there - and not just any numbers. You want
numbers that represent the value of the y coordinants for points on
your plotted curve. You must program your Excel spreadsheet to do
this because it is no more omniscient than the people who would view
your webpage.

I'm not sure what you are asking
for. EZNEC is a great piece of software but the calculating
engine is NEC. I doubt that even Roy knows the NEC equations.


Well, it's become apparent that you don't know them. Even still, you
claim be wiser than Kraus on this subject. Certainly bold, if not
altogether ludicrous. And all this is for no reason other than the
fact that you can run a program that you didn't write (the author of
which you relentlessly berate) to perform calculations that you can't
explain.

Well, you damn idiot, at least you no longer dispute it, you just
dispute how much you have been in error. My gawd, we are actually
making progress! 8-)

This is simply a false statement, Jim. I see the numbers on my
y-axes when I click on coil505.xls and open it with Excel. I
see the numbers on my web page using Firefox and Explorer. But
whatever problem you are having, I'm willing to help you solve
it. How have you managed to make the y-axis numbers disappear
so you can give me a hard time about it?

Well, it's become apparent that you don't know them. Even still, you

Well, Kraus has a problem that I don't yet have - he cannot
learn anything new. Dr. Corum's calculated VF's for coils
seem to be more accurate than Kraus's based on my EZNEC
simulations. Where Kraus gets 0.006 for the VF of a 75m
Texas Bugcatcher coil, Corum gets something closer to
the 0.016 reported by EZNEC.

P.S. I'm deliberately ignoring the ad hominem attacks in
your posting. Why can't you just state the technical
facts without waxing so extremely nasty?
