The imped_admit_smithcart I found on the web.

I do know how to draw a Smith Chart, see the notes2012.pdf
file.  The examples in those notes were done by me by hand
directly in Adobe PostScript.

The Log and Trig Tables are for people whom do not have
a scientific calculator.  They are sufficient for any of
the tests and if unmarked, then may be used at the tests.

The NoSmith version is only missing the Smith Chart which
also present in the Extra Class Graphics materials.

The w9dup files are Aximuthal Equidistant maps center on
Westmont, Illinois.  They show the direction to point your
antenna and the distances from the center of the maps are
to scale.

The Whetstone,cdf file is a interactive Whetstone Bridge
emulator using Wolfram CDFplayer technology.  You can avail
a free copy of the Wolfram CDFplayer at
