There is a particular thrill in hearing a voice come back to you out of the static for the first time. Mine came as M7RJJ, on a Foundation licence I had spent months working up the courage to use. More than five years later, I sit in the same shack (it’s also my work-from-home office) as M0LGI, and the journey between those two callsigns has been one of the most rewarding things I have ever done.

This is the story of how I got there, and a few honest reflections on what the path actually felt like.

It started with a curious child

My fascination with radio goes back further than I can properly remember. There is something almost magical about the idea that a voice, a song, or a Morse code character can travel hundreds or thousands of miles through nothing but air and ionosphere. As a child, I would tune through the shortwave bands on the family radio and listen to broadcasts from places I could barely find on a map. I did not know it then, but the seed was already planted. What I barely realised as a child was that ordinary people could actually do this themselves.

I also remember a visit to the local town show where the (now defunct, I think) Dudley and District Amateur Radio Society took over a ballroom at Himley Hall to house a ham station for the weekend. Everything was there from Analogue Fast Scan TV to the noisy RTTY teleprinters. I probably had a very glazed look on my face as I went round the room, listening to the chatter and ‘Donald Duck’ like noises of off-tune SSB.

The discovery that amateur radio was a thing, and that with a bit of study I could be on the air talking to those distant voices rather than just listening to them, lit a spark, but it would be many years before I could convince myself that I had both the time and technical literacy to do it.

I’m not from a scientific family. I’m from a council estate in Dudley. I was the first in my family to get any qualifications (seriously, I don’t think my parents, aunts and uncles have as much as an O Level between them) I’m also colourblind, so while I was always ok with things like code, circuits and resistors are largely impenetrable to me. I’m also a ‘words guy’ (politics degree).

My maths ability is poor, and it took me three attempts to get my GCSE. The only reason I persisted was that I needed it to get into university. Despite that, I decided, aged 38, that maybe I should find something to do now that I was married and had given up on ‘wine, women and song’.

Foundation Licence: the first hurdle

The Foundation licence is designed to be welcoming, and on paper it is. In practice, sitting down with the syllabus for the first time was still a moment of doubt. There were diagrams I did not understand, rules I had not encountered before, and an alphabet soup of terms that all seemed to mean something slightly different.

I got there with repetition. Lots of repetition. Flashcards became my best friend, and I drilled them on the train, in the kitchen, and in those quiet five minute gaps that turn up during a working day.

When the pass came through, and M7RJJ landed in my inbox, I held off transmitting for nearly a week. The first contact, when it finally happened, was a short and slightly stumbled exchange that I will never forget.

Intermediate Amateur Licence: the licence I cannot quite remember

Here is a confession that feels apt for a blog about memory. I cannot, for the life of me, recall my 2E0 callsign.

I held it. I used it. I made contacts with it. And somewhere in the move from Intermediate to Full it slipped out of my head and never came back. There is something quite funny about that, given how much of this whole journey has been about wrestling with a memory that does not always cooperate.

The Intermediate exam itself was a genuine step up. The maths started to bite, the regulations grew teeth, and the practical element forced me to actually solder rather than just nod along to a diagram. It took longer than Foundation, with more false starts and more evenings spent staring at a textbook or following a self guided online course, wondering why I had ever thought this was a good idea. But each small breakthrough felt earned, and that mattered.

The full amateur radio licence: the long climb

The Full Licence was where the journey nearly stalled. The syllabus is broader, the maths is much harder, and the volume of material to retain is genuinely demanding. For someone whose memory is, let us say, selective, this was the part of the path that demanded the most patience.

I gave up on cramming and went back to what had worked for Foundation level. Repetition. Flashcards. Little chunks, often. I would tackle one topic at a time, drill it until it stuck, then move on. When something refused to land, I would leave it and circle back a week later. Sometimes it had quietly taken root in the meantime. Sometimes it had not, and I would start again.

I studied with Bath and District Amateur Radio Club remotely. I can’t say enough good things about the syllabus and the quality of the teaching. But, I still had a false start, where I had to delay my entry and take the next course, due to feeling overloaded with the pressure from my then day-job.

The process took a solid five months from the initial assessment quiz (that I took on holiday in Greece) to the completion of the course. This was weekly 2 hour Zoom lessons and massive amounts of reading material and doing other online teaching modules and watching YouTube videos for more details, as well as building physical circuits.

The exam day itself was nerve wracking. It’s something you can do from home as long as you have an additional camera that can see you from behind and see under your desk. It was a Sunday morning in Mid-January and I had 2 hours to complete the exam.

I remember reading questions twice, then three times, convinced I was missing something. I got to the end, and the multiple-choice test was marked in an instant. When the pass came through, the feeling was not so much triumph as relief. M0LGI was issued a few days later, and a chapter that had taken more than five years finally closed.

The contact that made it all worth it

While the plan for the future is to operate overseas in France and Greece while staying with family (something you can’t do without the HAREC certification that comes free with a full amateur radio licence), the thing that made me think I was on the right course came early courtesy of my Xiegu G90.

Every operator has a contact that sticks with them. Mine happened while I was still M7RJJ, running the 10 watts that the Foundation licence then allowed. Ten watts is not very much. It is roughly the power of a dim light bulb, and the conventional wisdom is that you should not expect miracles from it on HF.

That afternoon I worked the ARRL Headquarters station in the United States. This is the US equivalent of working the UK’s National Radio Centre.
I still remember the moment my callsign came back across the Atlantic. Ten watts from a modest UK station, into the headquarters of American amateur radio. It was the sort of contact you read about in magazines and quietly assume happens to other people. The exchange was short, as contest exchanges always are, but the meaning of it was anything but small. A handful of watts had crossed an ocean. Every flashcard, every late evening with a textbook, every moment of doubt felt repaid in that one short exchange.

That is the thing about amateur radio. The reward is not the licence itself. The licence is just a door. The reward is everything that happens once you walk through it.

What I would tell my Foundation licenced self

If I could send a message back to the operator who first keyed up as M7RJJ, it would be short.

You are going to forget your Intermediate callsign. That is fine. You are going to find some exam topics harder than you expected. That is also fine. The journey is not a race, and the operators you meet on the air will not care how long it took you to get there. Take it at the pace your memory and your life will allow, lean on repetition when the material refuses to stick, and remember why you started.

A child once listened to voices coming out of the static and wondered how on earth they got there. More than five years of study answered the question. The answer is that you put in the hours, you trust the process, and one quiet evening, a signal finds your antenna and the whole thing makes sense.

73 from M0LGI, formerly M7RJJ, and briefly something with a 2 in it that I really should write down somewhere.

If you have spent any time on the HF bands in recent years, you will know that digital modes have transformed amateur radio. FT8 and FT4 made it possible to work weak signals that would be lost in the noise on SSB or even CW.

Now there is a new arrival on the scene, and it is faster than anything that has come before it. It is called FT2, and this post will walk you through what it is, how it works, and why so many operators are excited about it.

So, what is FT2?

FT2 is a digital mode designed for amateur radio, built specifically for short, efficient contacts on the HF bands. It was created by Martino Merola, callsign IU8LMC, with the support of ARI Caserta in Italy. The very first FT2 contact in the world took place on 16 February 2026 between IU8LMC and IZ8XXE on the 40 metre band.

The headline figure is the cycle time. Where FT8 uses a 15-second transmit and receive cycle, and FT4 uses 7.5 seconds, FT2 squeezes the same job into just 3.8 seconds. That makes it roughly four times faster than FT8, with a complete contact typically wrapping up in around 6 seconds.

How does it relate to FT8 and FT4?

This is where things become reassuring for anyone already familiar with the existing modes. FT2 uses the same underlying codec as FT8 and FT4. The 77 bit payload, the LDPC(174,91) forward error correction, and the 4-GFSK modulation are all identical. In other words, FT2 is not reinventing the wheel. It takes the trusted protocol core that has been refined over the years and packages it into a much shorter cycle.

What makes the difference is how that information is transmitted and decoded. The transmission bandwidth is wider at 167 Hz (compared with 50 Hz for FT8 and 83 Hz for FT4), and the effective transmit time is much shorter at around 1.89 seconds. Combined with a clever new decoding engine, this produces a mode that is both fast and remarkably sensitive.

The numbers that matter

A quick comparison helps put FT2 in context:

Parameter	FT8	FT4	FT2
Cycle time	15 seconds	7.5 seconds	3.8 seconds
Bandwidth	50Hz	83Hz	167Hz
Sensitivity	-21db	-16.5db	-23db
Full QSO	~60 seconds	-30 seconds	-6 seconds
Max contacts per hour	60	120	450

That sensitivity figure of -23 dB SNR is particularly impressive. It means FT2 can pull signals out of the noise that are weaker than what FT8 can manage, which is no small achievement given the shorter cycle.

The Raptor Engine and Shannon’s limit

The software that powers FT2 is called DECODIUM, and the current decoding engine is named Raptor. Without getting too technical, Raptor uses a refined approach to digital signal processing that pushes performance close to what is mathematically possible.

Claude Shannon, the father of information theory, proved back in 1948 that every noisy channel has a theoretical maximum capacity. The Raptor engine is described by its developers as operating at the practical limit of Shannon’s theorem for 77 bit blocks on HF. As the project’s tagline puts it, “more power is not the answer, better math is.”

Asynchronous transmission

One of FT2’s most interesting features is asynchronous transmission, or ASYMX as it is called in the software. Traditional digital modes require all stations to be synchronised to a precise clock, usually using NTP or GPS. FT2 does away with this requirement. It begins transmitting within about 300 milliseconds of decoding the previous message, with no need for the even and odd time slot dance that FT8 operators will recognise.

For new operators, this means you do not need to worry quite so much about keeping your computer clock perfectly aligned. The mode works around clock drift and timing variations in a much more flexible way.

FT2 – Officially recognised by ADIF

A digital mode is not really part of the amateur radio mainstream until logging software supports it properly. FT2 cleared this hurdle on 22 March 2026, when the ADIF Development Group voted unanimously, 22 to 0, to include FT2 as an official submode in ADIF 3.1.7. This was the highest participation ever recorded by the group, and it means every major logging platform now recognises SUBMODE=FT2. Names you will know, including LoTW, DXLab Suite, Log4OM, Cloudlog, eQSL, Wavelog, and Fldigi, all voted in favour.

Getting started with FT2

The software you need is called DECODIUM 4.0, codename Shannon. The latest public beta was released on 19 May 2026, and it is available as a free download for Windows, macOS (Apple Silicon), and Linux. There is also a Raspberry Pi port for anyone wanting to build a compact portable FT2 station.

You can find the official downloads at ft2.it, and there is a Telegram beta group where you can ask questions and get help from other operators. With over 2,000 active operators and more than 500,000 QSOs logged across 40+ DXCC entities, the community is already a healthy size for a mode this young.

Should you try FT2?

f you already enjoy FT8 or FT4, the learning curve for FT2 is gentle. The on-screen workflow is familiar, the message structure is the same, and your existing rig and interface should work without modification. The main differences you will notice are the rapid pace and the absence of strict timing constraints.

For contesters and DXers, the appeal is obvious. Roughly 450 contacts an hour is a serious rate, and the improved sensitivity means you stand a better chance of working that rare station whose signal is barely audible. For more casual operators, FT2 offers a chance to make many short contacts in a single session without committing to the longer cycles of FT8.

Either way, FT2 is a notable step forward for amateur radio digital modes. It builds on what FT8 and FT4 established, takes advantage of modern computing power, and pushes performance close to the mathematical limits of what is possible. Whether you are a seasoned digital operator or just starting out, it is well worth a look.

73, and good luck on the bands.

What is FT8 and Why Should Foundation Operators Care?

FT8 (Franke-Taylor design, 8-FSK) has revolutionized amateur radio digital communication since its introduction in 2017. For Foundation licence holders operating with limited power and antenna restrictions, FT8 offers an incredible opportunity to make worldwide contacts that would be impossible with traditional voice modes.

This weak-signal digital mode can decode signals as much as 21 dB below the noise floor, making it perfect for QRP (low power) operations. With just 10 watts and a modest antenna, Foundation operators can regularly work DX stations across the globe.

Understanding FT8: The Technical Basics

FT8 uses 8-tone frequency-shift keying (8-FSK) with a symbol rate of 6.25 symbols per second. Each transmission lasts exactly 12.64 seconds, followed by a 2.36-second gap, creating precise 15-second time slots. This timing synchronization is crucial – your computer’s clock must be accurate to within ±1 second for successful decoding.

The mode occupies just 50 Hz of bandwidth and uses structured messages that follow a specific protocol. A typical FT8 QSO consists of six transmissions (three each way), exchanging callsigns, grid squares, and signal reports automatically

The Soundcard Interface: Your Digital Gateway

The connection between your transceiver and PC soundcard is the heart of any FT8 station. This interface allows your computer to generate the audio tones for transmission and receive audio signals for decoding.

Audio Connections

Most operators use one of three interface methods:

Built-in Soundcard Interface: Many modern transceivers include USB connections that provide both audio in/out and CAT (Computer Aided Transceiver) control. Popular models like the Yaesu FT-991A, Icom IC-7300, and Kenwood TS-890S offer this convenience.

External Sound Interface: Dedicated amateur radio interfaces like the SignaLink USB or RigBlaster series provide audio isolation, level matching, and PTT (Push-to-Talk) control. These units protect both your radio and computer from ground loops and audio level mismatches.

Simple Soundcard Connection: Budget-conscious operators can build basic interfaces using audio isolation transformers and PTT switching circuits, though this requires more technical knowledge and careful level setting.

Audio Level Management

Proper audio levels are critical for FT8 success. The transmit audio should drive your transceiver to approximately 25-30 watts output (for 100-watt radios) while maintaining clean modulation. Most FT8 software includes built-in level indicators and ALC (Automatic Level Control) monitoring to help optimize settings.On the receive side, audio levels should provide good signal strength in the software without overloading the soundcard input. Too much gain can cause intermodulation distortion, while too little reduces weak signal sensitivity.

Essential Software for FT8 Operations:

WSJT-X remains the gold standard for FT8 operations. Developed by Nobel Prize winner Joe Taylor (K1JT), this free software handles all aspects of FT8 communication, from frequency coordination to log integration.

JTDX and JS8Call offer alternative implementations with additional features. JTDX provides enhanced band activity displays and contest features, while JS8Call enables keyboard-to-keyboard messaging using FT8 technology.

Most operators also use logging software like Ham Radio Deluxe, N1MM Logger+, or LOTW (Logbook of the World) integration for contest participation and QSL management.

Band Planning and Frequency Coordination

FT8 operates on specific frequencies within each amateur band. Foundation licence holders should focus on:

40m: 7.074 MHz (most popular for domestic contacts)

20m: 14.074 MHz (excellent for DX during daylight hours)

80m: 3.573 MHz (good for evening local/regional contacts)

10m: 28.074 MHz (sporadic E and solar cycle dependent)

The software automatically manages frequency coordination within the ±3 kHz FT8 sub-band, but operators should monitor band conditions and QRM levels when selecting their operating frequency.

Station Setup and Configuration:

Computer Requirements:

FT8 demands accurate timing synchronization. Install time synchronization software like Meinberg NTP or Dimension 4 to maintain clock accuracy. Most modern computers can handle FT8 processing easily, but avoid running processor-intensive applications during operation.

Antenna Considerations for Foundation Operators:

While FT8’s weak-signal capabilities work miracles, a good antenna system remains important. Foundation operators often achieve excellent results with:-

Wire antennas: End-fed half-waves, dipoles, or random wires work well

Vertical antennas: Ground-plane or end-fed verticals for DX work

Magnetic loop antennas: Excellent for restricted spaces, though bandwidth-limited

Even compromised antennas can produce surprising results with FT8’s digital signal processing advantages.

Operating Procedures and Etiquette:

FT8 follows automated protocols, but good operating practices remain important. Monitor before transmitting, use appropriate power levels, and avoid calling stations you can’t copy clearly. The mode’s popularity can create crowded conditions, so patience and courtesy benefit everyone.

Understanding the message structure helps troubleshoot problems. Watch for partial decodes that might indicate timing or level issues, and adjust your station accordingly.

Troubleshooting Common Issues:

Timing Problems:

GPS disciplined oscillators or internet time synchronization solve most timing issues. Check your computer’s time against WWV or online atomic clocks.

Audio Interface Issues:

Ground loops, level mismatches, and RF feedback cause most audio problems. Proper grounding, ferrite cores, and appropriate interface equipment resolve these issues.**Decode Problems**: Poor receives often result from computer overloading, inadequate antenna systems, or local interference. Address each potential cause systematically.## Advanced Techniques for Foundation Operators

Grid Square Optimisation: Learn your Maidenhead grid square and surrounding grids to maximize contact opportunities during contests and DXpeditions.

Band Condition Awareness: Monitor propagation predictions and solar indices to optimize band selection and operating times.

Contest Participation: FT8 contests offer Foundation operators excellent opportunities to work rare stations and improve their digital operating skills.

Conclusion: Embracing Digital Communication

FT8 opens incredible communication opportunities for Foundation licence holders. The mode’s weak-signal capabilities, combined with modest equipment requirements, level the playing field between QRP and high-power stations.

Success with FT8 depends on proper station setup, good operating practices, and understanding the technology behind the magic. Start with basic equipment, learn the software thoroughly, and gradually optimize your station for maximum performance.

The future of amateur radio increasingly includes digital modes like FT8. Foundation operators who master these techniques position themselves for decades of exciting communication adventures, regardless of power limitations or antenna restrictions.

Whether you’re working your first transatlantic contact or chasing rare DX entities, FT8 proves that in amateur radio, technical knowledge and good engineering often matter more than raw power. For Foundation licence holders, that’s particularly good news.

Amateur radio satellites represent one of the most ambitious and successful grassroots efforts in space technology. For over six decades, radio amateurs worldwide have designed, built, and operated dozens of satellites that have advanced both space science and global communications. These miniature spacecraft, often built on shoestring budgets by volunteers, have pioneered technologies later adopted by commercial and military satellite systems.

The Dawn of Amateur Radio in Space

The amateur radio satellite program began during the early years of the Space Age. On December 12, 1961, just four years after Sputnik, OSCAR-1 (Orbiting Satellite Carrying Amateur Radio) became the first amateur radio satellite launched into orbit.

Built by Project OSCAR in California, this modest 10-pound spacecraft transmitted a simple “HI” message in Morse code for 22 days before its batteries died.

OSCAR-1’s success demonstrated that dedicated amateurs could design and build functional spacecraft. The satellite was launched as a secondary payload aboard a military mission, establishing a cost-effective model that amateur radio satellites continue to follow today. This achievement proved that space technology wasn’t exclusively the domain of superpowers and large corporations.

The early OSCAR missions laid crucial groundwork for what would become a thriving amateur satellite community. OSCAR-3, launched in 1965, became the first amateur satellite to carry a transponder, allowing two-way communication through space. This innovation transformed amateur radio satellites from simple beacons into genuine communication tools.

Evolution Through the Decades

The 1970s and 1980s saw remarkable advancement in amateur satellite capabilities. OSCAR-6 and OSCAR-7, launched in 1972 and 1974 respectively, featured sophisticated transponders operating on multiple frequency bands. These satellites enabled thousands of radio amateurs to experience space communication for the first time, with OSCAR-7 remarkably still functioning intermittently today, nearly five decades after launch.

The introduction of Mode B operation (435 MHz uplink, 145 MHz downlink) became a standard that persists today. This frequency arrangement allowed for efficient satellite communication while minimising interference with terrestrial amateur radio operations.

The success of these early missions established amateur radio satellites as a legitimate and valuable part of the amateur radio service.During the 1980s and 1990s, amateur satellites became increasingly sophisticated. Phase 3 satellites, built by AMSAT (Radio Amateur Satellite Corporation), featured highly elliptical orbits that provided extended coverage periods over specific regions. These satellites, including OSCAR-10 and OSCAR-13, offered near-commercial quality communication links and supported emergency communications during natural disasters.

Technical Innovation and Miniaturisation

Turn of the millennium brought revolutionary changes to amateur satellite technology. The development of CubeSat standards dramatically reduced the cost and complexity of satellite construction. These tiny spacecraft, measuring just 10 centimetres on each side, made satellite development accessible to universities, high schools, and smaller amateur radio groups.

CubeSats enabled a new generation of experimental satellites that pushed technological boundaries. Digital communication modes replaced traditional analogue transponders on many missions, offering improved efficiency and new capabilities. Satellites began incorporating advanced features like software-defined radios, GPS tracking, and sophisticated digital signal processing.

The miniaturisation trend also led to the development of “picosatellites” and femtosatellites, some weighing less than a kilogram. These ultra-small spacecraft demonstrated that meaningful space missions could be accomplished with minimal resources, inspiring educational programs worldwide and making space technology accessible to students at all levels.

Current Applications and Services

Today’s amateur radio satellites serve diverse purposes that extend far beyond simple communication. Linear transponders continue to provide voice and digital communication services, but modern satellites offer much more sophisticated capabilities.

Digital store-and-forward messaging has become increasingly important, particularly for emergency communications. Satellites like the International Space Station’s amateur radio equipment regularly handle message traffic during disasters when terrestrial infrastructure fails. These systems can store messages uploaded from one location and download them when the satellite passes over the destination region.

Educational outreach represents another vital current application. School contact programs allow students to communicate directly with astronauts aboard the International Space Station, inspiring interest in science, technology, engineering, and mathematics. These programs have reached millions of students worldwide and continue to grow in popularity.

Experimental and scientific applications showcase amateur radio’s contribution to space technology development. Amateur satellites test new communication protocols, antenna designs, and space-qualified components. Data collected from these missions often benefits commercial satellite developers and space agencies, demonstrating the continued relevance of amateur space programs.

Modern Network Architectures

Contemporary amateur radio satellites increasingly function as nodes in global digital networks rather than isolated communication platforms. Packet radio networks using amateur satellites provide store-and-forward messaging capabilities that complement internet-based systems. These networks prove particularly valuable in remote areas where traditional internet infrastructure is unavailable or unreliable.

The development of the automatic packet reporting system (APRS) via satellite has created a global position reporting and messaging network. This system allows mobile stations to report their positions and exchange short messages through satellite links, supporting activities ranging from emergency response to expedition tracking.

Some modern amateur satellites incorporate internet gateways, allowing messages to flow between satellite-based networks and terrestrial internet systems. This hybrid approach leverages the strengths of both satellite and terrestrial communications while maintaining the amateur radio emphasis on experimentation and emergency preparedness.

Emergency Communications Role

Amateur radio satellites have repeatedly demonstrated their value during emergencies and disasters. When terrestrial communication systems fail due to natural disasters, satellite links often remain operational, providing critical communication capabilities for emergency responders and affected populations.

Hurricane response operations frequently rely on amateur satellite communications to coordinate rescue efforts and relay health and welfare messages. The global coverage provided by amateur satellites makes them particularly valuable for oceanic search and rescue operations where other communication means are unavailable.

The decentralised nature of amateur satellite networks provides resilience against systematic failures.
