Five Steps to Get Ready for April's Ham Radio Open House

We're only days away from April and ARRL's month-long Ham Radio Open House (HROH) [ https://www.arrl.org/world-amateur-radio-day?utm_source=Informz&utm_medium=Email&utm_campaign=ARRL
] . Radio clubs, schools, and other groups that operate a shared ham radio station are urged to join the nationwide event to raise the visibility of amateur radio and related technology. April is also Science Citizen Month,
and April 18 is World Amateur Radio Day. It's also the 100th anniversary of
the International Amateur Radio Union (IARU), making the month a perfect backdrop for engaging the public in an introduction to ham radio.


[http://www.arrl.org/Open-House]


You know the experience when a newcomer visits your amateur radio station:
they have a bit of overwhelmed amazement, taken back by all the new sights
and sounds. You explain to them what each component does, but oftentimes they're gripped in a wide-eyed wonder about all the exciting technology in front of them; the gear, displays filled with radio signal waterfalls and
other graphical interfaces, and the variety of sounds, from Morse code and digital to the voices of faraway people. Look out the window, and eyes are gazed on antennas of all shapes and sizes. In the best of situations, that sensory overload turns into getting on the air, turns into a new member of
this hobby-of-hobbies, turns into a new radio amateur! That's the energy we
are tapping into for ARRL Ham Radio Open House.


Show off all the cool things that can be done in amateur radio Γ-" leading
with our technological innovations, how radio works, and what we can do with our signals. Follow up with getting the visitor hands-on Γ-" let them participate in several of the 1 million acts of science that SciStarter [ https://scistarter.org/citizensciencemonth ] is working to document as part
of April being Citizen Science Month. Get the visitor on the air! Make them feel a part of it, from the moment they walk in.


ARRL wants your club to be successful. Here are the steps to prepare for your club's ARRL Ham Radio Open House:


1. Pick a date
Select a date (or dates) any time in the month of April to host your club station's open house to maximize visitor traffic to your operation.


2. Use the media kit
ARRL has created a comprehensive media kit [ https://www.arrl.org/files/file/Media%20&%20PR/World%20Amateur%20Radio%20Day/2025%20ARRL%20HROH%20Publicity%20Kit.pdf
] prepared by veteran PR professionals on the ARRL Public Relations
Committee. These pros want to help you shine and have given you a turn-key solution. Use as much or as little of it as you'd like - but its all there: Sample press release, PR tip sheet, media outreach timeline, and more. Find
it on www.arrl.org/world-amateur-radio-day [ http://www.arrl.org/world-amateur-radio-day?utm_source=Informz&utm_medium=Email&utm_campaign=ARRL
] .


3. Location, Location, Location!
The ARRL Ham Radio Open House locator tool is available at www.arrl.org/Open-House [ http://www.arrl.org/Open-House?utm_source=Informz&utm_medium=Email&utm_campaign=ARRL
] . It is a two-way street. Add your club's information to the interactive
tool or use it to find an activation already planned in your area. This is
the same tool many are accustomed to using to find ARRL Field Day sites.


4. Be a social media superstar
Social media is how many people find activities. Make sure your club is using the power of this outreach tool to spread the word of your event. In the HROH media kit, you'll find a section devoted to social media best practices.


5. Be ready for next steps
You've planned for weeks, visitors are showing up in droves, they're having a great time getting on the air. Don't leave them hanging on what's next! Have
a plan to get back in touch with them and welcome them to your next club meeting. Prepare a licensing class to enable them to dive right into becoming
a ham. Let them know about your club's ARRL Field Day plans and have them be
a part of them.


The majority of active hams are ARRL members, so let them know the value you get from an ARRL membership and encourage them to join. Don't forget about
the free student membership for those aged 21 and under. www.arrl.org/membership [ http://www.arrl.org/membership?utm_source=Informz&utm_medium=Email&utm_campaign=ARRL

ARRL thanks HamSCI [ https://hamsci.org/ ] -- Ham Radio Science Citizen Investigation -- and SciStarter [ https://scistarter.org/ham-radio-open-house
] for help preparing and promoting this event.

then-sixth-grader Cameron Frey, KD9VGV, talked about his success as a Parks
on the Air(R) operator. "I've done more than 100 activations, and more than
40 different parks. I've also hunted more than 700 different parks," he said.


The ARRL Youth Rally is always a day full of smiles, fun, and empowerment Γ-" make sure your young ham joins us in Dayton!

Caribe Wave 2025 Tsunami Exercise in Puerto Rico

By: Angel Santana, WP3GW

Amateur radio operators in Puerto Rico participated in the Caribe Wave 2025 Tsunami exercise on March 20.


[http://www.tsunamizone.org]


The event is an annual tsunami exercise, designed to validate and advance tsunami preparedness efforts in the Caribbean and adjacent regions. The National Oceanic and Atmospheric Administration (NOAA) and the United Nations Educational, Scientific and Cultural Organization (UNESCO) International Tsunami Information Center (CTIC) served as exercise coordinators.


In Puerto Rico, the exercise was coordinated by the Puerto Rico Seismic
Network [ http://www.prsn.uprm.edu/English/ ] (PRSN) in conjunction with NOAA and the Puerto Rico Emergency Management Bureau (PREMB). Prior to the event,
a meeting was held between PRSN representatives, ARRL Section Emergency Coordinator Emmanuel Cruz, NP4D, and regional emergency coordinators to delineate a plan to disseminate all messages directly by PRSN personnel to
the local amateur radio packet BBS systems and then retransmit them via voice on all radio services including GMRS, FRS, MURS, CB, and amateur radio.


The scenario chosen for Caribe Wave 2025 was a tsunami generated by a
magnitude 8.5 earthquake located approximately 168 miles off the coast of Portugal, with the expected tsunami wave arriving 8 hours later. The exercise started at 11 AM EST with an alert on radio and TV stations made by the Emergency Alert System (EAS). Some cellphone companies also sent the tsunami alert, and all systems stated very clearly that it was a test.


As the PRSN began to receive the tsunami alert bulletins, sent thru the
KP4NTS and KP4DOG packet nodes, the information was sent to different coordinated amateur radio frequencies for emergency events on VHF, 40 meters and 5403.5 MHz island-wide. ARRL Puerto Rico Section Manager Carmen Greene, KP4QVQ, was stationed at the Zone 5 PREMB office in Mayag├║ez to follow how
the bulletins were sent thru various amateur radio outlets. The exercise for the amateur radio part concluded at 1 PM.


Siren systems were also tested, evacuation drills were practiced in coastal cities, and some amateur radio groups formed special nets to gather
information on how they received the advisory alert. For more information on the Caribe Wave exercises, visit www.tsunamizone.org [ http://www.tsunamizone.org ] .

The ARRL Solar Report

K7RA Solar Update - NASA SDO/HMI
[https://sdo.gsfc.nasa.gov/]


ARRL Solar Report March 27, 2025

Solar activity reached moderate levels due to a large flare on March 26.

A Type II radio emission was also observed on March 26. This is likely associated with a coronal mass ejection (CME) that is believed to be from beyond the southwest limb but, due to its location, is not considered to have an Earth-directed component. No additional Earth-directed CMEs were observed.


The arrival of the coronal hole (CH) high speed stream (HSS) is expected to bring an influx of electrons to geostationary orbit through March 29. Strong solar winds, currently near 600 km/s, will compress the Van Allen belts,
which will decrease the number of electrons observed by the NOAA GOES satellite. As winds ease, the flux will rebound towards or above the 1000
solar proton flux unit (pfu) threshold.


The 10.7-cm Radio Flux for March 27 through March 29 is 160, and 165 for
March 30 - 31.


Radio blackouts reaching R1 levels were observed over the past 24 hours. The largest was on March 26 at 0809 UTC.


The predicted sunspot number for the remainder of March is 132 with a high of 139 and a low of 132.


On Saturday, March 29, a deep partial solar eclipse [ https://www.livescience.com/space/the-sun/march-29-solar-eclipse-where-and-when-to-see-the-rare-sunrise-solar-eclipse-from-north-america
] , the first of the year, will be visible across much of the northeastern
U.S. and eastern Canada, as well as in northwestern Europe, northwestern
Africa and northern Russia, as the moon takes a "bite" out of the sun from
our perspective on Earth. Thirteen states will have views of the sunrise
solar eclipse [ https://www.livescience.com/space/the-sun/which-states-will-see-the-march-29-solar-eclipse-and-which-will-see-a-double-sunrise
] , officially beginning at 4:50 AM EDT and ending just under four hours
later, at 8:43 AM EDT. Solar eclipse glasses are recommended to view the
event.
