Thanks to all. /////////////////////////////////////////// Just Ahead In Radiosport: Posted: 24 Dec 2015 06:49 AM PST http://www.eham.net/articles/35854 Just Ahead In Radiosport: /////////////////////////////////////////// North Korea On the Air for First Time in More than a Decade: Posted: 24 Dec 2015 06:49 AM PST http://www.eham.net/articles/35853 In an unexpected turn of events, Polish DXer Dom Grzyb, 3Z9DX, who visited North Korea -- officially the Democratic People's Republic of Korea (DPRK) -- this month in advance of a planned Amateur Radio operation early next year, showed up on the air from the most-wanted DXCC entity around 0000 on December 20. During a "demonstration" for North Korean officials, P5/3Z9DX made nearly 800 DXers -- most of them in Asia -- very happy over the couple of days he was on the air. Grzyb operated mostly on 15 meters with some excursions on 20 and 10 meters, SSB only. The P5/3Z9DX preview was the first from North Korea since the 2001-2002 operation by Ed Giorgadze, 4L4FN. /////////////////////////////////////////// FCC Proposes to Penalize CA Ham $25000 for Causing Intentional Interference Posted: 24 Dec 2015 06:48 AM PST http://www.eham.net/articles/35852 The FCC Enforcement Bureau has proposed fining William F. Crowell, W6WBJ (ex-N6AYJ), of Diamond Springs, California, $25,000 for intentionally interfering with other Amateur Radio operators and transmitting prohibited communications, including music. /////////////////////////////////////////// Philippine Radio Amateurs Respond To Typhoon Threat: Posted: 24 Dec 2015 06:46 AM PST http://www.eham.net/articles/35851 The Philippine Amateur Radio Association (PARA) activated its Ham Emergency Radio Operations (HERO) on December 12 as Typhoon Melor -- locally called Typhoon Nona -- threatened the Philippine archipelago. The storm boasted winds up to and slightly in excess of 100 MPH. National Traffic System Chairman Jojo Vicencio, DU1VHY, announced the activation during the early-morning DU NET. HERO used 7.095 MHz for emergency traffic, and other hams in the region cooperated in keeping the frequency clear. /////////////////////////////////////////// Preliminary CQ World Wide Survey Results Suggest Contesters Trending Older: Posted: 24 Dec 2015 06:47 AM PST http://www.eham.net/articles/35850 The CQ World Wide Contest Committee has posted the preliminary results of its September survey of CQ WW participants. The committee received 5117 responses from contesters around the world, the greatest number -- nearly 2600 -- from Europe. An analysis of the results showed that most survey participants were in the older age brackets and that there were not many youth participants. /////////////////////////////////////////// US Applicants Move Into Next Stage of ARISS Contact Selection Process: Posted: 24 Dec 2015 06:46 AM PST http://www.eham.net/articles/35849 Amateur Radio on the International Space Station (ARISS) has announced that the proposals of 17 schools and organizations submitted during the recent application window will move forward into the next stage of planning to host Amateur Radio contacts with ISS crew members. Once scheduled, the contacts will take place between July and December 2016. /////////////////////////////////////////// AO-85 Slow Scan TV Image Likely a Prank, Not a Test: Posted: 24 Dec 2015 06:46 AM PST http://www.eham.net/articles/35848 A Slow Scan TV (SSTV) image that a Brazilian radio amateur reported receiving on December 13 from Fox-1A (AO-85) was most likely a prank, not any sort of official test of the satellite's SSTV capabilities. AMSAT Vice President for Engineering Jerry Buxton, N0JY, said the Robot 36 image, which depicted a cartoon fox and the legend "Testing Fox-1A/AO-85 AMSAT satellite," was of terrestrial origin and transmitted via the AO-85 satellite's transponder. /////////////////////////////////////////// Straight Key Night is a New Year's Day Tradition: Posted: 24 Dec 2015 06:45 AM PST http://www.eham.net/articles/35847 Every day is a good day to operate on CW, but set some time aside on New Year's Eve and Day to enjoy Straight Key Night SKN). The annual event gets under way a 000 UTC on January 1 (New Year's Eve in US time zones). The 24-hour event is not a contest but a day dedicated to celebrating our CW heritage. Participants are encouraged to get on the air and simply make enjoyable, conversational CW contacts, preferably using a straight (hand) key or a semi-automatic key (bug). Activity traditionally centers on CW segments in the HF bands. There are no points or obligatory exchange. The only requirement is just to have fun! /////////////////////////////////////////// RTTY Roundup is a Good Way to Kick Off the 2016 Contest Calendar: Posted: 24 Dec 2015 06:44 AM PST http://www.eham.net/articles/35846 The ARRL RTTY Roundup over the January 2-3 weekend is a veritable digital festival, so dust off those keyboards! In addition to conventional Baudot, RTTY Roundup ops may use ASCII, AMTOR, PSK31, and Packet (attended). It's very easy to get on RTTY and other digital modes, and some late-model transceivers even have RTTY and other digital capabilities built right into the radio. Participation in this annual operating event has grown along with the enthusiasm for digital modes, and newcomers are always welcome to join the fray. /////////////////////////////////////////// Kids Day is Sunday, January 3: Posted: 24 Dec 2015 06:45 AM PST http://www.eham.net/articles/35845 The next Kids Day will be Sunday, January 3, 2016, from 1800 to 2400 UTC. The twice-yearly event, sponsored by the ARRL and The Boring (Oregon) Amateur Radio Club, is an excellent opportunity to showcase Amateur Radio and Amateur Radio satellites to youngsters and even to hand over the keys so they can get some hands-on experience. Share the excitement with your own children or grandkids or youngsters in the neighborhood! /////////////////////////////////////////// International DX Association Announces Humanitarian Fund: Posted: 24 Dec 2015 06:44 AM PST http://www.eham.net/articles/35844 The International DX Association (INDEXA) has announced the formation of a fund -- "Hams with Hearts" -- to support humanitarian projects carried out by DXpedition teams. Thanks to an initial contribution by Zorro Miyazawa, JH1AJT, INDEXA will be able to begin humanitarian support grants beginning in mid-January 2016, the announcement said. /////////////////////////////////////////// Radio Broadcasting Remote Pickup Pioneer George Marti, W5GLJ, (SK): Posted: 24 Dec 2015 06:43 AM PST http://www.eham.net/articles/35843 George Marti, W5GLJ, who pioneered and manufactured remote pick-up (RPU) technology to allow radio stations to originate broadcasts away from the studio wirelessly -- and lobbied the FCC to authorize its use -- died on December 13 at age 95. Marti lived in Cleburne, Texas, where he had served as mayor for 12 years. /////////////////////////////////////////// In Brief... Posted: 24 Dec 2015 06:43 AM PST http://www.eham.net/articles/35842 ARISS Postpones Anniversary SSTV Event: The Amateur Radio on the International Space Station (ARISS) Slow-Scan TV event set for December 26-27 has been postponed due to "complications in planning," ARISS has announced. ARISS now is targeting mid-January as the next possible opportunity. /////////////////////////////////////////// Technician License Course In Oklahoma City: Posted: 24 Dec 2015 06:40 AM PST http://www.eham.net/articles/35841 The Oklahoma City Autopatch Association will conduct a Technician License Course beginning on Thursday, 7 January 2016 running eight weeks to Thursday 25 February 2016, 6-9 PM. /////////////////////////////////////////// Ministry-Eagle River Memorial Donate Space to Amateur Radio: Posted: 23 Dec 2015 05:01 PM PST http://www.eham.net/articles/35840 Recently the Vilas County Amateur Radio Club activated their first radio repeater using tower space provided by Ministry Eagle River Memorial Hospital. Hospital spokesperson Mark Dascalos says the hospital was glad to help the ham operators... "....here in the Northwoods we have difficulty with cell signals and probably equal-wise with radio signals and it was an opportunity to use our tall antenna at the hospital to install a repeater that would enhance(the club's) abilities in a ham radio aspect to be able to communicate with other members...." Dascalos says during times of natural disasters, ham radio often is still operating when other signals are inoperable. Dascalos says club members intend to use the expanded signal to provide communication support for bike tours, races and other community events along with emergency communications. Hams are licensed by the FCC and are well-known for helping government and non-government entities in a time of need. /////////////////////////////////////////// Leeds Nostalgia: Broadcasts from the City: Posted: 23 Dec 2015 05:00 PM PST http://www.eham.net/articles/35839 In 1955 these members of the Leeds Amateur Radio Society were broadcasting using low powered equipment and it wasn't long before the city's skyline was altered with the advent of the Tinshill Radio Station. /////////////////////////////////////////// Description of Mechanism that Halts Solar Eruptions: Posted: 23 Dec 2015 05:00 PM PST http://www.eham.net/articles/35838 Among the most feared events in space physics are solar eruptions, massive explosions that hurl millions of tons of plasma gas and radiation into space. These outbursts can be deadly: if the first moon-landing mission had encountered one, the intense radiation could have been fatal to the astronauts. And when eruptions reach the magnetic field that surrounds the Earth, the contact can create geomagnetic storms that disrupt cell phone service, damage satellites and knock out power grids. NASA is eager to know when an eruption is coming and when what looks like the start of an outburst is just a false alarm. Knowing the difference could affect the timing of future space missions such as journeys to Mars, and show when steps to protect satellites, power systems and other equipment need to be taken. At the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL), researchers led by physicist Clayton Myers have identified a mechanism that may halt eruptions before they leave the sun. The finding, reported in the December 24-31 issue of Nature magazine, provides a potentially important way to distinguish the start of explosions from buildups that will fail. This work was supported by the DOE office of Science. The violent eruptions, called "coronal mass ejections," stem from a sudden release of magnetic energy that is stored in the sun's corona, the outermost layer of the star. This energy is often found in what are called "magnetic flux ropes," massive arched structures that can twist and turn like earthly twine. When these long-lived structures twist and destabilize, they can either erupt out into the solar system or fail and collapse back toward the sun. The researchers found in laboratory experiments that such failures occur when the guide magnetic field -- a force that runs along the flux rope -- is strong enough to keep the rope from twisting and destabilizing. Under these conditions, the guide field interacts with electric currents in the flux rope to produce a dynamic force that halts the eruptions. PPPL has discovered the importance of this force, called the "toroidal field tension force," which is missing from existing models of solar eruptions. |
