I'd love for an IP over Mesh network to become popular. Doing IRC and reinventing a lot of the early internet in a distributed manor would be very fun.

There may be value for this to the public, but it's not the same as Amateur Radio.
A "no commercial traffic but there's no way anyone could verify it" rule wouldn't be very effective.
What would the nightmare scenario look like? Drama? The community gits gud at MIMO, to work around the abuse, and HFDF, to track it down and police it? I'd watch that movie. Hell, I'd play that game, sign me up!
If all else fails, what about new legislation involving cryptographic signatures and bandwidth quotas? What if those spawn a secondary market where people take the HAM test just to rent out their callsign for crypto tokens? Would that be a bad thing or spawn a crazy collectively-owned disintermediation of telcos? Would the world really be such a bad place if instead of paying $60 to ATT I could pay $30 to some teenagers who memorized RF facts long enough to pass a test?
I'd say that HAM can evolve or it can die -- but eventually the people holding it back will literally die and then it will evolve all the same. That's how actual evolution works. You can't stop the future. Still, you can hold it back, and it's unfortunate to see that happening, from a community of techies no less.
Pretty much sums it up. Locally the people who are in charge of the clubs which ultimately advised the government were in their 50s to 90s (yes that's a 9). The people doing anything more interesting than talking on on those channels are all under 40.
Ham radio is meant for experimentation, not (just) talking to your friends. These people remind me of Bell in the 70s forbidding you from connecting anything that's not a phone to the telephone network.
One of the points of amateur radio is experimentation. Right now the old boys clubs that all ham radio organizations have turned into to have decided that packet networking isn't real ham radio and you shouldn't be able to do it on "their" spectrum.
Apart from talking to satellites, packets and encryption are fine there for some reason.

(If you’re not familiar with the UK structure, OfCom is the FCC-like government regulator, while RSGB is the de facto ruling body / club-of-clubs run by amateurs for amateurs.)
Marconi and the other greats in the history of radio were people messing around in an unregulatedish space. The only place you find those kinds of hams anymore is in THz operators who do some crazy shit.
Also, my understanding is that the encryption rule isn't really enforced but still prevents mass abuse. Plus if the entire stream is encrypted then you can always claim to be transmitting random data as a public good for random number generation.
Take your binary message, encrypt it, use a lookup table to encode the bits into common English words, send them in the clear.
>No sir, this is just a random word service which provides random words free on the air.
The actual rule would prohibit this since it prohibits: messages encoded for the purpose of obscuring their meaning
And I think a "random word service" would also violate: nor may an amateur station transmit one-way communications except as specifically provided in these rules
This restriction comes up quite a lot in discussions about "modernizing" ham radio. I predict that if encryption was universally allowed, the ham bands would quickly become saturated with encrypted channels as hobbyists and not-hobbyists start using the bands for their personal communications networks.
The two main problems with allowing encryption are that 1. The HF bands often have worldwide propagation with very low power levels, which turns local interference into national or international interference, and 2. With encrypted communications it would be impossible to enforce other amateur radio laws, such as forbidding commercial uses.
I think that allowing encryption on dedicated slices of the UHF bands would be a more realistic approach.
Signals in copper travel at about 0.7C, while radio in air travels at ~1.0C. (Light in fibre optic cable is also about 0.7C).
1. HFT firms have definitely tried to perform HFT communication on HF bands before, see [1].
2. IIRC there have been some undecipherable transmissions in ham HF bands that were suspected to be associated with HFT, but I can't find a source right now.
3. While you don't have any additional latency from routers and serialization delays in the path across the pond, you need to keep in mind that long-range HF communications rely on bouncing the signal on the F1/F2 layers of the ionosphere (an atmospheric layer with lots of charged particles/ions that act as a mirror to HF signals). If you're comparing HF transmission with a hypothetical straight-line fiber connection (assuming it the propagation speed in the fiber is comparable to the atmospheric propagation speed [2]), the fiber connection would win.
Additionally, bandwidth is an extremely scarce resource in HF bands (compared to cellular networks or other common VHF/UHF systems). There's a reason people still use CW (morse code) or even PSK31 [3] instead of SSB (voice) [4] in HF bands: You need around 500 Hz for CW signals, around 3000 Hz for SSB signals. PSK31 only needs 31.25 Hz. My point is: While you might beat latency of fiber connections and routers along the path, the throughput is going to be quite low for HF transmission.
[1] https://spectrum.ieee.org/wall-street-tries-shortwave-radio-...
[2] Since you mentioned copper: Copper can be quite a bit slower than fiber depending on cable type, since the propagation speed of signals in copper cables depends on the velocity factor. Wikipedia gives a few examples: https://en.wikipedia.org/wiki/Velocity_factor
[3] PSK31 stands for Phase Shift Keying at 31 Bd. The short explanation is that PSK31 is a bandwidth-optimized text transmission mode.
[4] SSB stands for Single Sideband. The short explanation is that SSB is a bandwidth-optimized AM voice mode.
Bloomberg picked it up as well if you are into that side of things - https://web.archive.org/web/20180625133148/https://www.bloom...
There are some individuals apart of groups who would definitely use encryption on the ham bands as a means to have communications taking place that are not allowed by the rules. The biggest one would be communications with a connection to politics. Met plenty of these types who are jealous of the ham band and scorn the rules because of that, so they keep themselves on CB and FMRS.
Also like you mentioned, it is now free radio space for commercial entities to try to use.
While a massive restriction, you can prevent interference (but not eavesdropping!) by signing your payloads. Maybe it's because ham radio and privacy aware people is a venn diagram with a lot of overlap, but it feels like perfect being the enemy of good.
Modification of those messages isn't something I'm worried about. It's not perfectionism, it's a different use case.
And if that's the use case you want, you should look elsewhere.... At least, that's what the people leading the ham radio community and arrl say.
I'm not sure I agree with that, but I'm not sure I disagree either. I certainly think the community aspect is less important today due to the internet, but it's probably still crucial.
And that's what people are doing, which is (I'd guess) why we're commenting on an article about the uncertain future of HAM radio.
Also, that's going to change the community, but it won't erase it. Just like the HN community isn't hampered by the presence of encryption.
When I flung packets across the bay with a friend, we used cell phones to figure out antenna positioning and alignment. violating the spirit of the intention of these rules, imo, but hard to say
Makes sense. And my cohort comes from an era when we can talk to anyone, anywhere, but the channels are controlled and watched. The ability to communicate isn't special anymore, but the ability to communicate independently and privately is. We don't want communication, we want known-good (dare I say, safe?) communication channels.
Do you think that ham radio couldn't be? Or isn't? What you really want is privacy, authz/authn concerns, and decentralization, it sounds like. And TCP/IP is about as useful as a "PHY" layer for your application as is ham radio.
Plus, solutions like what you're describing require a relative ease of use - unless you only want to talk to the 17 other people in your geographical area who have similar technical backgrounds.
And that's just the beginning, before people put in the effort to make it more accessible.
TCP/IP isn't the point, it's the encryption that lets me send encrypted, secure emails to my friends over a network that only wideband jamming or a natural disaster can take down.
We could have a leaderless IRC server, leaderless peer discovery and routing, IP/DNS controlled by consensus.
My question is whether this kind of regulated openness is more worthy of the spectrum assigned to hams than some alternative scheme might be. It's certainly not a very efficient use of spectrum.
Maybe on paper. Where I live it seems to be about old grouchy white guys gatekeeping and LARPing that they would be of any value in a natural disaster.
You can still experiment with and build an encrypted mesh network, but you need different licenses to do so.
Lora and other chirp based protocols are incredibly cool, and I've been playing with them
Lack of bandwidth / capacity to reach any meaningful speed, scale, reliability etc? Or just no demand given how effective copper / wifi / 5g is?
Or perhaps the 'hobby' really is dead and there just are not the tinkerers there once were.
The tinkerers are there, but encryption is a must-have. If HAM can't make that work, it's likely to die.

It’s not growing like the Internet, but there isn’t space like the Internet. It’s fixed real estate that can only have so many people on at one time. If you cruise the HF bands in the evening there’s lots of chatter going on, there’s no room for 1000 times as many people.
Yes it could grow faster, yes it could be much much much more welcoming to new people. The industry could support it with cheaper hardware and technology that allows for more tinkering. But if we want make wholesale changes to the regulations, like allowing encryption, it’s going to have to be very well thought out.
I'm all for working out a really good way to allow encryption. But it sure seems like the pervasive reaction to encryption is just resistance; and that makes me pessimistic.
Sure it will help the park appeal to a broader community and drive up visibility and maybe increase overall revenue...but...ugh.
It works, but...ugh.
The pagers used to be extremely valuable...before better tech was invented. Very few people have a use for the outdated tech anymore. Cell phones let us do far more.
I think there is another agenda: There has always been political pressure to open the ham bands for commercial use. And the one thing that has kept the commercials out is being able to inspect their packets, eg the ban on encryption.
It seems that the push for encryption is a barely hidden campaign by commercial entities.
I imagine that prospect is frightening to a lot of 3-letter agencies.
> There is absolutely no need for encryption to get mesh working.
The internet learned the hard way that encryption is very important, even for casual use. I'm not sending emails -- even, especially, to my friends -- that aren't encrypted.
With the tsunamis, the impending climate collapse and social unrest this should be seen as a need rather than a hobby.
Governments allocated huge chunks of the spectrum for commercial use (and pocketed lobby money) while keeping HAM radio unusable and public use spectrum tiny.
I don't get it. Why would encrypted transmissions be illegal? Doesn't that make local wireless networks illegal?
Always thought that was weird. Cryptography is used all over the internet today yet it it's illegal to encrypt radio transmissions.
While encryption itself is old, its widespread civilian use is relatively recent. There was a time when one could easily pick up receivers to listen into everything from telephone conversations (cordless and cellular), to commercial bands, to the police. Encryption was largely seen as a thing used by the military and intelligence organizations.
There were other reasons for encryption being of limited use. The cost of hardware to encrypt (and decrypt) signals was a factor. The relatively limited role of radio communications due to reliability also played a role. While most of us are only familiar with the end-user facing aspects of computers, the digital revolution played a more important role in communications. It has changed everything from how we share the spectrum to making communications more reliable. It has also opened up higher frequency bands in a cost effective manner. While enabling new applications, many of which involve more the transmission of more sensitive information, it has also made it easier to intercept communications and enabled the bulk collection of data. In other words, we view encryption as a necessity today when we didn't in the past because it is a necessity today when it wasn't in the past.
That being said, I don't think that encryption is necessary for most aspects of amateur radio.
One key differentiator: bandwidth is fundamentally limited in radio.
I think a lot of the new applications of digital modes would avoid conflict by starting off up in the 5 to 10 GHz range and work its way down.
There is nigh on constant pressure from government regulators to take back the spectrum. One of the best political arguments the Hams have for maintaining amateur radio is that it is a common public space, like a park, or a town square.
The worry is that if encryption were commonplace then you end up with a public park filled with anonymous men in hooded sweatshirts and ski masks, whispering to each other. The park gets closed.
It’s not illegal per se. You must have a license (and therefore a callsign, your identity) to operate legally, and you lose your license if you are caught using encryption.
People keep repeating that, but it's not actually true. There are no bands available for long range (50-100 miles between hops), decentralized, encrypted, mesh networks that are cheap enough for random people to connect to.
You're probably thinking of random wifi meshnets that only work in densely populated cities. That's very different, and the limitations of those networks is exactly why HAM radio meshnets are so attractive.
Edit: or in reverse, what kind of current ham radio use would you want to use more openly? Maybe I'm misunderstanding your scenario.
Edit2: E.g. the closest thing maybe is hamnet. Which is literally IP networking, unencrypted, on modified Ubiquiti or Mikrotik WLAN gear so it uses ham bands right next to its usual frequencies and more power. As soon as you take the amateur radio restrictions out, it's just long-distance wifi links, which already have a clear space what they are regulations-wise, the regulations just don't permit as much for it.
I'm not a radio guy. But feels like if the mesh network became popular it could get clogged.
Most of the HF ham bands have kilohertz of bandwidth. These are the bands where you'll get propagation over the horizon. The better ham digital modes get ones of kilobits of data in good conditions. To get that sort of throughput you need good antennas on both ends and a fair amount of output power.
It's enough power to give someone bad RF burns and antennas large enough to require sturdy masts. The antennas alone will violate most HOAs. The output power requires some knowledge to be safe.
None of the equipment required for HF is cheap or easy that some rando can throw some up to participate in a mesh network.
Encryption on amateur bands is a non-starter. There's no practical difference between your fantasy encrypted HF mesh network and RF noise. That means there's no practical difference between you using such a network to chat with your buddies, businesses flooding the air with commercial traffic, and noise.
HF can affect huge areas due to propagation. If a business uses a HF mesh network for commercial traffic in the next town over from you, they can basically shut out you from using it. It also potentially shut me out in the next state over.
HF mesh networking is not very practical to begin with and the tiny slice of HF hams have it's just laughable.
Imagine people within a half million square mile area trying to share enough bandwidth to eek out 5 tweets per second.
Such things already exist (Winlink, SailMail, etc) but you don't like them because there's no encryption and they don't have buzzwords like mesh in the names.
You seem to think encrypted transmissions on ham bands will let you play secret agent. All encryption will do is increase the noise floor on HF to the point its unusable by anyone. HF is already a noisy band but a bunch of people playing secret agent will swamp the bands over huge areas.
I believe you are even allowed to use digital signatures, you just can’t encrypt the payloads. I would argue a digital signature is not “messages encoded for the purpose of obscuring their meaning”
So yeah, you can’t use it as your ISP but you can do quite a lot. The problem is finding enough other people in your area to set up nodes.
Regarding mesh networking, you don't have to have encryption to do that. It could still be very interesting, you just have to know that people can inspect your transmissions. If they didn't allow this restriction, I imagine the system would just be overrun.
I think it would be very popular even with just a clear text internet over ham radio. You would probably even need additional restrictions to keep it from being overrun - like maybe only dedicated "ham radio internet" web sites would be allowed, as opposed to being just access to the (standard) internet.
You can't have traffic that is ssl, ssh, or any other encrypted protocol. Stop and think how useful a network you can have without that, no emails, no websites, no authenticated connections between computers.
The only things we have left are http, telnet and anonymous ftp.
Welcome to the 80s Arpanet, but anyone can modify your packets undetectably.
The problem still is that you have no way to authenticate on any layer above the hardware.
Ham radio as is is stuck in the 1960s which given the age of the people on it isn't really surprising.
However, signed packets do not violate the HAM rules, and is pretty common. People controlling systems (like repeaters) can ssh to them, with encryption disabled (there are patches), but still using signatures to avoid worries about packet modifications.
js8call for instance can do "mesh" networking, but the bandwidth is a few 10s of bytes per minute. But you can send messages through multiple hops to allow things like getting messages through to people you can't directly contact.
The main reason for encryption is to allow for self regulation, and if you can't self regulate if the traffic is encrypted.
does this include caesar-shifted morse?
You have a very narrow view of the hobby.
There's nothing stopping experimentation with HF packet today, but you have to be realistic about what you can accomplish.
