The Communicator: January - February 2026

The Communicator First Issue of 2026

Happy New Year! This first issue of 2026 spans 110 pages and offers a comprehensive exploration of amateur radio. Readers will find a diverse mix of content, including technical projects, the latest operating news, and engaging historical perspectives relevant to the amateur radio community.

Historical and Informative Features

Readers will find historical profiles of notable figures in radio, this time including Edouard Branly, inventor of the coherer, and the fateful and communications-stricken flight of Amelia Earhart. The Silent Revolution: The future of RF is in light, is an overview of transceivers using light rather than wires, promising  less noise and terrific bandwidth. You will find tutorials on a variety of relevant subjects including HF digital modes such as FT8 and JS8Call, suggestions for contest logging software, and tips for successful portable operations.

Technical Articles

Several articles in this issue delve into practical projects and technical experimentation. Topics covered include encrypted communications in amateur radio, antenna construction and tuning, including the revolutionary Challenger+, low-power (QRP) operating strategies, free access to online software-defined radio receivers, and modifications to homebrew equipment. Additional articles address emergency communications preparedness, recent regulatory changes affecting Canadian amateurs, and reviews of new ham radio products and books.

Regular Sections

The issue includes our regular informative columnists, providing valuable information for operators.  They include feature propagation forecasts, updates on satellite and digital modes, reports on VHF/UHF activity, summaries of recent contests and on-air events, and even a ‘snow muffin’ recipe for Winter Field Day.

Feature Article: Embracing Versatility in Amateur Radio

An opinion piece reflected by the cover: “Are you an Amateur Radio chameleon?” (p. 102), employs the chameleon as a metaphor for versatility in the hobby. Drawing on the Senegalese proverb, “The chameleon changes colour to match the earth, the earth doesn’t change colour to match the chameleon,” the article gently critiques operators who specialize exclusively in one aspect of amateur radio—whether chasing DX on HF, focusing on VHF repeaters, contesting year-round, or limiting activity to digital modes like FT8.

While acknowledging that specialization can foster deep expertise, the article contends that remaining in a single niche may restrict personal growth and diminish the enjoyment of amateur radio. Instead, it celebrates those who adapt fluidly, moving between CW, SSB, digital modes, satellite work, QRP portable activations, microwave experimentation, public service events, and homebrewing. These “chameleons,” the article suggests, find greater fulfillment and contribute more broadly to the amateur radio community.

It concludes with an invitation for readers to share their own stories of adaptation and discovery by emailing communicator@ve7sar.net.

The New Year's Ham Baby

Midnight struck! The calendar flipped,

A brand-new baby boy born fully equipped. 

But this was no ordinary, cooing tyke, 

He burst out screaming... "CQ! Q-R-Z! gimme a mic!"

His parents, both veteran 2-letter hams, 

were thrilled—not only by baby, but the accurate count on his radiograms. 

His first sound was: "dah dit dah dit, dah dah dit dah", a properly spaced CQ, 

A perfect fist, spectacular for a ham just so new.

Mr. Jones, the neighbor wasn't as happy. 

Just what I need, another ham next door like his mama and pappy. 

They named him "Kenwood", a name everyone knew, 

but in phonetics, baby confused quite a few. 

They bypassed the rattle, the blanket, and ball, 

‘cause he only wanted a transceiver with a nice waterfall. 

He skipped "goo-goo" for Q-codes instead: 

"My QTH is my bedroom!" is what he often said. 

And change me often when I get wet… 

I don’t want to risk the high voltage when I’m on a QSO in bed.

One day, they found him, in a corner on the floor, 

He'd built a QRP rig they couldn’t ignore. 

He keyed up on twenty, it was truly a feat, 

Sending: "Happy New Year!!" it sounded so sweet.

The FCC called, "Is that your harmonic on the air?" 

His dad just laughed, "No, sir, that’s my son you hear there. 

"He's only seven weeks old, and his signal's 5-9-9" 

The New Year's Ham Baby? He’s doing just fine!

Festive Callsigns PH25XMAS and PH26HNY Return to the HF Bands

 

Celebrating 5 Years of Holiday Spirit on the Air

Now with an AI-Powered Award System!

As the Christmas season approaches, radio amateurs across the world can once again look forward to hearing the cheerful special callsigns PH25XMAS and PH26HNY on the HF bands. These stations will be active during the Christmas holidays and the first week of January 2026, sharing goodwill and season’s greetings over the airwaves.

This year marks the first lustrum (5th anniversary) of the festive XMAS and HNY event calls. To mark the occasion, the organizing team has developed an all-new automated award platform — a creative blend of amateur radio, Python programming, and artificial intelligence. It is called SAVS (Special Award Validation System).

The system will be operational, starting the 6^th of December 2025. Until then a page is showing a count-down timer to the first date of operation and first opportunity to check the award eligibility.

A Fully Automated Award System:  SAVS

Participants who have made QSOs with PH##XMAS and/or PH##HNY stations between 2021 and 2026 can check whether they qualify for a commemorative certificate.

The new award system at 👉 https://award.pa3efr.nl works like this:

• The platform automatically searches remote and local ADIF logs (PH21XMAS–PH26HNY).
• Operators whose callsigns appear three or more times in the logbooks across the past four years and this year are eligible for an award.
• After entering your callsign on the Entry Page, the system validates your QSOs, displays the results, and — if qualified — instantly generates a personalized PDF certificate for download.

Behind the scenes, a Python Flask server performs the validation, integrates with QRZ.com for data verification, and generates your award PDF with just one click.

Open Source and AI-Assisted

The entire system was created with the help of AI tools and is released as a fully open-source project on GitHub: https://github.com/PA3EFR/SAVS_XMAS_HNY

Every element — from log validation to PDF generation — runs autonomously, demonstrating how classic ham radio activity can harmoniously combine with modern coding and machine learning.

Join the Celebration

So this festive season, when you hear “CQ from PH25XMAS” or “CQ from PH26HNY”, don’t hesitate to call back!

You might not only exchange warm holiday greetings, but also earn yourself a special place in the logs — and a beautiful award to commemorate it.

Pile-Up Control System

PUCS: Take control of the pile-up!

by SANDER PD9HIX and ERWIN PA3EFR VAN DER HAAR

Every special event station (SES) operator knows the thrill — and the chaos — of a true pile-up. The excitement of dozens of stations calling you simultaneously can quickly turn into frustration when QRM, doubles, and missed calls clutter the frequency. Wouldn’t it be great if there were a way to bring order to that chaos without losing the fun of real-time operating?

Enter PUCS, the Pile-Up Control System, a fully open-source, web-based platform designed by and for radio amateurs. Born from the ingenuity of the Radio Scouting Fellowship PA3EFR/J, PUCS elegantly blends traditional ham ingenuity with modern AI-assisted software development. The result is a modular, flexible system that any club or individual can tailor to their own operating style — from large-scale SES activities to small club field days.

PUCS can be seen operational at pucs.pa3efr.nl

From Normandy to the Netherlands

The idea for PUCS was sparked during an SES operation on the beaches of Normandy, where operators of TM80DDAY overheard multiple Australian colleagues discussing a private sign-up system for QSOs. Intrigued but unable to obtain the software, Erwin PA3EFR and his team decided to build their own version — and then share it freely with the world. With the help of AI tools and some Python wizard Barry, PC1K, PUCS was born. It was much later when Erwin decided to develop PUCS within his own environment.

Today, PUCS is freely available, fully documented, and open to anyone willing to experiment. It’s more than just software — it’s an invitation to collaborate, learn, and contribute to a smarter way of managing pile-ups.

What Makes PUCS Unique

At its heart, PUCS is a distributed system consisting of two parts:

• Frontend (commercial hosting): This is the public entry point where operators register their callsigns to join the queue. Think of it as a digital “waiting room” — transparent, fair, and visible to everyone.  
• Backend (local PC): Here’s where the magic happens. The backend checks QRZ.com logbooks every minute, automatically removes callsigns that have already been worked, and provides an admin dashboard to manage the queue, export logs, and adjust settings on the fly.

The system uses Python’s Flask framework, SQLite databases, and SocketIO for real-time updates — all standard, well-documented technologies familiar to many technically minded amateurs. It’s simple enough for a club to host on a modest PC, yet robust enough to handle large SES events.

Open Source, Open Spirit

PUCS is more than a tool — it’s a philosophy. The creators explicitly invite others to modify, enhance, and restyle the system to their own preferences. Whether you want to change the interface colors, add logging features, integrate digital modes, or redesign the operator dashboard, the code is yours to explore. There’s no hidden agenda, no locked components — just open code and open collaboration.
All scripts, examples, and documentation are available on GitHub:

https://github.com/PA3EFR/PUCS

Why You Should Try It

PUCS is a perfect project for your club’s next technical workshop. It offers practical lessons in networking, APIs, databases, and web hosting — all wrapped around a real amateur radio application. 
Beyond that, it promotes fairness in pile-ups, gives weaker stations a chance to make contact, and even allows SWLs to log their participation.

So fire up your soldering iron if you must, but this time, your “kit” is made of code.
Download PUCS, make it your own, and bring calm to your next pile-up.

As Erwin, PA3EFR, says: “Ask AI as your friend for support — and enjoy your own moments of challenge!” On behalf of the Radio Scouting Fellowship PA3EFR/J we look forward to see you on our PUCS screens at a next special event occasion.
