Bob,
I have not visited your Aeroelectric Website much recently, so I may be way
behind the times but, I just noticed the Top Aviation Website Award on
Aeroelectric, and wanted to offer my congratulations on a job well done.
I have used the site in the past on numerous occasions and have found a
wealth of information to solve problems, answer questions, and in some
instances, just general knowledge enhancement.
Keep up the good work! It is so much appreciated!!
Roger

Let's try this from a different angle: How conductive is an Alodined surface?

| Subject: | Red Dot SWR Meter |
Bob,
During a previous discussion on this forum, we were kicking around the
relative use and accuracy of the small Red Dot SWR meter. You purchased
one
and performed some comparison tests with your lab equipment. I
purchased
this unit from you, at a good price, I might add, and will be using it
shortly to test the built in antennas in my nearly completed wooden
airplane.
Have you published the results of your testing of this meter with your
reference? It would be interesting to note the actual tested accuracy
of
this device.
Thanks,
Roger

Good question. There are descriptions of the process at:
http://tinyurl.com/7odr8ay
http://tinyurl.com/7sn63nx
Others have wondered about the conductivity of the process . . .
http://tinyurl.com/83qsqhe
http://tinyurl.com/74f759b
here's an excerpt from a book where the relative
conductivity of surface coatings are being examined
for use on antenna reflectors . . . though I'm not
sure if there's a direct correlation between
effectiveness as a reflector and conductor of DC
http://tinyurl.com/83pnyn7
This page speaks to the use of chromate coatings thusly:
http://tinyurl.com/7n3rx7n
Based on the product series, Buckeye uses the following undercoats
to protect your investment:
[]
Alodine: Yellow and Clear. Primary functions are for paint
adherence, rust inhibiting, and conductivity.
Anodize: Clear and Blue. Primary functions are for cosmetic
appearance, hardness, and rust inhibiting.
Zinc Chromate: Yellow, Clear, and Black. Primary functions are for
conductivity and rust inhibiting
Don't have time to delve into it deeply right
now but I'll invite interested individuals to
Google "chromate" and "conductivity" for some
sense of magnitude of conductivity effects on
bare metals.
I used to know some folks in the Process Lab at
HBC. If they're still there, I might be able to
get a 'numbers' dump on the topic.

I did a mini-review here on the List when the
unit I ordered arrived. I don't recall the exact
details but I was favorably impressed with its
performance as compared to the Bird and Measurements
Corp instruments I have here.
Nothing real quantitative. I recall that there were
differences at some frequencies and power levels on
the order of 10% . . . but in the field of RF power
measurement tolerances of plus or minus 10% is
pretty good.
I'm still hoping that I have a chance to participate
in some activities that will take me back inside the
walls of NIAR at WSU. If this happens, I think I can
get access to the EMC labs for a quick looksee at
the HID lamp assemblies on my bench for conducted
and radiated emissions. If those programs spool up,
I'll pick up another Red Dot to evaluate over a wider
range of frequencies and power levels than I can
generate here.
Given the instruments compact size and relative
robustness of enclosure and inspection of
the interior, I think the Red Dot SWR meter is a
great value.

| Subject: | Removing contacts from a King radio connector |
I'm about to upgrade one of my radios and need to extract some contacts
from my PS Engineering audio panel, which uses King connectors. I have a
King radio (KLX-135A) which shows a contactor extraction tool Part No
047-05099-0001, which looks like a straight forward thin screw driver
type tool. Rather than try to find one to buy, can anyone post the
dimensions so I can make one?
Regards, Peter

The working blade is 10mm long, 1.5mm wide and 0.65mm thick on a "handle"
5mm wide and 67mm long, same thickness
Best Regards

It's a VERY thin 'screwdriver'.
Here is a link to a source:

You can also buy the pins and the connector bodies from them.
