2023 ARRL Field Day Was a Success

2023 ARRL Field Day is in the books and from all indications, it was a success!

Social media is buzzing with stories and photos from around the country.

Results are coming in, and so far, 2,548 Field Day entries have been received. You can see a live, up-to-the-minute count of the entries, comments, and photos on the Field Day Entries Received web page.

Participants have been submitting photos and descriptions of their stations and setups to the SOAPBOX column. Below are just a few of the many Soapbox received so far.

William Roy, K1YOR:

"I used a Yaesu FT-450D, 100, and an

[MFJ] G5RV Junior [antenna] in the near vertical incidence skywave configuration. It was basically horizontal. The average height was about 14 to 18 feet above the ground, broadside was north/south, and the ends were pointing east and west. Because I was inside, the antenna could not be extended in a normal fashion. I used rubber standoffs and non-metal furniture to support the antenna.

Thomas Hardy, NN7O:

"This was my first year participating in Field Day. [I] operated CW [low power] from eastern California. I am still a new CW operator, and while I am getting better, I appreciate everyone's patience. I was using my KX2 into a 40-meter [end-fed-half-wave] setup as an inverted v. [It] seemed to work well. [I got] more east coast contacts than I expected!"

Thomas G. Azlin's, W7SUA, Field Day setup.

Thomas G. Azlin, W7SUA:

"I set up at our family cabin on the Mogollon Rim [Trail] near Show Low [in Arizona]. [I] used an [Elecraft] K3, [a] Goal Zero Yeti 1500X battery/inverter, [a] 200 -W solar panel for daytime charging, and an [MFJ] G5RV Junior [antenna] strung up in pine [trees] with pre-existing ropes and pulleys. [I] split my time between JS8 and FT8 on 40, 20, and 15 meters. [It was a] nice Field Day, [and] fun!"

Like many ARRL Field Day sites, the Hampden County Radio Association (HCRA) in Massachusetts welcomed guests to their event. They got more than they bargained for, though, when a black bear showed up and started helping itself to their food!

More stories and updates are on the way. Check out the ARRL News web page for the latest on 2023 Field Day!

ARRL Affiliated Clubs and members opted into the Club newsletter via email were automatically entered by purchasing ARRL Field Day merchandise or submitting an entry through an online form. Mike was the lucky winner, and displayed the banner at his club's site.
"The banner made our Field Day site much easier to find. We had decent enough foot traffic that I forgot to take more pictures. In a way... that's a "Win!" - because I got to share the hobby with more people," wrote Moore.
2023 AMSAT Field Day

2604 AMSAT Field Day is over, and early data shows how the satellites were utilized.

It has been many years since there were more than one or two Field Day submissions from outside North America. This year, immediately after of Field Day ended, there were two submissions from Japan.

The satellites worked well. The FM Tevel family of satellites and GreenCube seemed to be popular. SO-50, AO-91, and the International Space Station were also busy with their FM single channel. DOSAAF-85 (RS-44) was quite tame, with plenty of bandwidth for many to make contacts, whether they were sitting on a frequency and calling CQ or using the hunt-and-pounce method.

More data is on the way. For updates, visit the AMSAT website. A special thanks to Bruce Paige, KK5DO, for the information provided in this story.

ARRL Section Managers Prepare for New Terms

When the nomination period for the summer ARRL Section Manager election cycle concluded on June 9, 2023, there was only one candidate for each of the Sections up for election.

The following incumbent Section Managers were declared re-elected to new 2-year terms starting on October 1, 2023:

  • Amanda Alden, K1DDN, Colorado.

  • Jo Whitney, KA7LJQ, Eastern Washington.

  • Diana Feinberg, AI6DF, Los Angeles.

  • Carol Milazzo, KP4MD, Sacramento Valley.

  • Dan Ringer, K8WV, West Virginia.

  • Stuart Wolfe, KF5NIX, South Texas.

  • Monte Simpson, W7FF, Western Washington.

Kevin Kerr, W1KGK, of Plains, Montana, was the only nominee for the ARRL Montana Section, and he will be taking the reins of the Montana Field Organization on October 1. Kerr is presently serving as Section Emergency Coordinator of the Montana Section and as a District Emergency Coordinator within the Section. Paul Stiles, KF7SOJ, decided not to run for a new term. Stiles, of Billings, Montana, has been Section Manager of the Montana Section since 2019.

Dr. Antonis Papatsaras, AA6PP, of Larkspur, California, will become the Section Manager of the San Francisco Section on October 1 because he was the only nominee. He currently is an Assistant Section Manager of the ARRL San Francisco Section and has been President and Director of the San Francisco Radio Club.

Bill Hillendahl, KH6GJV, of Santa Rosa, California, decided not to run for another office term after serving as Section Manager of the San Francisco Section for 20 years.

Section Manager of the Oregon Section David Kidd, KA7OZO, has decided to step down from the role for personal reasons. He was first appointed to the position on July 1, 2018. Effective July 1, 2023, Jonathan Wanzer, KK6GXG, will fill the role for the remainder of the current term.

Jonathan Wanzer, KK6GXG, new Oregon Section Manager as of July 1, 2023.

Wanzer stated, "Homebrew radios, tools, and antennas are not my only interests in the Amateur Radio Service. I like to share with others; I teach license classes and introduction to Emergency Communications (EC-001). I am an active Volunteer Examiner... I also have the honor of serving fellow hams as the Klamath County Emergency Coordinator and as the Assistant Section Manager for [the Oregon Section]. One of my greatest privileges is in developing contacts and relationships with non-ham groups and providing presentations and information on amateur radio and all it has to offer their members, and the community at large, through the Civil Defense Communications Auxiliary."

Wanzer, of Klamath Falls, will serve as Section Manager of the Oregon Section through June 30, 2024.

ARRL would like to thank Kidd for his years of dedicated service as a volunteer, and for his hard work as a Section Manager.

HAM RADIO in Germany Draws International Crowd

The 46th annual International Amateur Radio Exhibition, HAM RADIO, attracted more than 11,000 visitors to Friedrichshafen, Germany, June 23 - 25, 2023.

Attendees queue up at the ARRL booth to have their QSL cards checked for DXCC and other ARRL awards.

ARRL, which has nearly 7,000 international members, sends a small delegation to the convention each year -- greeting members and friends from the global amateur radio community, and networking with other national radio societies. ARRL representatives included President Rick Roderick, K5UR and his wife Holly Roderick; CEO David Minster, NA2AA; Director of Operations Bob Naumann, W5OV, and Director of Marketing and Innovation Bob Inderbitzen, NQ1R.

(Left to right) Lili, HA2LY, and Nóri, HA5YN, were among the youth attendees at 2023 HAM RADIO and who visited the ARRL stand. Both will participate in the Youngsters on the Air (YOTA) camp in Hungary, to be held in August.

Messe Friedrichshafen Managing Director Klaus Wellmann and Project Manager Petra Rathgeber were delighted with the success of the event.

"HAM RADIO lived up to its reputation as Europe's largest amateur radio exhibition. In cooperation with the German Amateur Radio Club (DARC), the perfect partner for the event, we showed that amateur radio plays an important role in society," said Wellmann and Rathgeber. "This year's slogan, 'We're all about STEM!' was brought to full fruition, with many activities focusing on work with young people -- something that really brought in the crowds."

The convention draws attendees from around the world. In this photo, ARRL Life Member and Diamond Club donor John Gagen, W2YR (middle) is flanked by President Rick Roderick, K5UR (left) and CEO David Minster, NA2AA (right). Gagen operates as HS0ZDJ when in Thailand.

A recent press release from HAM RADIO said young attendees were able to tinker and make things under guidance, and they were also able to test their knowledge in the Ham Rally, a technical scavenger hunt featuring 25 stations. Students were encouraged to try sending Morse code, and pass the QSL card quiz. ARRL participated in the Ham Rally, challenging young people to name and identify the US states.

"We were really happy with the way this year's exhibition went," said Christian Entsfellner, DL3MBG, Chairman of DARC.

A total of 392 participants, including 149 commercial exhibitors and international associations, as well as 243 flea market exhibitors, represented the unique diversity of amateur radio around the world.

Plans are already being made for next year's HAM RADIO to be held June 28 - 30, 2024. More information is available at HAM RADIO.

FCC ULS System Restored

The FCC Universal Licensing System (ULS) has resumed operations, including the Electronic Batch Filing (EBF) system.

As of June 27, 2023, all systems have been reported to be working. However, visitors to the website will see a message referring them to Public Notice DA-23-529 for additional information and guidance on filing deadline extensions.

The systems were first reported unavailable on June 9, 2023. On Friday afternoon, June 23, the EBF system was restored. All VEC organizations use that system for filing exam sessions, individual applications, and club license applications. ARRL VEC staff worked late into Friday night to ensure all backlogged sessions and application files were transmitted to the FCC before the weekend. Approximately 350 backlogged files were successfully submitted to and processed by the FCC before the system's normal shutdown at 8 PM.

ARRL is still monitoring the ULS, and any further updates will be available at ARRL News.

The Big Bang Theory Antenna Lives On

An antenna that holds an important place in scientific history sits on a small parcel of land on Crawford Hill in Holmdel Township, New Jersey.

1959 by Bell Labs (now Nokia Bell Labs) researchers. It was originally designed to bounce radio signals off of reflective satellite balloons for long-distance communication. It worked, and the Holmdel Horn Antenna was no longer needed.

Two Bell Labs astronomer employees, Arno A. Penzias and Robert W. Wilson, received permission in 1965 to use the antenna to search for radio transmissions in outer space. They pointed the antenna toward what was considered a quiet area, but what they discovered was anything but quiet. They discovered Cosmic Microwave Background radiation, which provided evidence for the Big Bang Theory.

Now, there is a historical marker at the site, but there has been some dispute as to who owns the antenna and surrounding land. In mid-June 2023, the Holmdel Township Committee voted unanimously to approve resolutions that will begin the process of acquiring two of the three parcels that make up the Crawford Hill property. The township committee is leaving the third parcel to be part of the redevelopment toward preserving Crawford Hill as a public park to celebrate the horn antenna's place in scientific history.

In Brief...

The Harbin Institute of Technology (HIT) in China is developing a new lunar amateur radio satellite.
Lunar OSCAR II is a lunar amateur radio payload being developed by a team that consists of students from HIT and international amateur radio enthusiasts. Its baseline functions include telemetry, digital image downlink from an infrared camera, and a digipeater with JT4G uplink/downlink. It will also provide chances to upload and test new waveforms and algorithms for radio communications and measurements across very long distances. Amateur radio orbit determination experiments, like the Very Long Baseline Interferometry (VLBI), are also possible with these links. HIT has previously successfully developed the first lunar amateur radio satellite, Longjiang-2/DSLWP-B. As a subsequent mission, Lunar OSCAR II will continue offering various resources for communications relay and amateur radio research, and it will help promote amateur radio to communities. The Lunar OSCAR II payload will be onboard a lunar microsatellite with a volume of about 300x200x100 cubic millimeters and a mass of about 14 kilograms. It will utilize downlinks on UHF for telemetry and images by using 250/500 baud GMSK with turbo codes, as well as a digipeater that uses 4.375 baud FSK with convolutional coding (JT4G). More information is available at The satellite is planned to launch from Wenchang, China, in 2024. A downlink on 437.750 MHz has been coordinated.

Thanks to the IARU and HIT for the above information.

The K7RA Solar Update

Tad Cook, K7RA, of Seattle, Washington, reports for this week's ARRL Propagation Bulletin, ARLP026:

Conditions were favorable over Field Day weekend, with the exception of a brief period where planetary K index was at 5 on Saturday night.

Solar disk image taken June 29, 2023, courtesy of NASA SDO/HMI.

There were five new sunspot groups on June 23, two more on June 24, another on June 26, and another on June 27.

Average daily sunspot numbers were up, and solar flux was down.

The average daily sunspot number rose from 143 to 170, and the average daily solar flux declined slightly from 165.4 to 160.3.

This was unexpected because we normally see these values track together.

Predicted solar flux is 155 on June 29; 150 on June 30 through July 4; 145 on July 5; 135 on July 6 - 8; 145, 155, 160, 165, and 170 on July 9 - 13; 175 on July 14 - 18; 170 on July 19 - 21; 160, 150, 145, 145, 140, and 135 on July 22 - 27, and 130 on July 28 - 31.

Predicted planetary A index is 5 on June 29 - 30; 15 and 10 on July 1 - 2; 5 on July 3 - 7; 12 and 8 on July 8 - 9; 5 on July 10 - 11; a stormy 20 and 30 on July 12 - 13; 8 on July 14 - 23; 12 on July 24 - 25, and 8 on July 26 - 27.

Sunspot numbers for June 22 - 28, 2023, were 176, 194, 200, 180, 158, 141, and 141, with a mean of 170. 10.7-centimeter flux was 173.2, 169.7, 160.8, 154.8, 157.7, 151.2, and 154.9, with a mean of 160.3. Estimated planetary A indices were 8, 9, 16, 15, 11, 8, and 8, with a mean of 10.7. Middle latitude A index was 8, 9, 16, 10, 11, 7, and 8, with a mean of 9.9.
