Amateur Radio Importance Highlighted at National Hurricane Conference

The National Hurricane Conference was held March 25 - 28, 2024, in Orlando, Florida. Amateur radio was well represented at the event. A series of workshops were held that focused on amateur radio's involvement in hurricane tracking, coverage, and recovery.

Among the presenters was the Assistant Amateur Radio Coordinator of WX4NHC at the National Hurricane Center (NHC) Julio Ripoll, WD4R.

Ripoll gave a history of amateur radio's involvement in NHC, including the use of tube radios in the 1980s and the Yaesu FTDX-1200 used today. WX4NHC is also equipped with VHF/UHF radios to access the Florida Statewide Amateur Radio Network (SARnet), as well as digital equipment to communicate with the VoIP Hurricane Net, IRLP, and Winlink to receive emails via amateur radio.

"We were the only means of communication between the National Hurricane Center and the National Weather Service Field Office in Slidell, Louisiana, during Hurricane Katrina," Ripoll said. He went on to highlight other instances of reports given by ham radio that provided mission-critical information that had a major impact on the way NHC handled a storm.

ARRL Director of Emergency Management Josh Johnston, KE5MHV, gave a presentation to the crowd of hurricane experts, meteorologists, and emergency managers about the Amateur Radio Emergency Service® (ARES®).

He spoke of ARRL's role on the board of SAFECOM, a program managed by the Cybersecurity and Infrastructure Security Agency (CISA) that sets the standards of interoperability procedures. Being a part of the group solidifies the Amateur Radio Service as a robust resource before and during times of crisis.

Johnston shared that in 2023, ARES volunteers contributed at least $21.8 million in volunteer hours to their local communities. "Is amateur radio still relevant? Absolutely! Are we still involved in the places that are doing things the right way? Amateur radio absolutely is," he said.

Johnston highlighted the relationship between ARRL and the Federal Emergency Management Agency (FEMA), as well as ARRL's position as a net control station within the SHAred RESources High Frequency Radio Program (SHARES) managed by CISA.

Among other presenters was ARRL's The ARES Letter Editor Rick Palm, K1CE.

He shared a harrowing tale of his family riding out a direct hit from Hurricane Idalia in August 2023. The damage and impact he felt gave him a new perspective on emergency communications, as he went from a volunteer communicator to a storm victim. Read more about his experience in the "Public Service" column in the January 2024 issue of QST.

World Amateur Radio Day is April 18, 2024

World Amateur Radio Day (WARD) is celebrated each year on April 18.

The theme for 2024 is, "A Century of Connections: Celebrating 100 Years of Amateur Radio Innovation, Community, and Advocacy." The global event covers all of the International Amateur Radio Union (IARU) regions and spans 2 days: Thursday, April 18, 2024, 0000 UTC to Friday, April 19, 2024, 0000 UTC.

On April 18, 1925, the IARU was formed in Paris and will celebrate its centenary in 2025. American Radio Relay League (ARRL) Co-Founder Hiram Percy Maxim was the organization's first president.

All radio amateurs are invited to take to the airwaves to enjoy the global friendship with other amateurs and to show their skills and capabilities to the public. WARD is not a contest but rather an opportunity to talk about the value of amateur radio to the public and fellow amateur colleagues. It is also a great opportunity to talk about local radio clubs and amateur radio in local media as a lead-up to ARRL Field Day, which is held each year during the fourth full weekend in June. You can also promote your personal WARD activities on social media platforms like X and Facebook by using the hashtag #WorldAmateurRadioDay.

Reminder: Solar Eclipse April 8

Amateur radio will play many roles in the upcoming solar eclipse that will cross much of North America. Radio amateurs are welcome to participate in ionospheric research that is being conducted. Find information about the Solar Eclipse QSO Party on the HamSCI web site.

Many emergency communications groups, including those affiliated with the Amateur Radio Emergency Service® (ARES®) in the areas near totality are planning to be active surrounding the event. Hams will provide communications to served agencies, such as local governments, relief oranizations, and other groups that could benefit from resilient communications during a time when millions are expected to travel.

New Training Course Offered by the ARRL Puerto Rico Section

The ARRL Puerto Rico Section has a new online training course for prospective amateur radio operators. Fifty-three students have enrolled in the course, taught by ARRL Technical Coordinator and Instructor Carlos Roig, WP4AOH, who draws from the ARRL License Manual and the National Conference of Volunteer Examiner Coordinators pool of questions for the Spanish Zoom course. The course is open to anyone who is interested in becoming an amateur radio operator. In advance of the course, on March 16, 2024, Assistant Section Manager (ASM) Leyda Rios, WP4RBK, offered a Technician training demonstration to 10 registered students at the University of Puerto Rico, Mayaguez Campus.

The session was an overview of amateur radio and its various activities. Students were most interested in the band plan, the phonetic alphabet, and how to communicate with others. The instruction session also included an introduction to amateur radio equipment and antennas, including how to operate and set up the equipment. There was also a demonstration of a VHF/UHF radio to establish a simple repeater contact. "The range of amateur communication and the capabilities astounded the students," Rios said.

Several students were also interested in learning more about how to utilize the radio equipment and how to establish their first contact, while others have an interest in emergency communications for this year's hurricane season.

For additional information about the training course, contact Leyda Rios, WP4RBK, at [email protected].

Contribute to Science While You Operate

The Solar Eclipse QSO Party (or SEQP) is an on-air event coming up on April 8, the same day as the next total solar eclipse. The SEQP is a great opportunity for hams to contribute data to studies of Earth's ionosphere, the part of our atmosphere that makes radio communications possible, and all you have to do is get on the air and operate as you normally would. The lead organizer of Ham Radio Science Citizen Investigation (HamSCI), Dr. Nathaniel Frissell, W2NAF, joins us in this episode to explain how to get involved.

In Brief...

Blind amateur radio operator, tower climber, and Southeastern Repeater Association (SERA) President Wade "Danny" Hampton Jr., K4ITL, passed away February 28, 2024.

While attending the North Carolina State School for the Blind (now known as Governor Morehead School for the Blind) in Raleigh, Hampton met several sighted friends involved in the amateur radio community and began attending radio club meetings with them. As a result, he became a licensed amateur radio operator at the age of 12, despite the requirement that an operator must be able to read, copy, and send Morse code, all of which he learned by ear. After graduation from Wake Technical Community College, Hampton founded a company that maintained commercial two-way radio systems across the southeastern US. For many years, he was a broadcast engineer for WRAL-TV in Raleigh, often working at the top of the station's 2,000-foot tower. Hampton made his last climb in 2023 at the age of 79. He was named Hamvention® Amateur of the Year in 2009 for his design of the Piedmont Coastal Repeater Network, which links more than 40 repeaters. He was also awarded North Carolina's highest civilian award, The Order of the Long Leaf Pine, in recognition for adding broadcast translators to the fringe service area of the Raleigh National Weather Service office. He leaves behind his wife Rose, six children, 11 grandchildren, and five great grandchildren.
