SafecomLink Live AI Weather Over HF Radio

2026-06-07T00:00:00Z

The following is a message from SafecomLink:

SafecomLink has published a new case study documenting live AI-based weather routing over HF radio north of the Arctic Circle. Sailor Harley Soltes (LA/KN7H) used SafecomLink with a Pactor 4 link to access the Safie AI assistant from his vessel off the Norwegian coast — establishing a connection to a land station in Austria (OE3FQU) on 14.120 MHz, then reaching the open internet, with no cellular coverage, no satellite service, and no shore-side infrastructure.

The real-time two-way AI conversation provided wind forecasts and a day-by-day crossing comparison for the passage to Lofoten, Norway. After completing the passage, Soltes reported the AI forecast was more accurate than his usual weather apps and far faster than the WinLink email method he previously used.

This is pretty game-changing — to have fast Pactor 4 communication from sea to a real-time internet AI connection. — Harley Soltes, LA/KN7H

Number of Amateur Radio Operators in Japan Continues Decline

2026-06-01T00:00:00Z

The number of amateur radio stations in Japan continues to decline. The Ministry of Internal Affairs and Communications announced the latest numbers for the first quarter of 2026 showing a steady reduction of 1,000+ stations each month. Over the last 10 years Japan's station count has reduced by more than 100,000 from 435,969 in January 2016 to 332,120 in January 2026.

While an explanation for the decline was not given, Japan has seen significant population loss over the last several years including a reduction of 3 million citizens over the past 5 years.

From Spot to Map: A New Way to Follow DXpeditions

2026-05-30T00:00:00Z

A new feature has been added to DXLook that allows amateur radio operators to visualize DXpedition activity on a world map using live reception reports from multiple amateur radio networks.

The new DXpeditions View combines data from PSK Reporter, Reverse Beacon Network (RBN), WSPRnet, and DX Clusters to display where DXpedition signals are being received in near real time. Rather than presenting reports as individual spots or entries in a cluster feed, the system plots activity geographically, providing operators with a broader view of how a DXpedition signal is propagating around the world.

DXpeditions often generate thousands of reception reports across multiple bands and continents. While traditional spotting networks remain invaluable, they can make it difficult to quickly understand the overall propagation picture. The new view aims to address this by transforming individual reports into a visual representation of global activity.

Operators can use the feature to identify which regions are hearing a DXpedition, observe changes in propagation throughout the day, and compare activity across different bands. Filters are available for both band selection and time range, allowing users to focus on current conditions or review activity over longer periods.

The feature is designed to complement existing spotting tools rather than replace them. By visualizing reception reports geographically, it becomes easier to identify developing openings, regional coverage patterns, and changes in propagation that may not be immediately apparent from spot data alone.

The DXpeditions View is available immediately and can be accessed from the Maps section of DXLook. For operators interested in learning more about how the feature works, a detailed guide is available on the DXLook blog.

DXLook is a free amateur radio platform that aggregates live data from multiple sources including PSK Reporter, WSPRnet, Reverse Beacon Network, DX Clusters, APRS, POTA, and SOTA. The platform was recently featured in the May 2026 issue of QST magazine.

Signals Without Borders

2026-05-21T00:00:00Z

By Michael Kalter (W8CI) Xenia, Ohio

Hamvention 2026 drew a world of kindred spirits to the Greene County Fairgrounds — and reminded us that radio waves have always been humanity's most quietly miraculous language.

At a Glance

Attendees: 37,924
Countries represented: 43+
Volunteers: 600+

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.

Hamvention 2027 will be held May 21–23 in Xenia, Ohio. Organized by the Dayton Amateur Radio Association (DARA). Official 2026 attendance figures pending final count. All other facts and figures drawn from ARRL, WDTN, Radio Club of America, and Greene County CVB reporting.

ARISS Prepares for Lunar Based Amateur Radio Communications

2026-05-17T00:00:00Z

During their Saturday Hamvention forum presentation, ARISS: Celebrating 25 Years on ISS and Pioneering New Spaceflight Opportunities for Hams and Youth, ARISS announced the formation of Amateur Radio Exploration (AREx) and their relationship with NASA that could potentially put an amateur radio presence on the Moon as part of future Lunar missions. AREx is a joint consortium between AMSAT and ARISS.

While nothing is set in stone at this stage, ARISS did speculate on the type of radio setup that could empower amateur radio operators to communicate via the Moon:

A project titled CAVIAR: Communications, Audio, Video, and imaging using Amateur Radio
Cameras for earth, moon, and vehicle imaging
Voice, digital, and video supported
10GHz and 5GHz links supported by ground station network
Scalable: change power output and supply for mission profile

MacOS App Transceive 1.4 for AllStarLink Released

2026-05-12T00:00:00Z

The following is an update from Georges (WH6AZ) announcing the release of Transceive version 1.4, a MacOS app that brings AllStarLink to Mac users.

This release includes several meaningful improvements, with a focus on long-term stability and hardware support.

Here’s what’s changed:

New: Universal binary (native support for Apple Silicon and Intel). This is a significant milestone. Native Apple Silicon support improves efficiency while ensuring the app remains stable and maintainable on future macOS versions.
New: Reorder nodes with simple drag and drop
New: Add a memo to a node entry
Fix: DNS lookup issues when nodes use non-standard ports
Update: Authentication updated for AllStar public access
Improvement: More reliable node reachability indicators (green/red status updates more consistently, with less need to refresh)

Editor's Note:

Keep an eye out for WH6AZ's upcoming app, Radio Messenger, which aims to bring a modern messaging feel to amateur Radio.

The approach here is pragmatic. RF delivery is always the priority, but internet delivery can serve as a fallback. If a message doesn’t get through, it can be held briefly and delivered later via push notifications.

The goal isn’t to replace radio with the internet, just to make the experience less brittle.

Rhizomatica Releases Mercury, a Fully Open-Source Modem for Digital on HF

2026-05-08T00:00:00Z

The following is a press release from Rhizomatica:

May 2026 — Rhizomatica is pleased to officially launch Mercury, a completely open-source Digital Radio OFDM protocol for HF broadcast and peer-to-peer ARQ connections with compatible TCP interfaces, built for reliable store-and-forward email and file transfer over HF radio links. Mercury is the newest element of the HERMES software suite, actively developed by Rhizomatica since 2017, with generous funding from ARDC and others.

Mercury is written in C, released under a GPL-3.0 license, and features a modular architecture with per-direction mode selection, hybrid SNR + delivery feedback-based gear-shifting, split control/data channel design, and uses field-proven FreeDV digital data modes, with each mode kept resident in a pool, eliminating codec re-initialization overhead. Pre-built binaries are available for Windows and Debian operating systems and Mercury is suitable for use with most HF transceivers and completely compliant for amateur use.

In early tests, compared to the commercial alternative, Mercury has performed well and is nearly at parity in optimal SNR conditions and outperforms the alternative in poor SNR conditions.

Not only has Rhizomatica developed a fully open-source software modem, they have done so to empower communities in need of their own communication infrastructure. We are proud to have supported Rhizomatica in this work, and very excited to see it now available to the amateur community and others around the world using HF for critical communication. —Rosy Schechter (KJ7RYV), Executive Director of ARDC.

I am very pleased to see Rhizomatica using the FreeDV data modes combined with their own custom ARQ protocol to send data over low SNR HF channels. It is great to see Rhizomatica embracing those waveforms, and spreading the use of open source in HF Data. —David Rowe (VK5DGR), inventor of Codec 2 and FreeDV.
