Default N2PK's Vector Network Analyzer

If you missed it see:
http://users.adelphia.net/~n2pk/

I would like to build one so I asked on the
use net
http://groups.yahoo.com/group/N2PK-VNA/
if anyone had a parts kit.

The response I received to date has been
an offer for the PCB's and someone else
looking for a parts kit.

If there are a number of us, we would do best
with a group buy. If you have the desire to
build one and want to form a group let me know.

Please note the delete.this.
in my return email address.

Greg Ordy did both a kit offering and completed boards about a year ago. Not
sure if he has more planned or not- it was a labor of love.

Sorting components into kits is *always* a labor of love. I regularly
sort packages of about 1000 components into 10 kits of about 100 each,
and almost every component has to be individually sorted into trays and
repackaged by hand. Every hand movement takes time, and every second is
multiplied by some number between 10 and 1000. I dread to think what
kind of grunt-labor rate it's actually earning for me.

SMD components are even more difficult and time-consuming to handle,
re-package and re-label. Having built an N2PK analyzer, I wouldn't ever
consider sorting those parts into kits. It's actually easier to buy the
parts yourself, and keep them in the marked bags from Digi-Key or
Mouser.

N2PK provides a complete shopping list. For people outside of the USA,
there is more information on my 'In Practice' pages.

Don't worry that the minimum order quantities of Rs and Cs are 50 or
100. SMD components are cheaper than wire-ended - and when an 0805
resistor vanishes into hyperspace, you'll be glad you have some extra!
(Also ask yourself: how could a kit maker know which parts you're going
to lose?)

Above all: if you're really interested, join the Yahoo group.
