Smith Chart and NEC Links
« on: June 04, 2013, 08:36:11 PM »

I was asked by KD6GN for Smith Chart info. 
Here is the e-mail message I sent him.
I thought other participants here would be interested.... 
Jim, K7JEB
Here's the website for JJSmith, the Smith chart program
I had a hand in writing.  First is the top-level page
for Tonne Software, an enterprise by my good friend
Jim Tonne, W4ENE:


And here's the link to the program download page:


Here are some other websites that I've found have
interesting info on them:


This website requires Java to run, but is very


This is another Java-enabled on-line Smith Chart


This is the "Smith Chart Society Reference Page"
There's some good info on it and some hi-resolution
PDF's of the Chart.


This is a nice PDF of the Chart, suitable for printing.


This is a basic tutorial, an easy read.


Another tutorial, a bit more advanced and mathematical.


A plethora of articles from VK1OD.


Another printable Smith Chart in PDF format.

We spoke of the antenna analysis programs based on NEC-2.
Here are the websites:


This is the website for the EZNEC program written
by Roy Lewallen, W7EL.  It's worth a look-see and
perhaps downloading his free, trial version.


This is Arie Voors' website for his 4NEC2 program.
It's worth a bit of exploration as well.  4NEC2
is free, and capable of handling very large designs.
It is a bit harder to use than EZNEC, but also
closer to the "bare metal" of the NEC-2 code.
