I suspect their average amateur radio customer doesn't understand the meaning of 1000+j1000 much less comprehend graphs on a Smith Chart. I recently published an article over on eHam.net that contained a Smith Chart. One of the reactions was that Smith Charts are obsolete and have been replaced by software programs that just provide the answers without all the effort and pain involved with understanding a Smith Chart. One doesn't need to know anything about hyperbolic trig functions any more. Just point and click. -- 73, Cecil, IEEE, OOTC, *http://www.w5dxp.com Hello Cecil, I was expecting that this only happens in the Netherlands. I have some (modern) software where the default plot method is Schmit Chart... I agree with the contour plot on a Smith Chart showing losses (and power handling) for Antenna Tuners.
