I'd appreciate any recommendations for an inexpensive Smith chart based
program which can be used for the design of basic matching networks and
the like. I'm looking for something along the line of MicroSmith or
WinSMITH, neither of which is any longer available.

Thanks,

Hi Roy,

There is a very slick one Switzerland:
http://www.fritz.dellsperger.net/downloads.htm
from Dr. Fritz Dellsperger.

It, like your software, has a free but limited use. Getting the full
use one is rather more obscure as there is nothing mentioned at his
site as how to get a key or otherwise obtain full use (more than a
limited number of points). Somewhere, there was the suggestion of
accommodating a user if they emailed, but that never worked for me.
