24 Jan 2012, Owen McNally: “Still very much an irrepressible life-force at 70, Chucho Valdés, the renowned Cuban pianist, composer and bandleader, is on a winter tour of the United States that sets down for high-energy maneuvers … at the cabaret series at the University of Connecticut’s Jorgensen Center for the Performing Arts. … The title track [of his new CD], ‘Chucho’s Steps,’ … is a 50-bar adventure in challenging harmony in which he pays tribute to John Coltrane’s intimidating masterpiece, ‘Giant Steps.’ Valdés notes that as a young man in Cuba he would listen on short-wave radio to a program called ‘The Jazz Hour’ on The Voice of America, an experience that opened his ears to Coltrane’s innovations and the creative fervor of the new, iconoclastic music that was fermenting in the States.”

“The news may be good. The news may be bad. We shall tell you the truth.” – William Harlan Hale; February 1, 1942
Such began the first broadcast of a small team of dedicated men transmitting live from a claustrophobic New York City studio into Nazi Germany. Their group had no name, although their first broadcast was titled Stimmen aus Amerika—Voices from America. The equipment they used was borrowed. They had no direction as to what they would broadcast, except the truth. At that moment, the United States stepped into a role as guardian of the power of ideas and honest messenger of information to all corners of the world.
From the very beginning, the Voice of America has held at its core the mission to present to the world the policies and culture of the United States, while reporting on global news events accurately, clearly, and objectively. It has been one of the U.S.’s most effective public relations initiatives. All around the world, the Voice of America is highly respected as an honest and fair messenger, and in many places, as the only comprehensive source of news free from propaganda. From Nazi Germany to Communist Eastern Europe to Kim Jong Il’s North Korea, VOA has often been the only connection to the outside world that people of repressive regimes have. […]
Today, VOA broadcasts through the Internet, television, and a network of AM, FM, and shortwave radio signals. The approximately 1500 hours of programs per week include features on American culture, learning English, international news, discussion programs, and regionally focused programs to address the needs of the local populations. VOA broadcasts in 43 languages, televising programs in 26 of those, and reaches 141 million people weekly. All this makes VOA one of the largest multimedia news organizations in the world.

For those of you readers who often feel you’re alone in your enthusiasm for radio, I highly encourage you to attend the NASWA-sponsored SWL Fest in Plymouth Meeting, Pennsylvania this year. The ‘Fest is jam-packed with radio-related information and attended by many radio kindred spirits. From their website :
The Winter SWL Fest is a conference of radio hobbyists of all stripes, from DC to daylight. Every year scores of hobbyists descend on the Philadelphia, Pennsylvania suburbs for a weekend of camaraderie. The Fest is sponsored by NASWA, the North American Shortwave Association, but it covers much more than just shortwave; mediumwave (AM), scanning, satellite TV, and pirate broadcasting are among the other topics that the Fest covers. Whether you’ve been to every Fest (all 25, starting with the first year at the fabled Pink & Purple Room of the Fiesta Motor Inn) or this year’s will be your first, you’re sure to find a welcome from your fellow hobbyists.
For 2012, its 25th Anniversary, the Winter SWL Fest will have three days of sessions where you can learn about the latest developments in the radio listening hobbies, but there’s so much more going on. There’s a silent auction that takes place, where you’re bound to find something of interest. There’s the Hospitality Suite, where attendees partake of tuning oil and other treats and engage in spirited conversations. There is the closing Banquet, with after-dinner remarks by a luminary from the field, often one of the many broadcasters who attend the Fest, followed by the raffle, where you could win one or more of the dozens of prizes, ranging from pens from stations up to top-notch communications receivers. And of course, the infamous midnight ride of Pancho Villa that closes things out every year.
Your hosts, Richard Cuff and John Figliozzi, work throughout the year to ensure that attendees have a great time over the weekend, and by all accounts, they succeed stunningly. How else could this event have lasted for 25 years (!) and draw people from around the world to southeastern Pennsylvania? Won’t you join us?
If you’re interested in attending the SWL Fest, too, go to the official website and register!
On January 11, 2012 the National Security Agency (NSA) released a pre-1995 article entitled “Receiver Dynamics” from its classified internal magazine, Cryptologic Quarterly. It contains an excellent, well-written explanation of the specifications of shortwave receivers used by some of NSA’s K4 divisions.
Thanks to Ed in the SWLfest list for the tip!
I think this is one of the best, simple explanations of space weather that I’ve seen lately:
Space weather, as it is called, originates with solar magnetic activity. The sun is a giant spinning ball of charged particles. In addition to its spin, the heat released from the core through nuclear fusion eventually sets the upper layers of the sun into a kind of boiling motion called convection. All that motion — spin and convection — means lots of charged particles streaming this way and that. Since current (the flow of charges) produces magnetic fields, the outer domains of the sun are ruled by magnetism. Magnetic fields are the source of all those cool images of giant flares erupting in planet-spanning arcades of super-hot plasma. It’s also the source of so-called Coronal Mass Ejections or CMEs, which are, essentially, the space storms that space weather is all about.
CMEs are eruptions of matter and magnetism from the sun into space. A typical CME will blow 10 billion kilograms (about 22 billion pounds) of solar plasma into space along with enough energy to represent a flotilla of 220 aircraft carriers moving at 500 km/s. The fact the CME’s are quite common says a lot about the power locked up in an ordinary star like the sun.
While 1 to 3 CMEs may occur every day, we only the notice the ones that slam into the Earth on their journey across the solar system. When a CME crosses the Earth it runs into our planet’s own magnetic field. Charged particles from the CME get trapped by the Earth’s magnetic field and stream down toward the planet’s surface near the poles.
When those CME particles, running down magnetic field lines, strike atmospheric gas atoms, the collisions cause the atoms to light up like Christmas tree bulbs. That is the origin of the simmering walls of color we called aurora. There was a time when pretty lights were all there was to space weather. Those days are over.
