NEC-2 and NEC-4 have different formats for the GH 'card'. This is the
NEC-2 format, which will be interpreted differently by NEC-4. See your
NEC-4 documentation for the correct NEC-4 format.

Thanks Roy, now you mention it I do remember that there are some
differences. Should have checked with my manual before running it instead
of just cutting and pasting NEC 2 code. Made the appropriate correction and
it is now working with a reasonable correlation with NEC 2. Heck, now I
just noticed I had entered the wire diameter instead of its radius!
