ATU: Correct way to specify impedance range

... we ought to hold the ham manufacturers' feet to the fire to do something similar. 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 One of the reactions was that Smith Charts are obsolete and have been replaced by software programs that just provide the answers without all the effort and pain involved with understanding a Smith Chart.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 |
