Subj : Amateur Radio Newsline (B) To : All From : Daryl Stout Date : Fri Aug 27 2021 08:30:42 SPAIN PREPARES FOR TWIN SATELLITE LAUNCHES PAUL/ANCHOR: Meanwhile, in Spain, hams await the scheduled launch next month of two AMSAT-EA Genesis satellites. John Williams, VK4JJW, brings us up to date. JOHN: The satellites are called GENESIS-L and GENESIS-N, and their planned launch on September 2nd has been eagerly anticipated by Spain's national amateur radio society, the URE. The launch is to take place at California's Vandenberg Air Force Base, where the two digital repeating satellites will take to the sky along with a number of other satellites. The GENESIS satellites, built by students from the European University, wlil be using Amplitude Shift Keying, and CW. Additional details, and a list of the satellites' working frequencies, can be found on the URL website, which is listed in the script of this week's newscast at arnewsline.org https://www.ure.es/satelites-genesis-de-amsat-ea-2/ For Amateur Radio Newsline, I'm John Williams, VK4JJW. (URE, SOUTHGATE) ** SWEEPING ANTENNA ARRAY DELIVERS GALAXIES IN HIGH-DEFINITION PAUL/ANCHOR: Back here on earth, many of us know the benefits of high- definition, especially when it comes to video images. But now scientists in the UK are making use of some benefits of high-definition imagery, thanks to a huge antenna array in Europe. Jeremy Boot, G4NJH, has those details. JEREMY: Scientists are crediting 70,000 one-metre-high antennas with helping unveil new insights into how our solar system came into being, by providing as-yet unattainable visual details. The array is letting scientists gather ultra-high-definition imagery to get a clearer picture of various galaxies as they give birth to planets and suns. The radio imagery they are using is the result of a linked international network of telescopes known as LOFAR, for Low Frequency Array. Although most of the antennas are in nine nations throughout Europe, the majority are in The Netherlands. According to Neal Jackson of the University of Manchester, the imagery is permitting researchers to see more clearly what happens inside galaxies when planets and suns are being created. He told the BBC, "These high-resolution images allow us to zoom in, to see what's really going on when supermassive black holes launch these jets of material." The project leader, Leah Morabito, of Durham University in the UK, said scientists believe images such as these are giving greater insight into the creation of our own solar system too. According to the BBC, for the array to work, the team had to find a way to gather and digitise signals received by each antenna. The signals were then sent to a central processor for combination with all the other images being gathered by the rest of the array. Leah Morabito told the BBC that the team plans to scan numerous galaxies in the years ahead, adding, "I think we're definitely in for some surprises."

(BBC) ** SPECIAL NYC EVENT MARKS 20TH ANNIVERSARY OF 9/11 PAUL/ANCHOR: Many of the hams who will be on the air on September 11th calling QRZ from New York City, were in a very different place 20 years ago. Some of them hurried to the World Trade Center in Manhattan, as first-responders to the terror strikes that day. They were answering a call then - and this year, they are the ones calling to mark the painful anniversary. The first-responders and their friends and supporters are hams in the Northeast Wireless Radio Club, NW2C, and the Great South Bay Amateur Radio Club, W2GSB. They will be on the air together from 10 a.m. to 8 p.m. Eastern Time, operating special event station W2T, using CW, SSB, and the digital modes. Hams may also contact them via satellite. In the words of their station, Whiskey Two Tango, "We Will Never Forget." Mark it on your calendar.

In New Zealand, the answer is right there in their backyards. We hear more from Graham Kemp, VK4BB. GRAHAM: Nothing - not even a solar flare or even a pandemic - could stop the Backyards on the Air activation from going ahead recently in New Zealand. The pandemic, in fact, was actually the inspiration for the event on Sunday, August 22nd. It was born in the spring of 2020, as lockdown enveloped the nation. A group of SOTA activators looked for new options, because their beloved summits had been declared off limits. Organiser Mark Sullivan, ZL3AB, said this recent activation found participants once again in their backyards, and after two hours of calling QRZ, some boasted contacts with the US and VK, as well as around New Zealand. Mark described his own activation as a bit less successful, owing to a pole that collapsed, and someone's child next-door playing with an incredibly loud toy lawn mower. Mark did encourage and reward experimentation, however. In his invitation to participants, he wrote: "It should go without saying that double points will be awarded to anyone who operates using..... a Delta loop."
