Het gemakkelijkst is het om FL-Digi hiervoor te gebruiken, die kan de MSG/MODE ID namelijk uitlezen en dan direct in de juiste mode over gaan.

[PA3RIS]

Ik heb dit vanmorgen maar eens geprobeerd, maar ik ontving helaas niets. Om 17.00 nog maar eens proberen.

Iemand hier die deze uitzendingen wel ontvangen heeft?

[PA3RIS]

De uitzending van vanavond op 17860 kHz was redelijk te nemen.. Ik heb hem zo'n 20 minuten goed mee kunnen schrijven.

[PA3RIS]

Vanavond helemaal goed ontvangen.
De uitzending is vrijwel helemaal in MFSK-32 en de modes staan nog in de tekst.

Ontvangen op 15670 kHz op een Yaesu FRG-8800 met een 2x 20 meter dipool.

Building Plans for Wiki-Style House Available Online
George Putic
January 13, 2Ø15
About one third of the world's city dwellers live in substandard
housing, according to the McKinsey Global Institute. But
researchers say free plans now available online for building
houses made of manufactured parts that perfectly fit together may
help solve this problem.
The world population is expected to grow to more than 8 billion
by 2Ø3Ø, and the housing situation in urban centers is already a
huge problem. Building new homes the traditional way still takes
weeks or months.
In a London neighborhood, a group of volunteers is constructing a
house made of prefabricated plywood panels and parts, the
so-called Wiki House. All parts were precisely cut in a Computer
Numerical Control, or CNC machine, following a free plan
downloaded from the Internet.
Co-founder of the U.K.-based WikiHouse Foundation, architectural
designer Alastair Parvin, said this could be the solution for
affordable housing.
WikiHouse is essentially a series of technologies we're
developing aimed at massively simplifying the process of making
really sustainable high performance houses to a point where
almost anyone can do it," he said. "And to do that we're using
the power of the web and digital manufacturing technologies like
3-D printing."
Precise cutting allows a perfect fit for all parts, which speeds
up the process of assembly. No special tools are required.
The Wiki House was built in 1Ø days for exhibition purposes.
Then, it was taken apart and reassembled elsewhere for permanent
use.
Parvin said the whole concept is based on the blueprints
available online.
"Open-source software is now really established, it drives a lot
of the software we use," he said. "What's happening now is that
that's now coming into the world of physical things, so we're
effectively building a kind of Wikipedia for physical stuff."
Parvin said the project is in its early stages, with limited
availability. But he said he expects it to grow as more people
start showing interest in houses whose assembly requires no
special skills.

Taiwan Protests China's New Air Routes Amid Rising Tensions
Ralph Jennings
January 14, 2Ø15
TAIPEI - Taiwanese authorities are protesting political rival
China's announcement that it is creating four new civilian air
routes that would conflict with Taiwan's own. The complaint
against Beijing comes amid growing tensions in overall relations
despite a six-year thaw under conciliatory Taiwan President Ma
Ying-jeou.
China told the United Nations' International Civil Aviation
Organization this week that beginning in March it would open four
new flight paths over the ocean strait that divides it from
Taiwan.
Officials in Taipei have protested since Tuesday, saying the new
paths conflict with its existing flight routes near the main
island and two groups of outlying islets.
Taiwan Civil Aeronautics Administration Director General Jean
Chen told a news conference she expected China to negotiate
further with her government.
She said when establishing a new flight path, a country needs to
negotiate and communicate with neighboring governments. She hopes
Taiwan can follow up with continued talks with mainland China
about the situation. As it is, she said, Taiwan cannot accept it.
The aviation agency fears that one new route will threaten the
safety of air traffic near Taipei, while the other three will
interfere with flights from Taiwan to the Kinmen and Matsu
outlying island chains. Taiwanese airlines and the air force have
indicated no immediate plans to make changes following China's
announcement.
Political observers say Taiwan will make more protests like this
in 2Ø15 to resist China due to increasingly vocal public
resentment.
China has claimed sovereignty over self-ruled Taiwan since the
Chinese civil war of the 194Øs, keeping the strait between them
heavily militarized. Since President Ma Ying-jeou took office in
Taiwan in 2ØØ8, the two sides have eased tensions and opened
talks leading to 21 economic agreements.
But the ruling Nationalist Party took heat from the public last
year for growing too friendly with Beijing and it faces a tough
presidential race next year against an opposition that advocates
more cautious China relations. Some Taiwanese worry that China
will eventually try to use economic links to bring the island
under Beijing's rule.
China's government agency in charge of relations with Taiwan said
Wednesday it had already discussed the new flight paths with
Taipei. It asked Taiwan to be more understanding and less
worried. The Chinese side says the new routes would ease today's
domestic flight congestion between Shanghai and airports in the
heavily populated region north of Hong Kong.

Facebook Launches Mobile App Offering Free Intey? in Colombia
Reuters via voanews.com
January 14, 2Ø15
BOGOTA - Facebook Inc on Wednesday launched a mobile phone
application that gives Colombian users free access to a handful
of online services, broadening Chief Executive Officer Mark
Zuckerberg's effort to boost Internet usage in developing
markets.
Colombia is the first nation in Latin America to receive the new
Internet.org service, in partnership with local mobile phone
provider Tigo, but the aim is to push the application across the
region.
The tools offered by the service provide a foundation Colombians
can use to "build their own prosperity" Zuckerberg said at a
presentation in Bogota with President Juan Manuel Santos.
"By giving people these basic tools for free, you're creating an
equal playing field," Zuckerberg said, referring to entrepreneurs
who could use the free Internet to start or grow a business.
Internet.org will offer more than a dozen services via the
Android operating system, including online encyclopedia
Wikipedia, weather websites, job listings and health information,
as well as Facebook's own social network and messaging serviBº
Access to the application's services is free, but links that lead
to information on other websites will require users to pay data
charges.
The service may even aid the country as it seeks an end to 5Ø
years of war with Marxist rebels, Zuckerberg said.
"Just giving people the tools of connectivity is important by
itself in creating communication and a tighter social fabric in
creating peace," the 3Ø-year-old CEO said.
The service, first launched in Zambia back in July, will
eventually be available via other mobile providers.
Facebook has partnered with more than 15Ø wireless providers over
the past four years to offer free or discounted access to its
social network, but the new app is the first time the company has
added services beyond its own website.
"Our obsession is how we can use technology to reach our big
goals, first peace, which will allow us more equality and better
education," Santos said.
While 85 percent of the global population lives in areas with
mobile phone coverage, only 3Ø percent have access to the
Internet, according to Tigo. Around 3 billion people will have
online access by the end of 2Ø14, the International
Telecommunications Union (ITU) has said.
Facebook hopes the Internet.org project will help more than 4
billion Internet-less people worldwide, many of whom live in
Africa and India.
The initiative has the potential to boost the size of Facebook's
audience, which totals 1.32 billion monthly users. Tigo, a unit
of Millicom, has about 8 million users in Colombia.

US Proposes Sharp Cut in Methane Emissions
VOA News
January 14, 2Ø15
The Obama administration is proposing a requirement to force the
energy industry ut dangerous methane emissions nearly in half
over the next decade.
The White House said Wednesday it will offer rules under the
country's clean air law in the coming months that would trim the
emissions by 4Ø to 45 percent below their 2Ø12 level.
Methane emissions are only a small part - perhaps two percent -
of U.S. greenhouse gas emissions threatening the world's climate.
But methane is more potent than carbon dioxide in trapping heat
in the atmosphere.
The United States is now the world's biggest oil and natural gas
producer. The White House said the methane emissioave been
cut from 199Ø levels. But it said the emissions would increase by
25 percent by 2Ø25 if new restrictions are not impo
The new rules, which would take effect in 2Ø16 before President
Barack Obama's e House term ends, would cover new drilling
equipment and old and new production located on public lands.
But thousands of existing wells owned by private companies would
be exempt.
Obama, a Democrat, in recent months has proposed numerous new
environmental regulations that have often drawn protests from
Republican lawmakers in Congress, the energy industry and
business interests. They say the rules are not needed, are too
costly to implement and an over-reach by Obama's use of executive
authority.
An industry group, the American Petroleum Institute, said
Wednesday the proposed methane regulations could hinder the
country's advance as a major world oil and gas producer and that
thdustry had already cut the emissions signifi

RSID:THOR 16 f=15Ø7Hz n?l t
Thank you for decoding the modes on VOA Radiogram.

[PA3RIS]

Hello friends,

Many of you have had problems with the Fldigi RxID. It correctly identifies the MFSK32 mode, but sets the audio frequency to somewhere between 1100 and 1200 Hz rather than the actual 1500 Hz center frequency.

I've noticed this phenomenon for over a year, but it might be more prevalent in newer versions of Fldigi.

If you are receiving a strong signal from the North Carolina transmitter, there is often a "halo" above and below the 500-Hz-wide trace of the MFSK32 signal. You can see this in a screenshot sent by Jonathan in Ontario ...



I think the Fldigi RxID latches on to the first thing it encounters that looks like an RSID, which would be the halo to the left (lower in frequency) of the actual MFSK32 signal. That halo is enough to activate the RxID, but not enough to receive actual text.

One solution might be to use an attenuator. Another solution is, in Fldigi: Configure > ID > turn off "Searches passband," then manually set the center frequency to 1500 Hz.

On this weekend's VOA Radiogram, after my voice introduction, I will transmit the MFSK32 RSID. That will be followed by a 30-second tuning signal. If the RxID set Fldigi to the wrong audio frequency, this will give you time to retune to the correct frequency.

After the first MFSK32 RSID, I will transmit no further RSID's until the RSID for the bonus mode of the week: MT63-2000L.

Olivia 16-2000: Last weekend's Olivia 16-2000 did not perform as well as the slower Olivia 32-2000 of the weekend before. In fact, the Olivia 16-2000 may not have been an improvement over MFSK32. This still needs more analysis: I will look through your text files when I respond to your reception reports.

Here is the lineup for VOA Radiogram, program 95, 24-25 January 2015 -- all in MFSK32 except where noted:

1:39 Thirty-second tuning signal at 1500 Hz.
2:07 Program preview
3:10 Early release of State of the Union text*
9:29 Russian reaction to State of the Union comments*
18:22 US-Philippine alliance in the South China Sea*
25:38 Closing announcements*
28:16 MT63-2000L: Bonus mode of the week
