RADIO AMATEURS RESPOND TO DEADLY FLOODS IN SPAIN

STEPHEN/ANCHOR: Our top story takes us to Spain, where hams are among the
many volunteers helping vital messages get through in a region where
people's lives have been swept away by floodwaters. Jeremy Boot G4NJH has
those details.

JEREMY: As parts of Spain were overtaken by historic flooding, two groups provided emergency radio communications through VHF/UHF repeaters in the hard-hit region. Greg Mossop, GØDUB, the IARU Region 1 emergency
communications coordinator, told Newsline that much of the response came
from R.E.M.E.R., the government's Civil Protection Radio Network, which
draws membership from the amateur community. Other hams were deployed from Emcom-Espana, the emergency communications group of the URE, the Spanish national amateur radio society, whose messages proved vital as flash floods pounded eastern Spain, trapping and killing people in the unrelenting
weather conditions.

Greg told Newsline that the regions most affected included the communities
near Valencia, Murcia and Andalusia. The IARU received its reports from Jose Antonio Mendez Rios, EA9E, the emergency spokesman for URE and the national coordinator of Emcom Espana.

Meanwhile, as officials assessed the flood damage, search parties were dispatched to seek out those reported missing.

AWARD FOR USE OF WIRELESS IN WEATHER PREDICTION

STEPHEN/ANCHOR: A prominent educator in Israel has achieved international recognition for her work in using wireless signals to aid in prediction of extreme weather, such as flash floods. We hear about her from Graham Kemp VK4BB.

GRAHAM: Hagit Messer-Yaron has been honoured by the IEEE for her work in harnessing wireless signals to collect weather data -- to serve as a
reliable predictor of floods. She was inspired to assist meteorologists who
had told her, years ago, that predictions are not always possible or
consistent when using radar, satellites and other tools. Working with a research team, she found a more reliable method using wireless
communication. The process involves use of algorithms developed by her and
her team and applied to data collected from communication networks. This technique, which was tested first in Israel, can predict flash floods by extracting the data from measurements in the difference between the
amplitude of the signals transmitted and those received. She is hoping to
apply it to communication networks globally. Her hope is that people would
be alerted well in advance of the storm and could be evacuated from affected areas sooner.

For her work, she has received the Medal for Environmental and Safety Technologies from the IEEE, where she is also a Life Fellow.

This is Graham Kemp VK4BB.

THIRD BROADCAST TOWER COLLAPSES IN US

STEPHEN/ANCHOR: In the US, another broadcast tower has collapsed - this one
in the state of Missouri -- marking the third such incident in October.
Randy Sly W4XJ has that story.

RANDY: The tower of Missouri AM radio station KRMO, 990 kHz, collapsed on
the 24th of October after one of its guy wires snapped, according to
industry media reports. The incident marked the third destruction of a US broadcast tower in October. Local media reports said that one of the co- owners, Dewayne Gandy of Eagle Broadcasting, witnessed the collapse as he
was mowing nearby. The tower was 75 years old and maintenance work had
recently been performed. While the owners make plans to restore a tower to
the site, the station is transmitting via sharing access on the KSWM-AM 940
kHz tower in Aurora, Missouri. Earlier in October, a broadcast tower
collapsed in Houston, Texas, after a helicopter crashed into it, leaving
four dead. In Albuquerque, New Mexico, station KKOB-AM was knocked off the
air after its tower was destroyed by the impact of a hot-air balloon. The
three passengers were reported safe after that incident.

DELAYED OPENING AT ARECIBO SCIENCE EDUCATION CENTER

STEPHEN/ANCHOR: A science education center at the site of the former Arecibo radio telescope is delaying its much-awaited opening to the public, as we
hear from Travis Lisk N3ILS.

TRAVIS: Following a pilot program held this summer that opened its doors to students and educators by invitation only, the scientific education and research center at the site of the former Arecibo Observatory has had its opening delayed until the new year. The National Science Foundation facility
in Puerto Rico is known as the Arecibo Center for Culturally Relevant and Inclusive Science Education, Computational Skills and Community Engagement,
or NCF Arecibo C3. It was originally scheduled to open in November.

Center administrators said the delay would provide more time for the
transport of essential equipment and preparation to make the facility more accessible. One of C3's orginal collaborators, Universidad del Sagrado
Corazon, recently ended its involvement with the center, expressing pride in its first year of work with others on the team. The university's provost
and VP for academic affairs said in a statement: [quote] "These partnerships and structures have now been successfully initiated, and the remaining institutions involved in the project will continue this important work." [endquote]

The National Science Foundation announcement said the delayed opening to the public will also allow adjustments in C3's organizational structure. Opening day is expected to coincide with the National Science Foundation's 75th anniversary. The goal of the center is to provide a place for STEM education and research that honors the historic Arecibo Observatory, which was
dismantled after its collapse in 2020.

INVESTIGATORS PINPOINT POSSIBLE ROOT OF ARECIBO COLLAPSE

STEPHEN/ANCHOR: Meanwhile, a draft report about the 2020 collapse that led
to the dismantling of the Arecibo Observatory's 305-metre telescope has pinpointed what is believed to be the root cause. A pre-publication document from the National Academies, made available to the public online, said that investigators found [quote] "unprecedented and accelerated long-term zinc
creep induced failure." [endquote] In other words, the failure occurred in
the radio telescope's cable sockets, vital components that were designed to support the 900-ton platform that was above the dish. The data analysis was conducted by the University of Central Florida and the National Science Foundation.

The telescope's construction occurred between 1960 and 1963. Investigators believe that the sequence of events leading to the collapse may have begun
with Hurricane Maria, which hit the telescope as a Category 4 in 2017. The report noted that inspections before the storm found the zinc leading edge
to be intact - but in late 2018 and early 2019 cable slippage was detected.

OLDER S-BAND TECHNOLOGY KEEPS VOYAGER 1 TRANSMITTING

STEPHEN/ANCHOR: Another crisis was resolved aboard the Voyager 1 deep space probe by turning back the clock on technology. Kent Peterson KCØDGY tells us what happened.

KENT: For Voyager 1, there was another disturbing incidence of radio silence all over again. A shutdown in October of the X-band radio transmitter left
the space probe unable to communicate with the Deep Space Network. The
mission team linked the problem to a command that had been sent to turn on
one of Voyager's heaters. The team believes the command somehow activated
the spacecraft's fault-protection system which conserves its power That
lowered the rate of data transmission and shut off the X-band transmitter, instead engaging the S-band transmitter.

Recounting the sequence of events in the Voyager Blog, NASA's Tony Greicius wrote that S-band transmission, which has a fainter signal than X-band and consumes less power, had not been used by the space team since 1981. S-band operates on frequencies between 2 and 4 GHz whereas X-band uses frequencies
in the range between 8 and 12 GHz. The NASA blogger wrote: [quote] "The
flight team was not certain the S-band could be detected at Earth due to the spacecraft’s distance, but engineers with the Deep Space Network were able
to find it.” [endquote] The old S-band transmitter has turned in a reliable performance since October 24th, even from the distance of more than 15
billion miles, or 24 billion kilometres, from Earth, and will remain in use while the team continues its troubleshooting.

According to the blog, [quote] "it may take days to weeks before the team
can identify the underlying issue that triggered the fault protection
system." [endquote]

JAPAN LAUNCHES SPACE SATELLITE MADE OF WOOD

STEPHEN/ANCHOR: NASA has launched LignoSat, a wooden satellite built by Japanese researchers. It was successfully sent to the International Space Station on Tuesday, November 5th, headed to the International Space
Station. Newsline first reported on its development in 2021 as a partnership between Kyoto University and a Japanese home-building company, Sumitomo Forestry. It is expected to be released into orbit about 250 miles, or 400
km, above the Earth. LignoSat is an experiment using space-grade wood to
build environmentally friendly satellites. Meanwhile, New Zealand has been
busy with its WISA Woodsat, a 1-kilogram amateur radio satellite built in Finland. When launched by a rocket, it is expected to reach an orbit about
310 to 340 miles - or between 500 and 550 km above Earth. The microsatellite has already completed a test flight in the stratosphere, 30 km above Earth, aboard a weather balloon.

HAMSCI RECEIVES 0.8M GRANT FOR IONOSPHERIC STUDIES

STEPHEN/ANCHOR: A 0.8 million grant has been given to HamSCI for it
continued work studying the ionosphere. Andy Morrison K9AWM tells us what's planned next.

ANDY: The citizen science investigators of HamSCI have received 0.8 million
in additional support from the National Science Foundation to support their ongoing studies of the ionosphere. The announcement was made by HamSCI
founder Nathaniel Frissell, W2NAF, who said the funding would be used for various kinds of equipment to measure different aspects of the ionosphere's behavior. They include 10 WSPRSonde transmitters to be a source of GPS- stabilized HF beacon signals. The funding will also support a network - now
in development - comprising 30 standardized receive stations that can
observe HF Doppler shifts, WSPR transmissions, VLF transmissions, the geomagnetic field and natural radio emissions. Nathaniel said the network
being established will be [quote] "the only wide-spread, coordinated high frequency, very low frequency and ground magnetometer measurement network
that is distributed primarily across the midlatitude region." [endquote]

According to an announcement by the University of Scranton, where Nathaniel
is an associate professor in physics and engineering, he will be the lead principal investigator of the collaborative work done under the grant with researchers at Case Western Reserve University, the University of Alabama
and the New Jersey Institute of Technology.

These projects are a continuation of the ongoing work by HamSCI which
involved amateur radio participation in Solar Eclipse QSO Parties this year
and last year. Hams were able to contribute data that helped researchers
better understand the impact the annular solar eclipse and the total eclipse had on the ionosphere.

HAM RADIO TO GIVE ALASKAN ISLAND GREATER CONNECTION

STEPHEN/ANCHOR: In Alaska, an island community off the coast of the mainland has become a little bit less of an island now because of amateur radio.
George Zafiropoulos KJ6VU has that story.

GEORGE: Members of the Petersburg Volunteer Fire Department have always been ready to respond from their fire hall if an emergency strikes their island overlooking Frederick Sound. The hard work and generosity of one local ham
has just made the fire hall a whole lot more ready. Gary Treffry WL7LV, has donated two transceivers, tuners and antennas, along with wires, power
supplies and an amplifier and established an amateur radio station there.
The goal isn't just enhanced emergency response but the creation of a new
local ham radio club based at the fire hall.

Communication is key in this part of the northernmost state of the US. Emergency Services Director Aaron Hankins told the local paper, The Pilot: [quote] "We are islands ... there's no one we can just drive down the road
and get communications from but we hope to have that added capability." [endquote]

There are already some resources locally. Alaskan hams are part of the
Amateur Radio Emergency Service, or ARES. More than 100 hams also
participate in the Alaska-Pacific emergency preparedness net, or A-P Net,
where Gary is a member. Aaron Hankins said he is hoping to see more hams get involved at the fire hall after the project is completed. He added: [quote]
"I hope that we never have to use his contribution in an emergency fashion,
but we'll definitely be very glad to have this capability if the need
arises." [endquote]

HAMVENTION ANNOUNCES THEME: "RADIO INDEPENDENCE"

STEPHEN/ANCHOR: With Hamvention 2025 set for the weekend of May 16th, the organizers are asking prospective attendees to ponder the question of what "radio independence" means to them. That is, in fact, the theme for the convention in Xenia, Ohio. In announcing the theme, the Hamvention team says [quote] "In the course of history radio has been heavily regulated and, in
some instances, banned altogether. We are fortunate to enjoy these freedoms, and for us at Hamvention we are proud of our Radio Independence. What does Radio Independence mean to you?" [endquote]

Hopefully there will be many answers found in the workshops, seminars and eyeball QSOs at the Greene County Fairgrounds.

KICKER: A ONCE-SLEEPY SATELLITE MARKS 50 YEARS IN SPACE

STEPHEN/ANCHOR: We end this week's report with a story, one that could be called Sleeping Beauty - or perhaps more correctly, Rip Van Winkle. Either
way, this story really is a sleeper - as you'll hear from Neil Rapp WB9VPG.

NEIL: This is no fairy tale. It's a story that begins on November 15th of
1974 with the launch of a little satellite, a SmallSat called AO-7. For six
and a half years it delighted amateur radio operators who made use of it worldwide. As time went on, however, AMSAT knew that it would soon be time
to say good-bye: By 1980, the cells in the satellite's NiCad battery began
to fail over a period of weeks into 1981. Thus began the Big Sleep of
SmallSat AO-7. That is, until its sudden awakening, which AMSAT said could
only have been possible if the battery developed an open circuit.

Still, there was no mistaking this wakeful voyager. In 2002, Perry Klein,
W3PK, AMSAT's first president, received a phone call from satellite
enthusiast Pat Gowain, G3IOR [G Three EYE OH Arr], alerting him to the fact that he'd just picked up Morse Code telemetry on AO-7's former beacon frequency. It was confirmed. Soon other hams heard it too. Like Rip Van
Winkle - in the classic short story by Washington Irving - satellite AO-7
had officially ended a slumber that was two decades long.

Throughout November, AMSAT News Service will be honoring this oldest active amateur radio satellite with articles retelling its exciting story. Visit
the link in the text version of this week's newscast at arnewsline.org. We promise - you'll have no trouble staying awake.

This is Neil Rapp WB9VPG.
