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 http://www.wolfram.com/cdf-player/ I am open to suggestions: w9he@arrl.net
