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.

Update: What progress is being made with the ZS1I - 6 Meter CW Beacon in the Southern Cape Area?

Well I have been asking this question to myself several times since this project was launched.  The project has not been shelved although due to other "gremlins" in the shack the priority and importance was down-scaled a few times until other breakages were fixed.  I am sure that you will agree with me that the 6m Band in the middle of Winter is fairly dead and the priority is on the low side.  Just to re-cap here is the links to the project for those that might have missed it.

1.  Building Low Budget Antennas - DIY Delta Loop Antenna for the 6 Meter Band ( 50 - 54 Mhz)

2.  Building Low Budget Antennas - DIY Moxon Antenna for the 6 Meter Band (50 Mhz)

3.  The ZS1I - 6 Meter Magic Band Project in the Southern Cape Area of South Africa. (Part 1)

4.  Heads Up - Here comes the Next Generation Amateur Radio Beacon (s) for the Southern Cape!! (Part 2)

5.  Update: Next Generation Amateur Radio Beacon (s) for the Southern Cape!! (Part 3) 

Now when I found the time I worked on the 6 Meter CW Beacon.  I also ordered a few parts that I am waiting for to continue the project.  The image below depict the work done so far on the beacon.  There is not many things left to do, that's if the "gremlins" stay away from the work-bench.

I will keep those interested updated about the project and when the beacon is switched on and on the air.  Updates to follow!

What is happening to Amateur Radio in South Africa and will ET be able to phone home ?

Image:  ET phones home correctly by using good operating procedures  (Click on image for larger view.) 

The title question can be interpreted in two ways.  No need for me to explain.  I am sure that there are many South African Radio Amateurs that love the hobby and some started in the hobby while they were still kids.  On occasion I called the hobby an obsession which is a bit over the top.  But that is how I feel about the best and most versatile hobby in the World.   

However  ......  there are a few things that needs to be rectified or looked at, that is not in line with the Amateur Radio Code of Conduct or that transgress the Radio Act and or Radio Regulations.  I on many occasions have said that I am not a "policeman" and has no authority to take any action to rectify any transgressions.  I can however voice my dissatisfaction about a few transgressions as the amateur radio hobby is / should be a self regulating hobby without the need for the authorities to intervene.  

The incidents / transgressions that I am going to mention here is really damaging the image of the hobby and I am sure that this is not what we want to observe and hear about amateur radio.  Be as it may I need to get the following off my chest:

• Blatant transgression of call signs on the air  -  Have you heard the following:  "1I good afternoon."  1I is not a call sign.  The correct use of the call sign must be "ZS1I good afternoon".  The abbreviation of a call sign is a transgression of the radio regulations.
• Another transgression is when an operator calls in as "Tobie from Put-Sonder-Water, good afternoon".  Where is the call sign and who is Tobie ..... a pirate?  Even if you know the voice and the person why does he not provide his call sign when he break into / join a conversation.  At least everybody on the air will from the on-set know who Tobie is!
• The following example in my opinion is rude and I will not even try to join the conversation.  The following happens on many bands.  Right off the bat is HF.  Two friends are chatting and a third and fourth wants to join but the two operators leave no gap for anybody to join.  They just carry on talking.  Yes I know about conditions etc. but this also happens on the VHF / UHF bands and repeaters.  This is not in line with the Amateur Radio Code of Conduct.
• Since when is a cellphone call more important than an amateur radio conversation.  Have your heard the following:   "Just stand by I have a phone call."  Half an hour later the receiver of the phone call returns and expect to chat further.   This happens many times.  Switch you phone off or do not join a conversation if you expect a call on the cellphone.  Why can you not later return the cellphone call after you ended the QSO?  I have been left in the cold on many occasions and do not "come back" when the "offender" returns.  In my opinion this is out-rite rude conduct.
• "Kerchunking ..... Kerchunking!!   Need I say anything more about kerchunking a repeater?  What is so difficult to say "ZS1I testing / monitoring the 145.775 Mhz repeater"?   On several occasions I have heard somebody responding to a Kerchunker,  friendly reminding him to provide a call sign but not providing his own call sign on the air.
• Amateur Radio has a few musicians on the air as well.  They love to play courtesy, sirens and other tones on the air.  Sir / Madam your tones are a nuisance and serve no purpose at all.  You can still use your DTMF tones by setting it up not to be heard on-air via a node etc.  Nowadays there is no need to hear any tones on the air.  There are other ways to do it correctly.
• CB slang and jargon!!  I also started off in CB many years ago when CB radio just started to become popular.  Please refrain from using CB slang or jargon in Amateur Radio.   I hear many operators in amateur radio talking the talk of CB.  If you want to use slang or jargon use your CB radio for that purpose.
• Another irritating practice is when a station is talking or busy to hand over to another station and someone makes a comment over a person or in between rounds without providing his call-sign.   Why can this person not wait until it is his / her time (over) to speak.  This practice in my eyes is causing deliberate interference on the air.  Is this a practice that was used by rogue CB operators?  

I have only mentioned a few irritating transgressions which also contravene the Amateur Radio Code of Conduct.  I am sure that you can think and add more ugly "habits" that is not mentioned in this article.

Ask any older radio amateur that has been a radio amateur for many years and he or she will be able to confirm that this is not the way to operate an amateur radio station.  Yes, some of the older operators are also at fault and I do not point finger to any generation in this regard.

If the above transgressions / ugly trends continues it will damage the image of amateur radio and also chase many away from this wonderful hobby which we cannot afford under any circumstances.  

The South African Radio League Web Site provides value information on Ethics and Operating Procedure for the Radio-Amateur made available by the IARU,  Click  HERE to view.

Good operating procedures should and must always be our first priority in amateur radio otherwise ET will not be able to phone home!  👌😢

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.

Great to see so much activity on the 40m WSPR Beacon section of the band.  Quite a few new stations were observed this past week. 

5.  Solar Cycle 25 Expectations in 2026 and beyond - by Carl K9LA

Carl K9LA recently gave a presentation to the Madison DX club about what propagation conditions would be like in 2026.  We are on the way down the peak of the sunspot cycle but there will still be plenty of openings for a while yet.  See video for more information. 

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.

Comparison: Traditional vs. AI-Enhanced Radio Operation

Feature	Traditional Amateur Radio	AI-Enhanced Amateur Radio
Noise Filtering	Manual adjustments of RF gain, notch filters, and fixed audio DSP width.	Dynamic neural networks that isolate human voice or code from background electrical hums.
Band Hunting	Manual tuning across a VFO dial or tracking simple text-based DX cluster alerts.	Predictive spectrum scanning prioritizing frequencies based on real-time solar telemetry.
Digital Decoding	Exact mathematical pattern-matching; fails if signal drops below the hard theoretical noise floor.	Generative packet-filling and probabilistic decoding of compromised data streams.
Shack Maintenance	Manual reading of complex paper schematics to build antennas or debug circuitry.	Computer vision and LLMs that troubleshoot physical circuit designs or guide antenna cuts via photo inputs.

---

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.
