Sat 1600-1630 17860 kHz
Sun 0230-0300 5745 kHz
Sun 1930-2000 15670 kHz
All via the Edward R. Murrow transmitting station in North Carolina.
Looking ahead: VOA Radiogram on 31 May and 1 June 2014 will be the “VOA Radiogram Picture Show.” We will experiment with the X1, X2, and X4 transmission speeds of MFSK images, using MFSK32, 64, and 128. And we will transmit an EasyPal image. Download the EasyPal software from vk4aes.com . For practice, radio amateurs transmit EasyPal images (mostly with Internet assistance) on 14233 kHz.
The Mighty KBC will transmit a minute of MFSK64 each Saturday at 1130 UTC on 6095 kHz and Sunday at 0130 UTC (Saturday 9:30 pm EDT) on 9925 kHz. The transmitters are in Germany.
The QSL for VOA Radiogram, program 57, 3-4 May 2014, showing MFSK32 images as received and decoded in various parts of the world.
Robert in Texas conducted this interesting experiment during VOA Radiogram, 4 May 2014, 1930-2000 UTC, 15670 kHz:
I received the Sun 1930-2000 15670 kHz broadcast 4 times simultaneously with the exact same radio, antenna, and settings with the exception of mode. I had 4 receive slices set up in the radio on the 15.670 MHz on AM, Synchronous AM, LSB, and USB. See the picture for the results.
The text was generally received 100% with a few errors in the LSB and USB. Also on LSB and USB I had to set offsets off of 1500 (1472 for LSB and 1531 for USB) before the text would decode properly.
Videos of VOA Radiogram, program, 57, during the weekend of 3-4 May 2014, including this remarkable example embedded in the document by listener T.W. in Japan, for reception Saturday at 0930 UTC on 5745 kHz, via North Carolina, far from Japan…

Two videos of VOA Radiogram, program 56, 26-27 April 2014, have been provided by Tim in Colorado.
The first is from Saturday at 1600-1630 UTC on 17860 kHz, when reception and decoding were very good…
And from Sunday at 0230-0300 UTC on 5745 kHz. Reception was not as good, but the text decoded 100%…
T.W. in Japan provided this video of an amazing decode of the broadcast Sunday at 1930-2000 UTC on 15670 kHz. Amazing when considering the distance from North Carolina…

For the weekend of 26-27 April, we will transmit only one mode at a time.
One of the VOA News stories, about the Ukraine-Russia cyberwar, is very interesting, but it is also long and would take more than 10 minutes in MFSK32. So it will be in the faster MFSK64L mode.
Everything else will be MFSK32 except for the surprise mode during the closing music.
Here is the lineup for VOA Radiogram, program 56, 26-27 April 2014:
1:33 MFSK32: Program preview
2:45 MFSK64L*: Ukraine Russia cyberwar
9:30 MFSK32: Heat into electricity, with image
13:46 MFSK32: Electric cars at the NY auto show, with image

Developers Expect to Become Wealthy
VOA News
April 16, 2014
Results of a survey of 1,000 U.S. software developers, released
this week, show that a majority of them think they will become
millionaires and that their jobs are invulnerable to economic
downturns.
A study commissioned by Internet technology company Chef also
shows that developers see their profession as having increasing
power and influence, both in business and society. About 71
percent of the surveyed said they have been involved in political
and civic activities for 50 hours per year on the average.
At one point it was thought to be a profession vulnerable to an
influx of temporary foreign workers, and many developers were
threatened by the possible export of their jobs to other
countries. Now 66 percent of developers expect near-term salary
rises, while as many as 56 percent of them expect to become
millionaires.
According to the study, 94 percent think they’ll have
revolutionary influence in important parts of the economy, and 95
percent think they are among most valued employees in their
company.
Once viewed as introverts with poor social skills, developers now
see themselves as empowered to influence changes to both products
and services.

A planet’s wobble may greatly enhance its ability to host life,
even if the planet is far away from its star, new research says.
Wobbling, or axial shifting, means that a planet changes its tilt
much in the same way as a top that’s about to stop spinning.
Extreme wobbling may be explained by competing gravitational
pulls between the planets’ star and another nearby planet.
These wobblers could change their orientation within “tens to
hundreds of thousands of years – a blink of an eye in geologic
terms,” scientists said in a new paper.
A wobbling planet that might otherwise be a frozen world could
have liquid water — thought to be necessary to support life —
because the poles would face the planet’s star, allowing the ice
to melt, researchers said.
"Planets like these are far enough from their stars that it would
be easy to write them off as frozen, and poor targets for
exploration, but in fact, they might be well-suited to supporting
life,” said Shawn Domagal-Goldman, an astrobiologist at NASA’s
Goddard Space Flight Center in Greenbelt, Maryland, in a
statement. “This could expand our idea of what a habitable planet
looks like and where habitable planets might be found.”
Researchers say they may have already spotted planets with “crazy
tilt-a-world” wobbling.
Around the star Upsilon Andromedae, two enormous planets were
found to be inclined at an angle 30 degrees to each other. In our
solar system, the orbits of the 8 planets only vary by 7 degrees,
scientists said.
In addition to the observations of Upsilon Andromedae, scientists
ran “thousands of simulations for planets in 17 varieties of
simplified planetary systems.” The modeling considered planets
with the same mass as Earth that orbited a sun-like star and have
gas giants nearby.
In the models, researchers adjusted the tilts of the orbits, the
leans in the axes of rotations and the ability of light to
penetrate the planet’s atmosphere.
Some planets are constantly on the move, while others are
relatively stable. Our planet is not much of a wobbler.
"Earth has a fairly stable tilt, but it is close enough to the
Sun to avoid prolonged snowball events,”e¾ex John Armstrong of
Weber State University and the lead author of the research paper,
at Weber State University. “However, if it was a bit further away
it would need a thicker atmosphere (more greenhouse) or a wobbly
axis - the later is the new bit we are proposing.”
The paper appeared in the April 2014 issue of Astrobiology.

Cambodia Technology Adviser Criticizes Cybercrime Draft Law
Theara Khoun
April 15, 2014
PHNOM PENH - A senior Cambodian government adviser on information
technology says a draft cybercrime law is unnecessary and could
lead to demonstrations and unrest if passed as currently written.
Phu Leewood says the current criminal code can be used to
prosecute offenders, so a separate law is not needed.
He adds that the Ministry of Post and Telecommunications, which
drafted the law, should have had a public comment period and
consulted with civic organizations.
"If there is no such process, it means Cambodian voices are
ignored,” he said. “If such a law is passed, there will be
strong reaction from the public, as it hasn’t been involved.”
He adds the law was written by people who lack technical
knowledge, and without consultations with legal experts, judges
or prosecutors.
Government officials have not been available for comment on the
draft law, which was publicized online last week by the Cambodian
Center for Human Rights. Chak Sopheap, the center’s executive
director, says the law, if passed in its current form, will be
dangerous to free speech.
Critics say the draft law, made public last week, has vague
language that could be abused by authorities and lead to curbs of
online freedoms.
This report was produced in collaboration with the VOA Khmer
service.

Google Buys Drone Company
George Putic, KI4FNF
April 15, 2014
In its latest purchase of high-tech companies, Google has
acquired a manufacturer of solar-powered drones that can stay in
the air almost indefinitely, relaying broadband Internet
connection to remote areas. It is seen as yet another step in the
U.S.-based Web giant’s bid to bring Internet to the whole world.
Even as it experiments with self-driving cars on the ground,
Google has been acquiring companies that manufacture pilotless
flying vehicles - aircraft that can stay aloft for very long
periods of time, such as solar-powered balloons and drones.
The Internet giant aims to bring Web access to remote areas of
the world, which it says could help speed disaster relief or
monitor environmental damage. And it says atmospheric satellites
could also provide high-resolution aerial images for its Google
Earth service.
Its newest acquisition, the 20-employee, New Mexico-based company
Titan Aerospace, plans to manufacture a larger version of its
successful solar-powered drone Solara.
Chief Technical Officer, Maximus Yaney, says it will be as
efficient as a satellite, but much less expensive to operate -
just one-hundredth of the cost.
"What we’re focusing on from a capability perspective is being
able to provide these kinds of services as an alternate or adding
to satellite platform capabilities,” he said.
He says the new drone, Solara 50, will be able to fly almost 20
kilometers above the earth, providing the Internet signal in a
radius of almost 420 kilometers… and stay aloft for almost five
years.
"Solar-powered, you have the capability of staying up there
effectively indefinitely, you’re simply limited by the
rechargeable batteries,” he said.
Other technology companies are also interested in the potential
of drones. Earlier this year, Internet-based giant Facebook
acquired the British drone manufacturer Ascenta, while the
Internet retail company Amazon is experimenting with drones for
package deliveries

ONU: Vuelve el fenómeno de El Niño
Voz de América - Redacción
15.04.2014
El organismo meteorológico de la ONU informó que la mayoría de
los modelos climáticos pronostican, desde ya, que a mediados de
año se podría desarrollar el fenómeno climático de El Niño.
Sin embargo, aún se desconoce cuál sería su fuerza.
El reporte de La Organización Meteorológica Mundial señala que
"los pronósticos de los modelos indican un potencial bastante
grande para El Niño, más probablemente para fines del segundo
trimestre de 2014”.
El informe de la ONU revela que para el período de junio a
agosto, se alcanzarán los umbrales de El Niño, de acuerdo con la
mayoría de modelos climáticos.
El Niño, caracterizado por temperaturas inusualmente cálidas en
la superficie del centro y el este del Océano Pacífico tropical,
tiene un impacto significativo en el clima en muchas partes del
mundo y una influencia de calentamiento sobre las temperaturas
globales, dice la ONU.
Estas predicciones de La Organización Meteorológica Mundial
coinciden con pronósticos de varios organismos meteorológicos
nacionales, de Estados Unidos Japón y Australia.
