#4 - Amateur Radio News and Announcements (14 July 2026)

 In this issue of Amateur Radio News and Announcements:


1.  No-SDR: A New Open Source Multi-User WebSDR for RTL-SDR:  

No SDR hardware on your desk? No problem. Multi-user web receiver with real-time waterfall, stereo FM, and digital mode decoding — all served from Go back end to your browser.  

no-sdr turns cheap RTL-SDR USB dongles into a full-featured web-based radio receiver. Multiple users connect through their browser and independently tune, demodulate, and listen to signals — all sharing the same hardware. No plugins, no installs, just open a URL.

Think of it as your own private, open WebSDR that you can run at your home pc or on a docker container (compose). Works in Raspberry Pi too.

This project aims High Fidelity, weak signals processing, near lossless quality, low bandwidth consumption and aims every feature to be run also on arm architecture (RPi/MAC). For x86 four binaries are included and you CPU capability level is detected on container start, processors with streaming extensions (SSE/AVX etc.) have superior performance and each client consumes less CPU cycles. All of this open, no closed source.


2.  G4NSJ - What happened to amateur radio? Where is everyone? Where is the ionosphere?

What happened to amateur radio? Where is everyone? Where is the ionosphere? Band conditions have been awful, 40 meters is dead. What's all this EQ business about? Why pump up the bass on SSB?  Why run a kilowatt when you have a rubbish antenna? This explains a lot...

G4NSJ examines the decline in activity across various amateur radio bands and repeaters. Discussion focuses on changing communication practices, including the use of high power and audio processing on side-band, while contrasting current experiences with techniques from the past.

3.  Tune into the DMR-ZA Net this evening at 19h30 SAST

To my big surprise the article that I wrote about the DMR-Net available HERE is currently one of the most popular posts on the Blog.  It would appear that there is a great interest in DMR in South Africa. 

Herewith a list of different equipment / apps and images that cross transmit / receive the DMR-ZA Net on a Tuesday evening. (Click on images for larger view.)

1.  ZS1I 49355 AllStar Hub Network which incorporates Echolink. (ZS1I-R)

2.  DMR / DVSwitch /AllStar Bridge (TG 65522)

3.  ZS1I MMDVM Digital Repeater (TG 65522)

4.  145.550 Mhz Analogue Simplex RF Link Mossel Bay area.

9.   Many Analog-Repeaters and Links are connected to the ZS1I Hub Network on a daily basis.  Some of these analogue repeaters will be connected to the ZS1I Hub Network on a Tuesday evening and they might also be linked to other repeaters country- and world wide.  So why not link up with your local analogue repeater.  You might just be able to connect to the DMR-ZA Net on a Tuesday evening at 19h30 SAST. 


 4.  Increased Cape Traffic Brings Maritime Security in Focus

The article is available HERE.

Now out of an amateur radio point of view the question arises, with increased maritime traffic around the Cape of Good Hope, what will happen in event of a maritime disaster?  The Western Cape coastal area is well know for many maritime disasters in the past and you will find many shipwrecks around the coastline of South Africa.  With the sinking of the Oseanos cruise ship great challenges were forthcoming in rescuing passengers from the ship.  Radio communications is still today of the utmost importance during any disaster.  

Here are some information regarding South African Maritime Mobile Net (Amateur Radio Maritime Net) and Cape Town Radio (South Africa's primary maritime radio coastal station).

As an amateur radio operator living in Mossel Bay (coastal town) the increase in Maritime traffic and the focus on Maritime security should not be ignored. We as coastal radio amateurs must be ready for any eventuality that might happen.

6.  Amateur Radio in Men’s Sheds: Community Outreach Through Science, Technology and Connection

Amateur radio offers Men’s Sheds a powerful new way to connect with members who may not be drawn to traditional woodworking, metalworking or workshop activities. For many people, the attraction is technology, science, communications, electronics, weather, computers, space, emergency communications and lifelong learning. An amateur radio program gives these members a place to belong, contribute and keep learning, while still delivering the core Men’s Shed goals of social connection, purpose, well-being and practical community benefit.

The community benefits are significant. Amateur radio can help reduce social isolation, encourage participation, support mental health, build confidence and provide opportunities for skills transfer between generations. It also helps strengthen community resilience by developing local communications knowledge and emergency preparedness. With partnerships involving amateur radio clubs, schools, Scouts, libraries, universities, STEM groups and emergency service organizations, a Men’s Shed radio program can become a genuine community outreach hub. 

Comment: Well done Australia!!  I had the great privilege to visit a Men's Shed in Toowoomba, Australia about three years ago.  What an experience for a South African Old Timer.  A pity that there is no Men's Sheds in South Africa.  Information on the Toowoomba Men's Shed available HERE.

The decline in Amateur Radio during winter is neutralized by creating activity!!


Who said there is a decline in Amateur Radio during the winter months?  I said so.  Look HERE.

My OM had a saying that if a door is closed into your face, you must always find another door to open and continue with what you are doing and enjoying.  This means do not give up and you will be able to continue also in amateur radio.  So true and this saying I have been following throughout the years.  It allowed me to bounce back in life sometimes even with better results than before.

Well amateur radio activity is up here in the Mossel Bay area as well as parts of South Africa.   Let's look at some of the activity by means of illustrated images:  


Image above:  Connected nodes to the ZS1I HUB in Mossel Bay  (Click on image for larger view.)

Image Above:  Bubble Chart of stations connected to the HUB yesterday afternoon.  (Click on image for larger view.

1.  ZS1I HUB Network Activity:  I will let the images speak for themself.  The HUB is alive and active on a daily basis with stations frequently heard also via all the cross-links and connected nodes and repeaters.  A few overseas stations were also heard on the ZS1I HUB Network.  I do not take any credit for this as the network consists of many participating entities.  Great to hear all the activity taking place.

 Image: Some "useless" information? (Click on image for larger view.)

2.  ZS1I  Amateur Radio Projects / Activities Blog:  This blog is was created in April 2026 and is already being visited by many viewers on a daily basis.  Hopefully the blog is not only my place were I keep some back-up information but also a medium where young and old can learn something.  I am not a person chasing records or wanting any attention in amateur radio.  I am to old for that nonsense.  The Blog for me is like a amateur radio "diary".  Many article might also be bored and not of interest to others.  None the less thank you to all the visitors for visiting the ZS1I Blog.   I hope to keep up rolling articles out that might be of interest to the general amateur radio community.

3.  DMR Activity still on the increase World Wide!  - Need I say anything about the increase in the use of DMR World Wide and in South Africa?   This is great news for amateur radio operators and the future of digital radio modes.  With the cross-linking of analogue systems to digital systems nobody is left out in the cold even if you only have a analogue HT radio.  At times the ZS1I HUB Network is linked to various DMR Talk Groups which resulted in an increase in activity.  The audio is good and the linked systems work great.  Yesterday operators were heard from Germany, Australia, UK, USA, Japan on Hoseline which was cross linked to the ZS1I DMR Bridge and DMR Repeater in Mossel Bay.  And no it was all country talk groups and not the World Wide Talk Group (91).  Great conversations and activity on DMR.  I do have a few ideas and changes that I would like to make to even better the current cross linked system.   Stay tuned!!

Image:  Stations that spotted the ZS1I 40m WSPR Beacon recently,  thanks to all.  (Click on image for larger view.)

4.  40m WSPR Activity:  WSPR is a great amateur radio propagation tool.  I am amazed on how propagation changes on the 40m band from time to time.  At one stage only a few stations received the 40m ZS1I WSPR Beacon.  Then all of a sudden there was a increase in spotted stations.  I must admit that I have lots to learn about WSPR.  Sure this will come with time.  In the mean time many thanks to all who regularly spot the Mossel Bay WSPR Beacon.  More interesting developments to come relating to WSPR Beacons in the future. 

5.  ZA-Net Network Activity:  For the past few days I have connected the HUB to the ZA-Net Network up in Gauteng.  At times there were activity even from abroad.  The audio quality was good and the network is working great.  Herewith more information about the network:

2.  ET still cannot phone home!!

The article is available HERE for those who did not read it.

Transgressions and bad operating practices are still taking place on a daily basis on many of the amateur radio bands and therefor ET cannot phone home!!  Hi Hi!!  Well this is to be expected if nothing is being done to amicably solve these bad practices.   At least I feel a bit better after writing the article.   I guess the Amateur Radio Code of Conduct is not important to some radio amateurs.  However we are living in a comparatively chaotic world with increasingly less social pressure to act or think a certain way. While that freedom is certainly opening the door for plenty of free thought and fresh perspectives, it can be easy to slip into hypocrisy or self-delusion – imagining we’re one thing when we’re actually another. A code, a set of concrete standards which we can objectively understand and vocalize, not only guides us but convicts us. In a world where there’s often no one but ourselves to keep us accountable, the amateur radio code of conduct serve to keep us on track, or at the very least get us to rethink our most fundamental values.3.


3.   ZS Link Network Group yearly get together.

On 18 July 2026, it is once again time for the yearly get together of the ZS Link Network Group at Blandsdrift, Mossel Bay of Jasper ZS1WT and Natasha (LV) with their two young daughters, Larissa and Linelle.

For more information about the gathering listen on the 145.625 Mhz Aasvoelkop Repeater or visit the 625 WhatsApp Group.

On behalf of myself and the family I would like to  render my apology as I will not be able to attend the ZS Link Group gathering on the day.  This is due to another family responsibility that needs my attention.


4.  AI - The New Amateur Radio Elmer?

Yes, AI is increasingly serving as a modern "Elmer" (the traditional amateur radio term for a mentor). While AI will never replace human connection or the hands-on, practical guidance an experienced Elmers offers, it is revolutionizing the learning curve for both newcomers and veteran operators. 

Why AI Makes a Great Elmer

    • 24/7 Availability: You can ask technical questions about antenna theory, RF gain, or operating procedures at any time without waiting for a club meeting. 

    • Personalized Tutoring: AI can break down difficult concepts in multiple ways based on how you learn best, from long-form explanations to specific code snippets. 

    • Study Assistance: Systems can act as digital tutors, tracking where you struggle on practice for the RAE exams and generating targeted questions to improve your understanding. 

Where Human Elmers Still Win

    • Hands-on Help: AI cannot physically help you solder a connector, tune a beam antenna, or show you exactly how to route coax into your shack. 
    • Real-world Experience: Traditional Elmers provide nuanced, practical advice learned over decades on the air—such as how a specific radio behaves in a pile-up or local club politics. 

More detailed information:

Artificial Intelligence functions as a 24/7 technical co-pilot for amateur radio operators by instantly analyzing complex RF data, generating code for digital modes, and explaining dense radio theory. While human Elmers provide essential hands-on mentorship, AI accelerates self-directed learning and troubleshooting.

How AI Functions as a Digital Elmer

1. Accelerated Technical Troubleshooting

    • Schematic Analysis: Operators upload photos of circuit boards or wiring diagrams to identify faulty components.
    • Error Decoding: AI translates obscure error messages from software-defined radio (SDR) programs or digital mode software.
    • Component Substitution: The system suggests modern alternatives for obsolete transistors, capacitors, or vacuum tubes in vintage gear.

2. Specialized Software and Coding Support

    • Microcontroller Programming: AI generates and debugs C++ code for Arduino or Raspberry Pi projects like antenna tuners and rotators.
    • CHIRP Programming Logs: It formats large CSV files containing frequencies, offsets, and tones for bulk radio programming.
    • Automated Logging Scripts: Systems write custom scripts to parse ADIF (Amateur Data Interchange Format) files for contest logging.

3. Interactive Exam Preparation and Theory

    • Formula Breakdown: AI explains the mathematical relationships behind Ohm's Law, SWR calculations, and decibel conversions.
    • Targeted Quizzing: The system dynamically changes its questioning style based on your weak areas in RAE learning.
    • Visual Concepts: It describes spatial concepts like antenna radiation patterns, ionospheric skip zones, and polarization.

    • Lack of Safety Feedback: A chatbot cannot see if you are about to touch a charged high-voltage capacitor or improperly ground an amplifier.
    • Regulatory Nuances: AI may misinterpret local band plans, emergency traffic priorities, or specific national amateur regulations.


5.  Does the future of Amateur Radio lie in the GHZ Bands?

The future of amateur radio does not lie exclusively in the GHz bands, but these frequencies represent the fastest-growing frontier for technical innovation and experimentation within the hobby.

While traditional High Frequency (HF) bands (1.8 to 30 MHz) remain the beloved backbone for long-distance, ionospheric "rag-chewing" and DXing, the Super High Frequency (SHF) and Extremely High Frequency (EHF) bands (1 GHz to 300 GHz) are revitalizing the maker and hacker culture of ham radio. 

The role of the GHz bands in shaping the future of amateur radio is defined by specific opportunities and challenges: 

Why the GHz Bands Represent the Future of Innovation

    • Massive Available Bandwidth: Traditional HF bands are narrow and congested. In contrast, the GHz bands offer vast allocations of spectrum. This massive bandwidth allows hams to experiment with high-speed data pipelines, high-definition Digital Amateur Television (DATV), and complex digital mesh networking. 
    • Emergence of Commercial Gear: Historically, operating above 1 GHz required advanced homebrewing or repurposing military surplus gear. The release of commercial, multi-band SHF transceivers—like the Icom IC-905—has drastically lowered the barrier to entry, bringing plug-and-play microwave operation to everyday hams. 
    • High-Speed Mesh Networks: Amateur Radio Emergency Data Networks (AREDN) utilize commercial-off-the-shelf wireless hardware modified to operate on amateur 2.4 GHz and 5.8 GHz allocations. This allows hams to build independent, high-speed wireless networks for emergency communications, capable of routing video and VoIP data over large geographic areas. 
    • Cutting-Edge Space & EME Communication: Modern amateur satellites and deep-space projects increasingly rely on GHz links. Additionally, Earth-Moon-Earth (EME) or "moonbounce" communications heavily utilize the 10 GHz and 24 GHz bands, where smaller, highly-directional dish antennas can be used. 
    • Millimeter-Wave (mmWave) Experimentation: At the extreme end (47 GHz, 76 GHz, and 122 GHz), hams are adapting low-power automotive radar ICs and telecom components to break distance records, pushing the physical boundaries of atmospheric propagation. 

The Defensive Battle: "Use It or Lose It"

The greatest reason the GHz bands dominate conversations about the future of ham radio is political. Commercial telecommunications, 5G/6G cellular deployment, and satellite mega-constellations are starved for mid-band and millimeter-wave spectrum. 

Amateur radio allocations at 3.4 GHz and 5.8 GHz have already faced regulatory pressures and partial rollbacks by agencies like the FCC to clear room for mobile networks. If the amateur community does not actively populate and experiment in the GHz bands, regulatory bodies will continue to reallocate this incredibly valuable spectrum to commercial interests. 

The Verdict

The future of amateur radio is fracturing into a vibrant dual ecosystem:

    1. The Traditionalists: Will stay on HF, VHF, and UHF for long-range voice, CW (Morse code), and global weak-signal digital modes like FT8. 
    2. The Technologists: Will push into the GHz bands to merge radio frequency (RF) technology with AI, high-speed computing, and advanced networking. 

The GHz bands may not replace HF, but they are absolutely critical to keeping amateur radio relevant, cutting-edge, and legally protected for decades to come.

Change: Broadcast of Bulletins, Nets, Live Link Connections on the ZS1I AllStar HUB Network which will include National and International Broadcasts


Important:  HERE is the current schedule for Bulletins, Nets and Link Connections.  This schedule will soon change as described below.

Many might not know but I am not a monotonous type of person.  I hate when certain repetitive or stale amateur radio activities, nets, chats etc. takes place year in and year out on the same old trend.  To put it plainly - It is mind-numbing !!  Therefor I enjoy making changes on a regular interval to not lose interest or have to listen to useless information over and over.

I had been thinking and that can be rather dangerous.  Well I came up with a new method of broadcasting amateur radio news content.  I am busy setting up a new server that will be used for broadcasting amateur radio news on demand or at a certain time.  I am still working on some detail to achieve a great outcome using AllStarLink, Echolink and DMR.  This setup will run parallel to the current ZS1I Hub Network which will only be used for Nets and QSO's.   Listeners will be able to connect to the News Server and listen to a wide variety of content which will also include podcasts.  Once I have the server operational a final implementation date will be set.

The change will result in the fact that the Sunday morning bulletin schedule will change dramatically.  I envisage that only the two SARL Bulletins will be transmitted at 08h15 and 08h30 SAST on the ZS1I Hub Network.  NO other bulletin or news broadcasts will be transmitted on the ZS1I Hub Network unless prior approval is granted for such broadcasts.

The idea I have is for operators to connect to the dedicated news server either with AllStar, Echolink or DMR to listen to the provided content.  I will provide and list (index) of content that you can listen to and on what day and time.  A nice feature would be a on demand automated digital stream that will stream content on request, maybe something for the future but for the time being, I will use the scheduled method. 

Why not broadcast Amateur Radio News Bulletins on the ZS1I Hub Network anymore?  It is quite easy to explain.

1.   The rapid system expansion of the ZS1I Hub Network resulted in a heavy workload on the equipment of the ZS1I Hub Network  and the administrators of other networks in South Africa.  The SC Network is currently one of the largest networks in South Africa and carries heavy traffic at times.  Control, supervision and maintenance of the network repeaters, nodes, bridges etc. at all times is of the utmost importance to ensure the smooth functioning of the network.  The network consists of many other local and worldwide stations which is linked to the ZS1I Hub Network.  Administrators have to take the rapid expansion, size and workload on all the system into consideration.

2.  The ZS1I Hub Network is a private operated network and is not affiliated to any club, group or organization. The ZS1I Hub Network owner maintain good relations with all clubs, organizations and fellow radio amateurs,  world wide.   The ZS1I Hub owner therefor has no obligation to any club, group or organization when it comes to the broadcast of local amateur radio news bulletins.  

3.  Many national and international amateur radio news bulletins are nowadays automated.  This means that the ZS1I Hub Network System (computer) automatically downloads the audio file from a web-site, cut it up into time slots and then automatically plays it on the network at given time. This is surely the way to go and does the ZS1I Hub Network make use of this helpful AllStar function.  No compiling, editing and live reading of a bulletin on the air.  The  automation of national and international is the preferred method to transmit amateur radio news bulletins as it works great and does not result in a heavy workload on especially RF systems, equipment on the network and administrators.

4.  Many large VOIP and RF Radio Networks has taken the decision not to broadcast any amateur radio news bulletins on their networks.  There are many reasons for this decision.  Some of these networks literally have 100's of systems including RF Repeaters connected together and it makes sense to not broadcast any club bulletins on such networks as a local club bulletin is meant for that specific club members and not for world wide broadcasting.  The ZS1I Hub  Network has therefor also taken the decision not to broadcast local club bulletins over the large network.

5.  Restructuring of the network.  Yes the dreaded word called restructuring, many hate to hear.  Unfortunately we do not live in the stone age and we as radio amateurs need to stay informed of the latest technology and experimenting.  Future changes to the ZS1I Hub Network will be made and some will love it others will hate it.  Amateur Radio means to regularly engage in the activity, developing skills, experiment, learning new things, and finding enjoyment in the process.  Sometimes we need to restructure the network, if not we will stagnate and not move forward with the times.  

The above surely explain the reasons why I will discontinue the broadcasting of local amateur radio news bulletins on the ZS1I Hub Network and create a free standing Amateur Radio News Server as explained above.

Finally:  As indicated the implementation date and how to use the server will be announced in a future posting when the all New  ZS1I Amateur Radio News Server will be operational.  Until then the current method will be still available. Test transmissions might be heard from time to time on the ZS1I Hub Network.

1.  First ever Moon-Bounce QSO between Netherlands and South Africa on the 24 Ghz Band

 

"On Sunday 14-06-2026 the first ever 24 GHz EME contact was made with the African continent. John ZS6JON and Hans PE1CKK made a two way contact via the moon. This QSO had a long preparation, John contacted Hans a year ago to find out if Hans had some parts to build a 24GHz setup. Parts are very hard to find in South Africa. Hans had a better solution and shipped his second station to SA together with a small beacon to check the installed setup. After a lot of mail and chatting between the two radio amateurs, John had the system up and running last Sunday. Right at the first TX cycle he had a decode and they achieved the  contact (QSO). The setup will stay for some time in SA to allow John to make more contacts via skeds. Working equipment: 1.8m offset dish, wavelab transverter, RW1127 twt 25W and DU3T lna. "

Congratulations to John and Hans on the first ever QSO between South Africa and the Netherlands on 24 Ghz band. 

2.  Earthquakes in Venezuela prompt request for clear emergency frequency

All radio amateurs are being asked to keep 7.135 MHz in the 40-metre band clear for emergency communications in the wake of back-to-back earthquakes that struck Venezuela on Wednesday 24 June. The two quakes, measured by the US Geological Survey at magnitude 7,2 and 7,5 respectively, occurred just one minute apart and caused extensive damage across the South American country, including the capital city of Caracas. As of Thursday morning, government officials were reporting at least 164 deaths, nearly 1 000 injuries and hundreds of people missing. These tolls are expected to rise as rescue/recovery operations continue. More information in the SARL Hamnet report during Amateur Radio Today at 10:00 CAT. 

3.  SARL Newbie QSO Party Saturday, July 4⋅11:00am – 4:00pm

All the new radio amateurs from the May RAE are invited to participate in the first leg of the SARL Newbie QSO Party from 11:00 to 16:00 UTC on Saturday 4 July. It is a phone only contest on 40 and 20 metres. The exchange is a RS report, your four-character grid square e.g. JF95 and a phonetic letter indicating how long you have been licenced. The QSO scoring also depends on how long you have been licenced. Submit your log sheet by 21:59 UTC on Saturday 18 July to zr3vdk@outlook.com and zr3pa@outlook.com.

Amateur Radio in the age of AI

Video:  Dr. Paris Buttfield-Addison (VK7SYN) discusses "Artificial Intelligence & Machine Learning in Amateur Radio," what AI actually is & demonstrates the potential for AI to enhance amateur radio.  -  Ham Radio DX 
Amateur Radio in the Age of AI 
Artificial intelligence is revolutionizing amateur radio by automating routine tasks, enhancing signal processing, and optimizing contest strategies. Far from rendering the hobby obsolete, AI acts as a powerful operating assistant—improving noise filtering, expanding accessibility for operators with disabilities, and advancing global spectrum experimentation. 
Key Applications of AI in Ham Radio
  • Signal Processing & Noise Reduction: AI algorithms are increasingly integrated into software-defined radios (SDRs) and digital signal processors (DSP). They can intelligently filter out background noise, isolate weak signals in harsh atmospheric conditions, and enhance audio clarity. 
  • Contest Strategy & Logging: AI analyzes massive datasets from the DX Cluster to provide real-time recommendations on rare stations, predict optimal band frequencies, and optimize your overall score during major contesting events. 
  • Accessibility & Voice Control: Machine learning models assist operators with speech impairments or visual limitations to participate in digital modes (like FT8) through automated text-to-speech, voice control, and digitized voice generation. 
  • Propagation Forecasting: AI systems process historical and real-time space weather, solar flux index (SFI), and geomagnetic data to generate highly accurate HF (High Frequency) propagation predictions.
What AI Cannot Replace
While AI can help you hunt down contacts or log QSOs, the core of amateur radio remains human. The technology cannot replicate the thrill of building physical antennas, improvising off-grid communications during emergencies, or the tactile feel of tuning a radio. The regulatory framework for amateur licensing and transmitting—managed globally by bodies like the ITU—still requires a licensed human operator at the helm. 
Now lets look a little deeper into this sometimes controversial topic. 
The application of artificial intelligence and machine learning in amateur radio has transitioned from conceptual experimentation into real-world software tool-chains and radio hardware. AI operates as a powerful algorithmic layer that interfaces with the physical environment, processing massive amounts of telemetry data and raw RF (Radio Frequency) audio streams. 
The primary technical areas where AI is creating the most significant impact include advanced digital signal processing, dynamic ionospheric modeling, and cognitive station automation. 

1. Neural Networks & Advanced Digital Signal Processing (DSP)
Traditional DSP relies on hard-coded mathematical rules (like fixed Bandpass or Notch filters) to clean up signals. AI replaces or augments this with recurrent neural networks (RNNs) and adaptive filters that train on millions of noisy audio samples. 
  • Intelligent Noise Isolation: AI filters can dynamically distinguish between human voice, Morse code (CW), and ambient localized interference—such as EMI from solar panel inverters, power grids, or switching power supplies. It subtracts the noise in real time, making borderline unreadable signals intelligible. 
  • Automatic Signal Classification: Using low-power hardware (such as a Raspberry Pi paired with an RTL-SDR dongle), AI algorithms use open-source pipelines to instantly identify, classify, and isolate specific modulation types (e.g., APRS, FT8, FM, or satellite beacons) across wide swaths of the radio spectrum. 
2. Predictive Propagation and "Big Data" Ionospheric Modeling
Predicting whether an HF (High Frequency) signal will bounce off the ionosphere to reach a specific continent has historically relied on static monthly median models like VOACAP. AI shifts this to real-time, fluid forecasting: 
  • Telemetry Integration: Machine learning algorithms continuously ingest live data streams, including Solar Flux Index (SFI), geomagnetic activity (K-index, A-index), coronal mass ejection alerts, and planetary ionosonde readouts. 
  • Crowdsourced Spot Mapping: Modern AI architectures collect hundreds of thousands of daily data points from networks like the Reverse Beacon Network (RBN) and DX clusters. By analyzing the paths where signals are actually getting through right now, the AI builds deep-learning models to map out precise, real-time RF "micro-openings" on the bands. 
3. Smart Contesting, Automated Logging, and Strategy
During radio contesting—where the goal is to make as many rapid-fire contacts as possible—AI functions as a digital co-pilot. 
  • Predictive Spotting & Hunting: AI systems analyze cluster feeds to prioritize rare DX stations based on your station's historical capabilities, antenna trajectory, and local terrain limitations. It advises when to switch bands or call a specific frequency before the band opening disappears. 
  • Automated Call Translation: In weak-signal scenarios or heavy pileups, AI assists in audio decoding. Generative audio tools can infill missing packets of voice transmissions, predicting a call sign's broken suffix or prefix based on global license databases and phonetic speech patterns. 
4. Accessibility and Cognitive Radio Control
AI lowers the physical barriers to entry for disabled, aging, or speech-impaired operators, ensuring inclusivity in the amateur community. 
  • Speech and Language Translation: Real-time translation models allow operators of different nationalities to converse smoothly via voice. For operators with localized speech impairments, AI can map inconsistent vocal inputs into synthesized, digitized voices that cleanly trigger SSB (Single Side-band) transmitters. 
  • No-Code CW Assistants: Machine learning toolsets are being developed to interpret high-speed, poorly spaced, or drifting manual Morse code ("fists"). This translates raw audio into readable text on a screen without requiring the operator to master the code by ear.

From the beginning, amateur radio has connected people with reliable information and companionship, including in the most difficult moments during emergencies or disasters.

In this new era, AI must remain a tool to serve that mission: helping radio amateurs to assist more people, in more languages; never replacing the editorial responsibility for which communities rely on amateur radio stations during disasters.

World Radio Day, celebrated yearly on 13 February, honours the medium’s unique power to inform, connect and accompany people everywhere. 
The latest annual theme reminds us:  
AI is a tool, not a voice.”
We need to continue to preserve the Amateur Radio bands / airwaves as a valuable resource that enables this unique medium to thrive.

Ultimately, radio’s future depends on using AI to reaffirm and strengthen the human values that define the medium.
