FCC REOPENS AFTER HISTORIC US GOVERNMENT SHUTDOWN

STEPHEN/ANCHOR: Our top story this week takes us to Washington, D.C. where the
US Federal Communications Commission has gone back to work. It has quite a bit
of catching up to do, as we hear from Randy Sly W4XJ.

RANDY:  After a 43-day shutdown that left 80 percent of the staff furloughed at
the FCC, the agency has reopened and begun tackling a serious backlog. As a
result, the commission has announced new deadlines for many of its filings,
including amateur radio licenses.

In a public notice released on November 17th, the FCC said that renewal filings
for amateur radio, GMRS and other personal radio licenses now have a deadline
of March 5th, 2026. This deadline relates to all renewal filings that were due
on the 1st of October through - and including - the 5th of March, 2026. Holders
of expired licenses who now have their renewal-filing deadlines extended will
be able to continue operating meanwhile, as per FCC rules.

The nation's longest government shutdown ended with lawmakers' agreement on a
bill that maintains funding for federal agencies and programs -- at least until
January 30th, 2026, when the country could face a replay of the closure.

HUNGARIAN AMATEURS CELEBRATE BROADCAST CENTENNIAL

STEPHEN/ANCHOR: There was a time in Hungary when the simple act of a radio
broadcast - or listening to one - was a crime. Now it's a special event, as we
hear from Jeremy Boot G4NJH.

JEREMY: The transmission of radio signals of any kind was merely an
experimental pursuit in Hungary until late 1925 - and listening to radio over
the air, or having privately owned amateur equipment - was forbidden. All of
that was to change later that year with the start of the first Hungarian public
radio broadcast on 1st December. One hundred years later, amateurs in Hungary
are celebrating Hungarian Radio Day, when radio was permitted there.

Nine special callsigns - all beginning with "HG100" - are on the air throughout
December until 31st, operated by amateurs from the Hungarian Radio Amateur
Society and the Honfy Jozsef Radioclub. Contacts have been made since the 15th
of November on CW, SSB and the digital modes on 160 to 10 metres. The operators
are also making use of the QO-100 satellite.

The Hungarian Radio Amateur Society website has a full list of the nine
callsigns and more details about how to receive a commemorative certificate.

This is Jeremy Boot G4NJH.

INDIAN AMATEURS STUDY IMPACT OF SEASON'S TRANSITION

STEPHEN/ANCHOR: Youve heard of Winter Field Day and youve heard of the
traditional ARRL Field Day held in the summer in the northern hemisphere. Jim
Meachen ZL2BHF takes us to West Bengal, India where amateurs have just
completed a season transition field day.

JIM: As surely as autumn turns to winter in some parts of the world, radio
operators are curious about the impact that seasonal changes are going to have
on propagation. A recent extended field operation by a group of 17 hams from
the West Bengal Radio Club tracked those changes by getting on the air near the
Earths Tropic of Cancer. This was as much an academic exercise as a radio
exercise, as two professors from nearby universities collected data over the
30-hour period to be used in their research. 

Ambarish Nag Biswas, VU2JFA, the clubs secretary, said that Suman Patra from
Jhargram University and Ambika Ghosh from the Heritage Group of Institutions in
Kolkata are both studying disaster communications at the Indian Academy of
Communication and Disaster Management. The pair hope that analysis of the data
will show ways to improve the quality of emergency communication at this
challenging time of seasonal change. The Tropic of Cancer was chosen because
when it is summer in the northern hemisphere, the suns rays are directly
overhead. With the approach of winter, the sun is lower in the sky.

This is Jim Meachen ZL2BHF.

NEURAL CODEC CALLED 'MILESTONE' FOR DIGITAL VOICE

STEPHEN/ANCHOR: It's being heralded as a milestone in the long-overdue
evolution of speech quality for land-mobile radio systems - the use of an
adaptive neural network that replaces traditional signal processing. Andy
Morrison K9AWM has the details.

ANDY: A digital voice milestone was announced at the recent acoustics and
speech conference in Caliornia when the Free DV Project's David Rowe VK5DGR
copresented a paper describing a neural network that replaces traditional
signal processing with machine learning.

In a recent post on the FreeDV website, David called the development: [quote]
"the first known real-world deployment of a neural codec  an important
milestone that the Ham community can be proud of." [endquote] He and programmer
Jean-Marc Valin presented the details to attendees at the IEEE Signal
Processing Society conference where David said it was well-received.

Instead of using the fixed algorithms of traditional digital voice, the FreeDV
Radio Encoder, known as RADE V1, employs fully adaptive machine learning,
producing a higher-quality result, developed using open source software.

Writing as a guest contributor to the Amateur Radio Digital Communications
website in October, David noted that the technology [quote] "provides
unprecedented speech quality and robustness for VHF/UHF land mobile radio
applications." [endquote] The FreeDV project has been doing t his work with 
grant support from ARDC.

This is Andy Morrison K9AWM.

NASA STUDIES DISABLED DEEP-SPACE NETWORK ANTENNA

STEPHEN/ANCHOR: If you think you sometimes have more than your share of antenna
troubles, listen to this report from Ralph Squillace KK6ITB. He tells us about
NASA's plans to get a damaged deep-space network antenna back in action.

RALPH: The US space agency NASA is taking a close look at the serious damage
that disabled the largest antenna at its Deep Space Network site in California
two months ago. The 230-foot antenna, which tracks near-Earth asteroids and
communicates with NASA's interplanetary spacecraft, has been out of service
since the 16th of September. The antenna suffered an excessive rotation that
strained its cabling and piping and damaged its fire-suppression system, which
led to water damage and flooding, according to a report on the Gizmodo website.

The damaged antenna, prized for its sensitivity, received its first signal in
1966 from NASAs Mariner 4 mission. In preparation for Voyager 2's mission
toward Neptune, NASA upgraded the antenna's width from 210 feet, or 64 meters,
to 230 feet, or 70 meters. It communicated as well with Voyager 1 in 2012
following the spacecraft's entry into interstellar space.

Meanwhile, NASA relies on two other deep-space communication antennas. They are
located in Madrid, Spain and near Canberra, Australia.

HAMS PREP FOR PERSEIDS METEOR SCATTER EXPERIMENTS

STEPHEN/ANCHOR: Get ready for a major meteor shower next month - and a major
meteor scatter radio activity. Neil Rapp WB9VPG tells us how to get involved.

NEIL: Hams who played a part in the meteor scatter experiments conducted by
HamSCI, Ham Radio Science Citizen Investigation, during the Perseids show this
past August get another chance at action in the sky next month.

The Geminids are coming! HamSCI's experiments for these meteor showers will
take place on the 12th and 13th of December, from 0000 to 2400 UTC. Operators
are being asked to use MSK144 on 50.260 MHz and 28.145 MHz. 

HamSCI reports that the Perseids show produced more than 70 logs and files for
study and the research group is hoping for similar results this time around.
Hams are being invited to participate in the QSO Party in what is once again
described as a combination of a contest and a special event. Rules for the
activity can be found on the link in the text version of this week's newscast
at arnewsline.org

As the HamSCI website says: "Work the rocks! Decode the pings."

This is Neil Rapp WB9VPG.

2 NEW REPEATERS CREATE CRUCIAL NETWORK IN KANSAS

STEPHEN/ANCHOR: With the help of a grant, some counties in Kansas are getting
expanded coverage from new repeaters that have digital capability. Jack Parker
W8ISH has that report.

JACK: A network of repeaters is being created to expand digital amateur radio
services in the state of Kansas with the help of a $13,950 grant from Amateur
Radio Digital Communications.

The network will be accessible to hams in nine counties. The repeaters will
operate on VHF and UHF and provide linkage over the Internet through Yaesu
Wires-X, a system that provides even wider coverage. The network callsign will
be KØHYS.

Two new repeaters will be established to connect with a repeater that is
already in operation in Ellis County. The grant has been given to the Ellis
County Amateur Radio Emergency Service Group and STEM Harvest Inc., an
educational resource that focuses on helping people develop skills in
technology.

This is Jack Parker W8ISH.

WORLD OF DX

In the World of DX, Abie, AB1F is on the air as A52AA from Bhutan through to
the 5th of December, operating SSB on 40, 20, 15 and 10 metres. He may also be
heard on 80 and 160m. 

On Easter Island, a team of nine operators using the callsign 3GØYR, will be on
the air from the 26th of November through to the 3rd of December. Their four or
five stations will use all modes on all bands, concentrating on the low bands.
Listen for them in the CQ WW DX CW Contest with the callsign CEØY.

You still have time to work operators celebrating Statehood Day in Bosnia and
Herzegovina. They are on the air with the special callsign E7BOSNIA until the
25th of November, which is the oficial date of the celebration.

Visit QRZ.com for QSL and other information about these stations.

KICKER: FOR GOOGLE, A RAY OF AI HOPE FROM THE SUN

STEPHEN/ANCHOR: For our final story, we look at the future of AI -- and we
consider the sun's rays as rays of hope to power that future. Kent Peterson
KCØDGY brings us that story now.

KENT: Picture groups of satellites in a low-Earth orbit that is synchronized
with the sun, the very source of the energy that powers them. Then imagine each
satellite outfitted with AI chips doing the business of machine-learning high
above our planet. The satellites are between 100 and 200 metres apart within a
cluster that is no more than 1 kilometer wide but they have optical connections
that enable them to serve as a single data center.

This is Project Suncatcher, a vision announced by Google earlier this month. It
exists only in theory - at least for now. Google has teamed up with Planet, an
Earth-imaging company, in the hopes that the partnership can launch a so-called
"learning mission" into space in 2027 using two prototype satellites to test
the technology and the hardware.

Meanwhile, Google is working out the costs of Project Suncatcher when it
ultimately deploys: The launch alone is considered to have a prohibitive price
tag. There are also issues of aerospace engineering that need to be resolved to
keep the satellite cluster in good repair.

With AI's established reputation as a voracious consumer of energy, the company
says it was only logical to look beyond the horizon - way beyond the horizon -
to get closer to a source of power. Just what is the prospect for the success
of Project Suncatcher? Right now, you won't find that answer, even if you
google it.

This is Kent Peterson KCØDGY.
