    DEAF PUPILS SET TO SPEAK WITH ISS CREW MEMBER IN A WORLD-FIRST
    EVENT

    Amateur Radio on the International Space Station (ARISS
    <http://www.ariss.org>) will offer a group of pupils at the Mary Hare
    School <https://www.maryhare.org.uk/> for deaf children in Berkshire,
    England an opportunity to speak with an astronaut via amateur radio.
    The contact is expected to take place sometime during October 10 - 17.
    Mary Hare School, with Pippa Middleton as its Ambassador, is the
    largest school for the deaf in the UK. The event will mark the first
    time an ARISS contact has been arranged with a school for deaf youth.

    "It is a very exciting event -- a world first for deaf pupils," said
    Alex Ayling, a science teacher at the school. "I think it is very
    important to our deaf pupils, as it shows whatever your challenges with communication, there is no limit to what you can achieve. The sky is
    not the limit."

    Ciaran Morgan, M0XTD, ARISS operations lead for the UK, said that
    technical aspects of the radio contact are being handled by the
    ARISS-UK team. The Newbury and District Amateur Radio Society (NADARS)
    will provide "the amateur radio experience" for the students, through
    ham radio events and activities at the school. Lessons related to ARISS
    include a crystal radio, electricity and circuits, forces, energy,
    sound, electromagnetism, space and space exploration, the ISS, and
    rocketry.

    During September, the school has been conducting a competition,
    inviting students to enter questions from one of five categories --
    science in space, space technology, living in space, space
    communication, and Earth from space. The school staff will pick the 10
    best questions, and those students will be invited to ask their
    questions. The astronaut's response will then be rendered as text for
    the students.

    At the school, an expected audience of 250 socially distanced
    spectators will be able to see the radio contact firsthand. The
    remaining students and audience members will be linked in via a web
    feed.

    Amateur radio equipment has been on board the ISS for more than 20
    years, and most astronauts hold ham radio licenses. A live web feed
    will be available.

    Mary Hare School educates some 240 profoundly and severely deaf
    children, aged 5 - 19, each year.

    In the US, ARISS is sponsored by NASA, the ISS National Laboratory,
    ARRL, and AMSAT <http://www.amsat.org>. -- Thanks to UK News

    AMATEUR RADIO VOLUNTEERS ASSIST IN MAJOR US CYCLING EVENT

    Some 115 amateur radio volunteers from five states turned out on
    September 11 to support communication for the longest single-day
    US-sanctioned cycling event, LoToJa <https://lotoja.com/>, now in its
    39th year. Starting in Logan, Utah, the 203-mile course ends in Jackson
    Hole, Wyoming -- taking cyclists through northeastern Utah,
    southeastern Idaho, and western Wyoming in the process. The race
    attracts thousands of applicants, and upward of 2,000 of them are
    selected to compete. Some 1,700 competed in this year's LoToJa. The
    event's cyclists and sponsors have contributed more than $2 million for Huntsman Cancer Foundation. Hams from multiple ARRL-affiliated clubs in
    Utah, including Golden Spike <https://www.ubetarc.org/>, OARC <http://www.ogdenarc.org/>, and UVARC <https://uvarc.club/>,
    participate. The group does "neutral wheel" support (which substitutes
    wheels and equipment in the event of a failure) as well as first aid,
    as needed, and provides communications from start to finish. The race
    deploys four command centers and multiple repeaters.

    "This year's race will have 600 course volunteers, which includes 150
    ham radio operators [and helpers] from the Bridgerland Amateur Radio
    Club. They provide uninterrupted communication throughout LoToJa's
    mountainous and remote terrain," Race Director Brent Chambers told <https://www.cachevalleydaily.com/news/archive/2021/09/08/cyclists-gather-in-logan-for-39th-annual-lotoja-saturday/#.YUoKgFVKiUl>

    the Cache Valley Daily.

    "We take two portable repeaters to the top of mountains, and we deploy
    multiple APRS digipeaters," explained Kevin Reeve, N7RXE, the
    coordinator of amateur radio operators and communication systems for
    LoToJa. "All ham vehicles run APRS, and we have APRS and a radio
    operator with the race director and race official. Our goal is to help
    the cyclists, support crews, and families have a safe and enjoyable
    event."

    Ted McArthur, AC7II, heads the communication infrastructure team for
    the LoToJa hams. In all, nine repeaters and several simplex frequencies
    are used throughout the event, and APRS plays an important role.

    "With [an increased] number of mobile vehicles needed to meet a growing
    event, Net Control stations were spending a lot of radio time asking
    for position reports," McArthur said. "We needed the air time for real
    traffic, like helping cyclists, emergencies, and other critical
    traffic."

    "LoToJa is such a great event for amateur radio operators to
    participate in," said Tyler Griffiths, N7UWX. "It is the ARES [Amateur
    Radio Emergency Service®] radio operator's dream event. We know where
    it starts, we know where it ends, but everything that happens in
    between is different from year to year."

    ARRL PODCASTS SCHEDULE

    The latest episode of the On the Air podcast (Episode 21) features a
    discussion with Steve Goodgame, K5ATA, about the new edition of The
    ARRL Handbook and how it can be useful to new hams.

    The latest edition of Eclectic Tech (Episode 43) features a chat with
    Glen Popiel, KW5GP, about his new ARRL book More Arduino for Amateur
    Radio.

    The On the Air and Eclectic Tech podcasts are sponsored by Icom. Both
    podcasts are available on iTunes (iOS) and Stitcher (Android) as well
    as on Blubrry -- On the Air <https://blubrry.com/arrlontheair/> |

    PAST AMSAT PRESIDENT AND DIRECTOR, AND AMATEUR SATELLITE PIONEER
    TOM CLARK, K3IO, SK

    AMSAT-NA Past President and ham radio satellite and digital pioneer Tom
    Clark, K3IO (ex-W3IWI), of Columbia, Maryland, died on September 28
    after a short illness and hospital stay. An ARRL Life Member and ARRL
    Maxim Society and Diamond Club member, he was 82. Clark's
    accomplishments are legendary, and he left a lasting footprint on the
    worlds of amateur radio satellites and digital techniques.

    "His longtime technical achievements, mentoring to others, and
    technical leadership will be missed by his many peers and friends the
    world over," said Bob McGwier, N4HY.

    To honor Clark, AMSAT has rebranded its upcoming annual gathering as
    The 2021 AMSAT Dr. Tom Clark, K3IO, Memorial Space Symposium and Annual General. It will take place on October 30 via Zoom. (AMSAT members may
    register <https://launch.amsat.org/> to attend via AMSAT's Member
    Portal.) The event will be livestreamed <https://youtu.be/RTvcceM7Tz0>
    on AMSAT's YouTube channel.

    A founding member of Tucson Amateur Packet Radio (TAPR), Clark was a
    cofounder of the TAPR/AMSAT DSP Project, which led to software-defined
    radio. He was a leader in the development of the AX.25 packet radio
    protocol. Clark served as AMSAT's second president, from 1980 until
    1987. He also served on the AMSAT and TAPR Boards.

    In concert with McGwier, Clark developed the first amateur DSP
    hardware, including a number of modems. He developed the uplink
    receivers and the spacecraft LAN architecture used on all the Microsats
    (Oscars 16, 17, 18, 19, 26, 27, and 31). McGwier said it was Clark who convinced him in 1985 that the future lay in DSP.

    "We started the TAPR/AMSAT DSP project, and it was announced in 1987,"
    McGwier recounted. "We showed in our efforts that small stations with
    small antennas could bounce signals off the moon, and using the power
    of DSP, we could see the signals in our computer displays." This led to
    the software-defined transponder (SDX) for satellite work, including
    ARISSat and AMSAT's Phase 3E.

    Clark received a doctorate in astro-geophysics from the University of
    Colorado. He went on to serve as Chief of the Astronomy Branch at NASA
    Marshall Space Flight Center and was a Senior Scientist at NASA Goddard
    Space Flight Center, where he was principal investigator for the Very
    Long Baseline Interferometry (VLBI) activity.

    In 2005, he became the first non-Russian to be awarded the Special
    Medal of the Russian Academy of Sciences for his contributions to the international VLBI network. He is a member of the 2001 class of CQ
    Magazine's Amateur Radio Hall of Fame.

    In 2016, ARRL awarded Clark with its President's Award, to recognize
    his 60 years of advancing amateur radio technology. On that occasion,
    McGwier said, "There would be no AMSAT to inspire all of this work
    without Tom Clark. Tom...saved the organization and inspired all of us
    to look to the future and aim for the stars," McGwier said.

    Clark was a Fellow of the American Geophysical Society and the
    International Association of Geodesy.

    GEORGIA GETS A NEW SECTION MANAGER; RE-ELECTED SMS BEGIN NEW TERMS
    ON OCTOBER 1

    Jim Millsap, K9APD, will become the ARRL Georgia Section Manager (SM)
    on Friday, October 1. Millsap, of Acworth, was the only candidate who
    applied by the June 4 nomination deadline. Millsap has been an ARRL
    Emergency Coordinator and District Emergency Coordinator. He also
    served as the ARRL Southeastern Division Vice Director from 2012 to
    2014. Outgoing SM David Benoist, AG4ZR, of Senoia, decided not to run
    for a new term after serving since November 2016.

    These incumbent SMs faced no challengers in the summer election cycle
    and will also begin new 2-year terms of office on October 1: Robert
    Wareham, N0ESQ (Colorado); Diana Feinberg, AI6DF (Los Angeles), Carol
    Milazzo, KP4MD (Sacramento Valley); Bill Hillendahl, KH6GJV (San
    Francisco); Stuart Wolfe, KF5NIX (South Texas); Monte Simpson, W7FF
    (Western Washington), and Dan Ringer, K8WV (West Virginia).

    Eastern Washington Section Manager Jo Whitney, KA7LJQ, was also the
    only nominee when the June 4 nomination deadline arrived. Whitney, of
    Yakima, was initially scheduled to start her elected term of office on
    October 1. However, she was appointed to start her term of office on
    July 1 after outgoing SM Jack Tiley, AD7FO, stepped down before the
    completion of his term.

    ARISS SEEKS HOSTS FOR HAM RADIO CONTACTS WITH SPACE STATION CREW

    Starting on October 1, Amateur Radio on the International Space Station
    (ARISS <http://www.ariss.org/>) will accept applications from US
    schools, museums, science centers, and community youth organizations (individually or working together) interested in hosting amateur radio
    contacts with crew members on the International Space Station (ISS).
    Contacts will be scheduled between July 1 and December 31, 2022. Crew scheduling and ISS orbits will determine the exact contact dates. ARISS
    is looking for organizations that will draw a sizeable number of
    participants and integrate the contact into a well-developed education
    plan.

    The deadline to submit is November 24. Proposal information <https://ariss-usa.org/hosting-an-ariss-contact-in-the-usa/> and more
    details, including expectations, proposal guidelines, and a proposal
    form are on the ARISS-US website. An ARISS introductory webinar session
    will be held on October 7 at 8 PM ET (2400 UTC). Sign up <https://ariss-proposal-webinar-fall-2021.eventbrite.com/> for the
    webinar via Eventbrite.

    Each year, ARISS provides tens of thousands of students with
    opportunities to learn about space technologies and communications
    through amateur radio. Crew members aboard the ISS will participate in scheduled amateur radio contacts. These contacts are approximately 10
    minutes long and allow students to interact with the astronaut through
    a question-and-answer session.

    The program offers learning opportunities by connecting students to
    orbiting astronauts through a partnership that includes ARRL, AMSAT,
    and NASA, as well as other amateur radio organizations, and space
    agencies in Russia, Canada, Japan, and Europe. The program's goal is to
    inspire students to pursue interests and careers in science,
    technology, engineering, and mathematics (STEM), as well as amateur
    radio.

    "Educators overwhelmingly report that student participation in the
    ARISS program stimulates interest in STEM subjects and in STEM
    careers," ARISS said in their announcement regarding the contact
    opportunities. ARISS says enthusiasm sparked by a school contact may
    also lead to an interest in ham radio among students and to the
    creation of ham radio clubs in schools. Some educators have even become
    radio amateurs after experiencing a contact with an ISS crew member.

    ARISS is celebrating 20 years of continuous amateur radio operations on
    the ISS. Contact <ariss.us.education@gmail.com> ARISS-US for additional information.

    MANY HAM RADIO ORGANIZATIONS REPRESENTED AT 2021 ARRL NEW ENGLAND
    DIVISION CONVENTION

    This year's Northeast HamXposition <https://hamxposition.org/> drew
    about 1,200 attendees to its new location in Marlborough,
    Massachusetts, during September 10 - 12. The event hosted the ARRL New
    England Division <https://nediv.arrl.org/> Convention, and was formerly
    held about 15 miles away in Boxborough, Massachusetts. This was the
    first year the convention was held at this location because the event
    was canceled in 2020 due to the COVID-19 pandemic. Event proceeds go to
    the New England FEMARA <https://accessscholarships.com/scholarship/new-england-femara-scholarship> Scholarship fund, which helps students attend a college or trade school
    of their choice. Scholarships are administered by the ARRL Foundation Scholarship Program <http://www.arrl.org/scholarship-program>.

    HamXposition Chairman Bob DeMattia, K1IW, and his committee said they
    were pleased with the turnout, given last year's cancellation and this
    year's new venue. The event was held at the Best Western Royal Plaza
    Hotel and Trade Center in Marlborough. Although there were some
    last-minute cancellations from a handful of exhibitors and presenters,
    W1 QSL Bureau Co-Manager Eric Williams, KV1J, believed that there was "remarkably good attendance," despite the concerns of COVID-19. The W1
    QSL Bureau team included ARRL Director of Operations Bob Naumann, W5OV,
    who checked DXCC and other ARRL award applications throughout the
    convention.

    In addition to ARRL Vice President Mike Raisbeck, K1TWF, and New
    England Division Director Fred Hopengarten, K1VR, the 2021 ARRL
    convention team included New England Division Vice Director Phil
    Temples, K9HI; Field Services Manager Mike Walters, W8ZY; Senior Member Services Representative Kim McNeill, KM1IPA; Director of Operations Bob Naumann, W5OV, and Public Relations and Innovation Director Bob
    Inderbitzen, NQ1R. Several Section Managers and other Field
    Organization volunteers also supported the convention. Raisbeck and
    Temples also served as the convention's Vice Chair and Program Chair, respectively.

    The Nashua Area Radio Society (NARS <http://www.n1fd.org/>) of New
    Hampshire demonstrated a variety of activities to encourage new
    licensees to become "radio active." NARS was among several radio clubs
    and organizations that staffed visitor booths at the event.

    Members of the Women Radio Operators of New England (WRONE) hosted an
    exhibit for the Young Ladies' Radio League (YLRL <https://ylrl.org/>), represented by District 1 YL Barbara Irby, KC1KGS, and Anne Manna,
    WB1ARU. These organizations encourage and assist women entering the
    Amateur Radio Service.

    Sci-Tech Amateur Radio Society (STARS
    <https://nescitech.org/clubs/stars/>) of New England Sci-Tech in
    Natick, Massachusetts, offered a hands-on exhibit and conducted a youth
    panel. STARS is hosted by the STEM Education Center and Makerspace at
    New England Sci-Tech.

    DXCC and Contest Dinner speaker Adrian Ciuperca, KO8SCA, recapped
    the DXpedition and IARU Contest activities and activations from Market
    Reef and Åland Islands. On Saturday, the banquet speaker was Philip J. Erickson, W1PJE, of Haystack Observatory, operated by Massachusetts
    Institute of Technology (MIT). Erickson discussed HamSCI <http://www.hamsci.org/>'s latest ionospheric science investigations,
    supported in partnership with radio amateurs and scientists from
    Haystack Observatory and other institutions.

    The ARRL leadership team hosted an ARRL Membership Forum on Saturday.
    ARRL Washington Counsel Dave Siddall, K3ZJ, was among the attendees.

    Inderbitzen's keynote address on Saturday morning included a tribute to
    the September 11 attacks and a color guard supported by the local Boy
    Scouts of America. He also attended the youth panel and met with many
    young hams, parents, and their advisors throughout the event, including
    Olin College of Engineering undergraduate Zachary Sherman, KC1NXK, who exhibited for Olin Collegiate Amateur Radio Club, KC1LHR. -- Thanks to

    IN BRIEF...

    The AO-92 and FalconSAT-3 satellites have been shut down. AO-92
    (Fox-1D) had started to change its behavior after a number of weeks of
    being powered on. In particular, the integrated housekeeping unit (IHU) switched to safe mode. This was likely due to low voltage during
    eclipse, which is when it should be drawing very little power if no one
    uses it. Mark Hammond, N8MH, also reported that he was turning off FalconSAT-3's transmitter, due to low voltage. -- Thanks to Burns

    The IARU Region 1 Monitoring System finds Radio France International
    splatter "untenable." The International Amateur Radio Union Region 1
    Monitoring System (IARUMS) August newsletter <https://www.iaru-r1.org/wp-content/uploads/2021/09/IARUMS-Newsletter-2021-08.pdf>

    reports that Radio France International was active daily between 2100
    and 2200 UTC on 7205 kHz. The report says splattering appeared
    "massively" down to 7186 kHz, which IARUMS called "an untenable
    condition." IARUMS said that the "especially well-known intruders"
    included Voice of Broad Masses (VOBM) on 7140 and 7180 kHz from
    Eritrea. "From time to time, China Radio International was heard on
    14,000 kHz (and intermodulation of 13,855 kHz and 13,710 kHz)." The
    usual players among the over-the-horizon radar (OTH-R) systems also
    were active almost daily. Intruding signals heard in IARU Region 1 may
    be causing problems elsewhere in the world.

    Pocket calculator inventor and home computing pioneer Sir Clive
    Sinclair died at his home on September 16 following a long illness. He
    was 81. Sinclair may have been best known for popularizing the home
    computer. Leaving school at 17, he worked for 4 years as a technical
    journalist to fund Sinclair Radionics and created the Sinclair Spectrum
    and the first computer, the Sinclair ZX-81. Many modern-day titans of
    the games industry got their start on one of his ZX models. Back in the
    day, the gamer's computer of choice was either the ZX Spectrum 48K or
    its rival, the Commodore 64. Among his other inventions was a
    coin-sized radio. Despite his computer background, Sinclair declined to
    use the internet, email, or even computers.

    THE K7RA SOLAR UPDATE
