/////////////////////////////////////////// WIA Submission to ACMA on High Power Trial: Posted: 17 May 2013 05:04 PM PDT http://www.eham.net/articles/30198 The WIA has lodged a submission to the ACMA concerning the High Power Trial. The WIA submission is based on responses received from trial participants following a call for information, and also on its own observations. The WIA's submission (below) notes that the trial appears to have gone very well, with licensees generally having a sound understanding of the self-assessment process and the use of EMR assessment tools. The WIA also notes that it is not aware of any incidences of interference to other spectrum users, or an increase in interference to other Radio Amateurs, or an increase in the noise floor on affected amateur bands. Many responders noted that the advantage of the higher power was most evident in contesting, when many stations are calling on the same frequency and all at once, and the relatively small 3-4 decibel increase in radiated power (from 400W pX to 1kW pX) can make all the difference in being heard. /////////////////////////////////////////// Peter Brown, VK4PJ (SK): Posted: 17 May 2013 05:03 PM PDT http://www.eham.net/articles/30197 Peter Brown became a silent key on the 8th of May 2013 - He had only recently chalked up the century - he was 100 years old. Peter was a WIA stalwart, being the national contest manager during the 70~80s. He was behind the introduction of the WIA Contest Trophy, one that was before its time - these days with results of contests able to be produced much more quickly the trophy has been reintroduced in 2012/13 a fitting tribute to his love of the hobby. The trophy bears his name and callsign and will be awarded at the WIA AGM in Perth this year after an absence of some 25 years. It is believed by his friends that Peter was first licensed in the early 1950's. There is evidence that he was issued with Amateur Radio licence QA.244 on 12 May 1963 so we can say with some certainty that he has been licensed for well over 50 years. /////////////////////////////////////////// Region Tunes in to Hamvention: Posted: 17 May 2013 05:02 PM PDT http://www.eham.net/articles/30196 DAYTON, Ohio (WDTN) - Nearly 25,000 amateur radio operators from around the world are expected at the 62nd Annual Dayton Hamvention May 17-19 at the Hara Complex. /////////////////////////////////////////// Smartphone Satellites Snap Some Amazing Photos: Posted: 17 May 2013 05:01 PM PDT http://www.eham.net/articles/30195 Three consumer smartphones that were sent into orbit around Earth last month snapped some incredible photos of our planet from space. The images were snitched together as part of NASA's PhoneSat initiative, which aims to show how existing technology could be incorporated into powerful low-cost satellites. Named Alexander, Graham and Bell, the trio of tiny cube-shaped PhoneSats was launched into orbit during the inaugural test flight of Orbital Sciences Corp.'s Antares rocket on April 21. Each PhoneSat had a smartphone for a brain. Alexander and Graham : both PhoneSat 1.0s : were battery-powered and carried a Nexus One smartphone running Goggle's Android operating system. Bell was a more advanced PhoneSat 2.0, built around a Nexus S smartphone running on Android. The nanosatellite was also outfitted with solar panels and a two-way radio that allowed engineers to control the satellite from the ground. What's perhaps most remarkable is that they were cheap. The three PhoneSats cost just $3,500 to $7,000 each; most satellites can cost upwards of $1 million. As part of this demonstration, the smarthphones' cameras captured photos of Earth and converted them into image-data "packets" to be beamed back on the amateur radio spectrum. These packets were then decoded and put together by the PhoneSat team and amateur ham radio operators. /////////////////////////////////////////// Fallout from Huge Solar Flare to Sideswipe Earth: Posted: 17 May 2013 05:01 PM PDT http://www.eham.net/articles/30194 A huge explosion on the sun will deal Earth a glancing blow Friday but should not pose a threat to the planet, scientists say. The sun storm erupted late Tuesday during a powerful solar flare -- the fourth unleashed by a single sunspot in just 48 hours -- and hurled a massive cloud of charged particles out into space at millions of miles an hour. Such eruptions -- known as coronal mass ejections, or CMEs -- can wreak havoc if they hit Earth squarely, temporarily disrupting GPS navigation, satellite communications and power grids. But this one isn't aimed directly at us, so there's no cause for alarm, experts say. |
