DRM短波デジタル放送の世界

予告されたようにVOAの中国語ではFSK波によるテキストメッセージが番組の最後にちょっとだけ流された。
28日2258と29日0058の2回、激しいCNR1ジャミング放送の中、ピロピロ音が出てきた。

2258の6135kHzはスーパージャミングでまったくNG。9845kHzも文字化けで判読困難。
0058と15385と21560kHzが比較的よく復調できた。15565kHzは文字化けが多すぎる。結果2波で復調できたのを合わせてほぼ送られてきた文字が判明した。
FSK波ということでAM放送の混信にもかなり強いことがわかる。このテスト放送は今日から2週間行われる予定。

以下、15385と21560kHzで復調できたVOA初の中国語によるテキストテストメッセージ。

Voice of Russia Shuts DC Bureau

VOA News
July 15, 2014

Facing legal problems, the Russian government-funded radio
network — the Voice of Russia — has fired its Washington bureau
staff and closed the office.

The shutdown happened July 14, amid allegations of tax fraud and
claims of racial discrimination at the network.

Alexei Iazlovsky, the head of the VOR's U.S. operations, pleaded
guilty last year to tax fraud and will be settþ later this year.

VOR's employment practices also have attracted attention from the
IRS and the Equal Employment Opportunity Commission.

The IRS is investigating whether VOR used contractors alongside
full-time, salaried employees to skirt payroll taxes. The Equal
Employment Opportunity Commission took an interest in VOR after
several former staffers claimed they were fired because of their race.

The employees have filed a lawsuit against International TV
Services, VOR's contract manager in the United States.

Some suspect Voice of Russia will quickly return to the U.S.
through a different management company without the legal troubles.

Earlier this year, the Russians stopped Voice of America
d Vadcasting in Moscow on AM radio.

Note from Kim: The Voice of Russia is the former Radio Moscow,
which broadcast in more languages, from more transmitters, than
any international radio station of the Cold War era. Voice of
Russia is still available in the Washington area, 24 hours a day,
leasing time on WZHF, 1390 kHz AM. With the VOR Washington studio
closed, all Voice of Russia programs now originate in Moscow. The
station usually identifies itself as "Radio VR."

Iranian Satellite Jamming Causes Storm Of Controversy

By Frud Bezhan
July 23, 2014

The Iranian regime has long used signal jamming to disrupt the
flow of information into the Islamic republic, but it couldn't
have forecast the strategy's deadly consequences.

Satellite-jamming technology is being blamed for disrupting
Iran's ability to predict a major dust storm that hit Tehran in
June, killing five people.

In a report presented to parliament this week, the Iran
Meteorological Organization claimed it was unable to forecast the
massive dust storm because of signals emitted by jamming devices,
according to the semiofficial ISNA news agency on July 22.

In addition to the five killed, the June 2 storm injured several
dozen people and knocked out power to around 50,000 homes in the
capital, according to Iranian media reports.

ISNA quoted Iran Meteorological Organization official Ahad
Vazifeh as saying that pertinent authorities had been warned of
the effect of jamming signals on meteorology forecasts before the
deadly storm hit Tehran.

Iran has been known to use jamming technology to prevent
satellite transmissions of foreign-based television and radio channels.

The government seems to intensify its jamming efforts during
sensitive times, such as the widespread protests that followed
Iran's 2009 presidential election, and the Arab Spring
revolutions.

Iranian officials have acknowledged that signal jamming takes
place, and have even warned of potentially negative consequences,
including health dangers posed by signal jamming.

In February, the Iranian Health Ministry set up a committee to
investigate whether the government's jamehltNgbeatellite signals
could pose a health risk to citizens.

Chicago's Argonne Lab Developing Battery of the Future

Kane Farabaugh
July 20, 2014

CHICAGO - In 2012, the Department of Energy's Office of Science
awarded a $120 million grant to a new technology center focused
on battery development - headquartered at Argonne National
Laboratory in suburban Chicago, Illinois. The Joint Center for
Energy Storage Research brings together scientists and engineers
from government, national laboratories, and industry to provide
them with the tools, funding, and space to make the next
technological breakthrough in energy storage.

Smaller. Lighter. Longer Lasting. That's what consumers want in
the batteries they use to power personal electronics.

At the Joint Center for Energy Storage Research, or J-CESR,
researchers hope to meet the demand.

This is the birthplace of the lithium ion battery technology, but
J-CESR scientists and engineers have bigger - and smaller - goals in mind.

"Five times the energy density at one fifth the cost." And all
this is five years, accrdoing to deputy director Jeffrey
Chamberlain. Cell phones, he says, are the devices where
consumers will first notice a change.

"So instead of charging it every day, they might be able to
charge it every few days or every week. Or instead of having
certain power and capability, they might be able to get to a kind
of power that might be unimagined," says he.

Chamberlain says the ultimate goal is to change the worldwide automotive market.

"The bigger mission we are on is trying to store energy in a way
that is cost-effective and safe so that we can compete directly
with the internal combustion engine using electricity or electric
transport," says Chamberlain.

Argonne's Energy Systems Division Director Don Hillebrand says
more power for personal electronics is an easy sell - but
consumers demand change when it comes to cars.

"Some consumers want an all-electric vehicle. The big debate
right now is how many of them are there? That number changes
based on how much gasoline costs. Really at what point does
gasoline get expensive enough that it drives more people into
wanting all-electrics?" – asks Hillebrand.

Hillebrand says the sales figures this year - about ten thousand
electric vehicles sold per month in the United States - is below
industry expectations, but the battery the center is developing
could change the picture.

"It's showing steady growth as we go forward. That number needs
to be ten times bigger for us to really say that this program has
been a success, and getting to that ten times is really tied to
getting the battery to what we need it to be," says Hillebrand.

But if that battery development is successful, and sales of
electric powered vehicles take off, there will be increased
demand on the existing power grid to recharge those batteries - a
problem the scientists and researchers at J-CESR are also
tackling by developing a large scale battery for the grid.

Ancient Subsurface Ocean Could Have Flowed on Pluto's Moon Charon

Matthew Hilburn
June 16, 2014 3:32 PM

Pluto's moon Charon may have once had subterranean oceans of
liquid water, something the U.S. space agency NASA hopes to
investigate further when its New Horizons spacecraft swings by
just over a year from now.

The notion that there could have been liquid water on a body 29
times further away from the sun than Earth seems far fetched
given the surface temperature on Charon is minus 229 Celsius, but
NASA scientists say that because the moon may have had an
"eccentric," or slightly oval-shaped orbit, Pluto's gravity may
have caused the interior of the moon to flex, causing enough heat
to melt ice.

This phenomenon is believed to be the reason for potential
subsurface oceans of liquid water on Jupiter's moon Europa and
Saturn's moon Enceladus.

NASA hopes New Horizons will be able to provide a detailed
analysis of crack patterns on Charon in order to see if there was
once water underneath the surface.

"Our model predicts different fracture patterns on the surface of
Charon depending on the thickness of its surface ice, the
structure of the moon's interior and how easily it deforms, and
how its orbit evolved," said Alyssa Rhoden of NASA's Goddard
Space Flight Center in Greenbelt, Maryland, in a statement. "By
comparing the actual New Horizons observations of Charon to the
various predictions, we can see what fits best and discover if
Charon could have had a subsurface ocean in its past, driven by
high eccentricity."

Charon is the largest moon in the solar system relative to its
planet (dwarf planet in Pluto's case), with one-eighth of Pluto's
mass. Scientists think it was formed after an impact on Pluto
caused debris to orbit and gather into several moons.

Researchers said that when Charon initially formed, the gravity
between the two bodies would have been enough to cause "their
surfaces to bulge toward each other, generating friction in their interiors."

"Depending on exactly how Charon's orbit evolved, particularly if
it went through a high-eccentricity phase, there may have been
enough heat from tidal deformation to maintain liquid water
beneath the surface of Charon for some time," said Rhoden. "Using
plausible interior structure models that include an ocean, lj sä hØt wouldn't have
taken much eccentricity to generate
surface fractures like we are seeing on Europa."

However, the days of liquid water on Charon, if they ever
existed, are long over.

The moon's orbit is now circular and slower, researchers said.
Plus, only one side of Charon faces Pluto. Together this would
mean that no significant gravitational tides would be generated
thus causing any would-be ocean to freeze.

Alan Stern, the principal investigator of NASA's New Horizons
mission and and a planetary scientist at the Southwest Research
Institute in Boulder, Colorado wrote in an email to VOA that the
study "shows just how exciting Pluto's moons could be."

"We're looking forward very much to exploring this planet and its
satellite system for the first time next year with New Horizons
to see what they are really like," he wrote.

Rhoden's research appears in the online journal Icarus.

Indonesian Smartphone Usage Surges but Still Lags

Alina Mahamel
June 16, 2014 3:41 PM

JAKARTA - A new Nielsen Survey Study reveals that smartphone
ownership continues to surge in Indonesia.

The survey shows smartphone ownership has risen up by 5 percent
over the previous year, according to Anil Anthony, Consumer
Insight executive director of Nielsen Indonesia.

"In urban Indonesia, the penetration of smartphones is 23
percent, which [means] one-in-four people has a smartphone," he
said. "That is quite low when we compare [it] with other
developing countries in Asia, but better than India and the Philippines."

The survey of 1,900 participants was conducted over the course of
2013 in several big cities, including Medan, Bandung, Surabaya,
and Makasar.

Uday Rayana, a communications observer in Jakarta, questions if
rising smartphone usage is a positive sign.

"Actually this is due to the smartphones spectacular growth which
now has become part of our lifestyle and in accordance with our
behavior of hanging out together and establishing communities,"
he said. "But the question is how productive are these kinds of
social media activities?"

Karania, a human resources professional staffer in a business
firm, told VOA that her smartphone has helped her in her job.

"When I have free time, I always spend it by using my phone", she
said, adding that most of her smartphone activities involve
chatting and browsing the Internet.

Meanwhile, Eggi, who lives in a Jakarta suburb and runs an online
food business, says his smartphone helps him interact with his customers.

"Mostly I use my smartphone for my business," he said.

According to the study, average Indonesian smartphone users spend
more than two hours daily on their phones, with most of the time
spent chatting, browsing or using Internet apps.

The Nielsen Survey states that, on average, women spend more time chatting than men.

The survey said young adults between 25-30 are the most active
smartphone users and spend most of their time talking on the phone.

The level of smartphone usage reaches its peak after office hours.

According to a Nielson report last year, usage varies wildly
between countries in East Asia. Some, such as Singapore and
Malaysia, have a smartphone penetration exceeding 80 percent,
while the Philippines stands at just 15 percent and India at 18
percent.

Designing for Disaster Helps Save Lives, Property

George Putic, KI4FNF
June 16, 2014

Natural disasters -- tornados, tauytÐaehsþu=nbQqu¾plndeoudUbeo§ ®1ccur frequeit
Wften unexpenu.lyfxfn¾c otatre, e' bgv ôcdtaTt6 (y h teo# ai ooperty and li
¹'ntnebtnioI fqoe p bnoRDtatMuseum showcases some of these technoloteees.

For example, large buildings and other structures can withstand
even strong earthquakes if they are built with some degree of flexibility.

"We need to let buildings move and we can actually understand
where they might fail and then go in and design buildings with
that in mind," said exhibition curator Chrysanthe Broikos.

The so-called ‘special moment frame,' allows a degree of movement
at points where large load-bearing beams join each other.

Rubberu; < Yn anvion blocks let buildings sway, while huge
shock absorbers dampen vibrations.

A model of the wind wall, built at the International Hurricane
Research Center, in Florida, shows how certain types of roofs are
more vulnerable than others to the strong winds of tornados and
hurricanes.

For example, a hipped roof shape withstands better than the flat
roof or the gableWotgkrding to Broikos.

In areas affected by strong winds, scientists also recommend
having at least one ‘safe room' where inhabitants can spend the
most dangerous part of the storm.

To keep storm surges in check, some communities along the U.S.
coasts and river banks built artificial reefs, using not just
rocks but also oyster shells, collected from restaurants.

"It turns out that oyst¿ efs actually help to attenuate wave
action," said Broikos. "They also help with soil erosion."

Broikos also says building parks along the shoreline, instead of
houses, is more natural and keeps valuable property away from danger.

As for forest fires, scientists now recommend that a so-called
home ignition zone be about 60 meters wide.

"What that means is trying to keep that area free of material
that easily combusts," Broikos said.

Some natural disasters cannot be prevented but researchers say
advance planning and timely investment can provide the same sort
of protection as applying sunblock lotion before going to the beach.

Egypt Releases One Al Jazeera Reporter

VOA News
June 17, 2014 4:52 PM

An Al Jazeera Arabic reporter was released from an Egyptian
prison Tuesday, 10 months after being arrested and held without
charge in a case that prompted serious criticism of Egypt's
military-led government.

The Qatar-based satellite channel said Abdullah Elshamy was
transÜ evt a Cairo policee2eafter being set free from
the notorious, high-security Scorpion prison.

Egypt's prosecutor general on Monday had ordered his release,
citing "health conditions."

The 26-year-old was met by his mother, wife and brothers as he
walked out of the police station in a northern Cairo suburb, The
Associated Press reported. Witnesses say the once robust Elshamy
looked frail as he exited the facility.

"The appeal which was accepted by the public prosecution was
based on the fact that Abdullah was carrying out his duties as a
correspondent for Al Jazeera at the time of his arrest," an Al
Jazeera lawyer Shaaban Saeed said.

Elshamy was arrested on August 14, 2013, while reporting the
police dispersal of sit-in protest in Cairo. In January, he went
on hunger strike to protest his detention.

His arrest coincided with a wide crackdown on Islamist supporters
of President Mohammed Morsi, who was overthrown by the military last year.

Egyptian officials have accused the channel of supporting the
Muslim Brotherhood, an organization and political party that has
been labeled a terrorist organization by the Egyptian
government. The network has denied the allegations.

Al-Jazeera calls Elshamy's freedom a relief rather than a cause
for celebration. It says he has been through a terrible ordeal,
and it thanked all who supported Elshamy, including the White
House and European Union.

Al-Jazeera is demanding that Egypt free three English language
journalists who remain jailed for allegedly spreading false news
- Peter Greste, Baher Mohamed and Mohamed Fahmy.

Some information for this report comes from AP, AFP and Reuters.
