This was just posted two days ago, and it is pretty thorough and easy to follow.

Enjoy.

I think most people avoid smith charts because they think it will be akin to learning calculus.

This is one part of the radio hobby that can be learned with just a picture book. Some really basic rules control how inductors, capacitors, resistors, transformers, coax etc move the chart. Its like a slide rule for complex numbers and one doesn't even need to understand complex numbers to use it.

People shy away from complex numbers because they assume it is difficult. Smith charts were invented specifically to make it easy for everyone to solve matching problems without a calculator. Its the ultimate cheat sheet. Edit: and if your eyes are bad, you have simsmith, you can do it on the screen.

The Slinky demo reminds me of Physics class where Slinky's were used to show that different waves pass through each other.

Those guys had fun making that video. How did they print that king-size Smith chart laid-out on the Gymnasium floor? The analogy btwn email Spam and Standing Waves caught me off guard until the Incogni pitch began in earnest.

Good instructional vid. Worth watching.

Its interesting that this video starts out with how the chart was made (had to pause it at 52 seconds lol). The first smith chart I ever had I made in solidworks because I couldn't find any in vector format. Now I get to go un-pause and see how they did it.

Watched this yesterday. Excellent video. Not just Smith Charts but some good transmission line theory to learn also. Will probably watch at least once more.
