Walter:

I think I might be able to guess why---when I first attempted to use
one--I tore it up and said some angry words (darn right nasty I
suspect)... I was a bit slow catching on with the smith chart, I am sure
you all were much more gifted and speedier... grin

Warmest regards,
John

I can honestly say I've never used a Smith Chart in anger in the
whole
of my life.

Never had one in my possession for more than a minute just to inspect
it. Or by chance came across a condensed version in a book.

And I've worked on and with transmission lines from 0.1 Hz to 3000
MHz. At frequencies at which the Smith Chart is misleading and
useless.

I just didn't attend the same school as you lot.

It's habit forming like alcohol, tobacco and women. You can't think
straight without one in front of you. ;o)

But I do appreciate the love and respect you all have for it.

Reg, you've aroused my curiosity on three points:

Why would you use 'Smith Chart' and 'anger' in the same sentence?

Why are there any frequencies where the Smith Chart is misleading and
useless? Which frequencies are they?

How can you say the Smith Chart is misleading and useless if you've
never used one, and never inspected one for more than a minute?
