SimSmith Updated

SimSmith is Smith Chart software that was introduced and described in an article in QRP Quarterly earlier in the year.  I recently made some substantial improvements to SimSmith.  These are:

  1. Added a library function to allow you to save and restore tuned circuit elements.
  2. Added some new components including a transformer.
  3. Added a ‘print’ function
  4. Improved the ‘save’ and ‘load’ commands.

If you are interested in getting the newest update or in learning about Smith Charts in general, please visit my page

The newest version in 4.2.  It is written in Java so you need only download “SimSmith-4.2.jar”. There is no installation necessary, only a working Java Runtime Environment.  This code has been tested on Macs, Windows, and Linux.

I haven’t tried it yet, but it sounds pretty cool to me.

    It is, by far, the best Smith chart program I am ever used. You can draw your own matching circuits and load in measured or modeled load impedance sweeps to get a real feel for how the circuit works. Big kudu’s to Ward.
