==>  + PUBLIC SERVICE: SKYWARN RECOGNITION DAY SET FOR DECEMBER 4

    The 12th Annual SKYWARN Recognition Day (SRD) Special Event will
take place Saturday, December 4, 2010. SRD is co-sponsored by the ARRL
and the National Weather Service as a way to recognize the commitment
made by Amateur Radio operators in helping to keep their communities
safe. According to SRD Coordinator David Floyd, N5DBZ, Amateur Radio
operators can visit their local participating NWS office, working as a
team to contact other hams across the world throughout the 24 hour
event.

Floyd said that as SKYWARN Recognition Day has grown throughout the
years, he has seen a greater use of digital communications in addition
to SSB, CW, RTTY and packet radio: "Each year, more and more contacts
are being made using EchoLink, Winlink and the use of e-mail
reflectors." In keeping with the NWS setting, stations are asked to
include a weather report for their location in their exchange. The 2010
SKYWARN Recognition Day will be held on December 4 from 0000 UTC-2400
UTC. Read more here

==>  HINTS&  KINKS: SEALING PL-259 UHF PLUGS AND SO-239 UHF CONNECTORS

Don Dorward, VA3DDN, of Pickering, Ontario, sent us this idea for seals
for PL-259/SO-239 connectors . Contact Don via e-mail<va3ddn at arrl.net>
for more information.

The popular and low-cost PL-259 UHF plug and its mating SO-239 UHF
connector were never designed to be waterproof. In spite of this, many
of us find ourselves having to use these connectors out-of-doors for an
antenna or cable connection and then have the experience of trying to
apply some form of weatherproofing.

If this is not done, and done well, then intermittent connections soon
result, especially with wet freezing and thawing conditions, resulting
in moisture and corrosion getting into the connectors and even into the
coax itself.

    One well-known solution is to use a bondable rubber tape wrapping.
That often seems to work using one of the soft, moldable, stretchable
tapes that are available for the purpose. In practice, I have found
that the hardest area to seal effectively using this method is the area
from the rim of the male PL-259 shell to the mating SO-239 socket face.
This is especially true when the SO-239 socket is located partially
inside the cowl of the antenna mount (such as the Solarcon/Antron
vertical or other similar types) and it is impossible to get sealing
tape up into this tight location.

To overcome this problem, simply slip as many tight fitting O-ring(s)
over the SO-239 barrel (see Figure) as needed to fill the space between
the base of the SO-239 and the coupling ring. Lubricate the O-rings
with a generous amount of silicone grease, often sold in the automotive
part stores as "dielectric tune-up grease."

Important: Check that when the mating PL-259 plug is installed and
tightened down, the outer rim of the PL-259 shell butts up against and
slightly compresses the "O"-ring(s). The "O"-rings I used were ones I
had on hand, about 9/16 inch ID × 0.10 inch thick. I am sure anything
that's a snug fit will work. Of course, you will still need to wrap the
lower half of the PL-259 shell and the spot where the coax exits the
connector with tape to seal that part.

Do you have an idea or a simple project that has improved your
operating? Maybe you've taken something commonly found around the home
and developed a ham radio use for it? Why not share your hints with
fellow hams in "Hints and Kinks," a monthly column in  QST. If we
publish your hint, you will receive $20. Send your hints via e-mail to
h&k(at)arrl(dot)org or to ARRL Headquarters, Attn: "Hints and Kinks,"
225 Main St, Newington, CT 06111. Please include your name, call sign,
complete mailing address, daytime telephone number and e-mail address.

==>  ARRL PUBLICATIONS: ARRL INTRODUCES EXAM REVIEW SOFTWARE FOR HAM
RADIO LICENSING

    ARRL announced today that it will begin including practice
examination software with all of its popular license manuals. "The
first book to include the new bundled-in software is The ARRL Ham Radio
License Manual -- used by tens of thousands of prospective hams as
their first introduction to Amateur Radio," said ARRL Marketing Manager
Bob Inderbitzen, NQ1R. "The book includes everything to prepare for a
'first' ham radio license -- the Technician class license. A CD-ROM
tucked into the back of the book contains the new software, which we've
named ARRL Exam Review. The software includes the complete examination
question pool, plus short explanations of every question to help make
sure you understand the answer." Read more here

==>  + NEW QUICKSTATS POLL NOW AVAILABLE ON ARRL WEB SITE

Three new poll questions have just been published on the QuickStats
page<http://www.arrl.org/quickstats>  on the ARRL Web site. Let your
voice be heard!

Questions in this month's QuickStats poll include:

- From an operator's point of view, have modern Amateur Radio
transceivers become too complex?
- Looking back over the last several years, do you think the amount of
time you spend on the air has increased or decreased?
- Which social media platforms do you use most often?

Visit the QuickStats page<http://www.arrl.org/quickstats>  and be sure
to bookmark it in your browser. Results from this QuickStats poll will
be published in the February QST QuickStats page, located in the rear
advertising section. Along with monthly poll results, QST QuickStats
offers colorful charts and graphs that highlight interesting Amateur
Radio statistics.

==>  + ARRL TO CLOSE IN OBSERVANCE OF THANKSGIVING HOLIDAY

    ARRL Headquarters will be closed November 25 and 26 in observance of
Thanksgiving. There will be no W1AW bulletins or code practice

<http://www.dailymotion.com/video/xret4_eagles-desperado_life>" Cook,
K7RA, reports: Five new sunspot groups appeared in the past eight days,
and the average daily sunspot number for the November 11-17 period rose
