It appears that there are some new subscribers to the list who
may not be familiar with the NEC material currently available on the
net.
The following list shows what is currently available on
ftp.netcom.com/pub/ra/rander/NEC (and also mirrored on
ftp.emclab.umr.edu/pub/aces/NEC).
If anyone has additions and/or updates for the archives let me
know at rander_at_netcom.com .

nec_docs_order_info.txt
Provides info on ordering official NEC2 documentation
from the government.
wiregrid.zip WIREGRID is a NEC2 pre-processor for DOS PC's that
was developed for modelling metallic structures using
a mesh of wires. It has powerful automatic facilities
for controlling the density of the mesh once the structure
has been broken down into a number of polygons. It can
also be used as a general NEC2 pre-processor. It was
originally written by C.F. du Toit. Note that the code
uses its own data format, and unfortunately CANNOT import
an existing NEC2 model file, but it can of course export
the model to a standard ASCII file. A description of the
pre-processor has been accepted for publication: "WIREGRID:
A NEC2 preprocessor", C.F.du Toit & D.B.Davidson, Applied
Computational Electromagnetic Society (ACES) Journal.
(To appear.) A draft version of the paper (minus
illustrations) is contained in the ZIPfile. The code was
compressed using PZKIP version 2.04g.
(wiregrid.zip Version 4.00 A now online 9/8/94)
from Dr. D.B. Davidson (davidson_at_firga.sun.ac.za )
nec_examples.txt
This collection of NEC2 input data files is provided
courtesy of the Internet and Raymond Anderson. These input
files may be used for the NEC-PC programs, I've tried them
on both, but have been using NEC2D primarily. NEC2D was
provided by Jozef Bergervoet. I tried to give enough
examples so that the control cards for input would be self
explanatory. Also most types of antennas have been included
such as log periodic, monopole, rhombic, deltaloop, Quad and
the YAGI. These files are easily adapted and modified with
the DOS edit function, using the search and replace features.
Good Luck on your antenna designs- Clyde Edgar WA6DCM

somnec.tar.Z
This file contains the FORTRAN source code for the
SOMNEC utility described in the official NEC2
documentation, as well as a sample output file
and a brief text file containing a general discussion
of the program.The SOMNEC program generates grids used by
the NEC2 program for the Sommerfeld-Norton approximation
to realistic grounds.

somnec_readme.txt
This is the text file contained in somnec.tar that
provides a general discussion of the program.

gamtoz.zip
GAMTOZ is a program to convert MicroSmith .GAM files (such as
produced by ELNEC and EZNEC as well as by MicroSmith) to comma-
delimited files containing impedance values. Both source code
(GAMTOZ.BAS) and a compiled (DOS) version (GAMTOZ.EXE) are
included. (This copy virus free!)
from Roy Lewallen W7EL
lpcad.zip LPCAD is a program to design log-periodic antennas. Antenna
specifications are input and the program calculates the
physical lengths and spacings. A NEC or NEC for Wires input
file is then automatically created. lpcad.zip unzips to
produce LPCAD1.EXE and BRUN30.EXE.
