    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.

        Licensing means nothing in an emergency situation. I never understand why it is even mentioned in these arguments. In fact, even if the world isn’t ending, you can ALWAYS use a ham radio in an emergency with or without a license (defined by the FCC as immediate dangers to life or property).

        More importantly, there are at least an order of magnitude more ham radios out there than mesh devices. It isn’t even close. If the world ends, find a ham radio. Ideally you will know what to do with it when the time comes.

        I wish this energy was just put towards promoting ham, tbh.

        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.

          Yeah… if I am trying to reach people tens of miles away during The Apocalypse, I am already dead.

          Anyone who is within range to be helpful (or… not) would generally be within signal range of a handheld.

            HF handhelds do exist. Do they have the range of a dedicated HF rig? No. Better than a Baofeng? Yes, and they’re about $10 more.

            What about after surviving the initial disaster? During the rebuilding? Or the ongoing survival?

            Long-distance radios are useful as hell in stuff like The Last of Us.

          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 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.

            Out of curiosity: where do you live where listening on ham requires a license?

            In the US and other countries I am aware of, listening is allowed without a license (how would one even enforce such a thing?). In fact, you can even transmit on a ham radio in the US without a license provided there is an immediate risk to life or property.

      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.

            Starlink and the number of satellites we’ve got up there could absolutely cause a chain reaction if a few too many were destroyed.

          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.
