The toroids add no value. Install and cut to

Marker beacons are so strong that a wet string
will nearly suffice. Hook a 40' piece of 22AWG
wire into the antenna connector and tape it to
the inside of the fuselage in as "strung out
straight" as possible. But GPS offers better
identification of the markers. Many markers
are not being repaired as they crap out.

I just pulled up the current LOC-D approach chart.
GRIGG FM is still on the chart but seems to lack any information
identifying it as an intersection on the chart,
as do both SAMOS and BARET the IAF and FAF's.
However, lighting up my 480 sim, I find it is in the DB as an intersection.
I flew the approach a few months ago in a non-gps PA-22; and GRIGG

Good Morning Ron,
Glad to hear they found the parts! Took a couple of years though.
I have been trying to research the necessity of having a marker beacon
receiver and have been able to find very few places where it serves any purpose
at all. There are several that are colocated with an NDB or where a DME
distance can be used. Those approaches, generally localizer approaches, would
need one of the following to shoot the approach. A DME, ADF, marker beacon
receiver, IFR approved GPS, or a fix from a controller who is qualified to
give that RADAR fix.
They were removed as a requirement for ILS approaches several years ago.
Many are still in service, but they are no longer required to be used. It is
nice to be able to check the glide path intercept altitude at some sort of
fix, but such a requirement does not exist in the routine US regulatory
requirements. Some pilot examiners may not like it, but that is the way it
goes! <G>
It's kinda like timing an approach. Fun to see if an applicant does so, but
VERY rarely needed!
Happy Skies,
Old Bob

Good Evening Ron,
That particular approach was what got me interested in the current status
of marker beacons.
A few of years ago, I wanted to shoot that approach, but the marker beacon
was listed as being out of service so the minima was very high. I checked
with the local FEDS and was told that it was highly unlikely that the fan
marker would ever be returned to service as they were having trouble finding
parts for the repair.
I had an IFR approved GPS, but under the AIM interpretation of that time,
substitution of a GPS measurement was not approved. (That interpretation in
the AIM has since been changed) There was no intersection listed to be
used in place of the Fan Marker. I requested that an intersection be named so
that we could use that intersection in lieu of the fan marker. That
intersection was then designated so under the old AIM interpretation we could
use
the GPS in lieu of the fan marker. I asked whether or not a radar fix from
the tower could be used in lieu of the marker. I was told that such use was
dependent on whether or not the particular controller who was working that
position was radar qualified. The last statement was NOT agreed to by all
of the FEDs with whom I spoke.
The last time I was at KSEE was last spring for the Beechcraft Heritage
Museum spring board meeting and the fan marker was still inoperative, but
with the new intersection available, there was no question as to whether or
not the GPS could be used.
Is that marker beacon now back in service?
I would be very interested in any other example within the US National
Airspace System where a marker beacon is still required and a GPS cannot be
substituted. I think we can get such a situation rectified if we try. It
worked at your home drome! <G>

| Subject: | Balancing Cockpit Lights |
As I'm working through the schematics for my system, I've got
annunciator lights for a handful of different scenarios. Low Voltage,
Over Voltage, Flap Motor, etc.....
Some of lights are included as parts of a subkit (IE: Voltage Reg) while
others are built by me. I'm concerned that some lights will be brighter
than others and they will not be uniformly lit on the panel.
1) What's the process for balancing lights?
a. In-line resistors. Trial and Error until you find one you can
live with?
b. In-line Pots. You can adjust them individually behind the
panel?
c. Different light bulbs?
Also, I'd ultimately like to put all of the cockpit lighting behind a
single dimmer switch. I'm guessing that's accomplished by grounding all
the lights to (and through) a dimmer switch. Correct?
Thanks for the help. Have a happy and productive 2010.

THE VIRTUE OF SIMPLICITY
Parts left out cost nothing and cause no service problems. Parts left out also
can cause no emergencies or smoke in the cockpit. I believe that the first statement
was attributed to GMs Charles Boss Kettering. Henry Ford was a great
advocate of the value of simplicity too; whether it be in life, in work or in
play. If our missions often involve flying IFR at night, then a very good case
can be made for all the backups, added equipment and redundancy advocated in
this forum. What concerns me is that all the emergency procedures required
to take advantage of redundant systems must be committed to writing and to memory;
then must be tested, practiced and periodically rehearsed. With the increased
costs of flying, TRUE currency becomes even more elusive. During an emergency,
pilots rarely have time to look in their POH for emergency procedures;
you will not have time either. When the adrenalin and sweat is flowing and when
fear and tunnel vision sets in is not the time to begin learning emergency
procedures.
What is your plan to counter smoke in the cockpit? I have a plan. The FAA is
currently saying that you need one too.
If 99% of your planned missions are day VFR, think twice or 3 times, before going
overboard on adding overly complicated equipment and redundant backup systems,
much of which you barely understand. And dont forget that your airplane will
perform better with less weight.

I don't think 'balancing' is a concern. They are all 'on' or 'off' and will get
12 volts when 'on'.
I'm midway thru my dimming setup and it seems to me that I'll need 1 dimmer for
all my Honeywell switches and indicators, another for cockpit map lighting, and
I'm hoping only 1 for the various avionics that have dimmer functions. The
last case may be an issue but I hope not.

On my Cessna 172, the strobe lights caused "tick" sounds. It was
eliminated by placing a diode and then a large capacitor on the supply
line to the audio panel, which reduced the brief dips in power when
the strobe packs charged.
In my Tundra, I effectively have the same setup. I plan to put a
large capacitor on the essential bus, which is connected with a bridge
rectifier as in Z13/8.
However, my second radio is on my main bus. Should I stick a diode
and capacitor in its feed line after the fuse ? Or should I plan
instead to rectifiy any noise issues if I actually have them ? My
anti-collision lights will be LEDs, not strobes, but I tend to think
clean power is good power.

Dead on right! The simplest, lightest, and most profound
adaptations of legacy TC electrical systems to OBAM aircraft
was the conversion of an "avionics bus" to a "dual feed-path
endurance bus" and replacement of the vacuum pump with an
SD-8. This produced a system for less weight and several-fold
improvement in system reliability. In other words, Z-13/8
gives you system reliability of the system in a King Air but
with the addition of only one switch (S/B Alt Control).
Further, there are NO combinations of mis-positioned switches
that put the system at risk for exacerbating a failure event.
Any contemplated departure from Z-13/8 (or any other Z-figure)
should be evaluated for validity of design goals. I receive
many direct inquiries from folks who say they've read the book,
studied chapter 17 and then ask for an evaluation of their
particular recipe for success. The system generally consists
of cherry-picked features from the Z-figures stirred into their
personal desires/worries.
I have to remind folks that each Z-figure speaks to an
architecture crafted to a design goal. Further, each
drawing as-depicted has a high-order probability of
being the elegant solution for an electrical system in
one aircraft out of 99.9% of OBAM aircraft under
construction.
Adding switches, busses, back-ups to the back-ups and
similar exercises will generally have a poor return on
investment in complexity, weight, and cost-of-ownership.
It's relatively easy to add perceived "enhancements"
but with a risk of inserting new failure modes along
with the certainty of increasing weight, complexity
and cost of ownership. But as Jerry pointed out, ideas
that seem to add comfort for perceived concerns may
backfire by adding complexity that the pilot has to
sort out when things are NOT going well in the
cockpit.
I've written extensively about dark-n-stormy night
stories that offer little in the way of understanding
while generating new worries amongst those who
have the least understanding of how the system works.
So just a friendly heads-up for those working on
progressive evolution of the z-figures: If your
design goal is to embark upon a new expedition
into experimentation, you're certainly free to do
so. We are, after all building EXPERIMENTAL airplanes
. . . or are we?
On the other hand, if one desires to tap the collective
knowledge, understanding and willingness here on the
List to teach, then consider questioning any perceived
shortfall in the Z-figures before you spend a lot of
$time$ cutting and pasting. The majority of folks
on the List are interested in seeing just how FEW parts
we can assemble in the MOST elegant combination to
MAXIMIZE failure tolerance of your project's electrical
system.

List,
I'm finally closing in on completing my wiring diagram. I have the
basics roughed in but wanted to get some review on it and also ask some
specific questions about circuit protection:
1. Do my wire sizes look sane? I read though Bob's documentation on
wire sizes and I think I have it mostly figured out, but wanted to
double check.
Keep in mind that the "ratings" for how wire is used
in airplanes is conservative to the extreme. A wire
is not in danger of heating to copper-melting temperatures
should you exceed the "rating" by say TWICE or event 4X.
See: http://aeroelectric.com/Pictures/Wire/22AWG_20A.pdf
that 22AWG wire in the foreground has been carrying 20Amps
until the insulation temperature was seen to stabilize at
about 112C . . . the wires INSULATION is RATED for 150C.
So even at 4X the current we normally rate the wire for
in aircraft bundles, it's not in danger of smoking it's
insulation . . . and WAAaaaayyy too cold to melt the
wire.
Now, the voltage drop in this wire at 20A is terrible.
Unless the wire run were limited to a few inches, we'd
choose to upsize the wire if only for that reason.
2. I want to have an avionics master switch, but also an e-bus. Since
the only 3 things I'm running on my e-bus are avionics . . .
Why not simply add a switch in series with your
e-bus normal feed path diode and label it
"Avionics Master". Then ditch the avionics bus
and run your avionics of concern along with
endurance necessities from the e-bus.
I decided to
drive the ebus from the avionics bus though a diode. The goal is to be
able to turn on the avionics master, then the ebus alternate feed. If I
loose my master contactor or the avionics master switch, then my ebus
will continue to work. I think I have eliminated all single points of
failure while maintaining an avionics master. Can someone take a look
and make sure I'm not missing something obvious?
As suggested in my post of a few minutes ago, what operational
problems do you perceive with Z-11 as published?
3. My drawing is missing all of the circuit protection except for the
ANL, and 5 amp breaker for the field coil. I want to add breakers for
the rest, but I don't think I need a breaker for each device as that
will get real expensive.
As describe in
http://www.aeroelectric.com/articles/fuseorcb.html
http://www.aeroelectric.com/articles/fusvbkr2.html
Fuses are 1:1 interchangeable with breakers
for their intended purpose . . . keep
wires from burning and keep faults in one
feeder from propagating to other segments
of the whole system.
Why would you want one set of busses with
breakers and yet other busses with fuses?
Can I group up some of the lighting on a
single breaker? Also, what about using a breaker for the entire e-bus
then omitting the breakers for the devices on the ebus? The lines will
be real short and it eliminates the single point of failure (breaker.)
Also, what about fuselinks? I understand them to be like a fuse that
blows extremely slowly, but I'm not fully understanding when and where
to use them.
It's not clear that you've latched onto what
fuses and breakers are all about. I'll suggest
that you re-consider fuse blocks for ALL busses
and one fuse per accessory. Quick, light, easy
to install, and inexpensive.

It is my understanding that the purpose of the e-bus is to be able to
open the battery contactor and instantly have the system load drop to
whatever is on the e-bus making it easier and quicker for the pilot to
shed unneeded load in the event of an alternator failure.
To that end I put only required avionics on the e-bus and avionics that
I don't absolutely need to have on an avionics bus thinking that this
was in line with the design goals of using an e-bus.
>

I read the prior post and see your point about cut-and-pasting elements
of various diagrams together which results in a more complex electrical
system, but in the case of Z-13/8, the drawing lacks an avionics bus
which means that everything plugged into the e-bus or main bus will be
powered on when the master contactor closes, and will remain on while
the starter is operating.
My drawing mirrors Z-13/8 except for adding an avionics bus and a
switch, which adds complexity, but in return, my avionics can be powered
off during start, and turning off the avionics master but leaving the
e-bus on instantly sheds load that isn't absolutely necessary. This
change does not add a single point of failure for critical avionics,
however it does add a point of failure for non-critical avionics (switch.)
So my question is this: Given that simple is always
cheaper/lighter/more reliable, is it worth the weight/cost/complexity to
add a bus and a switch so that I can keep my avionics off during start,
and be able to instantly shed all non-critical loads? I thought it was,
but it seems like you disagree.
Also, what are others doing here? Are they simply using the built in
power switch to turn stuff off at start (if the component has a built in
switch.)

I know that fuses/breakers/fuselinks protect the wiring, what I was
missing was the part about problems with one component spreading to
others instead of being isolated. I think I will just get fuse blocks
per your recommendation for the reasons you mention, but also because
problems with a fuse can be remedied in the air quickly and easily.
Thanks again,

| Subject: | Re: Adding an antenna to improve on the ground reception? |
You could use an antenna switch (vhf) to choose/select top or bottom antenna. Check
with your local ham radio store, or do a "google" search for same. It would
add maybe a pound or two to your comm installation with the switch, extra cabling
and antenna.

| Subject: | Official AeroElectric-List FAQ (Frequently Asked Questions) |
Dear Listers,
Please read over the AeroElectric-List Frequently Asked Questions (FAQ) below.
The
complete AeroElectric-List FAQ including the Usage Guidelines can be found at the
following URL:
http://www.matronics.com/FAQs/AeroElectric-List.FAQ.html
Thank you,
Matt Dralle
Matronics Email List Administrator
[ Note: This FAQ was designed to be displayed with a fixed width font such as
Courier. Proportional fonts will cause display formatting errors. ]
This FAQ can also be viewed in HTML online at the following address:
http://www.matronics.com/FAQ/AeroElectric-List.htm
************************************************************
******* LIST POLICIES AND FREQUENTLY ASKED QUESTIONS *******
************************************************************
PLEASE READ. This document contains AeroElectric-List policies and information
for new and old subscribers. Understanding the AeroElectric-List policies will
minimize problems for the Administrator, and will help keep the AeroElectric-List
running smoothly for all of us.
******************************************
*** Quick Start Guide to List Features ***
******************************************
There are many features available on the Matronics Email Lists and each
one is described in detailed below. However, using the List Navigator
you can quickly access the complete set of features available for this
List. The List Navigator can be found at the following URL:
http://www.matronics.com/Navigator?AeroElectric-List
****************************************
*** How to Subscribe and Unsubscribe ***
****************************************
Simply go to the Web Page shown below and enter your email address and
select the List(s) that you wish to subscribe or unsubscribed from. You
may also use the handy "Find" function to determine the exact syntax of
your email address as it is subscribed to the List. Please see the
complete instructions at the top of the Web Page for more information.
The Subscribe/Unsubscribe web page is:
http://www.matronics.com/subscribe
Note that you will receive TWO conformation emails regarding your subsciption
process. The first verifies that your subscription/unsubsciption request
was received, and the second confirms that the process has been completed.
You should receive the first email within a few minutes of your request.
The second conformation will arrive in less than 24 hours. You cannot post
until you receive the second conformation email message.
*****************************
*** How to Post a Message ***
*****************************
Send an email message to:
aeroelectric-list@matronics.com
Your message will be redistributed to everyone currently subscribed
to the List.
*****************************************************
*** SPAM Fighter - You Must be Subscribed to Post ***
*****************************************************
When a new post is received by the system, the From: line of the message
is checked and compared against the current subscription list. If the
email address is found, the message is passed on to the List Processor.
If the email address isn't found in the current list of subscribers, it
is dumped. This serves to very effectively thwart 99% of the SPAM that
gets posted to the Lists.
Remember, however, that the syntax of your email address is very important
with regard to the configuration of your email application such as Outlook
or Eudora. For example, the following two email addresses may be
functionally equivalent, but only one would pass the Matronics Email SPAM
test depending on which was syntax was subscribed to the given List:
smith@machine.domain.com
smith@domain.com
Either email address syntax is alright, just be sure that you configure
your email application to match *exactly* the address you've subscibed to
the List.
**************************************
*** Enclosure Support on the Lists ***
**************************************
Limited posting of enclosures such as pictures, documents, and spreadsheets
is supported on the Lists. There are a number of restrictions, and these
are detailed below. Please abide by the rules put forth regarding the
content of enclosures.
These are some of the features and limits of enclosures on the Matronics
Lists:
1) Enclosures will only be posted to the Real Time version of the Lists.
2) Enclosures will NOT be included in the Daily Digest version of the Lists.
3) Enclosures WILL BE forwarded on to the BBS Forum Web site.
4) Enclosures will NOT be appended to the Archives.
5) Enclosures will NOT be available in the List Browse feature.
6) Only the following file types and extensions will be allowed:
bmp doc dwg dxf gif jpg pdf png txt xls
All other enclosures types will be rejected and email returned to
sender. The enclosure types listed above are relatively safe from
a virus standpoint and don't pose a particularly large security risk.
7) !! All incoming enclosures will be scanned for viruses prior to posting
to the List. This is done in real time and will not slow down
the process of posting the message !!
Here are some rules for posting enclosures. Failure to abide by these rules
could result in the removal of a subscriber's email address from the Lists.
1) Pay attention to what you are posting!! Make sure that the files
you are enclosing aren't HUGE (greater that 1MB). Remember that there
are still people checking they're email via dial up modem. If you post
30MB worth of pictures, you are placing an unnecessary burden on these
folks and the rest of us, for that matter.
2) SCALE YOUR PICTURES DOWN!!! I don't want to see huge 3000 x 2000
pictures getting posted that are 3 or 4MB each. This is just
unacceptable. Use a program such as Photoshop to scale the picture
down to something on the order of 800 x 600 and try to keep the
file size to less-than 200KB, preferably much less.
Microsoft has a really awesome utility available for free that allows
you to Right-Click on a picture in Explorer and automatically
scale it down and resave it. This is a great utility - get it, use it!
http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx
Look for the link "Image Resizer"
3) !! This would seem to go without saying, but I'll say it anyway. Do not
post anything that would be considered offensive by your grandmother.
And you know what I'm saying; I don't want to see anything even
questionable. !!
4) REMEMBER THIS: If you post a 1MB enclosure to a List with 1000 members
subscribed, your 1MB enclosure must be resent 1000 times amounting
to 1MB X 1000 = 1 Gigabyte of network traffic!! BE CAREFUL and
BE COURTEOUS!
Also see the section below on the Matronics Photo and File Share where
you can have your files and photos posted on the Matronics web server
for long time viewing and availability.
*******************
*** Digest Mode ***
*******************
Each day, starting at 12 midnight PST US, a new 'digest' will be started.
This digest will contain the same information that is currently appended
to the archive file. It has all of the headers except for the "From:"
and "Subject:" lines removed, and includes a message separator consisting
of a line of underscores.
Each day at 23:55 PST US, the day's messages as described above will be
combined and sent as a single message to everyone on the digest email list.
To subscribe to the digest list, use the same subscription web form
described above, and just select the Digest version of the List.
http://www.matronics.com/subscribe
Note that you *can* be subscribed to both the realtime and digest versions
of the List at the same time. This is perfectly acceptable.
Now some caveats:
* Messages sent to "aeroelectric-list-digest" will be forwarded to the standard
email list. In other words, you cannot post messages only to the
digest List.
* If you are subscribed to both the regular List and the digest List, you
will receive the realtime postings as well as the digest at the end of
the day.
* If you reply to the digest email, your message will be forwarded to the
normal list associated with the digest. Important Note: Please change
the subject line to reflect the topic of your response! Also, please
*do not include all or most of the digest in your reply*.
****************************
*** List Digest Browser ***
****************************
An archive of all the List Digests can be found online in either plain text
or HTML format. These archives contain the exact Digest that was posted to
the Digest email list on the given day. The Digest Archives can be found
at the following location:
http://www.matronics.com/digest
*****************************************
*** The "DO NOT ARCHIVE" Message Flag ***
*****************************************
At times, your message may concern something that is revelent only to a very
small number of persons or to a limited area, and you may not wish to archive
it. In such a case, simply put the following phrase anywhere in the
message:
do not archive
Your message will not be appended to the archive, but will be sent to List
email distribution as normal.
**********************************************
***** READ THIS - Automatic Unsubscribes *****
**********************************************
Note that if your email address begins to cause problems such as bounced
email, mailbox is filled, or any other errors, your address will be promptly
removed from the List. If you discover that you are no longer receiving
messages from the AeroElectric-List, go to the following Web page, and look
for your email address and a possible reason for your removal.
The Matronics Email List uses utility called the "Email Weasel" that
automatically looks though the day's bounced email for addresses that
caused problems due to common things like "user is unknown", "mailbox
full", etc. If the Email Weasel removes your email address from the
Lists you will find record of it at the following URL:
http://www.matronics.com/unsubscribed
If the problem listed on the web site above has been resolved, please feel
free to resubscribe to the Lists of your choice.

Recent messages posted to the AeroElectric-List are also made available on
the Web for realtime browsing. Seven days worth of back postings are
available with this feature. The messages can be sorted by Subject,
Author, Date, or Message Thread. The Realtime List Browser indexes are
updated twice per hour at xx:15 and xx:45. You can also reply to a message

*******************************************
*** Web Forums Bulletin Board Interface ***
*******************************************
A phpBB BBS web Forums front end is available for all AeroElectric-List content.
content. The Forums contain all of the same content available via the email
distribution and found on the various archive viewing formats such as the
List Browse, etc. Any posts on the web Forums will be cross posted to the
respective email List, and posts to the Email List will be cross posted to
the web Forums.
You may view all List content on the Forums without any special login.
If you wish to post a message via the Web Forum interface, however, you
will need to Register. This is a simple process that takes only a few
minutes. A link to the Registration page can be found at the top of the

*********************************
*** Matronics Email List Wiki ***
*********************************
In an attempt to make it easy to store and find structured and often accessed
information, Matronics has installed a Wiki at:
http://wiki.matronics.com
The Wiki allows individuals to create web pages to contain useful information
for other users of the mailing lists and web site. Unlike an ordinary web page
where the content needs to be submitted to Matronics for inclusion, the Wiki
permits the users to construct their own pages and have them visible immediately.
While constructing pages for the Wiki is not difficult, some may not be
comfortable building pages. In that case, simply prepare the text and any
images and email it to:
wiki-support@matronics.com
One of the volunteers on that list will take your submission and construct
a Wiki page for you.
Often someone produces a particularly useful posting in email one one of the
Lists that would be of general interest. In that case Matronics may take that
post and convert it into a Wiki page.
*********************

*** List Support Contributions ***
**********************************
The Matronics Lists are run *completely* through the support of it members.
You won't find any PopUpAds, flashing Banner ads, or any other form of
annoying commercialism on either the Email Messages or the List web pages
associated with the Matronics Email Lists. Every year during November
I run a low-key, low-pressure "Fund Raiser" where, throughout the month,
I ask List members to make a Contribution in any amount with which they
are comfortable.
I will often offer free gifts with certain contribution levels during the
Fund Raiser to increase the participation. The gifts are usually donated
by companies that are themselves List members.
Your Contributions go directly to supporting the operation of the Lists
including the high-speed, business-class Internet connection, server
system hardware and software upgrades, and to partially offset the many
many hours I spend running, maintaining, upgrading, and developing the
variety of services found here.
Generally Contributions range from $20 to $100 and are completely voluntary
and non-compulsory. I ask only that if person enjoys the Lists and obtains
value from them, that they make a Contribution of equal magnitude.
Contributions are accepted throughout the year, and if you've just
subscribed, feel free to make a Contribution when you've settled in.
The website for making SSL Secure Contributions is listed below. There are
a variety of payment methods including Visa and MasterCard, PayPal, and
sending a personal check.
If you enjoy and value the List, won't you make a Contribution today to
support its continued operation?

AeroElectric-List Usage Guidelines
******************************************************************************
The following details the official Usage Guidelines for the AeroElectric-List.
You are encouraged to read it carefully, and to abide by the rules therein.
Failure to use the AeroElectric-List in the manner described below may result
in the removal of the subscribers from the List.
AeroElectric-List Policy Statement
The purpose of the AeroElectric-List is to provide a forum of discussion for
things related to this particular discussion group. The List's goals
are to serve as an information resource to its members; to deliver
high-quality content; to provide moral support; to foster camaraderie
among its members; and to support safe operation. Reaching these goals
requires the participation and cooperation of each and every member of
the List. To this end, the following guidelines have been established:
- Please keep all posts related to the List at some level. Do not submit
posts concerning computer viruses, urban legends, random humor, long
lost buddies' phone numbers, etc. etc.
- THINK carefully before you write. Ask yourself if your post will be
relevant to everyone. If you have to wonder about that, DON'T send it.
- Remember that your post will be included for posterity in an archive
that is growing in size at an extraordinary rate. Try to be concise and
terse in your posts. Avoid overly wordy and lengthy posts and
responses.
- Keep your signature brief. Please include your name, email address,
aircraft type/tail number, and geographic location. A short line
about where you are in the building process is also nice. Avoid
bulky signatures with character graphics; they consume unnecessary
space in the archive.
- DON'T post requests to the List for information when that info is
easily obtainable from other widely available sources. Consult the
web page or FAQ first.
- If you want to respond to a post, DO keep the "Subject:" line of
your response the same as that of the original post. This makes it
easy to find threads in the archive.
- When responding, NEVER quote the *entire* original post in your
response. DO use lines from the original post to help "tune in" the
reader to the topic at hand, but be selective. The impact that
quoting the entire original post has on the size of the archive
can not be overstated!
- When the poster asks you to respond to him/her personally, DO NOT
then go ahead and reply to the List. Be aware that clicking the
"reply" button on your mail package does not necessarily send your
response to the original poster. You might have to actively address
your response with the original poster's email address.
- DO NOT use the List to respond to a post unless you have something
to add that is relevant and has a broad appeal. "Way to go!", "I
agree", and "Congratulations" are all responses that are better sent
to the original poster directly, rather than to the List at large.
- When responding to others' posts, avoid the feeling that you need to
comment on every last point in their posts, unless you can truly
contribute something valuable.
- Feel free to disagree with other viewpoints, BUT keep your tone
polite and respectful. Don't make snide comments, personally attack
other listers, or take the moral high ground on an obviously
controversial issue. This will only cause a pointless debate that
will hurt feelings, waste bandwidth and resolve nothing.
- Occasional posts by vendors or individuals who are regularly
subscribed to a given List are considered acceptable. Posts by
List members promoting their respective products or items for sale
should be of a friendly, informal nature, and should not resemble
a typical SPAM message. The List isn't about commercialism, but
is about sharing information and knowledge. This applies to
everyone, including those who provide products to the entire
community. Informal presentation and moderation should be the
operatives with respect to advertising on the Lists.
