Can anyone recommend any tutorials for learning how to read a smith chart and also using the Sim Smith application ? I want to be able to design coax matching stubs and am a total newbie. The smith c
Thanks Jerry, I found it in the handbook. I found some on line when googling too but I want to start out at the beginners level. The ones I found assume you have a basic knowledge of the Smith Chart.

Paul, I will check out the QST articles. I attended the excellent seminar at Pacificon on Sim Smith by Jim, K9YC. Its all his fault. Now I want to learn more about designing coax matching stubs. hihi
