/////////////////////////////////////////// An 'Out of this World' Experience for Palmetto Scholars: Posted: 10 Feb 2017 04:05 PM PST http://www.eham.net/articles/38635 A group of Lowcountry students have an assignment that's "out of this world" Friday. Students in Palmetto Scholars Academy's Ham Radio Club will talk directly to astronauts on the International Space Station. "This is an authentic math and science experience that's unparalleled," said Kellye Voigt, a teacher at Palmetto Scholars Academy. "How often do you get to speak to an astronaut flying over your school?" The school was just one of eight schools chosen for the project across the country. The entire student body was asked to generate questions to ask the astronauts. Twenty of the questions were selected and will be asked live to the commander of the International Space Station, Shane Kimbrough. "You never hear about this type of thing happening, and next thing you know, I'm a part of it," said Max Freedman, President of the school's ham radio club. "It excites me about space and amateur radio in itself." /////////////////////////////////////////// Radio Cub Has Global Reach: Posted: 10 Feb 2017 04:04 PM PST http://www.eham.net/articles/38634 The owners of the cars are amateur radio enthusiasts, or "hams", of the Pierre Amateur Radio Club. The club was reincorporated in 1968, with about 12 active members currently, said Jim Zaradnicek, one of the members. They meet on the second Thursday of the month. Zaradnicek has been an active member the longest. He's made roughly 120,000 radio contacts with people around the world since 1995. Typically, the hams turn on their radios randomly and make contact with other hams who are also broadcasting their signals at the same time, Zaradnicek said. Zaradnicek said the topics of discussion vary. "There's no limit to the things you're talking about. It's just like visiting a friend over the telephone except everyone you meet is a new friend," he said. /////////////////////////////////////////// Preparing for a Sun Shock: Posted: 10 Feb 2017 04:04 PM PST http://www.eham.net/articles/38633 Solar scientists say it's not a matter of if the Earth will one day be in the path of an intense blast of energy from the sun, it's when. The results are hard to think about, power out for days, weeks, maybe even months or years. Banks, grocery stores, gas stations, all closed. Is there anything that can be done to prepare for a sun shock? In Thursday night's special report, which you can find by clicking here, Newschannel 3 showed how a single shot of solar energy aimed at our planet could have catastrophic results. It's happened before, nearly 160 years ago our planet was directly in the cross hairs of an X-class flare. Then, the results weren't so bad, we didn't have electricity or depend on satellites. Today it's a very different story. Imagine, in an instant the sun releases a blast of energy equivalent to millions of nuclear bombs, shooting energized particles toward the Earth at three million miles per hour. That flare arrives in 30 hours, destroying all of our satellites along the way, blowing out electrical transformers. The power grid goes down, and it may stay down for a very long time. It's happened before. In 1989 a solar flare knocked out power to millions of people in Canada for hours. The flare could have been much stronger. /////////////////////////////////////////// VK6WIA -- NewsWest, 12 February 2017: Posted: 10 Feb 2017 03:59 PM PST http://www.eham.net/articles/38632 In the news this week we have a special event station in VK8, Foundation Courses at Ham College, the Hills Amateur Radio Group annual HARGfest, an update from Ex-WIA Director Andrew VK6AS, a Morsecodians Exhibition at Wireless Hill and a look at what sun-spots mean to Amateur Radio. /////////////////////////////////////////// Foundations of Amateur Radio -- #88: Posted: 10 Feb 2017 03:58 PM PST http://www.eham.net/articles/38631 The pimples on the Sun that erupt and make a mess are called Sun-spots and they make it possible for you to use your Amateur Radio on HF for long distance communication via the ionosphere. How does this actually work and what is a Sun-spot actually and why are Sun- spot numbers not the same as the numbers of dots on the Sun. This week I investigate how getting Sun burned is like heating the ionosphere. /////////////////////////////////////////// School Club Roundup Starts Monday: Posted: 10 Feb 2017 10:10 AM PST http://www.eham.net/articles/38630 Objective: To exchange QSO information with club stations that are part of an elementary, middle, high school or college. Non-school clubs and individuals are encouraged to participate. |
