Every April 18, something quietly remarkable happens on the bands. From a small QRP station in a backyard in Yorkshire to a multi-operator contest setup in the Pacific, tens of thousands of licensed operators fire up their rigs for the same reason: to mark the day, in 1925, when a handful of radio pioneers met in Paris and founded the International Amateur Radio Union.
A hundred and one years later, we are still here. Still on the air. Still listening.
This year’s World Amateur Radio Day comes with a theme that feels particularly well chosen: “Advancing the Spirit of Amateur Radio Through Innovation”. Coming right after the IARU’s centenary in 2025, it is less a celebration of the past and more an invitation to think about what the next hundred years of amateur radio might look like.
The day we almost lost the shortwaves
It is worth remembering why April 18 matters at all. In the early 1920s, amateur experimenters had just discovered that the “useless” short wavelengths could, in fact, carry signals around the world. Commercial and government interests noticed. Fast. There was a very real risk that amateurs would be squeezed out of the spectrum entirely.
The IARU was founded precisely to prevent that. Two years after Paris, at the 1927 International Radiotelegraph Conference, amateur radio was granted the allocations we still use today: 160, 80, 40, 20 and 10 meters. Every contact you make on those bands is, in a sense, a direct inheritance from that fight.
Early amateur experimenters proved that shortwave could circle the globe — and fought to keep it.Innovation is not new to us
The 2026 theme is sometimes read as a call to embrace new digital modes, new software-defined platforms, new satellite constellations. It is all of that — but it is also a reminder that innovation has always been what amateurs do.
The hams of the 1920s innovated out of necessity: they had been given the scraps of the spectrum and had to make them work. The hams of the 1960s built repeaters and pushed into VHF and UHF. The hams of the 1980s put packet radio on the air before most people had heard of the internet. The hams of the 2010s gave us FT8, which quietly rewrote what “weak signal” means on HF.
In 2026, the next step is already being discussed in forum threads and on-air conversations: experimental modes like FT2, more capable open-source SDR platforms, low-power digital operation from portable sites, machine-learning-assisted decoders, mesh networking on VHF and UHF. None of these will replace CW or SSB. They will sit alongside them, as every innovation in this hobby eventually does.
What to do on April 18
World Amateur Radio Day is not a contest, and there are no points to chase. But there are a few things worth doing:
Get on the air. Even a single QSO on 20 meters counts. Call CQ and mention WARD in your exchange; you will find operators happy to ragchew about it.
Look for special event stations. National societies across all three IARU regions put commemorative stations on the air every year. Many issue electronic certificates for a confirmed contact – a nice touch for your digital shack wall.
Open your station. ARRL is again encouraging clubs to host Ham Radio Open House events throughout April. If your local club is participating, bring a friend who has never seen a real HF rig at work. The hobby grows by demonstration, not by advertising.
Try something new. The theme is innovation. Spin up an SDR receiver you have never used. Decode a mode you have been curious about. Work a satellite pass. Try POTA from a park ten minutes from home. The point is to do something slightly outside your comfort zone – the same thing the Paris founders did, on a much larger scale, in 1925.
More than a hobby
Every year, on April 18, it is tempting to make big speeches about what amateur radio means. The truth is simpler. In a world that routes almost every conversation through commercial infrastructure, three million licensed operators still maintain the knowledge, the equipment and the spectrum to communicate without any of it. That is unusual. It is worth preserving. And it is worth celebrating.
So tomorrow, make a contact. Listen to a band you usually ignore. Say 73 to someone you have never worked before.
The spirit advances one QSO at a time.
Saturday, April 18, 2026, from 0000 UTC to 2359 UTC.
“Advancing the Spirit of Amateur Radio Through Innovation.”
It commemorates the founding of the International Amateur Radio Union in Paris on April 18, 1925.
No. WARD is a celebration, not a contest. Any on-air activity counts — a single QSO, a club event, a demonstration for newcomers.
