I'm not reporting the results, Jim. EZNEC is reporting
the results. Choose the "Loads Dat" display.

Have you ever even looked at those files?

To my knowledge EZNEC has never reported a single result to this
newsgroup, Cecil.

Choose the "Loads Dat" display.

I looked at travstnd the first time you posted it, and I even
commented to you about it. I assume that coil512.ez is what you used
to create the plot on the left that says "No Phase information in the
Magnitude" and has the words "Straight Line" by the straight line.
It's all very scientific. :-)

Let me ask you this: how would you go about calculating the phase
shown on your Standing Wave Current graph, and what meaning if any
does it hold for you?

Kraus already did it for us. Note the relative phase
graph.

The phase shown on my Standing Wave Current graph is
the phase relative to the source phase. For a pure
standing wave on a 1/4WL wire, the standing wave current
phase is everywhere equal to the source current phase.
That's why it cannot be used to "measure" the delay
through a wire or through a coil.
