Smith Chart

Made a Smith chart for the spire cas ii. A work in progress......

Nice use of Turtle!

The black dot looks like 100 +j*50_omega per the curvy coordinate system...?

How about being able to move the black dot?

See attached for a draft routine to move a point with the mouse. Moving it on top of the graphics can get tricky: try using a background image instead (see ti_image).

Regards,

The real axis is a normalized axis.Z0 = 50 Ohm so 1.00 times 50 ohm = 50 ohm. In the file is a possibility to plot a list of impedances, the dot is just one example. I hope you understand because this is an engineer thing (actually much used bij ham radio operators).

Thanks for the explanation!
