It is finished — and already missed. The 74th annual Dayton Hamvention, held at the Greene County Fair and Expo Center in Xenia, Ohio, came to a close this past weekend, leaving behind a fairground full of memories, friendships renewed and forged, and a quiet sense of awe at just how far a radio signal can travel.
From the moment the gates opened on Friday morning, it was clear this year's gathering was something special. Crowds poured in from across the United States and more than 43 countries around the world — engineers and experimenters, retired servicemen and curious teenagers, seasoned DX chasers and brand-new licensees. Every walk of life. Every mode of communication. All converging on a single fairground in Greene County, Ohio, united by one invisible thread: the radio wave.
It doesn’t matter where you’re from — we can still have fun, talk on the radio, talk around the world, and just be friends. — Hazel Everetts, Assistant General Chairperson, Hamvention 2026
A gathering unlike any other
Hamvention is often called the world’s largest amateur radio convention, and the numbers bear that out. Thousands of attendees filled the exhibit halls, forums, and the sprawling flea market tucked inside the fairground’s horse track infield — with official final attendance figures still being tallied at the time of this writing. Over 350 vendor booths offered everything from brand-new transceivers to decades-old components, with 162 vendors representing the full spectrum of the hobby.
But statistics tell only part of the story. Walk through any aisle of the flea market, sit in on any forum, and you quickly understand that Hamvention is less about equipment and more about people. Friendships maintained year after year over the same crowded tables. Mentors passing knowledge to newcomers who didn’t know, six months ago, what a feedline was. Young operators discovering that this hobby has no ceiling.
Hamvention is the annual pinnacle event of our hobby. It is an honor to work with a great team to make this a successful event. Each year we work on improving the event. It takes a team of dedicated volunteers who share the passion and love of Amateur Radio. I encourage everyone that loves this hobby to get involved! — Jack Gerbs, WB8SCT · Hamvention 2026 Executive Committee
The next generation takes the stage
Among the most inspiring moments of the entire weekend was the Radio Club of America Youth Forum — a Saturday morning tradition that has run for more than three decades, and one that never fails to silence a room full of seasoned operators with nothing more than the enthusiasm of a ten-year-old at a microphone.
Founded and guided for many years by legendary amateur radio educator Carole Perry, WB2MGP — a Fellow and Director of the Radio Club of America, past Hamvention Ham of the Year, and ARRL Instructor of the Year — the RCA Youth Forum brought together carefully selected young ham radio operators, some barely out of elementary school, to deliver polished and passionate presentations on their work within the hobby. Topics ranged across the full breadth of amateur radio: satellite communications, high-altitude ballooning, antenna construction, digital modes, emergency preparedness, and the inspiring mission of bringing ham radio into schools and communities across the globe.
SPOTLIGHT — RCA Youth Forum
Each year, seven to eleven young operators — some as young as nine or ten — take the Hamvention stage to share their experiments, achievements, and passion for the hobby. The forum is consistently one of the most well-attended and warmly received events of the entire weekend.
The audience was captivated. Here were young people who had built their own antennas, chased DX across continents, bounced signals off the moon, and worked satellites passing hundreds of miles overhead — presenting their accomplishments not as hobbies, but as serious scientific and technical endeavors. The room was packed, and the applause was genuine.
The forum reached a remarkable crescendo when an astronaut took the stage to address the young presenters directly — urging them to dream bigger, reach farther, and recognize that the skills they were developing in amateur radio were the same skills that take human beings beyond the atmosphere. It was a moment that drew the connection between radio waves and space exploration into vivid, personal focus: a person who had orbited the Earth, looking out at a room of young operators who might one day follow a similar path.
The next generation of operators is already here — already curious, already building, already calling CQ.
For many in the audience, it was the single most memorable moment of Hamvention 2026. For the young presenters themselves, it may well have been the moment that set the trajectory of a lifetime.
The invisible world we inhabit
There is a particular joy in belonging to a community that understands what most people walk past without a second thought: that the air around us is alive with signals. Radio waves propagate through walls, across oceans, off the ionosphere, and out beyond the atmosphere entirely. Amateur radio operators don’t just use this invisible world — they know it, in a way that is almost devotional.
Every mode of amateur communication was on display at this year’s event. CW operators tapped out Morse code. Digital enthusiasts demonstrated FT8 contacts spanning continents on a fraction of a watt. Satellite operators tracked overhead passes. EME enthusiasts — moonbouncers — described reflecting signals off the lunar surface and catching the echo nearly three seconds later. The hobby, in its full breadth, is staggering.
From Xenia to interstellar space
No reflection on amateur radio and the wonder of electromagnetic communication would be complete without a thought toward the Voyager spacecraft. Launched in 1977 — the same era that shaped a generation of today’s operators — Voyager 1 is now more than 15.8 billion miles from Earth, deep in interstellar space, beyond the heliosphere, beyond the solar system itself. And yet we are still talking to it.
A radio signal sent from Earth today takes nearly 23.5 hours to reach Voyager 1. By November 15th of this year, the probe will cross a historic threshold: it will be a full light-day away — the first human-made object ever to reach that distance. A signal sent in the morning will arrive the following morning. A reply will not return until the day after that.
This is radio at its most humbling. The same fundamental principle — an oscillating electromagnetic field propagating through space — that lets a ham in Xenia, Ohio contact a counterpart in Tokyo is the very thing keeping humanity tethered to its most distant ambassador. The physics does not change. Only the distance grows.
- Distance to Voyager 1: 15.8 billion miles
- Signal travel time: 23.5 hours one-way
- In continuous operation: 49 years
600 volunteers, one community
None of this happens without the people who make it happen. More than 600 volunteers gave their time, their expertise, and their energy to produce Hamvention 2026 — directing traffic, staffing forums, manning information booths, setting up equipment, and doing the thousand invisible tasks that keep an event of this scale moving smoothly. They did it harmoniously, enthusiastically, and without any apparent desire for credit. That, too, is very much in the spirit of amateur radio.
The event also made a meaningful impact on the surrounding community. Hamvention generates an estimated $35 million in regional economic activity each year, filling hotels and restaurants and creating a visible surge of energy throughout Greene County. For the Miami Valley, this is not just a radio convention. It is an annual affirmation that Xenia, Ohio is, for one weekend in May, the center of a global conversation.
Until next year
The fairgrounds are quiet now. The vendors have packed their tables, the forums have ended, and operators from dozens of countries are making their way home — by plane, by car, by train — many of them already looking forward to May 2027, when Hamvention will return for its 75th year.
In the meantime, the radios will keep humming. Signals will keep traveling. Somewhere in the darkness between the stars, Voyager 1 will keep moving outward at 38,000 miles per hour, faithfully answering every call we send its way.
And somewhere in that audience at the RCA Youth Forum, a ten-year-old who just heard an astronaut tell them to reach for the stars is already thinking about what comes next.
We are a remarkable species. We built something that crossed into interstellar space, and we still talk to it every day. We gather by the tens of thousands to celebrate the art of sending a signal into the unknown. We do it peacefully. We do it joyfully. We do it together.
73, and we’ll see you in Xenia next May.
