Hawaii ARES Drill Tests All Communications

The Hawaii Amateur Radio Emergency Service® (ARES®) conducted an operational readiness drill on April 16 to evaluate their emergency communications abilities if severe weather were to hit the state and disable regular communications.

The exercise simulated a 4-day period of catastrophic rain and wind covering the Hawaiian Islands, from Kauai to the Big Island, which took out power, internet, and cell phone towers. State, local, and federal agencies participated in the exercise to evaluate ARES members and non-members for radio operations and procedures.

ARRL Director of Emergency Management Josh Johnston, KE5MHV, expressed that it's important for all agencies to work together during emergencies. "It is great to see ARES work this closely with local and state government agencies to overcome obstacles and provide emergency communications for the public," Johnston said. "Hawaii faces challenges that are different than other areas, but the general practice of preparing and exercising is the same anywhere you go."

The Hawaii Office of Homeland Security (OHS) participated in the drill, and OHS Administrator Frank Pace echoed the importance of all agencies working together. "We support the statewide training of amateur radio operators as part of the Incident Command System (ICS) structure, and the deployment of radio stations operated by volunteers, in preparing for disaster situations," he said.

There are 3,800 amateur radio operators in Hawaii, and OHS Statewide Interoperability Coordinator Everett Kaneshige said that coordinating all efforts is critical. "It is exciting to see the incorporation of innovative technology, such as the amateur radio-developed GPS software mapping capabilities," said Kaneshige. "Having multiple outlets for communication during a crisis is critical."

An article about the exercise was published by KITV 4 Island News.

ITU Celebrates 2022 World Amateur Radio Day

In recognition of World Amateur Radio Day, held on April 18, the International Telecommunication Union (ITU) published articles and social media posts highlighting various facets of ham radio. This included an ITU News interview with Philipp Springer, DK6SP, Chair of the International Amateur Radio Union (IARU) Region 1 Youth Working Group, and the article, "How to become a radio 'ham' in the digital era," by Nick Sinanis, SV3SJ, ITU Study Group Advisor and head of the ITU radio station, 4U1ITU.

Springer, age 24, earned his ham radio license when he was 9 years old. In his interview with ITU News, he explained the variety of operating techniques and social connections is part of what motivates young people to become active in ham radio in an increasingly digital world. "It's technical parts like experimenting with radio science, soldering, developing, and building electronics, in practice and not just theory," he said. "Secondly, it's [the] social part: we are connecting with other communities, meeting radio operators from all around the world. Lastly, we connect with other cultures: we practice foreign languages, visit other countries, and get on the air at so-called 'expeditions.'" Springer is also featured in an ITU video on YouTube.

In his article, Sinanis explained that "ITU plays a key role in amateur radio by overseeing the standardization and regulatory processes of the radiocommunication sector (ITU-R), with special emphasis on its utility in emergency communications." The ITU is the United Nations specialized agency for information and communication technologies, and the International Amateur Radio Union (IARU) contributes to the work of the ITU as a Sector Member. World Amateur Radio Day marks the annual anniversary of the IARU, formed in Paris on April 18, 1925.

The ITU also celebrated World Amateur Radio Day via posts on Twitter:

On April 15, 2022, ARRL President Emeritus Harry Dannals, W2HD, celebrated his 95th birthday, as well as over 80 years of involvement in amateur radio. He served as ARRL President for 10 years, from 1972 - 1982, and the President Emeritus status was conferred in 1984.

Dannals is the only person to have served as president to both ARRL and the Quarter Century Wireless Association (QCWA). He is an ARRL Life Member, and he is the oldest member of the Albemarle Amateur Radio Club, which boasts 175 members.

In an interview, Dannals said that when he was 10 years old, he practiced Morse code with his best friend and was able to master 50 - 60 words per minute.

On his birthday, he was visited by his friend, Jim Wilson, K4BAV, and his son, Bob Dannals, W2GG, who holds a Ph.D. and is a professor in the Johns Hopkins Medicine Department of Radiology and Radiological Science in Baltimore, Maryland.

Harry Dannals summarized his lifetime of experiences with amateur radio with the simple statement, "I've had fun."

The Ohio ARES NVIS Antenna Day
is scheduled for April 23, 2022, from 10 AM through 4 PM EDT. The purpose of Antenna Day is to learn about, construct, and test Near Vertical Incident Skywave (NVIS) antennas, as well as to evaluate the ability to conduct communications within a confined geographic area -- usually about 400 miles or less. NVIS antennas, or cloudburners, are very low wire antennas. Because they are close to the ground, the signal is reflected vertically and bounces back off the ionosphere very close to the original location. It is a great time to teach beginners the art of building antennas from scratch, including measuring, cutting, soldering, and deploying. These skills will come in handy throughout their ham radio career. For more information, contact

The North American SSB Sprint Contest begins April 24, 0000 UTC, and concludes at 0400 UTC.
The four-hour contest, on the 80-, 40-, and 20-meter bands, are short, intense competitions that challenge the best operators, while allowing others to sharpen their contesting skills. Operators who have never participated in the Sprints before should take a look at the Tips & Tricks section of the SSB Sprint website. For complete rules, visit

A Ham Radio and Scouting Training Conference
will be held July 10 - 16, 2022, at the Philmont Scout Training Center in Cimarron, New Mexico. The course is designed to familiarize current Scouts who are hams, as well as unlicensed Scouts, with the benefits and fun associated with ham radio, and its introduction into the Boy Scouts of America (BSA) program. Since 1918, 200,000 Scouts have received the Radio Merit Badge (formally known as the Wireless Merit Badge), introducing them to radio technology, communication, and amateur radio. The course is $470 plus housing. More about the course and the schedule can be found at

The K7RA Solar Update

Solar flares emerged daily over the last reporting week. On April 20, 2022, reported "Solar Activity is Intensifying," and over the past 24 hours, there were 19 solar flares, including six M-class events, and a powerful X2.2-class solar flare.

Daily sunspot numbers averaged 64.4, 30 points higher than last week, and average daily solar flux also rose 30 points from 103.1 to 133.1.

Even with all flares and coronal mass ejections (CMEs), geomagnetic indicators were lower, with average planetary A index going from 16.9 to 14.6, and middle latitude numbers dropping from 12.6 to 10.9.

Predicted solar flux looks moderate, at 130 on April 21 - 27; 132 on April 28; 125 on April 29 - 30; 130 on May 1 - 4; 125 on May 5; 130 on May 6 - 7; 128 on May 8; 130 on May 9 - 10; 135 on May 11 - 12; 140 on May 13 - 14; 135 on May 15; 130 on May 16 -18; 135 on May 19; 130 on May 20 - 21; 135 on May 22, and 132 on May 23 - 25.

Predicted planetary A index is 5 on April 21 - 22; 12 on April 23; 8 on April 24 - 26; 5 on April 27 - 28; 18, 12, and 8 on April 29 - May 1; 5 on May 2 - 5; 8, 15, 12, and 8 on May 6 - 9; 5 on May 10 - 12; 8, 10, and 12 on May 13 - 15; 10 on May 15 - 17; 8 on May 18 - 19; 12 and 8 on May 20 - 21, and 5 on May 22 - 25.

Sunspot numbers for April 14 - 20 were 37, 35, 78, 74, 79, 68, and 80, with a mean of 64.4. The 10.7-centimeter flux was 103.4, 110.3, 122.4, 134.9, 140.5, 160.1, and 160, with a mean of 133.1. Estimated planetary A indices were 38, 21, 8, 11, 8, 7, and 9, with a mean of 14.6. Middle latitude A index was 22, 14, 7, 9, 7, 8, and 9, with a mean of 10.9.

A comprehensive K7RA Solar Update is posted Fridays on the ARRL website. For more information concerning radio propagation, visit the ARRL Technical Information Service, read "What the Numbers Mean...," and check out the Propagation Page of Carl Luetzelschwab, K9LA.

A propagation bulletin archive is available. For customizable propagation charts, visit the VOACAP Online for Ham Radio website.
