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

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."

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, BACKYARDS GO BACK ON THE AIR
PAUL/ANCHOR: What do SOTA activators do when the summits are off limits?
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."
