ChineseVOA Radiogram

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。

这是美国之音以MFSK32模式(多频移键控32波特)发射的信号。 多频移键控32 baud是业余无线电使用的流行模式
。我们现在试验通过短波信号发射机用该模式发射信号。

请将您的收听情况报告寄至 Chinese@voanews.com,请在您的回复电邮主题栏内写上“VOA Radiogram”作为您

The VOA Radiogram experiment enters a new phase with MFSK32 text included in the shortwave broadcasts of the VOA Mandarin Service.

Beginning today (Monday morning in China)...

There will be 1:10 (1 minute, 10 seconds) of MFSK32 in Chinese beginning at..

2258:15 UTC 6135 9845 kHz
and
0058:10 UTC 9880 15385 15565 17560 kHz

These transmissions will be daily and continue for about two weeks. The transmissions are via IBB relays stations in Asia.

毎週土曜日に放送されているVOAのFSK放送、テキストといくつかの画像が送られている。米国東海岸からの送信ということで日本での受信はかなり困難。それでもあれこれ工夫をして受信することは可能である。

DFSさんによれば、日本からの受信報告もいくらかあるようで、今回VOAの中国語の終了部分に70秒の中国語メッセージを挿入することになった。日本時間では7月28日朝になる。
0758JST 6135、9845
0958JST 9880、15385、15565、17560
しかし実際にはすべて強力なCNR1ジャミング放送に潰されておりFSK波がどこまで復調できるか受信しなければわからない。

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.

Свобода Интернета и национальная безопасность

Юлия Савченко
17.07.2014

Нейтральность сети и свободный Интернет – вот цель, достижение
которой администрация Оба>=e zat считает основной в сфере
коммуникационной политики. В частности, она поддерживает идею
Форума по управлению Интернетом – площадки, созданной в США для
обсуждения и формулирования проблем управления глобальной сетью.

В рамках этого форума в среду 16 июля в Вашингтоне состоялось
обсуждение проблемы, давно уже занимающей практиков и теоретиков
Интернета: кто и как должен регулировать глобальную сеть.

«Мы рассматриваем Интернет как территорию, открытую для
соревнования самых разных игроков», – подчеркнул участвовавший в
форуме заместитель министра торговли по коммуникациям и
информационной политике Лоуренс Стриклинг.

«Мы в США считаем, что здоровая конкуренция и участие в рÐ0 eeитии
Интернета всех участников коммуникационного процесса является тем
путем, по которому должны идти всемирная сеть в процессе своего
развития», – продолжал Стриклинг.

AIRのDRM放送はこのところテストの表示ではなくBangaloreと送信所が表示されている。7月8日も受信状態は良く、ほぼ100%の復調である。
キャリアーは1140前から出ておりISが流れている、1315番組終了まで信号の衰えもなく安定した受信状態が続いている。15795kHzの受信状態としては珍しいことだ。
