==> PUBLIC SERVICE: HAMS CONTINUE TO SUPPORT RIM FIRE RESPONSE

With California's gigantic Rim Fire still raging, Amateur Radio
Emergency Service (ARES <http://www.arrl.org/ares>) and Radio Amateur
Civil Emergency Service (RACES <http://www.qsl.net/races/what.html>)
volunteers continued to assist local emergency managers and responding
agencies in filling communication gaps. Tuolumne County RACES
<http://lodelink.com/tcares/RACES.HTM> Radio Officer Phil Fish, WB6GGY,
told ARRL that with telephone circuits overloaded and cell service
spotty, ham radio is keeping the lines of communication open.
ARES-RACES members are helping to support communication between local
government and the American Red Cross shelter.

"They were just hungry for hams," Fish said of local emergency
management officials. "We've had a great response from the local ham
community." Volunteers, he said, have been putting in "some long days."

   Tuolumne County ARES EC Carl Croci, NI6Z, said volunteers from
Calaveras County ARES also have been pitching in. "We are still
staffing the Red Cross Shelter and the community information phone
lines with four ARES/RACES operators on the phones and two in the
shelters," Croci said August 28. "There are now there shelters open at
the Tuolumne County Fairgrounds, and the Red Cross is using FRS radios
between the shelters, so the shelter ops are also monitoring those
radios as well. The EchoLink <http://www.echolink.org/> system has seen
a decrease in traffic asking about friends and relatives." The Red
Cross is sheltering approximately 100 evacuees. Other ARES-RACES
volunteers have been helping to handle telephone traffic in the county
emergency operations center.

Fish has described the terrain in Tuolumne and Mariposa counties as
"very, very, very rugged."

According to the National Interagency Fire Center (NIFC
<http://www.nifc.gov/>), the Rim Fire as of August 29 covers nearly
192,500 acres, with nearly 8000 acres burned over in the past 24 hours.
The Rim Fire, 30 percent contained, has now has claimed more than 110
structures, and fighting it has cost more than $39 million. The NIFC
says the fire has been crowning. The communities of Tuolumne City,
Twain Harte, Long Barn, Pinecrest and the Hetch-Hetchy watershed are
threatened, as are power lines in the region. Evacuations and road and
area closures are in effect. Th Rim Fire is not expected to be fully
contained for another 10 days or so.

A series of time-lapse images <https://vimeo.com/73310936> has been
posted that offer a perspective of the Rim Fire's rapid growth.

==> HAM RADIO IN SPACE: "HAM VIDEO" TRANSMITTER IS NOW ABOARD THE ISS

A Japanese cargo spacecraft has delivered an Amateur Radio on the
International Space Station (ARISS <http://ariss.rac.ca/>) digital TV
transmitter to the ISS. The equipment arrived August 9 and is being
stored in the space station's Columbus module. Gear includes the
transmitter, power supply, NASA-provided Canon XF-305 camera, and
antenna cables, reports ARISS-Europe <http://www.ariss-eu.org/> Chair
Gaston Bertels, ON4WF, who says the DATV transmitter is being dubbed
"Ham Video."

   "Installation will be done by US astronaut Michael Hopkins, KF5LJG,
who has been trained for the commissioning of the Amateur Radio digital
video equipment," Bertels said in a report posted on the ARISS-EU
website <http://www.ariss-eu.org/>. Hopkins will be part of the ISS
crew increment heading to the station next month. The 10 W EIRP S-band
(2.4 GHz) Ham Video transmitter will use one of the L/S-band "patch"
antennas installed on the ISS' Columbus module.

Commissioning will involve a series of tests that will be performed
over the course of three or four orbits. Bertels says it's possible
that the transmitter will send a continuous signal between
commissioning steps, offering Amateur Radio ground stations a chance to
test and tune their receiving equipment. "The transmissions will be
performed in automatic mode, without requiring crew time," Bertels
said. "The camera, which runs on a battery, will not be used, and the
ground stations will receive a black image."

A preliminary "Experiment Sequence Test" (EST) is planned for August
28-29 involving ARISS ground station IK1SLD in Northern Italy. "IK1SLD,
an ARISS telebridge station often used for educational ARISS school
contacts on VHF, has been upgraded for S-band reception," Bertels
pointed out.

Italian manufacturer, Kayser Italia
<http://www.kayser.it/index.php/exploration-2/ham-tv> has delivered a
1.2 meter dish, a down converter and precision tracking motors, all
part of the ESA-funded equipment. "For the EST, the station will
receive a DATV signal from a local, low-power S-band test transmitter,"
said Bertels. The decoded signal will be streamed over the web to the
British Amateur Television Club <http://www.batc.org.uk/> server, to
which BATC has offered ARISS free access. ESA investigators will
evaluate reception via the streaming video. "The test transmissions at
IK1SLD will cover the different frequencies and symbol rates available
on the Ham Video transmitter," Bertels said.

Receiving the DATV signal will be the greater challenge, Bertels says.
"[D]ecoding should be possible for a ground station equipped with a 1.2
meter dish, when the ISS is within a range of about 800 to 1000 km," he
said in an overview paper <http://www.ariss-eu.org/HamTV.pdf> on the
project. This would limit the DATV reception window to about 3 or 4
minutes during a favorable pass. "ISS tracking will be far more
demanding than it is for receiving VHF signals," he added. According to
Bertels, Kayser Italia is to provide five ground stations in Europe.

Once the Ham Video transmitter becomes operational, it will be used for
ARISS educational contacts with schools in Europe. There are no
immediate plans to deploy downlink video for ARISS contacts with US
schools, in part because no North American ground stations have been
planned. Read more

==> EDUCATION: ARRL TAKES TECHNOLOGY TO THE CLASSROOM -- A DOZEN
TEACHERS AT A TIME

Through its Teachers Institutes the ARRL's Education & Technology
Program (ETP <http://www.arrl.org/education-technology-program>) has
been working for more than 10 years to promote the teaching of
technology. In a new teach-the-teachers twist, the program recently
sponsored a Teachers Institute on remote sensing and data gathering. At
the inaugural four-day session held in late July in Dayton, Ohio, 12
teachers explored the use of remote sensors for gathering data in
space, on Earth and beneath the sea.

   "Remote sensing allows us to reach inhospitable and inaccessible
portions of our environment for study," explained ETP Director, Mark
Spencer, WA8SME, who coached the Dayton workshop. Spencer pointed out
how the thread of remote sensing technology runs through all aspects of
basic electronics, the science of radio, and microcontroller
programming.

The Dayton Amateur Radio Association <http://www.w8bi.org/> -- which
sponsors the Dayton Hamvention <http://www.hamvention.org/>® -- funded
and hosted the TI seminar in its brand-new classroom. All participants
previously had attended an introductory Teachers Institute.

In the workshop, the teachers configured sensor packages for a
high-altitude balloon, a SeaPerch <http://www.seaperch.org/index>
underwater robot and a land-based Boe-Bot
<http://classic.parallax.com/go/boebot>. Spencer introduced Mars
Lander/Marine Amateur Radio Robotics Exploration Activity (MAREA
<http://www.arrl.org/marea>) concepts in his class. MAREA is a hands-on
learning activity designed to engage students in learning programming
skills for command and control of robots, using Amateur Radio packet as
the means of communication. Students in the workshop used APRS
<http://www.aprs.org/> to send commands to remote robots as well as via
the ham radio packet station aboard the International Space Station!

   Spencer wants to see more teachers incorporate science, technology,
engineering and mathematics -- or "STEM" -- education, so they can help
their students understand the concepts behind classroom demonstrations,
not just observe the end result. "Having students witness a balloon
launch is not STEM education," he says. "Having students learn about
and develop the sensors carried on the balloon, then participate in the
balloon launch and recovery and apply mathematics to give meaning to
the collected data to study the environment is STEM education," he
maintains. Teachers attending the Dayton session got the point.

"This was the most valuable workshop I have attended," one teacher
enthused. "It introduced the way STEM should be taught." Another
teacher, who will be designing and teaching a STEM class, feels the
workshop gave her a valuable head start.

"Career changing" was how middle school teacher Bill Richardson, N5VEI,
from Mississippi described the workshop. He said remotely controlling
the robots using XBee <http://www.digi.com/xbee/>® modules or via the
ISS offers "so many potential lessons that I am giddy about teaching
it." His school will begin teaching binary numbers, binary searches and
analog-to-digital conversion to eighth graders.

This seminar marked the first time MAREA concepts were taught in a
large group, Spencer said. A number of the teachers later expressed
interest in incorporating MAREA activities in their own classroom
lessons. Spencer also presented two new classroom resources for using
satellite telemetry data from experiments to be launched on the next
AMSAT Fox satellite, set to launch in 2014. These will help students
study satellite "wobble" and power regulation from solar panels.

==> YOUR LEAGUE: SHARE YOUR KNOWLEDGE AT THE ARRL CENTENNIAL CONVENTION

The ARRL has issued a call for papers and programs to include in its
planned extensive slate of ARRL Centennial Convention
<http://www.arrl.org/arrl-centennial-convention-2014> forums and
presentations. The convention will take place July 17-20, 2014, in
Hartford, Connecticut. Dan Henderson, N1ND, is the Centennial
Convention Programs and Forums Coordinator.

   "Since this is a once-in-a-lifetime event, we are looking for
programs with a 'Wow!' factor to match the Centennial theme," says
Henderson. "We want participants to leave forums saying, 'Wow! That
inspired me to stretch my horizons!'" Program organizers seek forum
topics in five broad categories:

- Technical innovations and advancements

- On-the-Air Operating Activities

- Club Growth and Development

- Public Service Communication

- Education and Training

Proposed programs should address not only current technology and
techniques, but innovations that are likely in the near future. Since
the Centennial Convention will attract a diverse audience, forums
should have broad appeal, although, Henderson says, organizers will
consider topics that target more specialized or niche interests.

Programs should be either 50 minutes or 110 minutes long, including
time for a question-and-answer period. The convention staff will
provide video and image projection systems as needed. Several selected
programs may be streamed live on the Internet for the benefit of those
unable to attend the convention in person.

Submit forum proposal outlines on the ARRL National Centennial
Convention web page
<http://www.arrl.org/arrl-centennial-convention-2014>. Complete all
fields in the "Program Presenter Proposal" form. The deadline to submit
proposals is October 31, 2013. Program organizers will review proposals
and render final decisions by December 31. Henderson expects to have
the Centennial Convention fleshed out by the end of March.

For more information visit the ARRL Centennial Convention Presentations
web page <http://www.arrl.org/convention-presentations> or contact
<n1nd at arrl.org> Dan Henderson, N1ND (860-594-0236).

==> EVENTS: LET THE WORLD DIGITAL ATV QSO PARTY BEGIN

DATV enthusiasts around the world will take part in the annual World
Digital ATV QSO Party August 30 and 31 through dedicated US repeaters,
some direct transmissions and even via Skype. The clearing house for
all transmissions will be the VK3RTV digital repeater in the Melbourne,
Australia, area, with Peter Cossins, VK3BFG, as anchor. All
transmissions will be streamed live <http://www.batc.tv/> via the
British Amateur TV Club website <http://www.batc.org.uk/>. The event
was first held in 2011 as part of the Amateur Radio Victoria
centennial.

   VK3BFG says ATVers should join the party personally with short
demonstrations or anything else that might be of interest. The World
Digital ATV QSO Party kicks off August 30 at 0930 UTC with check-ins by
Australian stations. External Skype stations should monitor the BATC
website and log into the Skype event station, "atvqsoparty." August 31
at 0100 UTC ATVers on the WR8ATV DATV repeater in Columbus, Ohio, will
be patched in, followed by the W6ATN Southern Californian ATV network,
at which time Ken, W6HHC, will update the DATV Express Project
<http://www.tapr.org/pdf/DCC2012-DATV-Express-ProjectTesting_G4GUO-W6HHC.pdf>.
US repeaters will have their own net control stations. -- Thanks to Jim
Linton, VK3PC/WIA

==> EVENTS: EMCOMM EAST CONFERENCE TO FEATURE ARRL COO WJ1B

   ARRL Chief Operating Officer Harold Kramer, WJ1B, a Boston Marathon
finish-line volunteer at the time the bombs exploded, will discuss his
experience at EmComm East, an ARRL-sanctioned Amateur Radio emergency
communication conference, September 29 in Rochester, New York.

The conference is aimed at radio amateurs involved in emergency,
disaster response and recovery communications. Participants can attend
training sessions on technical topics, learn from served agencies, and
interact with other operators from around the region.

Most presentation slots have been filled, but a few openings remain. If
interested, contact <info at emcommeast.org> EmComm East or visit the
conference website <http://www.emcommeast.org>. -- Thanks to Jeff
Wigal, WY7Q, via The ARES-E Letter

==> EVENTS: MAKE PLANS FOR PACIFICON 2013!

   The ARRL Pacific Division Convention -- Pacificon 2013
<http://www.PACIFICON.org> -- is October 11-13 at the Santa Clara,
California, Marriott. Registration
<http://www.pacificon.org/2013/#registration> is now underway.
Pacificon 2013 is sponsored by the Mount Diablo Amateur Radio Club
(MDARC <http://www.mdarc.org>). This year's program includes a broad
selection of presentations and forums covering topics of interest for
all segments of the Amateur Radio community, from youth education,
operating, public service, technical (SDRs, homebrewing and more),
DXCC, MARS, and license preparation and testing. The Saturday SDR forum
will include presenters from Elecraft and FlexRadio.

Among the featured presentations will be Friday's Antenna Seminar,
conducted by Paul Howes, WA6GYY, with an outstanding lineup of speakers
(there is a $15 charge, and Antenna Seminar tickets must be purchased
in advance). Pacificon 2013 is looking for additional forum presenters
<http://www.pacificon.org/2013/#cfp>.

For more information on Pacificon 2013, contact Misa Siemons, KJ6BUE,

Talk-in will be on 147.060 MHz+ (CTCSS 100 Hz).

==> REGULATORY: AUSTRALIA ENDS HIGHER POWER TRIAL FOR RADIO AMATEURS

The Australian Communications and Media Authority (ACMA
<http://www.acma.gov.au/>) has ended an 18-month trial
<http://engage.acma.gov.au/advanced-amateurs-to-trial-higher-power/>
that allowed participating Advanced licensees in that country to run up
to 1 kW on the HF bands. Advanced licensees Down Under are limited to
400 W PEP. ACMA reached its decision
<http://www.acma.gov.au/Industry/Spectrum/Acquire-a-licence/Apparatus-licences/trial-of-higher-transmitter-output-power-for-licensees-i-acma>
earlier this month following a detailed assessment begun last March.

   "After taking into consideration all the data obtained as part of
the assessment process, the ACMA is of the view that the arrangements
put in place for the trial should not continue," the regulatory agency
said in terminating the arrangement.

ACMA pointed out that slightly less than 3 percent of the 10,690
eligible licensees -- 297 in all -- took advantage of the trial.
Operators had to apply for permission to participate in the trial.

"Of the 297 that did obtain the authorization, the ACMA was advised by
some participants that they had not used higher power," the agency said
in its decision. ACMA said participant comments it received via the
Wireless Institute of Australia (WIA <http://www.wia.org.au/>)
indicated that the benefits of running higher power "were confined to
those respondents and do not demonstrate broader benefits to the wider
community."

ACMA also said some participants' knowledge and awareness of
Australia's RF exposure regulations "did not meet ACMA expectations."

ACMA said that while it's aware that some countries do permit higher
transmitter power output levels than Australia does, "these countries
are likely to have different and unique regulatory arrangements and
policy considerations." The regulatory agency said it must base its
decision "on the data collected during the assessment process and the
requirements of the domestic legislative environment." Authorization to
operate at higher power output expires August 31.

The WIA for some time has been pushing for higher power limits for
Advanced licensees, who feel the current 400 W power limit puts them at
a disadvantage, especially in contests, while other countries permit 1
kW or more. After the New Zealand Amateur Radio Transmitters (NZART
<http://www.nzart.org.nz/>) was able to convince regulators in that
country to raise the power limit on similar grounds, the WIA was
encouraged to again pursue the matter. After the WIA was informed of
ACMA's decision to end the trial, and, following talks, it was decided
that the ACMA would revisit the issue next year. -- ACMA, WIA, Jim
Linton VK3PC

==> ON THE WEB: VANITY HQ WEBSITE PULLS THE PLUG

After serving the US Amateur Radio community for 14 years Mike Carroll,
N4MC, has shut down his Vanity HQ <http://www.vanityhq.com/> website.

   "Vanity HQ is closed," now greets visitors to the site. "It's been a
good 14 years. Thank you everyone for participating, sending bug
reports and comments, and I especially thank all the Elmer volunteers
who have helped me over the years. It is time for me to move on.
Regards to all."

The site has had its ups and downs over its lifetime. Carroll made a
similar announcement in 2004, citing "a shift in my priorities," but
the site eventually remained open. Over the years Vanity HQ often was
the first stop for radio amateurs seeking a vanity call sign. Among
other information, it provided a list of recently issued vanity call
signs as well as available call signs and active vanity call sign
applications.

In 2008, the ARRL Board okayed a partnership with the Vanity HQ site to
have QST Silent Key listings included in the Vanity HQ history project
in an electronically searchable format.

After Carroll announced he was shutting down in 2004, Eldon Lewis,
K7LS, inaugurated his RadioQTH <http://www.radioqth.net/> website,
which offers essentially the same information Vanity HQ did.

==> SOLAR UPDATE

Intrepid Sun Watcher Tad Cook, Seattle, Washington, reports: Solar
activity slipped back again this week, with the average daily sunspot
number declining nearly 50 points to 77 and average daily solar flux by
nearly 10 points to 116.4.

   The latest prediction from NOAA/USAF has solar flux at 108 on August
29, 105, 100 and 105 on August 30 through September 1; 110 on September
