Students to Promote Collegiate Amateur Radio at the 2024 ARRL National Convention at Dayton Hamvention®

Young adults planning to attend the 2024 ARRL National Convention at Dayton Hamvention® can look forward to meeting many other young hams at the event, including college students representing the ARRL Collegiate Amateur Radio Program (CARP). The convention is on May 17 - 19, 2024, at the Greene County Fairgrounds and Expo Center in Xenia, Ohio.

CARP will occupy a booth in the large ARRL exhibit area, which will be staffed with college students and advisors for the program. CARP will also have a forum at the end of the ARRL Youth Rally on Saturday, May 18, at 4 PM in Forum Room 3. The forum will be followed by a pizza party at a nearby restaurant.

"The CARP booth will be a great place to connect with other college-aged hams, and to learn more about the extensive network of college amateur radio clubs across the nation," said Andy Milluzzi, KK4LWR, from Clermont, Florida.

Andy and his brother Tony Milluzzi, KD8RTT, from Lenexa, Kansas, are co-advisors for CARP, and they moderate a monthly Zoom meetup to help network college radio clubs. The brothers have recruited many college students who are regular CARP participants to support the booth and related activities at Hamvention.

Morgan Lyons, KI5SXY, is one of the volunteers. She's a student at the Missouri University of Science and Technology and a very active radio amateur. "I'm super excited to be working with ARRL at the CARP booth at Hamvention! This will be my second time at Dayton Hamvention, and I had so much fun last year. I'll also be helping with the Collegiate Amateur Radio Forum," she said.

The energy around CARP is exciting. Lyons, whose other interests include rocketry, is an aerospace engineering major and serves as president of the ARRL-affiliated Missouri S&T Amateur Radio Club, W0EEE, which recently celebrated 100 years of existence. She says that legacy is one she's proud to carry at the National Convention. "I love representing the college students in ham radio and showing folks that ham radio [will continue with the future generations]!"

Additional student volunteers will include Andrej Antunovikj, K8TUN, and Adam Goodman, W7OKE, both undergraduates attending Case Western Reserve University in Cleveland, Ohio, and members of the Case Amateur Radio Club, W8EDU -- also an ARRL Affiliated Club. "I'm looking forward to going to an amateur radio convention and meeting other students from the CARP program in-person," said Antunovikj.

The ARRL Collegiate Amateur Radio Program is sponsored in part by the W1YSM Snyder Family Collegiate & ARRL Affiliated Club Endowment Fund. The program was first established in 2017, and today includes an extensive community of participating students, alumni, and faculty. In addition to its monthly Zoom meetups, students can make connections through the ARRL CARP Facebook group and Discord. For more information about CARP, visit

MFJ Ceasing On-Site Production

MFJ Enterprises, Inc. founder Martin F. Jue, K5FLU, announced that as of May 17, 2024, the company will cease on-site production at their Starkville, Mississippi, facility. Ameritron, Hy-Gain, Cushcraft, Mirage, and Vectronics brand products will be affected by the shutdown.

In a letter posted to social media, Jue said he is looking forward to retiring:

Times have changed since I started this business 52 years ago. Our product line grew and grew and prospered. Covid changed everything [for] businesses, including ours. It was the hardest hit that we have ever had, and we never fully recovered.

I turned 80 this year. I had never really considered retirement, but life is so short, and my time with my family is so precious.

Jue founded MFJ Enterprises in 1972, after building a CW filter kit that sold for less than $10. Since 1990, the company has acquired several other legacy brands within the amateur radio market. Jue shared that the company will remain open to sell existing inventory because they have "a lot of stock on hand." They will also continue to offer repair services for the foreseeable future.

Jue expressed gratitude to the many longtime employees of MFJ, some of whom have been with the company for 40 years.

He also thanked MFJ dealers and radio amateurs for their patronage over the decades.

He also sent a special message to ARRL Members and loyal QST readers:

"I give my deepest heartfelt thank you to my fellow hams all over the world, and especially to ARRL members and QST readers. In my youth, I was given a second-hand set of 1958 QSTs. I read them over and over until I practically memorized every word. This gave seed to MFJ.

MFJ became a worldwide ham radio leader only because of you. As I turned 80, I cannot thank you all enough for 52 wonderful ham radio years. Thank you, 73s . . . Martin F. Jue, k5flu"

Changes in the ARRL San Joaquin Valley Section

Steven Hendricks, KK6JTB, has been appointed as Section Manager of the ARRL San Joaquin Valley Section.

Section Manager of the ARRL San Joaquin Valley Section, Steven Hendricks, KK6JTB.

He fills the vacancy left by John Litz, NZ6Q, who was appointed as Vice Director of the ARRL Pacific Division.

Hendricks has always had a love for radio, and he first earned his amateur radio license a decade ago. "In 2014, I became licensed as a Technician, and in 2015 I became a General," he said. Hams in the area helped him get active in the local radio community. He held several elected leadership positions within the Sierra Amateur Radio Club, an ARRL Special Service Club.

"With amateur radio, it's easy to operate in many different ways. Currently I'm having fun on HF all while exploring FT8, Winlink, and emergency communications," said Hendricks.

Hendricks has previously served as an Assistant Section Manager. His appointment was effective on April 24, and it will run through the remaining term until June 31, 2025.

Storms and Tornadoes: Amateur Radio Ready

Strong storms and reports of at least 60 tornadoes have wreaked havoc in the Central U.S. for nearly two weeks. Homes and businesses across Nebraska, Oklahoma, Texas, Missouri, and Iowa were destroyed, and power is still down for more than 30,000 residents. On May 1, 2024, President Joe Biden declared a major disaster exists in Oklahoma, making federal aid available to those affected by last weekend's severe storms in Hughes, Love, and Murray counties.

Section Manager of the ARRL Iowa Section Lelia Garner, WA0UIG, reported that in Iowa, they have moved from response to recovery. Currently, nine counties are under the Iowa State Individual Assistance Grant Program and the Disaster Case Advocacy Program.

"Amateur Radio has served our local agencies well. We recently networked at a central Iowa hamfest and are building our emergency communications capacity primarily through [the Amateur Radio Emergency Service® (ARES®). ARES resources [include] personnel, experience, meetings, training, [communications] equipment, [and] operating trailers. The opportunity to share our experience and knowledge gained in the field has been critical to supporting ARES in Iowa," said Garner.

Garner added that awareness is the best tool. She stressed that amateur operators and ARES members work to help the National Weather Service and other served agencies in order make their work and the community safer.

ARRL Emergency Management Director Josh Johnston, KE5MHV, agrees that everyone should stay vigilant in their awareness and preparations, even during periods of less activity. Make sure you are prepared at home and that your family has a severe weather plan. This is extremely important if you plan to be mobile or away from your home during a severe weather event. Your safety is the most important thing if you plan to be active during severe weather. Every ham who is interested in severe weather should take the SKYWARN storm spotting class offered by the National Weather Service," said Johnston.

He added that some of the most important aspects of preparation are communication and building relationships. These activities, including drills and exercises, need to be done during blue - sky days to ensure you will be ready during days with severe weather.

The ARRL Learning Center offers courses like on Basic EmComm and Intro to Radio for Emergencies & Disasters.

The High-frequency Active Auroral Research Program (HAARP) will be conducting a new research campaign on May 8 - 10, 2024, and amateur radio operators can participate by monitoring signal reports. Using high-powered transmitters located at the HAARP facility at the University of Alaska Fairbanks, HAARP transmissions will be between 2.8 MHz and 10 MHz, although operating frequencies and transmitting times may vary depending on propagation. Transmitting times scheduled on May 8 - 9 are 2000 - 0200 UTC and 2000 - 0230 on May 10. The experiment is designed to study mechanisms for the detection of orbiting space debris, which are a major risk to space operations, including manned spacecraft and communications satellites. The experiments being performed at HAARP will help identify ways to improve collision detection on satellites. Amateur radio operators, shortwave listeners, and radio astronomers with receivers or software-defined receivers (SDRs) capable of 8 MHz bandwidth can monitor the entire frequency band during the experiments and report band conditions. A HAARP QSL card for reception reports will also be available to those who send reports to: HAARP, P.O. Box 271, Gakona, Alaska 99586 USA. More information about HAARP experiments can be found at FAQ | HAARP (

In Brief...

The Tennessee Maneuvers special event station, W4T, will be in operation on May 3 - 5 from 1300Z to 0100Z on AM and CW. The event honors a former military training area where more than 850,000 troops trained for WWII. The location was selected because the terrain closely resembled locations in Germany, France, and Belgium where part of the war was fought. Frequencies may change, and updated information can be found at The location, in downtown Carthage, Tennessee, will be open to the public on Saturday, May 4, and it will feature displays of WWII radio equipment and other memorabilia.
