RE: Resistors

Ron D'Eau Claire-2
Huh??? I didn't say that!

The assembly instructions will teach anyone who has built an Elecraft rig
the color code. The correct colors are in each step right after the value
for the resistor, e.g. 4.7k  (yel-vio-red). By the time you're done
building, you know the color code!

A DMM doesn't hurt. Sometimes the colored resistors are hard to read
correctly, and some of the bands are so tiny on the smaller units that the
color is simply hard to see!

Re: Resistors

Maybe I missed it, but I didn't see anyone mention that the K2 resistors
are packed in the correct order from the "factory". Also being
color-blind, I never bothered to try to read the color codes. I just
grabbed the next one from the string of resistors, checked it with the
DVM, and installed it. It's been a couple of years now, but I seem to
recall the hardest part was finding which end of the string of resistors
to start from.

73's,

RE: Resistors

While true that the K2 does strip package the resistors in the proper
insertion order, several of the options package the resistors loose.
Knowing how to read the color code still comes in handy - but it gets easier
with practice, after 50 years of building, the values just pop into my head
when I see them - the problem is that the colors are not as clear and
distinct as they used to be.

Ever notice how many males are color blind?  I think the overall
percentage is something like 80% with some form of color vision defect.
I have nearly monochrome vision, but it's not a big disability at all:

1.  Two ties (1-stripes, 1-not stripes) work with any shirt.

2.  All shirts go with all pants.  Socks are either white or black.

3.  I only needed one dry-erase marker for the whiteboard in my office
when I still had an office.

4.  Monochrome monitors used to be cheaper than color monitors.

5.  In college in the early 60's, and working at the local TV station, I
never had to fix the color monitors because I never turned them on (the
rule was, "It dies on your shift -- you fix it")

6.  I can see in the dark way better than you can

#6 was a mixed bag.  While in Air Force Comm in SE Asia, they formed a
combat comm team out of color blind guys like me (yet another indication
that we're in the majority), sent us to jump school, and we got to do
nighttime airborne ops.  In fact, they never let us jump in daylight.

Thanks Elecraft for taping the K2 resistors in installation order since
there are a bunch of them in that kit.  I've also build a full KX1 and
the KAT2 in which the resistors were loose, but there weren't nearly as
many of them and I just measured each one, found it's value in the parts
list, and taped it to a paper in installation order.  That too had a
side benefit -- it made me read thru the manuals BEFORE turning on the
soldering iron, something I highly recommend even if you can tell amber
from yellow.

I will echo Ron's comment about the colors not being easily to sort out on
today's resistors.  It is much better to use a DMM to be sure, and not trust
your eyes.  If you want to pick resistors, do so with a high intensity light
and magnifier, and you will have a better chance of picking the correct one.
