HYTERA COMMUNICATIONS BANNED FROM WORLDWIDE SALE OF 2-WAY RADIOS
PAUL/ANCHOR: Our top story this week brings the latest chapter in a long-simmering patent dispute between Motorola and Hytera. A US federal
court in the Northern District of Illinois has prohibited Hytera Communications, a major provider of two-way radios, from selling,
distributing or importing its radios [quote] "until further notice,"
[endquote] requiring the company to pay a daily fine of $1-million to
the court if they do not comply.
Even as it acted in compliance with the US court injunction, Hytera
separately announced it was withdrawing its own counterclaims against Illinois-based Motorola that it had filed in a Shenzhen court. Hytera
has denied claims that its H-series radios have infringed on Motorola's trademark and copyright.
The US court injunction banning the radios' global sales came just as
Hytera was preparing to show at ISC West, a major security conference
being held in Las Vegas, Nevada, starting on April 9th.

HAMS SUMMON HELP AFTER DEATH VALLEY DISTRESS CALL
PAUL/ANCHOR: When getting on the air from a national park isn't a POTA activation - but a call for help - other hams are always there, as one
new operator in California discovered. We hear this story from Ralph
Squillace KK6ITB.
RALPH: A distress call from an amateur radio operator stranded in Death
Valley mobilized some quick-acting amateur radio operators - some of
them hundreds of miles away - to get the ham and his family some
assistance. According to personal accounts and media reports, Moritz
Wacker, KO6DZX, was camping with his family on Friday April 5th, when
their vehicle became stuck in the mud. Caleb Gustwiller, KD8TGB, and
Craig Rower, KE8QJV, were among those who picked up his weak distress
call on 28.430 MHz. The stranded ham had his radio along for the trip
and used it. Caleb said in an email to Newsline that he and other hams
who were listening -- including fellow members of the Black Swamp
Amateur Radio Club -- heard him faintly in Ohio. Those hams along with
many others posted on the Parks on the Air page on Facebook to get the
word out -- and still others called the county sheriff in Death Valley,
police in San Diego, which QRZ.com lists as the ham's address. Other
radio operators reached out to the National Parks Service police. Caleb
said it was an all-out effort from various locations.
Caleb told Newsline that the stranded ham is a relatively new licensee.
This was apparently a camping trip, not a POTA outing, but contacts
made with the Xiegu G90 and quarter-wave vertical did the trick.
According to all accounts, Rangers found the family and they were back
home safely that night.
This Ralph Squillace KK6ITB.

HAMS' EFFORTS HELP SHED LIGHT ON SOLAR ECLIPSE
PAUL/ANCHOR: The recent solar eclipse over North America gave hams a
chance to give back to science in a big way - as big as the sun itself,
you might say. Sel Embee KB3TZD has that story.
SEL: The day after the April 8th solar eclipse, logs were already
rolling in from hams and radio clubs in North America who had taken
part in the Solar Eclipse QSO Party. The party's organizer, the citizen
science group HamSCI, was already embarking on its next big challenge:
to study the logs and the results of other propagation experiments that
were taking place concurrently.
The inboxes were filling up fast, according to HamSCI's public
information officer Ed Efchak, WX2R. Ed told Newsline in a phone call
one day later: [quote] "We are certainly very very happy with
yesterday. A lot of people were on the air who understood that from the standpoint of science you have to populate to propagate." [endquote]
That population included the Suffolk County Radio Club, W2DQ, which set
up a Field Day-style operation outside an eastern Long Island library
where it operated SSB and FT8. It was also a chance to educate visitors
as club vice president Ed Wilson N2XDD explained the hams' roles in the ionospheric studies.
Meanwhile, HamSCI reported that WSPR data was already coming in from a concurrent event, the Gladstone Signal Spotting Challenge. He said
valuable results were collected as well from HamSCI's personal weather stations, the time-delay-of-arrival experiment and the medium-wave
recordings experiment.
Conclusions are, of course, a long way off -- but visitors to
Hamvention in Ohio next month will be hearing more of what's to come.
This is Sel Embee KB3TZD.
PAUL/ANCHOR: If you were involved in the QSO Party and haven't already
done so, upload your logs in .ADI or Cabrillo format, following the
link in the text version of this week's Newsline script at

NASA IDENTIFIES MEMORY CHIP THAT GARBLED VOYAGER'S DATA
PAUL/ANCHOR: Scientists at NASA have identified a damaged memory chip
that compromised Voyager 1's transmissions. We have more details from
Travis Lisk N3ILS.
TRAVIS: NASA engineers are confident they have traced the source of the
garbled data that was coming from the deep-space probe, Voyager 1.
According to the NASA website, one of the on-board computers was found
to have corrupted memory and that a single chip within the Flight Data Subsystem failed, causing this to happen. Since November any science
and engineering data sent to Earth has been garbled. Engineers were
able to link the small percentage of corrupted data to that single
memory chip.
Whether the failure was the result of wear and tear after 47 years of
flight -- or something else -- NASA engineers are now hopeful that they
can fashion an alternate method of keeping Voyager 1 on the job.
This is Travis Lisk N3ILS.

WEST VIRGINIA BROADCAST TOWERS DESTROYED IN WINDSTORM
PAUL/ANCHOR: This year has not been kind to broadcast radio towers in
the United States. The latest towers to be destroyed are in West
Virginia but this time it was by an act of nature - a fierce windstorm
with gusts of up to 90 mph. Jim Damron N8TMW has that report.
JIM: High winds have destroyed two of the four towers serving the West
Virginia MetroNews network's flagship radio station, WCHS-AM and its
sister FM station. WCHS, a news, talk and sports broadcaster, is known
as "The Voice of Charleston."
The AM radio station, which broadcasts on 580 kHz with a 5 kw signal,
is the Primary Entry Point Emergency Alert System for West Virginia.
Its programming serves the southern and southwestern part of the state.
The tower damage also affected AM station WSWW, which broadcasts on
1490 kHz. That station, an ESPN radio affiliate, returned to its
regular sports programming a day later.
A pair of FM translators also broadcast the stations' signals on 95.7
MHz and 104.5 MHz.
A report on the Radio World website showed photos of the wreckage.
Questions remained on how or when the towers would be replaced.
On a personal note, I had the privilege of working at WCHS radio
several years ago.
This is Jim Damron N8TMW.

PRESENTERS NEEDED FOR GNU RADIO CONFERENCE
PAUL/ANCHOR: Fans of open-source software for radio will be attending a conference later this year and presenters are needed, as we hear from
Andy Morrison K9AWM.
ANDY: The 14th annual conference focusing on the free, open-source
software development tool known as GNU Radio is looking for presenters. Developers and users from around the radio community are being invited
to Knoxville, Tennessee in September to share papers, presentations,
projects - and even to pose some questions - to fellow radio operators, researchers and educators. The development toolkit has been employed
everywhere -- from amateur radio to industry and government -- to be
paired with software-defined radio as well as simulated radio
environments.
Previous conference topics have included GNU radio's role in
atmospheric research, amateur radio, citizen science and channel
modeling. Proposals are due no later than June 17th. The conference is scheduled to start on the 16th of September. Visit g n u radio dot org (gnuradio.org) for details.

SILENT KEY: PUBLIC SERVICE ADVOCATE ANGUS JOE MACPHERSON, VE1CH
PAUL/ANCHOR: A longtime radio amateur who had been active as a leader
and educator in the world of public service in Canada has become a
Silent Key. We hear about him from Dave Parks WB8ODF.
DAVE: Angus Joe MacPherson, VE1CH, died on April 6th of colon cancer at
the Palliative Care Unit of the Victoria General Hospital in Halifax,
Nova Scotia. First licensed in 1963 with the callsign VE1AHC, Joe
enjoyed an amateur radio career that was complemented by his many
professional and volunteer roles as a communicator in public service.
Joe was a veteran of the Royal Canadian Navy, which he had served as a radioman.
Later, he served as volunteer telecommunications officer with the
Canadian Red Cross and was a visiting instructor at the Canadian
Emergency Preparedness College in Ontario. He retired from Industry
Canada, formerly known as the Department of Communications, where he
had worked in the Cable TV Section and Radio Regulatory Division. He represented the department on NATO's Civil Communications Planning
Committee, many of them in Europe. In 2002, he became first vice
president of Radio Amateurs of Canada.
Joe was 81.

3-D RF FILTERS SEEN AS FUTURE FOR WIRELESS
PAUL/ANCHOR: Scientists have found a way to save space and increase
performance in wireless devices by using 3-D RF filters, as we hear
from Kent Peterson KC0DGY.
KENT: A Florida researcher has developed three-dimensional RF filters
that may one day save space inside smartphones and IoT devices, leaving
more room for batteries and someday paving the way for 6G wireless
devices operating in the terahertz range.
The researcher, Roozbeh Tabrizian of the University of Florida in
Gainesville, calls RF filters [quote] "the entire backbone of wireless systems." [endquote]
Writing earlier this year in the journal, Nature Electronics, the
Florida research team explained how the 3-D filters were developed to
take the place of the more commonplace flat resonators which have
varying thicknesses depending upon the wireless frequencies they are
using. By comparison, the 3D resonators, known as ferroelectric-gate
fin, or FGF, are able to handle frequencies between 3 GHz and 28
The research team has already manufactured several of them. This is
Kent Peterson KC0DGY.

HAMS IN SPAIN GET PRIVILEGES ON 8 METRES
PAUL/ANCHOR: Hams in Spain recently got good news from the regulator:
They have privileges on 40 MHz.
JEREMY: Amateurs in Spain have been given access to the 8-metre band
for the next 18 months, joining the hams in other countries such as
South Africa, Slovenia, Lithuania, Denmark and Ireland, who also enjoy operational or propagation research privileges on 40 MHz.
In Spain, radio operators may use a maximum PEP of 25w for
transmissions on 40.650 to 40.750 MHz. The announcement was made by the country's Secretary of State for Telecommunications and Digital
Infrastructure, which granted the permission after advocacy from the
URE, the national association for radio amateurs in Spain. Hams in
Spain may only transmit from the fixed location to which their licence
is assigned and before doing so for the first time, must notify the telecommunications authorities.
This is Jeremy Boot G4NJH.

KICKER: YL CREATES APPLE APP TO PUT PARKS ON THE MAP
PAUL/ANCHOR: Our last story for this week takes us to Australia where
an enterprising YL has given a gift to iPhone and iPad users who felt a
bit left out in the woods when they were doing portable activations. We
hear about her from Graham Kemp VK4BB.
GRAHAM: Parklands and summits are anything but a wilderness for Sue
Southcott, VK5AYL. For her, inspiration grows abundantly under the
canopy of trees. The retired computer programmer is the author of a
free app in use by iPhone and iPad owners in Australia and New Zealand.
They make use of it to view and create spots, alerts and logging for
SOTA, POTA, HEMA, WWFF, SHIRES and Silos on the Air. She introduced the
app, known as Parks & Peaks, at a meeting of the Wireless Institute of Australia in 2017.
Creating it did not come easily at the time for Sue, who was still
employed as a PC programmer - and whose knowledge of Apple devices only included a few basics about their programming language known as Swift.
So she did her homework on nights and weekends to learn it, with an eye
toward filling the need for a complementary app already available to
Android users.
She's currently working on Version 4 and at some point would like to
release an international version.
Best of all, Sue isn't just a programmer, she's an activator who gets
to field test her own creation. One of her last activations was near
the Pinnacles, spectacular limestone structures on Western Australia's
Coral Coast. Needless to say, both the app and the activation were a
success.
This is Graham Kemp VK4BB.
