When I asked for some references to simulation programs I got some really
helpful responses. As promised, I will summarize the most promising ones here.

FREE:

Bob Perlman was very helpful and has written a simulation in MathCAD.
MathCAD has the ability to generate an .avi file which is really neat. I
upgraded my version of MathCAD and the technique is truly elegant. I wish
Excel and Quattro had the same capability. Reach Bob (with his permission) at
http:/www.best.com/~bobperl/course1.htm

HP has an outstanding resource for technical training stuff at
http://www.tmo.hp.com/tmo/iia/edcorner/English
There is much stuff here, but the transmission line simulation is under
Spectral Simulation
   AC Circuits
      Wave propagation along a transmission line
the specific URL is as above plus
/Sexp8.html

There is also an excellent java simulation and small tutorial at
http://www.ecse.rpi.edu/Courses/F97/35210/java/Transline/tr_lines.htm



Commercial with some demos (none of which I have evaluated)

http://www.sonnetusa.com

http://www.hyperlynx.com

http://www.intusoft.com

http://www.aplac.com
This looks interesting, but the demo is 7.6 Megs and the handbook another 5
megs or so. Haven't tried to download it yet.

http://www.artech-house.com
This is a book publisher/reseller with numerous titles. One is TRAVIS Pro
which is a computer transmission line simulator with a price of $295 !!


Thanks to those who helped me put this list together
