    Interesting ARRL Ham Radio Open House Locations

    ARRL Ham Radio Open Houses [ http://www.arrl.org/world-amateur-radio-day?utm_source=Informz&utm_medium=Email&utm_campaign=ARRL
    ] are happening all over the western hemisphere, and more dates are being
    added each week. Throughout the entire month of April, radio clubs, schools, and even museums are opening their doors to help introduce the public to amateur radio. They will show of their ham radio stations, demonstrating the technology and innovation enjoyed by radio amateurs today.


    [http://www.arrl.org/world-amateur-radio-day]


    Some of the open houses will take place on April 18, World Amateur Radio Day, which this year marks 100 years since the International Amateur Radio Union
    was founded in Paris, France.


    There are some interesting sites hosting ARRL Ham Radio Open House events.
    The Vintage Radio and Communications Museum [ https://www.vrcmct.org/ ] , W1VCM, in Windsor, Connecticut, will welcome guests to theirs on April 18.
    The museum is host to exhibits that show off the developments in
    communications through the decades, from the 1800s to the late 20th century. Many of the volunteers at the museum are active hams and are able to relay
    how foundational evolution of gear and technology was for the modern,
    digital, amateur radio landscape.


    New England Sci-Tech in Natick, Massachusetts, W1STR, is also hosting an open house [ https://nescitech.org/content.aspx?page_id=22&club_id=508616&module_id=611760
    ] on April 18. This maker space workshop and science center engages young people with outreach programs and gets members of the public hands-on with
    many science, technology, engineering, and mathematics (STEM) projects. They have an active amateur radio club among all the excitement.


    On the other end of North America, the Arctic Amateur Radio Experimenters, KL7EX, will be hosting an Open House in Fairbanks, Alaska.

    ARRL Iowa Section Wins Ham Exemption From Handsfree Law

    ARRL volunteers in the Iowa Section have cause to celebrate. Their
    state-level advocacy work on behalf of amateur radio has resulted in an exemption to the state's handsfree law that covers ham operators.


    Iowa Senate File 22 (SF22), a bill addressing distracted driving, had been in development since 2020. Former ARRL Section Manager Lelia Garner, WA0UIG, and Iowa Section State Government Liaison Alan Erickson, WB0OAV, played a crucial role in fostering and maintaining key legislative relationships. Over the course of five years, they navigated the legislative process to ensure the continued exemption for amateur radio operators.


    The COVID-19 pandemic and political opposition to the measure ground the bill to a halt, but the ARRL Iowa Section volunteers continued to engage in the process and ensure that amateur radio was represented as the legislature finally took the bill back up. The final language of the bill included, "The provisions of this subsection do not apply to ... A person using a two-way radio transmitter or receiver who is licensed with the federal communications commission in amateur radio service."


    Being proactive about sharing the good work amateur radio operators do was
    key. "We presented a carefully crafted exemption proposal, backed by evidence of our contributions as a radio service," said Garner.


    The texting bill (SF22) passed the Iowa Senate with a vote of 47-1 on March
    18, 2025, and the Iowa House passed it on March 26, 2025 with a vote 54-11.
    On April 2, 2025, it was signed by Governor Kim Reynolds and goes into effect July 1, 2025.


    The process encouraged Erickson. "Every legislator I spoke with appreciated
    the public service that licensed amateur radio provides. They also
    acknowledged the responsibility demonstrated by amateur radio operators. I
    was impressed by their willingness to exempt amateur radio from their texting bill, and was also humbled that we have a duty to preserve this awesome reputation."

    Effort to Save Marconi Towers in Canada - Public Invited to Vote on Project

    There's an effort underway to save some of Marconi's original towers, and an online poll is open for people to vote [ https://nextgreatsave.nationaltrustcanada.ca/2025/entry/85 ] on it being a restoration project through the "Next Great Save" project from the National Trust for Canada.


    Some of Marconi's first messages were received and transmitted using the
    Battle Harbour Marconi Towers, thought to be the last of their kind standing
    in North America. News of Admiral Robert Peary's 1909 North Pole expedition
    was transmitted by these towers. After 100 years, the twin towers are in need of repair.


    [https://nextgreatsave.nationaltrustcanada.ca/2025/entry/85]

    Broadcast audio processing company Orban Labs has donated an Optimod 9100B AM processor signed by company founder Bob Orban to ARRL in support of this
    year's annual auction. The donation was made at the annual National
    Association of Broadcasters convention. Orban Labs has set the standard for audio processing in the broadcast industry for 50 years. Its donation will be used to raise funds in support of ARRL's programs in amateur radio at the annual auction. Company founder Bob Orban was on hand to sign the cover plate which makes this unique, vintage, and fully functional item a valuable collector's piece. Orban Labs co-owner Mike Pappas, W9CN, organized this generous donation which was accepted on behalf of ARRL by Pacific Division Director Anthony Marcin, W7XM.


    Tad Cook, K7RA, has received the ARRL President's Award. ARRL Northwestern Division Director Mark Tharp, KB7HDX, presented the award to Cook on March 8, 2025, for 36 years of service to ARRL writing the weekly W1AW Propagation Forecast Bulletin. Cook also wrote The K7RA Solar Update for the ARRL Letter. He retired in January 2025, citing a recent ALS diagnosis preventing him from continuing. "He is genuinely a good person," said Tharp, who noted the award was a complete surprise to Cook. One of the happiest moments of Cook's many years as a radio amateur was getting on the air when he was 11 years old and making his first QSO on a Heathkit DX-20 with a non-working VFO. His was inspired to become a ham by a pair of Boy Scout brothers working on their
    Morse code badge, and from watching them get on the air, making a QSO to Oregon, several hundred miles away.


    ARRL Letter Editor John Ross, KD8IDJ, worked with Cook for four years. "Early every Friday morning, we would work together to make sure his report for the ARRL Letter was on time and the way he wanted it to read," said Ross. "Sometimes I think Tad knows more about the Sun than the Sun!" Watch for the full story in an upcoming issue of QST magazine.

    The ARRL Solar Report

    ARRL Solar Update April 10, 2025

    A relatively fast-moving stream of solar wind has been buffeting Earth's magnetic field, and this is causing minor G1-class geomagnetic storms. High-latitude sky watchers should be alert for auroras. Solar activity
    reached moderate levels with several flares.


    Radio blackouts reaching the R1 levels were observed over the past 24 hours with the largest on April 8. There is a chance for R1-2 (Minor-Moderate), and radio blackouts will persist through April 11 primarily due to the flare potential. An associated coronal mass ejection (CME) was observed on April 6. Modeling of the event showed the potential for a grazing blow around midday
    on April 11. There have been no Earth-directed CMEs in coronagraph imagery.


    The 10.7 centimeter flux: April 11, 145; April 12 - 14, 140; April 15, 135;
    and April 16 - 27, 140.


    Predicted Sunspot numbers: April 11, 159; April 12, 158; April 13, 164; April 14, 169
