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 0-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

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 KCØDGY.
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.

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.

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.
