I'm a bit busy, but if no one else takes the task, i can have a go at it
in bits. I was always deriving mathematical formulae for circuits as a
teenager. I was self-taught in RF/analog electronics before i went to RMIT.

I have just reconstructed the 36 year old NEC-2 documentation;
Part 1 http://www.commspeed.net/k7qo.NECpart1.pdf
I'd like to help. There is no equation on the planet that I cannot
make pretty using LaTeX and if you look at the 3D graphs, I can do
those too.
Let me know and I'll tell you how to get the copies to me. I'm
good at www.qrz.com in the FCC database.
