It's fascinating to me that this looks like half a dozen or so radio stations I've been in. It's especially fun at 1am in the morning.. (*)

Only one station I've been at looks completely different, ABC Radio in Perth, but that was purpose built 20 years ago and it's also a TV station.

(*) I have scared the crap out of myself and others on more than one occasion because radio studios are sparsely populated and sound dampening is essential.

To enjoy yourselves doesn't require that you all buy the latest gaming rig or even something new or identical. As long as what you decide on has games in common, you're good.

I can't ever see this happening.

The thing that gets me about healthcare is that we seemingly continue to train specialists who focus all their attention on one single aspect of the human body to the exclusion of everything else, even though the more we learn about how it works, the more interconnected it all appears.

This saying comes to mind: "If all you have is a hammer, every problem looks like a nail."

I'm not eligible to vote in your country. In mine, voting is mandatory and there are no stickers, just democracy sausages to aid in the funding for local polling places like schools and community halls.

Until just now I had never heard of this team and their contribution to FreeCAD. Reading the article I think it outlines what they did and it sounds excellent.

As far as their success or failure of achieving their aims, I don't have any information to make a judgement either way.

I will say that making a business out of open source software is not something for the faint of heart and not something that has a track record of success, let alone a documented one. Mostly it seems to follow the pattern: "How do you make a small fortune from open source?" "Start with a large fortune."

I say this as a quarter century user, developer and advocate of open source solutions.

The thing about free speech is that there's a whole lot of legislation surrounding it. At the moment, every single fediverse instance is run by( a small group of) people, many of them are run by individuals who are legally responsible for the content that's posted on their site.

In addition, the Digital Millennium Copyright Act, better known as the DMCA and the General Data Protection Regulation, the GDPR, have requirements for people who own and publish data, like the people who run instances, not to mention privacy acts and myriad other provisions and laws.

Non compliance is very easy and costly, so instances who are aware of this are cautious in what they allow on their instance.

Finally, many instances want to create a community with a social cohesion and associated standards that they, depending on the level, encourage or enforce.

Why any instance bans something at any one time can generally be traced back to these reasons.

Of course there are also instances where it's completely open season. Don't expect these to stick around once lawyers get involved.

As I sit here, away from my shack, I'm overlooking a picturesque valley that I'm visiting for a couple of days to see the stars. I learnt recently that my SO, Significant Other, had never seen the Milky Way with their Mark One Eyeball and we thought that it would be fun to remedy that.

One of the challenges in accomplishing this is that we're surrounded by light almost everywhere we go. Street lights, porch lights, car lights, stadium and building lights, traffic lights, even emergency lighting on various towers dotting the landscape.

Last night we laid on our backs on a picnic blanket tucked into a sleeping bag, looking up at the sky. The valley where we are is pretty good, there's much less light pollution than in the city, but it's not pitch black. We fantasised about knocking on neighbours' doors to ask them to turn off their porch lights, but quickly came to the realisation that this was not going to be either acceptable, or reasonable.

While I entertained the notion of creating a community Milky Way watching event, increasing local awareness of the new moon, light pollution and making it a local monthly event I discovered that Astro Tourism is a thing and our location happens to be part of the local scene.

Of course I couldn't help myself and started explaining to my SO about how light and radio are the same thing when it struck me that in our hobby we have a similar issue.

We don't refer to it as light pollution, instead we call it noise, specifically, QRM, or man-made noise, as opposed to QRN, natural noise.

I wondered what a community event might look like if we did this with radio amateurs, rather than star gazers. How far would we need to go to get away from noise and could we realistically make something that was actually noise free?

In reality the radio gear we bring, the power supplies, the solar panels, generators, inverters, computers and pretty much all the other stuff to make life come with radio noise to more or lesser degree.

How could you set up an event where that type of noise was contained? Could it be done? What would it take?

On a small scale, I can go to my local park with a fully charged 12 volt battery and a radio and get some sense of what it might look like, but all that really does is whet your appetite. What does this sound like if it's really quiet?

For star gazers, there is a project called DarkSky with a .org website. It documents where designated Dark Sky Places are and promotes the protection of communities from the effects of light pollution through outreach, advocacy and conservation.

We as radio amateurs could do with such a thing. What would our radio quiet spaces look like? How would we find them, how would we coordinate our efforts and what would outreach, advocacy and conservation look like for a radio quiet space?

From a star gazing perspective, I've experienced the middle of nowhere, Lake King in Western Australia, in a paddock, lying in my swag, looking up. The sight is overwhelming. I felt like I was falling, even though I was lying flat on my back, physically not moving.

I wonder what such a level of quiet looks like with a radio?

The other day I was handed a sheaf of paper. The person handing it to me, an amateur, was insistent that I take custody of this little collection. I asked what it was that they intended for me to do with it and the response was that because I did things with history, I should do this too.

Aside from taking on a new project, trying to juggle life and income, their observation was pretty spot on, even though I had never quite seen it in that way. Over the years I've often explained things in the context of the era in which it came into being, the first transatlantic telegraph cable in 1858, the first 20m contact between the UK and Australia, back in 1925, the founding of the IARU, also in 1925.

For some years I've been playing with the idea of documenting the journey from Spark Gap to SDR. I started writing down milestones, collecting information about the various protagonists along the way, attempting to capture their life milestones and their radio related accomplishments. One friend went so far as to take photos of the replica spark gap transmitter in Hobart, Tasmania as used by Douglas Mawson between 1911 and 1914 during their Antarctic expedition.

Between being entrusted with the written history of 28 Chapter of the Ten-Ten International Net and today I've started a spreadsheet. If you know me at all, you know that I love a good spreadsheet. This one is pretty simple, date, event, event type, protagonist, note and source. So far I've got about 85 rows. I'm using it to capture milestones directly related to our hobby, when the first EchoLink node went live, when RTTY came to be used on-air, the invention of FM, when we got access to the 2m band, when 160m was taken away during World War II, ultimately, all of it.

There is already a website that documents some of this but it's USA centric, even though our community is global, and it does not include any sources, so there's no way to verify any of the events, which I think is essential if you're going to capture this in any meaningful way.

I want this list I'm creating to include all manner of amateur related things, the first time F-troop went on-air, the first CQWW, perhaps even every CQWW. I have also set-up a form so you can contribute your events and over time grow it into something that captures what it is that we've done over the years. Perhaps it will grow into a section on Wikipedia, perhaps it will become its own thing, it's too early to tell.

As I've said many times, if you didn't write it down, it didn't happen. So, this is me, or us, writing it down. Perhaps we'll be able to find a way to make it through the next 100 years.

You can find the Amateur History Project under Projects on my home-page at vk6flab.com - I look forward to reading your contributions.

So, thank you Christine, VK6ZLZ for pushing that sheaf of paper into my hands. I hope I'm worthy of the history that it represents.

To get into the hobby of amateur radio is easy, but that doesn't mean it's simple. I was introduced to the hobby three times.

The first time I was a Sea Scout in the Netherlands. It was JOTA, the annual Jamboree On The Air and radio amateurs across the planet were set up at various Scouting locations with their stations showing off how to make contact with far away places.

My memory of it is brief. I recall a green heavy army tent with radios on a table. There was noise everywhere. I was told that I was hearing a station in Brazil, which seemed incongruous, given that I was standing on an island surrounded by other Sea Scouts, a place where I had been camping and sailing for several years.

We trooped out of the tent and ten minutes later I broke a finger playing a game where you sat on a mast trying to upend the other person using a canvas bag with a jib in it. I was unceremoniously upended and landed poorly and broke the middle finger on my right hand. Being a teenager that was of course a source of immediate ridicule and innuendo and getting a dink, that's Aussie slang for getting a ride on the back of the pushbike of my boatswain to the local hospital, after rowing from the island to the mainland caused me to completely forget that amateur radio experience.

The second time I came across the hobby was through my then manager, Ian, whom I now know as VK6KIH, but at the time he was a quiet spoken man thrust into the role of manager. The introduction came in the form of a Daihatsu Charade with a massive, what I suspect, was a 40m HF whip. The amateur radio aspect made little or no impression. The antenna, clearly much too large for such a tiny vehicle, did. I don't recall ever talking about amateur radio or even seeing his setup. Come to think of it, I'm not sure if I ever have.

The third time I came across the hobby was at a dinner table surrounded by fellow "dogcow" geeks. One of them, Meg, then with the callsign VK6LUX showed us her brand new shiny purchase, a drone, that could be controlled remotely via WiFi on 2.4 GHz. She went on to tell us that the range was pretty limited because it was WiFi, but because she was a radio amateur, she was going to experiment with an amplifier. This was permitted because as I learnt, the 2.4 GHz WiFi frequencies are shared with amateur radio. You might know it as the 13cm band.

I asked about this thing called amateur radio. I wanted to know what was involved, how would you become one, what would it cost, you know, all the things everyone always asks. I was told that there'd be a course in two weeks with an exam the weekend after. I asked if we needed a group booking and was told to "just rock up".

So I did.

I got my license in 2010 and my world changed forever. I will add, just to make sure that if you're planning to do this, that during my course I discovered that my license wouldn't permit my use of the 13cm band, so I'd have to upgrade. I promptly purchased the requisite course material and started reading. In the mean time I got distracted by the activities at a local club, then I bought a radio, then I was told I wasn't a real amateur because I only had a beginners' license, so to prove a point, I started having fun with my license. I haven't stopped since.

Now, some, or maybe all of this, I've shared before. Here's something new.

I'm a so-called A.F.O.L, or an Adult Fan Of Lego. It's not a guilty pleasure, I'm happy to admit it. I have too much Lego around me. My oldest set is from 1964, House with Garage, number 324-2. It's not complete any longer, the car is long gone, the garage door weights are broken off, but it has pride of place in my living room. History does not reveal how I came into possession of it. Best I can reconstruct is that in the deep dark corners of Australia it takes a little while for kits to arrive, since I was born after the kit came into existence. I do know that I had it before 1976.

The other day I was watching a documentary about Lego and one thing stood out to me. I'll share the entire quote by Kjeld Kirk Kristiansen the then President and CEO of The Lego Group:

"During the 1990s, we kept thinking that much more should be done for the adult "hobbyist builders," as we called them at the time. Most people on the management team thought we should concentrate on children instead, but I felt that a person could have an inner child at any age."

Why this is important is because of my activities as a radio amateur. We as a community keep saying that we should grow, that we're losing too many people, that we need to engage with S.T.E.M., or Science, Technology, Engineering and Mathematics. Whilst that may be true and whilst JOTA and Scouting might give us exposure to fresh new people, there's a massive community of adults who already know about our hobby. They just don't yet know how it might interact with them, personally, or how they might find it interesting, or engaging, rewarding, and all the other things that you as an amateur already know about.

So, if there's Adult Fans Of Lego, why not Adult Fans Of Amateur Radio?

While thinking about that, how would you talk to them, how would you go about finding them, relating their interests to our hobby, finding common ground and discovering even more things that we can add to the thousands of amateur activities we already know about?

The other day I lamented to a fellow amateur that my shack was not functioning well. Specifically, my main workstation died three months ago and ever since I've been struggling to reclaim my productivity. One aspect of that is my desk. For half a decade or so I've had my computer clamped to a rolling lectern. It allowed me to move around my office as my mood and the light from the window changed.

During the weekly net I'd move my lectern and computer next to my radio and host the net whilst logging on my computer.

That's no longer possible because of a number of reasons, so instead I was trying to accomplish the same thing on a tiny 13 inch screen which didn't work for me. My friend asked me why I hadn't just extended the microphone lead from my radio, so I could sit at my now stationary computer and still key the microphone. I located an Ethernet joiner, an Ethernet cable and did just that. Simple. Job done.

Then I started wondering why I wasn't on HF with my station and if there was a simple solution that was eluding me. Spoiler alert, it still eludes me. The requirements are not too complicated, well at least in my mind they're not.

I want to operate on HF. I want the computer to not be physically, or specifically, electrically connected to the radio, in any way. I need to be able to use logging software that tracks the radio band, mode and frequency. I'd like to use digital modes, I'd like to have a computer controlled voice keyer and I do not want to run Windows and if I can at all help it, I'd like to spend as little time as possible doing this without spending an arm and a leg.

So, then I started wondering what this looks like for other people. What kinds of compromises have you made in your shack? What have you accomplished and how did you get there? What choices of hardware and software did you make, and why? Did you give up, or face the challenge head on? How did you gather information and how did you find out what others did?

Not for a moment do I think that this is a simple thing to solve, but it's clear to me that I'm so far down the complicated rabbit hole that I'd like someone to show me the light at the end of the tunnel to make some progress.

Of course I've not been idle while all this is happening. I configured a Raspberry Pi, a small single board computer, to talk to my radio via USB. I connected a sound card to the audio connector on my radio. Theoretically this should give me all that I need, but the difference between theory and practice is common knowledge, in theory it works, in practice it doesn't. The Pi is a few years old, but it's not doing much at all. It connects to my network wirelessly, so my main computer isn't physically connected to the radio, but it's still pretty unreliable and I have to say, calling CQ, either using voice or digital modes, should be rock solid. You don't want your radio to keep transmitting after it's supposed to and other little issues like that.

So, how did you do this? I'm interested to know. I'm not the first person to run into this issue and I'm not the last. Your experience might help me and it might help others. Drop me an email, [email protected] and I look forward to hearing about your adventures.

At my local hamfest on the weekend I picked up this 6-way coax switch. I've been furiously searching my little heart out, but haven't actually discovered any sign of it.

How do I wire this up? What do I need? What specifications does it have? Anything you can share?

The International Amateur Radio Union or IARU, is the governing body of our community. It represents us on the world stage through the International Telecommunications Union, the ITU. As I've discussed before, it consists of four separate organisations working together, the International Amateur Radio Union, the global body, and three regional ones, Region 1, 2 and 3, each representing the hobby of amateur radio. Previously I've looked at the constitution of the IARU to get a sense of its purpose in the world.

At the time I mentioned the notion of comparing the four organisations against each other, since ostensibly they're doing the same thing for a different part of the world.

Each of these regional bodies was created separately by different groups of people and their constitutions reflect that. The Global IARU constitution, last updated in 1989 consists of nine pages. The IARU Region 1 constitution, with proposed amendments from 2020 has 31 pages, the English version of the Region 2 constitution, since there's also a Spanish one, was amended in 2019 has six pages including two copies of Article 2, and refers regularly to the Global IARU constitution and finally, Region 3, amended in 2012 has 15 pages.

What is striking at first glance is just how poorly these documents are constructed. Formatting, inconsistent spelling, indentation, general layout and all are lacking attention to detail. I think that this reflects poorly on the internal workings of the IARU, but I digress.

Curiously, the Region 3 website has a whole section on proposed changes to the constitution. Many of those changes are around the election of officials and voting procedures. It also includes the use of modern communications like email and remote conference facilities on internet platforms. One paragraph stood out: "It was also realised that changes would need to be made to formally recognise that we will (as happened at the online conference in 2021) have females as well as males taking responsible positions in IARU Region 3."

It must have come as quite a shock to the delegates to learn that there are females in our hobby. This must have already happened in Region 1, since there is a reference to "he/she" in relation to being elected. Mind you, use of the word "they" must not have occurred to the authors.

But don't worry, we shouldn't rush these things, the International body and the Region 2 constitutions both use "he" for roles. I will point out that the International body has a weasel clause where it states, among other things, "words importing only the masculine gender include the feminine gender and the neutral gender". It's a good start, but falls short of standards expected today.

If you're not sure what all the fuss is about, let me illustrate:

"The term of office of the President shall be for a period of five years from the date of ratification of porcupine nomination, and porcupine shall remain in office until the nomination of porcupine successor has been ratified."

If that felt jarring for you, you might get some sense of what it feels like for someone reading that with gender pronouns that don't match the text.

A better solution would be:

"The term of office of the President shall be for a period of five years from the date of ratification of their nomination, and they shall remain in office until the nomination of their successor has been ratified."

It's not the first time we've struck this type of issue. It's high time that we did something about it. Over a year ago, I pointed out that OM, Old Man, and XYL, eX Young Lady, were derogatory and we should replace them with OP, operator, and SO, significant other. A year before that I proposed a revision of the Amateur's Code to make its language inclusive and reflective of the wider community in which we operate.

I've had discussions with people who identify across the gender spectrum about much of this and the overwhelming feedback I received is that our community is Old White Men clamouring to grow the hobby without a clue that the words they use are part of the problem.

So, credit to Region 1 for implementing some of this and to Region 3 for starting this conversation. I don't doubt that there are members in the Global IARU and Region 2 who would like to see this implemented and to you I say: It's time, high time, to review what language our community uses to identify itself to the wider community. More generally, as the governing and representative global bodies you should be leading the way and providing guidance to the member societies.

So, next time you promote our community, refer to others, link to articles, and attempt to encourage participation, you should take a moment and ask yourself if what you're saying is truly speaking to people who are not Old White Men and if that's the case, what you might do to embrace the wider community.

The standard you walk past is the standard you accept.

It's a serious question because so far, none have.

Edit: Some context for those asking.

Eternal September refers to a time when an online community was overrun by new participants to the detriment of that community.

When new people arrive piecemeal, like they're doing right now, they join in and participate. If they make little social mistakes, they are steered by members of the community in the direction that the community has evolved into by supplying social, language and behavioural cues.

New participants alter their behaviour and the community grows a little with the new participant. If they don't alter their behaviour, it's likely that they're removed from the community by some agreed process that has evolved over time.

If the growth is sudden, then the community will be overwhelmed by "blissful or deliberate ignorance" and the systems for cues, moderation and removal fail and the community, often drastically, changes or ceases to exist.

The reference to September is that's when new University Students would get an account on the University computer systems and join Usenet News. They'd arrive every September, there'd be a blip in adjustment and the Usenet communities would absorb the new members.

Eternal September arrived when AOL joined its bulletin board to Usenet and it completely overran everything with people from all across the AOL userbase, most of them not first year University students.

I was there when this happened, alt.best.of.internet (ABOI) was a community where I participated. One of many "new groups" it was alphabetically the first on the AOL list and it imploded. Together with Malinda McCall, I wrote the FAQ in an ultimately fruitless attempt at educating the masses.

I've seen this play out over and over again across the decades I've been online, so that's why I asked.

Getting started in our hobby can be a challenge. Even if you've got a shiny new license and you've been taught what the legal requirements are, you might even have your first radio, but after that it might feel like you're all on your own in this bright and shiny new world.

It doesn't have to be that way.

First thing to know is that you are exactly where all other amateurs have been before you. In other words, don't stress too much about what you don't know or what mistakes you might make. I recently read a comment from a new amateur who was so scared of making a mistake that they hadn't made their first contact. You should know that there is a massive difference between making an accidental mistake and knowingly interfering with another service.

Here's some mistakes I've made.

My license permits a maximum power level of 10 Watts. I dutifully set-up my radio to do just that, made my first contact on HF using 10 Watts, only to learn later that power levels are set separately for HF, 6m, VHF and UHF on my specific radio. So, the second time I keyed up my microphone, I was using 50 Watts. Not only that, I didn't quite understand how to set-up my radio for repeater use, so I keyed up on the output frequency and happily talked to the other station, blissfully unaware that I wasn't actually using the repeater.

It wasn't until several years later that I learnt that the minimum power level was 5 Watts on all bands, except UHF, where it is 2 Watts. And as icing on the cake, one day I managed a 2m contact across about 70 km, from my car. It wasn't until later in the night that I discovered that all the settings on my radio had reset and it was again using 50 Watts.

Another time I was in the club radio shack and having some fun with the club station. I tuned to a 2m frequency and called CQ. Didn't hear anything. Then I discovered that I'd missed a decimal point and was actually transmitting on the 20m band, where I'm not permitted with my license.

Each of those things are outside the restrictions of my license, but made by mistake, not on purpose. Instead of stressing about it, I went, oops, and carried on with a new lesson learnt. I will point out that I'm certain that there are more, mistakes, feel free to let me know.

Those concerns aside, finding people to talk to is another barrier to entry. We have all these bands and there's nobody about. It reminds me of a funny story I've shared before, told by Wally VK6YS, now SK. In his early amateur radio days he operated from Cockatoo Island, an island off the north coast of Western Australia, near Yampi Sound, which is where his callsign came from. With a new radio and transverter for 6m, Wally had been calling CQ for weeks, but nobody would talk to him. Occasionally he'd hear a faint voice in the background. Meanwhile it transpired that amateurs across Japan were getting upset that he wasn't responding to their 20 and 40 over 9 signal reports. His transmission was getting out just fine, his receiver wasn't working nearly as well. Turns out that during manufacturing, a pin on the back of his transverter hadn't been soldered correctly. Oops. Once he fixed that, he worked 150 Japanese stations on the first day and a lifelong love of the 6m band was born.

One hard learnt lesson is that the bands are constantly changing. If you cannot hear anything on one band, try another. If the band is quiet, it's likely because the conditions for that band are bad, but generally this is only true on HF. On VHF and UHF, the opposite is often true. Some bands, like 10m and 6m behave more like VHF, but not always. 20m can go from brilliant to abysmal and back in seconds, sometimes during the contact.

Each band has its own idiosyncrasies that you'll need to explore before you can hope to improve your chances of success and even years of playing will often get you surprises. I recall trying, for giggles only, to call CQ on a pretty quiet band only to score an unexpected contact with a Central European station on the other side of the globe.

A good rule of thumb is to go where the action is. If you can hear others, they're much more likely to hear you. While this is not universally true, it's a good starting point.

Of course, you don't need to physically have a radio to experience any of this. There are many websites that provide you with access to radio tuners. If you search for WebSDR or KiwiSDR you'll come across hundreds of online receivers that you can tune and operate on the frequencies they support using just your web browser. Some have the ability to decode digital modes within the web page, so you won't even have to install any extra software to play.

You might think that using such a receiver is not really amateur radio, but I'd like to point out that a transceiver is both a transmitter and a receiver. You can get the receiver right there in your web browser. The transmitter is a little more complex, but technically also possible. Many amateur clubs have a remote accessible station which will allow you to get started.

That kills two birds with one stone, you get to interact with the people in the club and you get to play on-air without needing to figure out just which radio to get and what antenna to connect it to and where to put either.

Other places to find new friends are of course social media, the so-called fediverse, a collection of social networking services that can communicate with each other, has several communities. You can get started at https://mastodon.radio and https://lemmy.radio. There's plenty of other on-air activities like Nets, discussion groups where you can get to know other amateurs. I run a weekly Net for new and returning amateurs called F-troop on Saturday morning midnight UTC for an hour, where you can say hello and ask questions. We pass the microphone around a circle, so everyone gets a go. You'll find more information at https://ftroop.groups.io.

Getting started does not have to be a daunting experience. Get on-air, make noise and before you know it, you'll have forgotten just how much you worried about things that really didn't cause any issues in the big picture.

If you're still stuck, drop me an email, [email protected] and I'll attempt to point you in the right direction.

What are you waiting for?

In the mid 1980's there was this thing called a Bulletin Board System or BBS. You would connect your computer to a gadget called an acoustic coupler that you would sit next to a telephone. You'd pick up the handset, dial a phone number and wait until there was a squeal in your ear. Then you'd push the handset into the rubber cups on the coupler and watch as your computer started putting characters on your screen.

Now, truth be told, my first foray was the next generation of this, an actual modem where you didn't actually have to touch the telephone, instead, the device could dial on your behalf using so-called AT commands.

And if we're being totally honest, I never actually connected to a BBS. My adventures with global communications started with Usenet News in 1990, but I'm here to make a point, I promise.

Amateur radio is a hobby that is for experimentation. One such experiment is a thing called packet radio. Before you roll your eyes about ancient technology, this gets very cool, very fast.

At its most basic, packet radio is about digital radio communication. Until not that long ago to play you needed a thing called a TNC or a Terminal Node Controller. When I got my license in 2010 I was told that this was a magic box to make digital communication possible between a radio and other radios and amateurs.

Right now, many people are playing with WSPR, Weak Signal Propagation Reporter as well as FT8, both examples of things intended to get specific chunks of information exchanged between two stations. What if I want to chat, or send a file, or a picture?

There are tools like "js8call" which is experimenting with the idea of using FT8 to chat, but what if I told you that there's a better way?

Written by John WB2OSZ, named after a canine that became extinct 9,500 years ago, "direwolf", is software that implements an expensive piece of 1980's hardware, a TNC, that runs just fine on a $5 Raspberry pi. It's been around for over a decade, the oldest date I can find is March 2013 though undated versions before that exist.

It's an example of a so-called software-modem, simple to get started, and it implements the essential pieces of packet radio. It's currently running connected to my radio and I can see packets of information scrolling past. In this case I'm tuned to the local APRS, or Automatic Packet Reporting System frequency of 145.175 MHz.

It's the same information that you can see if you point your web browser at aprs.fi

While that's great, it's just the beginning. Tune to another 2m or 70cm frequency and you can use it to connect to a BBS being run by a local amateur, or, you can tune to a HF frequency and connect to one run somewhere else.

Direwolf also supports a technology called KISS, Keep It Simple Stupid, yes really, developed by Brian WB6RQN, Phil KA9Q, Mike K3MC and others. KISS allows you to connect a modem, like direwolf, to a computer and use technologies like TCP/IP, the primary language of the internet, across a radio link, any radio link.

Let me say that again with different words. You can use your HF radio to browse the internet. No proprietary modes in sight, weak signal, error correction included, all open source, all free, all ready to go.

While we're singing its praises, direwolf can also act as an iGate, an interface between radio and services like aprs.fi, a digipeter that receives and re-transmits APRS data and plenty more.

It gets better.

What if you wanted to use something like RTTY, PSK31, Olivia or some other mode? You could use "fldigi" instead of direwolf since it too supports KISS.

To be fair, there are lots of moving parts here and I've glossed over plenty. This isn't intended to discuss precisely how to do this, rather that it's possible at all and has been for quite some time.

I can't wait to attempt to browse the internet using my radio, for nothing other than the thrill of attempting it.

I wonder if I can do this with Morse Code as the underlying protocol. Only one way to find out.
