Default Current through coils

Cecil,

I have no idea what you did, but you screwed something up quite royally.
There is no way that segment 3 is too close to segment 197.

I just ran a cut-down version in the EZNEC 4 demo, and I found no
geometry errors. Yes, each segment length is too short, about 80% of the
recommendation, but Roy indicated a couple of days ago that should not
present a big problem. I cannot say much more about EZNEC, except that I
did not see any problems.

The coil I modeled is very similar to the Texas Bugcatcher model 680
coil. ( http://www.texasbugcatcher.com )

I don't own a Texas Bugcatcher coil, but I suspect they actually work
more or less as advertised.

73,

Here's just about all you need to know about Gene's EZNEC file:

EZNEC doesn't like 4 TPI coils at 4 MHz.
