*ARRL Launches Nationwide Grassroots Campaign to Pass Amateur Radio 
Emergency Preparedness Act*

ARRL has launched a nationwide grassroots campaign aimed at securing the 
passage of federal legislation that would grant Amateur Radio Operators 
the same rights to install antennas on their property as those enjoyed 
by users of TV antennas, wireless internet, and flagpoles.

The campaign, announced in an ARRL Member Bulletin 
<https://arrl.informz.net/z/cjUucD9taT0zNDM5NzM0JnA9MSZ1PTUyNTQ3MzY2NCZsaT0zOTc0NDkyNg/index.html> 
on September 17, 2025, follows the reintroduction of the Amateur Radio 
Emergency Preparedness Act in February 2025 (see ARRL News 02/07/2025 
<https://arrl.informz.net/z/cjUucD9taT0zNDM5NzM0JnA9MSZ1PTUyNTQ3MzY2NCZsaT0zOTc0NDkyNw/index.html>). 
The bipartisan bills -- H.R.1094 
<https://arrl.informz.net/z/cjUucD9taT0zNDM5NzM0JnA9MSZ1PTUyNTQ3MzY2NCZsaT0zOTc0NDkyOA/index.html> 
in the House and S.459 
<https://arrl.informz.net/z/cjUucD9taT0zNDM5NzM0JnA9MSZ1PTUyNTQ3MzY2NCZsaT0zOTc0NDkyOQ/index.html> 
in the Senate -- are designed to prevent restrictive homeowners’ 
association (HOA) rules that currently prohibit or severely limit the 
installation of amateur radio antennas, even when such antennas are 
hidden in trees, placed in attics, mounted on vehicles, or look like 
flagpoles.

*“This legislation is about restoring equal rights to licensed Amateur 
Radio operators,”* said ARRL President Rick Roderick. *“These 
restrictions hinder not only the enjoyment of Amateur Radio, but also 
its vital role in emergency communication during disasters.”*

*/Public Support Needed for Passage/*

To advance the legislation, ARRL is calling on its members and all 
licensees of the US Amateur Radio Service to take action by sending 
letters to their congressional representatives. Through a dedicated 
online tool at *https://www.arrl.org/HOA 
<https://arrl.informz.net/z/cjUucD9taT0zNDM5NzM0JnA9MSZ1PTUyNTQ3MzY2NCZsaT0zOTc0NDkzMA/index.html>*, 
hams can easily generate and submit pre-drafted letters with a few clicks.

*Go to — https://www.arrl.org/HOA 
<https://arrl.informz.net/z/cjUucD9taT0zNDM5NzM0JnA9MSZ1PTUyNTQ3MzY2NCZsaT0zOTc0NDkzMA/index.html>*

*— and help us by sending your letters to your Representative and Senators.*

ARRL has emphasized that every letter matters. “Your Representative and 
Senators need to know that the passage of this legislation is important 
to you.”

bill, please visit www.arrl.org/current-legislation

*National Preparedness Month: Know Your Risk*

Radio amateurs are valuable resources to their communities in times of 
crisis. This week, hams in Connecticut were featured in news coverage 
<https://arrl.informz.net/z/cjUucD9taT0zNDM5NzM0JnA9MSZ1PTUyNTQ3MzY2NCZsaT0zOTc0NDkzNw/index.html> 
as they participated in a mass casualty drill with St. Vincent Medical 
Center in Bridgeport. Several scenarios played out in which amateur 
radio volunteers helped the hospital connect with other medical 
facilities, including a targeted cyberattack, mass shooting, and 
explosions.

While radio can provide resilience to communities, preparedness for 
those who would operate the radios begins at home. During National 
Preparedness Month, ARRL is sharing resources from the Federal Emergency 
Management Agency (FEMA) on how to be prepared.

The starting point for building your own resilience is to understand 
what threats you face in your area. On the website *www.Ready.gov 
<https://arrl.informz.net/z/cjUucD9taT0zNDM5NzM0JnA9MSZ1PTUyNTQ3MzY2NCZsaT0zOTc0NDkzOA/index.html>*, 
there are tools to learn what disasters are most likely to impact your 
specific area and how to prepare for them.

ARRL Director of Emergency Management Josh Johnston, KE5MHV, says a plan 
should be tailored to threats you’re likely to face. “While we should 
all be ready for anything – there are going to be threats specific to a 
region. Everyone should be well aware of the events that happen in your 
area,” he said.

There is additional information on the FEMA website to learn about 
region-specific disasters such as hurricanes. Radio amateurs are 
encouraged to find an ARES group in their area at *www.arrl.org/ares 
<https://arrl.informz.net/z/cjUucD9taT0zNDM5NzM0JnA9MSZ1PTUyNTQ3MzY2NCZsaT0zOTc0NDkzOQ/index.html>*.

*Gear Packed for 3YØK DXpedition to Bouvet in February 2026*

The 3YØK DXpedition to Bouvet Island has packed its shipping container 
of gear. The team spent the weekend near Oslo, Norway, getting things 
ready, including generators, tents, tools, and — most importantly — 
radios, antennas, and amplifiers. This checks off another large box on 
the to-do list before they depart in February of next year.

This international team of radio amateurs is aiming to activate the #10 
most-wanted DX entity, Bouvet Island, in February 2026. With 24 
operators, two camps, and a load of gear, they hope to provide a lot of 
QSOs to those who need the entity for their DXCC totals. Bouvet is in 
the South Atlantic Ocean, 1600 miles from Cape Town, South Africa, and 
1000 miles north of continental Antarctica.

ARRL Education and Learning Support Specialist Max Freedman, N4ML, is 
part of the team. At 21 years of age, he will be the youngest person to 
ever set foot on the island, and is the youngest operator known in a 
top-10 DXpedition. He is excited for the opportunity. "I have learned a 
lot being a part of the 3YØK team,” said Freedman. “A lot of work goes 
into a DXpedition, more than most people think. It is an honor to work 
with these high performing ham radio operators to get everything 
prepared for February."

You can find out more about the DXpedition at *3y0k.com

*Section Manager Workshop Held at ARRL Headquarters*

fundraising event. In 2024, 54 stations were on the air across the 
globe. In England, the Halifax & District Amateur Radio Society again 
this year activated the Methodist Church in the Moorland village of 
Blackshaw Head, West Yorkshire. The grand total for the day was 122 
contacts on HF, with around 16 of those being CHOTA to CHOTA contacts.

*ARRL Solar Report September 18, 2025*

Solar activity was at low levels this past week. Low-level C-class 
flaring was observed from Regions 4216 and 4217, as well as from Region 
4213 just beyond the SW limb. Slight growth was observed in all spotted 
regions. No Earth-directed CMEs were observed. Solar activity is 
expected to be low, with a chance for an isolated M-flare 
(R1-R2/minor-moderate), through September 20.

Solar wind parameters were indicative of coronal hole high speed stream 
(CH HSS) influences. Solar wind speed increased to near 760 km/s early 
on 15 Sep before subsiding to between 600-700 km/s. Total field 
decreased from 14 to 5 nT but the Phi angle was negative. Solar wind 
parameters are expected to continue under the influence of a negative 
polarity CH HSS. Solar wind speed is likely to gradually diminish on 
September 20.

The 10.7-centimeter solar flux: September 18, 130; September 19 – 22, 
135; September 23, 130; September 24, 125; September 25, 130.

Predicted sunspot numbers: September 18, 138; September 19, 131; 
September 20, 143; September 21, 128; September 22, 149; September 23,
