<P class=subhead>NEW HF OPERATORS - THINGS TO DO
<P class=default>Two medium-to-low speed CW contests are on the calendar
- Labor Day Sprint and the Straight Key Party - along with the higher
speed NS Sprint that happens each Thursday evening and the really higher
speed North American CW Sprint on the evening of Saturday, Sep
7<SUP>th</SUP>. Think of these as aerobic classes for the CW operator.
Yes, you'll sweat, but it will be a good sweat!
<P class=subhead>BULLETINS
<P class=default>There are no bulletins in this issue.
<P class=subhead>BUSTED QSOS
<P class=default>Art W6XD spotted a typo in the previous issue's CQ WW
CW item in which the editor had "80" on his mind - the anniversary will
be the 90<SUP>th</SUP> of the first Transatlantic two-way amateur
contact. If any French or U.S. stations are interested in operating with
those historic call signs mentioned last time, please let your editor
know!

<P class=default>Don't look now but Tad K7RA has been bringing you the
<A title=http://arrl.org/w1aw-bulletins-archive-propagation
href="http://arrl.org/w1aw-bulletins-archive-propagation"
target=_blank>ARRL Propagation Bulletin</A> for 22 years now! As Tad was
quoted in ARLP033, "...your current author's stewardship of this
bulletin began in 1991, not because of any particular expertise
regarding astrophysics, but due to a similar sudden burst of solar
activity, which happened to coincide with the former (and only other)
author of this bulletin becoming too ill to write. The event was
Thursday, January 31, 1991 when the solar flux reached 357. Someone
needed to write about this. I had no idea when I alerted folks in
Newington that it would be me." Wow - an SFI of 357? That hasn't
happened lately...but I'm sure Tad would let us know if it did!

target=_blank>PhoneSats</A> that download messages via ham radio?
"Crowd-sourced" science via ham radio resulted in these CubeSats that
use a smartphone as their controllers. Practice in receiving these
packets is great for next year's Field Day bonus points...just sayin'.

<P class=default>Before you drive home after the contest, consider that
sleep deprivation makes for an impaired driver. If you've been awake for
18 hours, it's similar to having a blood alcohol content of 0.05 percent
-- perilously close to the legal limit in many states and not really a
good idea to be driving at that level no matter what the legalities may
be. A 24-hour period without sleep takes you to about 0.10 percent and
that <I>is</I> the legal limit in all states. Take a nap before heading
for home!

<P class=subhead>WORD TO THE WISE
<P class=default><B><I>Tag</I></B> - no, not "you're it!" but the
Cabrillo data element. When you see "Cabrillo tag", the reference is to
the line of information beginning with a word or words followed by a
colon (:) and then some alphanumeric characters. For example, the tag
containing your power level is "CATEGORY-POWER:" The "tag value" is
whatever information follows the colon until the end of the line marked
by a carriage return and line feed character (CR/LF). Continuing the
example, there are three recognized (legal) tag values for power; QRP,
LOW, and HIGH.<A name=toc03></A>

<DIV class=itemTitle>TECHNICAL TOPICS AND INFORMATION<A name=Tech
target=_blank></A></DIV>
<P class=default>Guy K2AV found a particularly interesting view of
propagation provided by the <A title=http://reversebeacon.net/
href="http://reversebeacon.net/" target=_blank>Reverse Beacon
Network</A> (RBN) watching a particular signal over an entire contest.
The results document the propagation modes changing, particularly if
conditions are quiet. He presents an example recorded during the 2011
ARRL DX CW contest on 40 meters when multi-multi stations were all
calling CQ consistently. Start by logging on to the <A
title=http://www.reversebeacon.net/analysis/
href="http://www.reversebeacon.net/analysis/" target=_blank>RBN's
analysis page</A>. "Enter 02/19/2011 as the date. Click on the Europe
bar. When the station selection expands, click on S5ØARX. Enter NY4A,
W3LPL, and K3LR under stations. Look at the 40 meter spots. On the right
side of the graph for the...day, Saturday evening was for propagation
one of those wide open very "smooth" propagation evenings analogous to
reflections off a lake on a windless day. In particular, starting around
19Z or so, see how NY4A's strength goes through three jumps up to a
plateau. You can see that LPL and LR climb them as well. These plateaus
follow the propagation changing modes (numbers of hops and angle) as the
band opens into the evening. Note that the NY4A 5-element long quad (at
84 feet center height, over 179 feet of catenary) engages all three
modes cleanly and fully as they open, without any fading. If the path to
EU from NY4A is cleanly open, the path must be open from LPL and LR
distances. By common expectation LPL and LR should have a propagation
advantage over NY4A. LPL and LR both have excellent stacked 3 or 4
element 40m Yagis. But note how as the fourth mode is engaged, both LR
and LPL fall off because they are not cleanly engaging the mode, most
likely because the increasing elevation angle is (moving) into a notch
in the Yagi vertical pattern. Also note that NY4A carries the best
signal for most of the 24 hours. This is an evaluation of the NY4A 40 EU
quad vs.known excellent installations that is hard to argue with."

St Charles County, MO. K-12 students are
welcome.</P></TD></TR></TBODY></TABLE>
<P class=default>Beginning with the editorial, "An Awesome Education" by
Jacob Ward, the discussion and articles address how students are
embracing the Do-It-Yourself (DIY) approach not only to hobbies but
learning in general. Columnist Erin Biba tackles the science classroom
with "Lab Is In Session" on how to more effectively teach science,
particularly the Next Generation Science Standards for K-12 students. A
series of short features ("Amazing Labs") highlights some of the cutting
edge lab environments in which science and engineering are getting done.
(Such as the Explosives Engineering course at my alma mater - I applied
for a spot like everybody else but like everybody else, didn't get
in...)
<P class=default>The centerpiece of the issue is the article "<A
title=http://www.popsci.com/technology/article/2013-08/short-circuit
href="http://www.popsci.com/technology/article/2013-08/short-circuit"
target=_blank>Short Circuit</A>" about Quin Entyre, a 12-year-old
electronics whiz who not only builds cool stuff using Arduino and other
technology, but runs a small electronics company and teaches the Arduino
to students up to several times his age. Early on, Quin has realized the
power of mentoring, suggesting that older kids could tutor and mentor
the younger kids, saying "It's fun to teach other kids, and little kids
look up to older kids."
<P class=default>The article also mentions Sylvia Todd, another
12-year-old maker (see her <A

target=_blank>FIRST Robotics Competition</A> which has provided
structure and focus for all sorts of technical activities on the part of
student teams at all educational levels.
<P class=default>Just last night at the St Charles Amateur Radio Club's
monthly meeting, Jacob KDØSJV, and his FIRST robotics team, the <A

City Channel Cats</A>, gave a great demonstration of their
Frisbee-flinging robot (it throws HARD!) and explained how FIRST works.
Jacob is an active new ham, studying for his Extra, and enthusiastically
explained how much overlap there is between robotics and ham radio -
electronics, programming, communication, building.

<P class=default>Nice, but what does this have to do with ham radio?
Well, everything, basically. As I am (overly) fond of repeating, "These
are our people!" Hands-on, multi-talented, informationally omnivorous --
that sounds like ham radio, where you can tinker away with everything
from electronics to woodworking to geophysics! All at the same time, of
course. Ham radio is an opportunity to learn that science and
engineering are much, much more than a collection of party tricks - and
so are robotics and microcontroller projects and hacking and making.
<P class=default>If we are going to interest these young minds in ham
radio, we're going to have to take ham radio to where they are. Ham
radio has to be an activity they can "own" by themselves without
requiring an adult to be constantly looking over their shoulders. I'll
be talking with Jacob and other young hams about hybrids of
Technician-level ham radio and robotics, for example. What local groups
-- young and old -- are available for <I>you </I>to support? Maybe
there's a "<A title=http://makerspace.com/ href="http://makerspace.com/"
target=_blank>maker space</A>" near you that could make use of your
wireless skills and know-how. Can you weld? How about leading a learn to
solder class? Show a group how much good stuff you can get out of
tearing down broken electronic gadgets. Trust me, ham radio will soon
enter the conversation and you won't have to be forcing it in there,
either.
<P class=default>Listen to what their interests are then go where the
audience is. Let them add ham radio to their toolbox on their own. It
won't do us any good to sit behind display tables with our arms folded,
expecting them to push their way into our groups and activities. Will it
be different? Of course, but then, ham radio was a different sort of
thing when you got started in it, right? Unfamiliarity is an
opportunity. Expand your comfort zone and you may be surprised at the
enthusiasm with which you -- and ham radio -- are greeted!
