Every year I see more on the map. Have a solar node, good fun.
Ever useful? I doubt it, HAM would dominate in a collapse.
In a true emergency? Yes, HAM is the way to go and I need to get around to buying one of those super sketchy Baofengs. In theory you can configure them to use without a license (which is also on the todo list) but it is super easy to tick into the licensed use. How much people will care will mostly depend on whether your local HAM folk are narcs. But, regardless, all bets are off in a true emergency and Baofengs are dirt cheap.
But in a “the internet is out” situation? Or even a “please evacuate in a calm and orderly fashion” for a wildfire or a bad hurricane? That is where meshtastic (et al) shine and it is well worth convincing friends to pick up a t-deck or whatever. Excellent for the “is it out for everyone or just me?” checks. Also useful for letting people know which field can see a cell tower a county or two over for emergency communication or to even coordinate whether you are all gonna head North or South to hang out for (hopefully just) a few days.
And anyone thinking of using any of that for stuff the government don’t want you to: You are an idiot and you need to learn about how insecure all of those are.
You legally need a license for HAM in the US, but there’s nothing really preventing anyone from configuring a radio to licensed frequencies. As for HAMs reporting you, if it’s an emergency the FCC rarely fines anyone if it’s for medical or safety concerns, were any amateurs to even report you. The whole reason for the Tech license for example is just to know laws and rules for operation. It’s damn easy, too. License exam was $25 a few years back, 8 year term. All the questions and answers are avilable online, they just pull (35? I think) from the pool of 400. Most is pretty basic rules of common sense and civility, a few laws. Most tech questions are just converting frequencies and basic math. They don’t require morse anymore (Thank god, or I’d never pass). And if you pass the Tech, you can go right back in for free to try the next exam level. I never use mine, but I do have an HT I keep charged in case of emergencies.
Keep in mind that without working repeaters, the baofeng will only have a range of a few miles on level ground with nothing in the way. If the power goes out, most of the repeaters will go down too. Some have battery backups that may last a few hours to a few days. Depending on where you are, a few may be solar powered, but heavy use will drain the batteries. Some repeaters are also reliant on the internet for linking to increase the coverage area.
What you really want in that case is a portable HF radio and a wire antenna you can string up over a tree branch or a support with a fishing pole. In the daytime, you can use the upper HF bands for long distance communication. That has a range of thousands of miles, but nearby stations won’t be able to hear you if they are beyond line of sight. Since the portable radio doesn’t have much power, you may need to use digital modes to get through. For more local contacts you can use NVIS propagation on the lower HF bands. That has a range of several hundred miles and can even be used to talk to someone on the other side of a mountain. Even 5 watts and an antenna strung 3 feet off the ground can work for voice contacts out to over a hundred miles.
The four repeaters in my area are run by one club. They do the Field Day exercise every year and from what I remember they run them around 150w per repeater. A small jenny could run those fuckers on 15gal a day fairly easily. In a huge emergency, though, you can relay morse on just 5w through 5 or less relaying techs to most of the world without repeaters at all. (1 if you’re lucky, but I’m being fair to real life interference).
You just can’t legally transmit without a license. You can own a ham radio and listen all you want.
Perhaps where you live.
Internet 101: Laws aren’t the same everywhere.
Early evening in the western hemisphere, OP posted a large sum of perfectly native fluency English, so yeah, I’ll assume US or Canada. Can’t have a conversation without making reasonable assumptions. But please, feel free to add to the conversation, where do some of these exceptions exist? Don’t just “um, actually” the conversation, add to it!
yes they are
No wonder they’re insecure with you calling them idiots all the time.
🫣
I’ve been thinking about ordering some but I’m getting some analysis paralysis just looking through the options, any recommendations on a cheap unit I can hand out to some friends, I dunno if I truly need solar, but I guess it’s not a bad option
They sell 2 helteks so you can play around with them for about 50$. Used to be around 30. I have a couple, they do decently well.
HAM will work best for long distance communication but does not have enough capacity to support local short messaging for any major population sizes. Mesh networks scale in bandwidth and will not be overwhelmed as easily if tens of thousands of people suddenly hop on it at the same time.
I think that Starlink covers a lot of disaster scenarios.
Assuming Elon isn’t part of it or doesn’t restrict usage
Starlink and the number of satellites we’ve got up there could absolutely cause a chain reaction if a few too many were destroyed.
Yep its a fun hobby though!
I never could really get ahold of anyone to talk to, most Elmers in my area died. So I just use the license as an emergency line. Talked a few times on my HT, but most HAMs in my area use their cell phones nowadays.
how do i make it go?
Check out the Quickstart: https://rootaccess.org/wiki/Meshtastic/
There are others but this is from a local makerspace and I have personally done this setup. It works well, as long as there is a node in a high place.
Honestly though its a hobby not something that can be relied on unless your whole community gets together. Hope you have fun!
thanks amigo
I guess here the topic is more of insurrections, like what’s happening in Iran right now or how it went on in HK
How fast could a group of 5 people that want to remove all nodes in the area need to do so? Are they all listed on a map with their location?
Mine is on a map, but in a radius of around 10 miles. Close enough to let people know I’m here, but not accurate enough to easily track me down.
That said, if someone wanted to hunt me down, they certainly could triangulate me pretty quickly.
Yeah all they would need is a small RTLSDR and they make them directional for police and such. Its how they get people interfering with police/fire/etc…etc… on different channels. At 1W or lower its going to be a bit hard to find, but anyone determined would be able to triangulate pretty quick.
Is it meshtastic? I’m pleasantly surprised by how much it’s grown around me in just a year
It’s cool yes. But my wonder is if it will be on anyone’s mind when things go south.
In a lawless world, could you trust anyone that said hello back?
I think the point is to keep in contact with friends and family. Maybe it would be used to blast news or alerts in a time of war idk yet, I just ordered some radios a few days ago and I am waiting to get started with it.
Yeah I’m thinking for flooding and generalized chaos but not a direct emergency.
No idea about an appocalypse situation, I don’t have solar so all my gadgets are going down anyway. And not that many solar nodes around me

I’m just here to cheer on a Jitsi link in the wild.
Go Jitsi!
The meshtastic website has a getting started guide that assumes you already have equipment first…which is odd. Is there a reason to go with Bluetooth only? Does it make more sense to get a Bluetooth and WiFi device?
Bluetooth first generally because you use a companion app on your phone to interface with the device and the BLE chip (nrf25840) sips power compared to the esp based wifi chips, that you will likely be supplying with a battery of some sort.
Other timezones
Can someone record? Ill be busy during that time…

Answer: Build another Internet
I just saw a node pop up from my local disaster relief network. I’m not sure if it’s legit…
People who actually have to work and get the bread of the day are not spending money on that. IMHO. Sorry if I sound rude but honestly unless you want to experiment with something that hardly will have any real impact in real life you are just wasting money.
To use these kind of devices you need at least two people using it.
Anyway I guess people spend their money on whatever they want.
Weird, I work and get bread and I’ve got one, and my family members all have one. And most forms of communication need at least two people last I checked.
Is it our primary form of communication? No. But if cell towers go down we’re all within range of sending a text. If I lived in a city I’d definitely have one. It’s a stupid cheap insurance policy. But by all means, depend fully on your cell provider for communication.
Here’s something fun for you: Look up Kessler syndrome. If we were to lose control of our satellite networks for 24 hours, there’s a 30% chance it causes a chain reaction to where we lose the ability to even launch satellites without first cleaning up all the space debris. That time window shrinks with each new launch.
You don’t sound rude, you just sound too defeated to be able to think
They do have a point sadly. I absolutely cant convince any of my friends to get the fuck off of fb messenger and x and Instagram, even though its SO EASY to do so and find better alternatives. They sure as shit would never ever buy something like this.
I do kind of want one. But in my smaller city there’s no way id find another person with one.
Meshtatic radios are very cheap, about $20. It’s one of their main drivers of their popularity.
To use these kind of devices you need at least two people using it.
🤣🤣🤣 A communications device that requires a receiver and a sender??? Oh, how useless!
There’s over 300 meshtastic radios in my area.
My point is, you need two devices and ALSO the knowledge to set up these devices, it was implicit in the comment, some “normal” people even need support to setup WhatsApp do you really think they will use that kind of stuff? $20 is not a lot of money but there are people who can’t afford it anyway. Unless you live in an overpopulated area it will be pretty hard to find someone else using that kind of device, it’s just another hobby like VHF/UHF and CB.
Meshtastic it’s just coping it don’t have a real application and supposing someone make a business and start deploying the system for money the kind of people who are into it will say “greedy fuckers”
Got a link? Also, do we need to dial in to a specific frequency?
There are already users of these though? Meshtastic has plenty of nodes in the US afaik and is perfectly useable. It uses long range radios for communication so you only need a few people in a state to do it for it to work.
TIL: Incels have their own Lemmy instance. Good for you!
Ah looked up the instance and while I didn’t find it I learned it’s not named after “magic the gathering online”
Edit: maybe “magic the gathering online for women” would be a funny way to use the same acronym
Ah done weird conspiracy shit in their comments to
I have no clue what you believe this event is actually about and why people go there.

Yes, listen to this guy - this is totally useless and you should only use
