/////////////////////////////////////////// Propagation Forecast Bulletin #53 de K7RA: Posted: 30 Dec 2016 06:25 AM PST http://www.eham.net/articles/38337 The Australian Space Forecast Centre issued a Geomagnetic Disturbance Warning on December 29 at 0010 UTC. "A recurrent equatorial coronal hole will soon reach geoeffective location on the solar disk. The size of the current coronal hole is relatively larger compared to its characteristics during the previous rotation. The co-rotating interaction region and subsequent high speed streams associated with the coronal hole is expected to affect Earth from late 30 December. Auroras may be visible on the local nights of 30 and 31 December in Tasmania and possibly from the coastline of Victoria." /////////////////////////////////////////// New Amateur Radio FM Transponder CubeSat Now in Space: Posted: 30 Dec 2016 06:24 AM PST http://www.eham.net/articles/38336 The BY70-1 CubeSat launched on December 28 from the Taiyuan Space Launch Center in China, but in a lower orbit than intended.

Hams respond to the typhoon the Philippines. Radio Australia begins its shortwave shutdown -- and we talk to possibly the oldest continuously operating phone net. All this and more as Amateur Radio Newsline Report 2044 comes your way right now. /////////////////////////////////////////// Devices Could Make Motorist Hang Up and Drive: Posted: 29 Dec 2016 04:17 PM PST http://www.eham.net/articles/38332 Wouldn't it be great if you could switch off the cellphone signal to the guy who's gabbing on his phone while driving distractedly in front of you? A group of U.S. amateur radio fans were close to developing that "hang up" device in the 1990s, inspired by military technology during the first Gulf War. When George H. W. Bush ordered an offensive on Iraq that lasted 100 hours in February 1991, all of America watched as 42 Scud missiles were fired into Israel over a period of several weeks. The only effective defenses to these fatal attacks were electronics that sensed incoming Scuds and launched Patriot warhead-seeking missiles, and it wasn't very successful. But the efforts that technicians from arms maker Raytheon expended to help our military industry protect Israel were legendary. About this same time we were noticing folks driving at congestion-inducing 50 mph speeds on I-696 and on other jam-sensitive roads in the normally safe, free-flowing left lanes. Almost always, this happened in cars driven by people engaged with their new cellphones. The drivers were rarely ticketed. Frustrated by this, a group of amateur radio experts around the U.S. wondered if the same efforts used to intercept Scud missiles could help reduce cell phone-related distracted driving. /////////////////////////////////////////// Foundations of Amateur Radio -- #82: Posted: 29 Dec 2016 11:29 AM PST http://www.eham.net/articles/38331 So, do we really understand our hobby to the point where we can make that explanation? I think not, more to the point, neither do you. The Internet and the airwaves are full of explanations of how things in Amateur Radio work and many of them disagree with each other, sometimes loudly. |
