[GreenKeys] Long Frame Jacks and software tools (slightly off topic)

[Jeffrey D Angus]

Some time back, I'd mentioned long frame jacks with respect
to a project I'm working on.

Here's some "in the middle of it" pix of what I've been up to.

In essence, two separate headsets and two radios. Mix 'n Match.

And a special tip of the hat to Wayne, WB4OGM for locating
the .206" version for me in a surplus store.

Design and analysis software:
<http://www.logiccircuit.org/>
<http://www.linear.com/designtools/software/>

Both of these are excellent at what they do. And they're
both free. LT Spice is what I used in a previous discussion
about snubber circuits across selector magnets.

Schematic drawing and PC board layout:

I can't say enough about this, just the ability to draw clean
schematics is worth it. Placing parts on a PC Board layout
is just icing on the cake. Also, they will export both the
schematics and board layout into bitmap images. As well as
.dxf files for AutoCAD. Oh, and they will, for a price, make
the PC boards for you.

Of course, Autodesk's AutoCAD is a bit of a budget buster
at $4200.

There is an alternative, at least for printing the drawings.

Beg-ware, but it's still free and you can use the plot
settings to make a full scale drawing.

Obviously having too much fun here.
