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,

winSMITH 2.0 automates the graphical solution of transmission line and lumped
element matching networks. It is also an excellent training aid for RF and
microwave circuit design.

The power of the Smith chart is the ability to present complex data visually,
making possible informed judgments regarding transmission line systems, measured
data, antennas, matching and other networks.

winSMITH simplifies the process by replacing the paper chart, a pencil, compass
(and eraser!) with computerized screen graphics. It offers the speed, accuracy,
and repeatability provided by the personal computer and instantaneous data
readout in multiple formats. This program is for Windows 98 and XP.
