Well, not quite. Yes, 4nec2 files have a .nec extension but they typically do
not follow standard NEC conventions. For example, Paul's posted file contains
these lines:
SY len = 350 'Element Length
SY ang = 67 'Included Angle
SY hgt = 80 'Height AGL
SY x = len*sin(ang/2), y = len*cos(ang/2) 'Cartesian Angle Computation
GW 1 40 -x y hgt -1 0 hgt #14
"SY" is not a standard NEC card type and "GW" cards using non-numeric fields
are not standard. So EZNEC treats this .nec file as having an invalid format.
>>> The other way around works (4NEC2 imports .EZ files).
That also has a caution to it. 4nec2 will import simple .ez files but will not
recognize some of the things found in newer .ez files such as wire insulation
specs, transformers (baluns), or L-networks.
