    2023 Hamvention Wrap-Up

    The 2023 Dayton Hamvention is in the books! It was a great weekend in
    Xenia, OH and at the various other events in the surrounding area. The
    AMSAT booth and satellite demo area saw continuous traffic and attendees
    had an excellent time at the informal AMSAT Dinner at Tickets on Thursday evening and the TAPR/AMSAT Banquet on Friday evening.

    The AMSAT forum from Saturday afternoon can be viewed at https://www.youtube.com/watch?vYTVTzJlXk&t680s (the ARISS forum
    precedes the AMSAT forum, so you can back up the live stream to view that)

    The video presented at the AMSAT forum featuring AMSAT engineers can be
    viewed at https://www.youtube.com/watch?vzTtJZPfL8

    Grace Papay, KE8RJU, gave a talk at the Youth Forum on "Amateur Radio Satellites Both Near and Far" and her presentation can be viewed at https://www.youtube.com/watch?v-jsYYHY8w&t

    We hope everyone enjoyed Hamvention this year and hope to see everyone in
    Xenia next May!

    AMSAT Orbital Elements Manager Retires

    It is time for me to retire from the position of AMSAT-NA Orbital Elements Manager.

    I have held this position since October 8, 1993, when I inherited it from
    Dick Campbell, WR5RW (formally N3FKV). I also inherited a BASIC sorting
    program from Dick which has faithfully produced the AMSAT TLE format each
    week for almost 30 years. Today I have to use an emulator, but it
    consistently produces the format we (and our computer tracking programs)
    expect to see.

    But, have no fear, Joe Fitzgerald, KM1P has been developing a
    software-based system that pulls the TLE data directly from the internet (Space-Track, 18SPCS), formats it, and sends it out to the amateur radio community. Joe has been testing it for over a month now and it is ready to
    go!

    It has been a privilege to serve AMSAT as Orbital Elements Manager and I
    will miss the Thursday night routine of sending out the AMSAT TLE. But to
    those who have helped me along the way … thanks. Special thanks to
    Keith
    Pugh (W5IU Silent key), Dick Campbell (WR5RW), Nico Janssen (PA0DLO), and
    also to Joe Fitzgerald (KM1P) for stepping up to the job.

    New SO-50 Distance Record

    A new distance record has been claimed on SO-50. During a SOTA activation
    of Pine Mountain in the Upper Peninsula of Michigan on May 24, 2023 at
    13:16 UTC, Joe Werth, KE9AJ, worked George Mamjis, MI0ILE, in Northern
    Ireland. KE9AJ's location was EN55wu90gp and MI0ILE's location was
    IO64wn80. The distance between the two locations is 5,584 km. The previous record on this satellite was 5,523 km - set by F4DXV and N1AIA on October
    24, 2018.

    Changes to AMSAT-NA TLE Distribution for May 25, 2023

    Two Line Elements or TLEs, often referred to as Keplerian elements or keps
    in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin
    files are updated Thursday evenings around 2300 UTC, or more frequently if
    new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/

    This week there are no additions or deletions to the weekly AMSAT-NA TLE distribution.

    ARISS News

    Amateurs and others around the world may listen in on contacts between
    amateurs operating in schools and allowing students to interact with
    astronauts and cosmonauts aboard the International Space Station. The
    downlink frequency on which to listen is 145.800 MHz worldwide.

    Quick list of scheduled contacts and events:

    Muslyumovo, Tatarstan, Russia, direct via TBD

    The ARISS mentor is RV3DR
    Contact is go for Sat 2023-06-10 10:15 UTC

    The crossband repeater continues to be active. If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume
    up, and talk on the crossband repeater. So give a listen, you just never
    know.

    Comments on making general contacts

    I have been seeing a lot of traffic on Facebook and I suspect on other
    social media sites with people asking why they are not hearing the crew
    make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk.
    Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule
    the school contacts. Hopefully this will help you better schedule your opportunities.

    Typical daily schedule

    Wakeup to Workday start.5 hours
    Workday start to Workday end hours
    Workday end to Sleep hours
    Sleep to wakeup.5 hours

    The crew's usual waking period is 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking
    and before sleeping, when they have personal time. They're usually free
    most of the weekend, as well.

    SSTV events are not that often. So please check out https://www.ariss.org/
    for the latest information or watch for the ARISS announcements.

    And don’t forget that the packet system is active.

    As always, if there is an EVA, a docking, or an undocking; the ARISS radios
    are turned off as part of the safety protocol.

    I will be in EN84, EN85 and EN76 from Friday, May 26 thru Monday, May 29.
    Using an Icom 9700, Arrow antenna and SAT controller. Listening for Europe
    for eastern passes. All QSOs going to LoTW as N8MR.

    Major Roves:
    I post ’em as soon as I know about ’em. Just be aware that
    I still work
    roughly 60 hours a week. Tnx!

    Hamfests, Conventions, Maker Faires, and Other Events

    AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events.

    + AMSAT Space Symposium and Annual General Meeting
    October 20-21, 2013
    Dallas, Texas

    AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events.

    AMSAT Ambassador Clint Bradford, K6LCS, says,

    "Think a 75-minute presentation on "working the easy satellites" would be appropriate for your club or event? Let me know by emailing me at
    k6lcsclint (at) gmail (dot) com or calling me at 909-999-SATS (7287)!"

    Clint has NEVER given the exact same show twice: EACH of the 150+
    presentations so far has been customized/tailored to their audiences. An
    email message received after a recent presentation:

    "I really enjoyed Clint's presentation last night. The fact that he had
    taken the time to research and know something about his audience and
    welcomed interaction made it very informative and enjoyable. This was a refreshing change from many canned YouTube presentations I've tried to
    watch, which were poorly done, fuzzy video or muddy audio, or a badly
    prepared presenter stumbling his way through, with any valuable info lost
    along the way. Thanks for hooking this one up."

    Satellite Shorts From All Over

    + John Shoffner, KO4MJC, pilot of the Axios Space AX-2 mission, was
    reported to have made casual QSOs from the ISS via the ISS repeater on May
    25, 2023. (Thanks to ARISS for this information)

    + The Tevel-3 and Tevel-6 satellites will be active through May 29, 2023 at 18:35 UTC.
    Downlink frequency 36.400 MHz, Uplink frequency 45.970MHz NO PL t
    one.
    (Thanks David Greenberg, 4X1DG, for this information)

    + Four CubeSats developed by the Korea Astronomy and Space Science
    Institute (KASI) were launched on a Korean NURI rocket this past week.
    These CubeSats were not IARU coordinated and the downlink of one of the satellites is on 437.800 MHz. This has the potential to cause QRM to the
    ISS FM repeater. (Thanks PE0SAT for the above information)

    + URESAT Antonio de Nebrija is expected to launch on the SpaceX
    Transporter-8 mission on June 8th. Details available at https://www-ure-es.translate.goog/uresat-antonio-de-nebrija-sera-lanzado-el -8-de-junio/?_x_tr_slto&_x_tr_tl&_x_tr_hl-GB
