I will be taking the ARRL course

http://www.arrl.org/cce/courses.html#ec004

starting Oct. 1, 2004.

The course outline mentions the use of EZNEC 3.0 or NEC-Win or "or that
you are willing to adapt the ideas that we shall explore to the package
available to you."

Has anyone taken this course using 4NEC2 by Arie?

Is it reasonable to take this course using software other than that
recommended?

Thanks.

Thomas
