MOBILE BROADBAND PROVIDER SEEKS AMATEUR FREQUENCIES FOR SATELLITES

PAUL/ANCHOR: Our top story takes us this week to Washington, D.C. where the
Federal Communications Commission has received a request from the 5G broadband
service provider AST SpaceMobile to modify its license so that it can transmit
on the portion of the 70cm band used by amateur radio. The Texas-based company
is seeking the frequencies between 430 and 440 MHz for telemetry, tracking,
and telecommand between ground stations and its satellites. At the same time,
the company is seeking FCC approval for its operation of 248 low-earth orbit,
non-geostationary satellites. It is presently licensed for five.

The company's request to use the 70cm band is not insignificant: In 2023, the
German regulator, BNetzA [pronounced: BEE NETS EH] ordered AST SpaceMobile to
shut its operations when in range of the country, citing harmful interference
that violated ITU regulations. In March of 2024, the company said it had
"updated" its constellation's filings with the ITU and the FCC. It also
reduced some of its power levels and changed the heights of its orbits,
according to the Advanced Television website.

AST SpaceMobile is a rival of SpaceX, which operates the StarLink satellite
constellation, which is testing direct-to-cell with T-Mobile.
 
Earlier this year AT&T and AST SpaceMobile received FCC permission to test
direct-to-cellular satellite connectivity. 

Public comments are due by July 21st.

LOGBOOK OF THE WORLD GOES OFFLINE FOR UPGRADES

PAUL/ANCHOR: The ARRL has been busy with much more than Field Day. In fact,
just as Field Day gets under way, Logbook of the World will be moving to a
cloud-computing platform and getting some technical upgrades. Jack Parker
W8ISH has those details.

JACK: Just as hams were making their final preparations for ARRL Field Day
here in the US and in Canada, the ARRL was scheduling downtime for Logbook of
the World, beginning on June 27th. The ARRL called the process part of the
[quote] "ongoing modernization of the ARRL systems infrastructure." [endquote]
When completed, the system is to be fully operational on the cloud. The ARRL
said the move will ensure that users are protected from physical and
network-based security risks.

The last major service disruption for LoTW was last year, when it was one of
several ARRL services that were compromised by a ransomware attack. The ARRL
announced its return to service not quite two months later, on July 1st.
 
In making the announcement of this year's upgrade, CEO David Minster, NA2AA
said on the ARRL website that LoTW would return to full online operations on
the 2nd of July -- or sooner, if possible.

This is Jack Parker W8ISH.

SATELLITE PAINT EXPERIMENT TACKLES 'LIGHT POLLUTION'

PAUL/ANCHOR: The paint that BMW used six years ago on one of its cars as an
experiment, is now being looked at as a way to reduce light-pollution from
satellites that has been plaguing radioastronomers. Randy Sly W4XJ has the
details.

RANDY: What is blacker than black? It's the super black paint known as
Vantablack and its creator, Surrey NanoSystems, designed it to absorb 98
percent of light. BMW tested it out on one of its crossover model X6 cars just
as an experiment in 2019. According to Space.com, the paint reflects only 2
percent of visible and infrared light.

Now AMSAT-UK is preparing to launch Vantablack on its Jovian-1 CubeSat mission
to test its ability to avoid interference with space telescopes. The Jovian-1
goes into space sometime next year. Attendees at this year's AMSAT-UK
Colloquium in October can expect to learn more about this adventure in
light-pollution reduction.

Meanwhile if things work out, Vantablack might provide a solution for the
private satellite constellations that researchers say have been interfering
with ground-based astronomical research. As more satellites are being sent
into space, that's not insignificant to observatories here on the ground

This is Randy Sly W4XJ.

UNHEARD-OF DATA SPEED REPORTED FROM CHINESE SATELLITES

PAUL/ANCHOR: Scientists in China are claiming they have achieved unprecedented
speed in sending data from satellites - using low-power laser. Jim Meachen
ZL2BHF has that story.

JIM: In a development that some observers say could someday replace
satellites' reliance on RF, scientists in China are claiming that they have
developed a transmission method using minimal laser power. The method is known
as "AO-MDR synergy" and utilises a 2-watt laser. Scientists at Peking
University and the Chinese Academy of Sciences have said that by employing
this technique, they recently accomplished a 1 Gigabit-per-second data
transmission to Earth from a geostationary satellite.

Researchers praise the development, adding that it addresses a common
challenge for satellite downlinks - the distortion caused by atmospheric
turbulence. The developers of the process said that "AO-MDR" addresses this by
stabilizing the laser signal even when it faces atmospheric turbulence. The
technique combines  Adaptive Optics and Mode Diversity Reception.

This is Jim Meachen ZL2BHF.

FROM THE BBC, FOR ANTARCTICA'S EARS ONLY

PAUL/ANCHOR: Scientists on the frozen Antarctic continent got a good warm
feeling listening to the shortwave radio recently. Graham Kemp VK4BB tells us
why.

GRAHAM: The shortwave broadcast wasn't aiming for big global listenership.
Indeed, there were perhaps only a few dozen pairs of ears for whom the special
programme was intended. Still, the BBC's Antarctic Midwinter Broadcast is a
shortwave tradition Down Under. This year, its 70th anniversary year, was no
different. Scientists and support staff of the British Antarctic Survey Team
were tuned in on the 21st of June to hear welcoming messages from home -
including a pre-recorded greeting from King Charles, the first monarch to
participate in the tradition.

The show only lasted a half-hour but has been a big part of a midwinter at
British research stations on the frozen continent for decades.

This is Graham Kemp VK4BB.

YOUNGSTERS ON THE AIR CAMP GEARS UP IN EUROPE

ANCHOR: Here in the US, the Youth on the Air Americas Camp has just wrapped up
in suburban Denver, Colorado. Soon, it will be France's turn to host eager
young amateurs. Jeremy Boot G4NJH has the details.

JEREMY: Youngsters on the Air - also known this year as YOTA France - is
getting ready for its 13th edition. The camp will be taking place at the
Chateau de Jambville near Paris from the 18th through to the 25th of August.
It is being hosted by the French national amateur radio society, Rseau des
metteurs Franais or REF.

Although the camp serves primarily youngsters from throughout IARU Region 1,
guest campers will be welcomed from Regions 2 and 3. About 100 young amateurs
attend these camps each year, participating as teams representing their
countries. Previous YOTA summer camps have been held in such countries as
Czechia,  Hungary, Croatia, Bulgaria, South Africa and Great Britain.

SWEDEN'S GRIMETON RADIO STATION TO SEND JUBILEE MESSAGE

PAUL/ANCHOR: In Sweden, the Grimeton Radio Station is marking its jubilee year
in the most appropriate way possible - can you guess how? Jeremy Boot  G4NJH
has some answers.

JEREMY: The Jubilee Year for the Grimeton Radio Station in Sweden is well
under way, having begun last December. The highest point of the year, however,
will come on the 2nd of July - the exact date, 100 years ago, that the
station's 200kW alternator sent a message across the Atlantic Ocean for
receipt by the US president, Calvin Coolidge. The message reached the
receiving station in Riverhead, New York - on Long Island - and the president
had a reply sent, praising the new broadcaster and sharing his hopes for good
relations between Sweden and the US.

July 2nd is nearly here and the 100-year anniversary of that historic message
is being celebrated with a telegram to be transmitted from the station on 17.2
kHz using CW at 0900 UTC. The station will be using the original callsign,
SAQ, .

The broadcast can be heard on a receiver with VLF capability and will also be
live streamed on YouTube.

In the meantime, hams wishing to make contact with the amateur radio station
SK6SAQ in CW or SSB should be listening on 80, 40 and 20 metres.

LIFESAVING SKILLS LEARNED ATOP SOME SOTA SUMMITS

PAUL/ANCHOR: Being a SOTA activator has given one ham in Australia much more
than memorable QSOs, spectacular summit views and some outdoor adventures. It
has provided him with some lifesaving skills, as we hear from Jason Daniels
VK2LAW.

JASON: As record-breaking fires consumed huge sections of the Canadian
province of Alberta, Wade Smith VK1MIC, was preparing for an activation that
would take him into the heart of the destruction. As captain of the
communications brigade in the New South Wales Rural Fire Service, Wade
responded to Canada's request by traveling from Sydney with the Australian
contingent. Wade added his specialised skills in air radio and dispatch to
assist the joint Australian-Albertan Incident Management Team operating in the
remote northern region of Alberta.

Facing the challenge of several large fires raging, Wade and his team handled
more than 500 radio calls daily. The fire-fighting effort mustered more than
20 aircraft involved in operations across several large fires,

Wade, who is also the VK1 SOTA Association Manager, said his years of SOTA
experience have served as great practice for staying focused, handling several
stations at once and managing fast-moving communications pile-ups. He said
[quote]" "These same skills are directly transferable to coordinating air
operations under pressure." [endquote]

The fires posed hazards on the ground locally as well as for the air quality
in much of North America. Weather experts attribute the conditions in the
region to an ongoing trend of dry, warm conditions that have been worsened by
the global climate crisis.

KICKER: MYSTERY SIGNALS FROM THE GREAT BEYOND?

PAUL/ANCHOR: It?s pretty well-known that some scientists study outer space in
search of extraterrestrial life ? but what happens when researchers believe
they have instead stumbled upon...the afterlife? Kent Peterson KC?DGY tells us
what did - and didn?t -- really happen in this week?s final story.

KENT: Rest in peace, NASA Relay 2 satellite. The spacecraft was one of two
launched at different times in the 1960s by the US space agency to serve as
experimental communication satellites. Unlike NASA?s Relay 1, which
transmitted American TV signals into Japan and Europe, Relay 2 was used for
barely a year. It stopped operations in 1965 and its transponders were
believed to have died in 1967 

The key word here is ?believed? - because one year ago this month, researchers
in Australia were certain they'd heard Relay 2 returning radio pulses to earth
in much the same way some so-called "zombie" satellites, like the famous AMSAT
OSCAR-7, have been known to do.

In this case, no seances or Ouija boards were necessary to understand this
message from The Great Beyond. Some scientists theorize that the pulses came
from the discharge of electrostatic energy, or ESD, that had built up on Relay
2 over time. Another theory is that its impact with a micrometeoroid released
a cloud of plasma capable of sending such a signal.

Researchers plan to study both ESD and the micrometeoroid effect in the hope
of a better understanding in the future. It's not about alien life or
afterlife, then: Just breathing new life into solving more mysteries of space.

This is Kent Peterson KC?DGY.
