It's much easier to use a Smith chart than to do the calculations


You don't need a Smith chart and you don't have to do the

calculations
either.

I still have a pad of Smith charts. I don't have Mathcad. I have the

same
attitude to this as I do to Morse, i.e. to each his own. I don't see
anything wrong in having test questions on either subject, as I think


people should know about them, I just don't think that there should

be a
test on copying code by ear.


.. . "Test questions on Morse"? . . "People should know about Morse"?
How many WPM izzat??

You obviously didn't spend much time cruising the link I posted. You
don't have to have Mathcad to solve transmission line problems to get
away from the primitive paper and pencil nonsense. There are freely
available Excel and Java routines which will do the job too.

Mathcad . . ah, yes . . If you do any engineering math which gets
complicated in Excel you need Mathcad Alun. I've been using it for
about ten years and it's become absolutely indispensible. Maybe only a
half hour after I first loaded and fired Mathcad up those ten years
ago and started messing with it I was running rapid-fire "what-if's" on
a double integral I'd dreamed up as an exercise. Very intuitive.
Otherwise I wouldn't be able to run it. Heh.

'Tis an incredible solver which has saved me hundreds of hours of grunt
number crunching (and curve plotting BS) labor both on and off the job.
Don't believe the prices for it you see floating around the Web. My
latest iteration is v.2000 Pro ($800) which I bought in a
shrink-wrapped package for $65 at a local computer show after it was
one version outdated.
