    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.

    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.

    VOA NEWS

    Matthew Hilburn
    April 16, 2014

    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

    The following is a news story from the VOA Spanish Service…



    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.
