While we are looking back, a major contributor we should remember
is Brian Beezley, K6STI, who pioneered much of the NEC code and
produced Yagi Optimizer, Antenna Optimizer, and Terrain Analyzer in
the 1990s on early DOS machines. These programs placed
sophisticated computer design of antenna systems in the hands of
amateurs long before ELNEC, EXNEC and HTFA.

We've all been blessed by fellow Hams who took their time and
perhaps advantage of their job duties to bring us all sorts of
goodies. CQ Magazine for years had a propagation column that none
of us could have afforded on our own.
Dean worked up to HFTA over the years. Whether just translating
from Fortran or doing a complete rewrite makes no difference. It
gives us at least a good place to start. Moxon the same. Cebik
apparently took a big leap in learning and investigating.
There has been some comment on verticals on slopes. Read Moxon's
book.
Time and personal thought processes move on. Sometimes the
source code gets lost one way or another. But as with one
propagation program I use....often if a program gets sold the
price goes way up and the code still isn't there to examine.
Thanks to all those guys who don't remember what they did for us.
