ARRL Wants Every Ham to Help Us Pass The Bill

[http://www.arrl.org/HOA]


ARRL needs every radio amateur in the United States to send letters to Washington as we continue our nationwide grassroots campaign to pass the Amateur Radio Emergency Preparedness Act (H.R. 1094 / S. 459) to secure
antenna rights. The process is simple: click the button at www.arrl.org/HOA [ http://www.arrl.org/HOA?utm_source=Informz&utm_medium=Email&utm_campaign=ARRL
] , put in your call sign, and press the red SEND MY LETTERS button. It takes mere seconds!


The letters will automatically be sent to your elected officials encouraging them to support the bipartisan bills. This legislation is intended to prevent restrictive homeowners' association (HOA) rules that currently prohibit or severely limit the installation of amateur radio antennas. Passage would give amateur radio operators the same rights to install antennas on their property as those enjoyed by users of TV antennas, wireless internet, and flagpoles.


Spreading the Word

ARRL CEO David Minster, NA2AA, was the guest on the Ham Radio Crash Course YouTube channel [ https://www.youtube.com/live/xMLDannix2M ] . Host Josh
Nass, KI6NAZ, talked with Minster for 45 minutes about this important letter writing campaign.


ARRL West Gulf Division Director John Robert Stratton, N5AUS, shared insight into the importance of getting every ham to send a letter on the W5KUB
Amateur Radio Roundtable podcast with Brett Glass, WY7BG, and Glen Popiel, KW5GP. See that discussion on YouTube [ https://youtu.be/Ot2IGxRn87Q?t=376 ]
, listen to it on Podbean [ https://www.podbean.com/ew/pb-g9tvg-1973e51 ] ,
or view it on Facebook [ https://www.facebook.com/tom.medlin.9/videos/783489077637321?idorvanity=279273778772594
] .


"You don't have a be a member," said Stratton. "Any amateur radio operator in or out of an HOA should go to the website." Go to www.arrl.org/HOA [ http://www.arrl.org/HOA?utm_source=Informz&utm_medium=Email&utm_campaign=ARRL
] .


ARRL is also encouraging radio clubs to provide letters of support, and is urging each club officer to sign the letters. There are instructions for
clubs on how to complete the letter [ https://arrl.org/files/file/Clubs/Completing the Club Letters for
Congress.pdf ] [PDF] and a sample letter that each club can customize with their information [ https://arrl.org/files/file/Clubs/Universal Club Letter
For ARRL Legislation.docx ] [DOCX].

Hams Needed to Track NASA Moon Mission

The National Aeronautics and Space Administration (NASA) is seeking
volunteers to passively track the 2026 Artemis II Orion spacecraft as the crewed mission travels to the Moon and back to Earth [ https://www.nasa.gov/mission/artemis-ii/ ] .


The Artemis II test flight will send NASA astronauts Reid Wiseman, KF5LKT; Victor Glover, KI5BKC; and Christina Koch, along with Canadian Space Agency (CSA) astronaut Jeremy Hansen, KF5LKU, on an approximately 10-day mission around the Moon.


Targeted for no later than April 2026, the mission will rely on NASA's Near Space Network and Deep Space Network for primary communications and tracking support throughout its launch, orbit, and reentry. However, with a growing focus on commercialization, NASA wants to further understand industry's tracking capabilities.


This collaboration opportunity builds upon a previous request released by NASA's Space Communication and Navigation Program (SCaN ) during the Artemis
I mission in 2022. Ten volunteers successfully tracked the uncrewed Orion spacecraft on its journey thousands of miles beyond the Moon and back.


One of those volunteers tracking in 2022 was Scott Chapman, K4KDR, of Montpelier, Virginia. "Sometimes it's what you don't know that makes this
kind activity interesting," said Chapman. "All I had was a small S-band dish and receiver and wasn't sure what I could or couldn't hear...but when I
started hearing the signals...it made everything worth it."


Chapman said he felt good about the whole process and, while it was interesting, it was also lot of fun!


There were also other participants during the Artemis I mission, including international space agencies, academic institutions, commercial companies, nonprofits, and private citizens who were also attempting to receive Orion's signals. Chapman added that NASA is also looking for commercial partnerships
to share in the process.


If you're interested in volunteering for next year's event, all of the information can be found at SAM.gov [ https://sam.gov/workspace/contract/opp/50d4e81f54e34118a8164fb786b554a6/view
] . The response deadline is October 27, 2025, at 5:00 PM EDT.

National Preparedness Month: Use Your Ham Radio for Public Service

[https://www.arrl.org/ares]


Amateur radio has long been a vital partner with served agencies in providing communications support, passing traffic, and performing other tasks, both in times of crisis and in times of community service. Through community events, hams help out before and When All Else Fails(R).


The best way to become a part of serving the greater good in your area is by joining your local ARRL Amateur Radio Emergency Service(R) (ARES(R)) group. "Every disaster starts and ends at the local level, and so should community resilience through radio," said ARRL Director of Emergency Management Josh Johnston, KE5MHV. "Local ARES groups are set up based on the needs of the
local community and local volunteers are critical to making sure they are
able to serve when needed."


ARRL has a tool to help hams get plugged in with a group near them. An interactive map at www.arrl.org/find-an-ares-group [ http://www.arrl.org/find-an-ares-group?utm_source=Informz&utm_medium=Email&utm_campaign=ARRL
] (example below) will let those interested in serving connect with local leadership. This flyer [ https://www.arrl.org/files/file/Public Service/ARES/ARES Flyer 2024.pdf ] [PDF] talks about what ARES does at the local level.


[http://www.arrl.org/find-an-ares-group]


As September ends, the lessons from National Preparedness Month shouldn't
stop with the change of the calendar. As ARRL Sections prepare for the Simulated Emergency Test (SET) in October, being a trained member of a local ARES group will add to your personal, family, and community resilience.

NCVEC Question Pool Committee Removes Extra-Class Question E6D07 From Use

[https://www.arrl.org/volunteer-examiners]


The National Conference of Volunteer Examiner Coordinators (NCVEC [ https://www.ncvec.org/ ] ) Question Pool Committee (QPC [ https://www.ncvec.org/index.php/question-pool-committee ] ) has announced the immediate removal of Extra-Class question E6D07 from the Element 4
Extra-Class question pool and from use on examinations. The decision was made after it was determined that the question contained more than one correct answer.


The current Element 4 Extra-Class pool, effective July 1, 2024, remains valid through June 30, 2028. All Volunteer Examiner Coordinators (VECs) and
examiners are instructed to remove E6D07 from examinations as soon as
possible.


Updated files reflecting this change are now available for download at the NCVEC website: www.ncvec.org/index.php/2024-2028-extra-class-question-pool-release [ https://www.ncvec.org/index.php/2024-2028-extra-class-question-pool-release ]
.


The ARRL VEC [ https://arrl.org/volunteer-examiners ] advises the community
to regularly check the NCVEC website for updates to the question pools, which may include errata and withdrawn questions.

The ARRL Solar Report

ARRL Solar Report September 25, 2025

Solar activity reached moderate levels this past week. An impulsive M1.0
flare was observed on September 24 from Region 4217. Slight growth was
observed in Region 4226 with an increase in spots near the leader. New
Regions 4229 and 4230 were numbered this period. All other regions were
either stable or in decay. No Earth-directed CMEs were observed. Solar
activity is expected return to low activity, with a chance for isolated
M-class flare activity (R1-R2/minor-moderate) through September 25.


Solar wind parameters were indicative of the arrival of a negative polarity coronal hole high speed stream (CH HSS). Solar wind speed increased from approximately 310 km/s to near 530 km/s. Total field showed an increase beginning on September 22. The CH HSS influence persisted through September
23 and will slowly diminish to background levels on September 25. A trend towards nominal solar wind conditions is expected through September 26 as
Earth moves out of a geoeffective position with the CH HSS.


The 10.7-centimeter flux: September 25, 185; September 26 - 27, 175;
September 28 - 30, 170; October 1, 160.


Predicted sunspots: September 25, 131; September 26, 125; September 27, 137; September 28, 121; September 28, 144; September 29, 116; September 30, 149; October 1, 131.
