PROJECT KUIPER UNVEILS ANTENNA DESIGN
PAUL/ANCHOR: As any ham will tell you, when it comes to a good signal
it's all about the antenna. That wisdom is also a guiding principle for Project Kuiper, the Amazon satellite constellation designed to provide internet access from space. Here's Kent Peterson, KC0DGY, with that
KENT: Following development and testing this past fall, Amazon has
unveiled its single aperture phased-array design antenna it plans to
use on customer terminals with the company's Project Kuiper satellite constellation. The details were made public on December 16th, revealing
a small, light antenna no more than 12 inches across and with the
capacity of a maximum throughput of as much as 400 Mbps. The small size
has been designed to keep production costs low.
Amazon's planned deployment of the 3,236 low-earth orbit satellite
group got the go-ahead this past summer from the Federal Communications Commission. The project's goal is to provide low-latency broadband
internet access with a focus on serving communities in remote regions
without traditional high-speed internet access.
The project's senior manager of hardware and antenna development, Nima Mahanfar, has said in published reports that the single-aperture
antenna design is unprecendented for the Ka-band, which is in the
microwave range where the transmit and receive frequencies are very far
apart. Project Kuiper boasts a major advancement here, combining
transmit and receive phased-array antennas into one aperture.

SILENT KEY: TORONTO'S ALBERT VANDERBURG VE3ARV
PAUL/ANCHOR: A ham who made many contributions to amateur radio in the
Toronto, Canada, area has become a Silent Key. Dave Parks, WB8ODF,
tells us more about him.
DAVE: Albert Vanderburgh, VE3ARV, who was known in the ham community as
Van, was described as one of the core members of the Toronto FM
Communications Society. Paying tribute in his post on Ham Radio
Canada's Facebook page, Michael Walker, outlined some of Van's further accomplishments. He said Van had also been part of a group that
designed a repeater-linking controller in the 1970s that was so
advanced at the time that the professional engineering association, the
IEEE (Eye Triple E) wrote about it.
In the mid-1960s, Van had been a partner in a startup tech company
called Teklogix. It was there that he helped develop wireless
controlled conveyor systems and handheld devices used to manage
inventory back in the days before electronic barcodes came on the
Van was 96.

SILENT KEY: CW MENTOR ROY CLAYTON G4SSH, SOTA MAINSTAY
PAUL/ANCHOR: The SOTA community is grieving the loss of one of its
mainstays and mentors. Jeremy Boot, G4NJH, tells us about him.
JEREMY: Roy Clayton, G4SSH, has become a Silent Key. According to a
notice on the SOTA Reflector, Roy died on Christmas Day, another
casualty of COVID-19.
In posting the memorial to Roy, John, G4YSS, recalled that Roy had been
a ship's op on Shell Tankers and other marine radio shacks and the UK's
chief Morse Examiner for a good decade. Roy excelled in CW and John
described him as a CW mentor to many, including to himself.
He was also devoted to the mentoring of the next generation. As John
wrote: [quote] "It was Roy's idea. The Scarborough Special Event Group
gave a lot of pleasure and enjoyment over the years as avid collectors
of a series of colourful QSL cards will testify. It also taught several youngsters how to run a GB station and handle a pile-up, some of which
were massive." [endquote]
John wrote that Roy's affections also extended to Citizens Band radio,
where he ran The Chairman Network near Scarborough on Channel 17-FM.
John said: "He would give advice and loan equipment there too, even
sending around a monthly news-letter and was very much looked up to." [endquote]
Roy was 84.

'GET ON THE AIR' CW KEY AUCTION BENEFITS UK CHARITY
PAUL/ANCHOR: The Get on the Air to Care campaign in the UK, which won
this year's Amateur Radio Newsline International Newsmaker Award, has
won another victory for encouraging increased radio contacts during
lockdown. The Radio Society of Great Britain, which partnered with the
UK's National Health Service in this campaign, has raised more than
2,000 pounds - or nearly $2,800 in equivalent US currency, following
its charity auction. An anonymous CW enthusiast made the winning bid of 1,025.99 pounds for a handcrafted Bug CW Key made by Roy Bailey, G0VFS.
The RSGB is matching the funds and donating the sum to the NHS
Charities Together fund. Meanwhile, the related campaign, Get on the
Air for Christmas, continues until January 9th, encouraging holiday
QSOs as a way to ease isolation.

LAWMAKERS SEEK PROBE INTO ARECIBO COLLAPSE
STEPHEN/ANCHOR: In the US, Congress is taking a second look at the
collapse of the Arecibo Observatory in Puerto Rico. Paul Braun, WD9GCO,
tells us more.
PAUL: Lawmakers in Washington, D.C., plan an investigation into the
December collapse at the Arecibo Observatory, just weeks after Puerto
Rico's outgoing governor committed $8 million in resources to rebuild
its historic radiotelescope.
In the December 1st collapse, the dish was gashed beyond repair
following the crash of a 900-ton instrument platform. The telescope, a
valued cornerstone in modern astronomy, was being decommissioned by the
US National Science Foundation following other damage that occurred
weeks earlier. At the time of the final collapse, it had been earmarked
Congress has requested a report by the end of February.

IOWA STUDENTS' BALLOON CIRCLES EARTH A THIRD TIME
STEPHEN/ANCHOR: The world has kept turning into the new year and so too
has one Iowa amateur radio club's balloon project. Jack Parker, W8ISH,
has that story.
JACK: Three circumnavigations after its launch, the Pella Amateur Radio
Club's APRS balloon was still the pride of the Jefferson Intermediate
School fifth graders who'd helped launch it back in November. It ended
the year 2020 as a success in the sky. Transmitting on 144.39 MHz with
the callsign WB0URW-8, the helium-filled balloon had completed three
trips around the world since its November 5th launch and seemed
unstoppable. It was still making its rounds as 2021 dawned, according to
radio club member Jim Emmert, WB0URW. Jim told KNIA-KRLS radio that in
its third trip around Planet Earth, the balloon passed over Canada,
Greenland, Portugal, Spain, Albania and North Macedonia - among many
other places. Powered by solar panels, the balloon can be tracked by
following the link that appears in this week's script on our website at arnewsline.org.
For Amateur Radio Newsline, I'm Jack Parker, W8ISH.
STEPHEN/ANCHOR: According to a January 6th report by the radio station,
the balloon has since completed its fourth trip - a journey that takes
about two weeks. The students have reason to be proud.
PROJECT EYES DIRECT WAY TO GATHER SOLAR POWER
STEPHEN/ANCHOR: Imagine collecting the solar power you need from a spot
much, much closer to the sun. Jim Damron, N8TMW, tells us about a
project that's doing more than just imagining.
JIM: The US Air Force Research Laboratory is hanging its hopes on
something called Helios. It's a key component named after the Greek sun
god and is part of an experiment known as Arachne (Uh-RACK-Knee)
expected to be launched into space in 2024. The formal name of the
project is the Space Solar Power Incremental Demonstrations and Research
solar beaming project.
What's that? The Air Force lab describes it as a project that will
explore a way to harvest solar energy directly from space, where
sunlight is more potent outside the Earth's atmosphere and where solar
panels have more hours of exposure. Through use of something called
"sandwich tiles" and other systems, the experiment will convert the
collected energy to radio waves for beaming back to Earth as usable
Helios, which is being supplied by Northrup Grumman, will house the
platform on which these solar beaming experiments occur. Northrup
Grumman's role has left the Air Force lab free to concentrate on
acquiring a spacecraft where it might all begin to happen.
