       | So very true. Ham radio operators, AIUI, played a critical role
       | with emergency communications in the Western NC area in the
       | aftermath of Helene. I believe there were some instances where
       | local PSAP's / dispatch centers were knocked completely offline
       | and they had local ham radio operators helping to dispatch
       | fire/ems resources.
       | 
       | The great thing about ham radio, it really is an inexpensive
       | hobby to get started. Now, once you get into it, you can spend
       | just about as much money as you want (or have access to). But a
       | Bao-feng handheld that costs around $40 or so can work the local
       | repeaters on 2m or 70cm and is a fine way to get started, learn
       | the lingo, etc.
       | 
       | I encourage everyone to give it a shot, and join up with a local
       | AUXCOMM group or whatever you have locally. I have to admit, I'm
       | not as active with our local group as I'd like to be, due to
       | competing demands for my time, but I hope to eventually work
       | things out to where I can get more active.

         | 
         | Baofeng makes a $25 radio that works on 2m/70cm and with
         | repeaters. If you live in a place where there are
         | hurricanes/earthquakes, there is no excuse to not have one
         | charged up and ready to go. Getting the basic ham radio license
         | is easy.

           | How does ham compare to meshtastic in a real emergency?
           | Meshtastic has the advantage that it's license free and you
           | don't have to try to convince people to spend days studying
           | for it.
           | 
           | I have a license and a baofeng, but I don't know much of
           | anything practical about emergency communications.

             | Meshtastic is awesome, I have two T-echos. But it doesn't

             | into a nearby repeater and dial out with EchoLink to check
             | in with my partner when I'm hiking.

               | Pre-COVID, our office building in Tokyo organized a
               | disaster-preparation day every year. This was run by the
               | building management team, which politely informed every
               | corporate tenant in the office section that, yes, they
               | would be participating.
               | 
               | Sure, we all knew when the drill would be so we could
               | adjust our schedules, but the actual alarms did sound,
               | and the entire building evacuated, which included
               | climbing down something like fifty flights of stairs with
               | your emergency bag -- mandated by law in Japan -- in-
               | hand, plus (optionally) using a fire extinguisher on a
               | pretend fire after you got outside.
               | 
               | Sure, the extinguishers were just pressurized water, and
               | you were spraying at a metal target, but you still had to
               | pull the pin, squeeze, and aim, and they were at full
               | pressure.
               | 
               | Was a good reminder that it's way better to have your
               | first experience with stuff like a fire extinguisher
               | happen under controlled conditions, as opposed to having
               | to figure things out before your kitchen fire gets out-

               | 
               | Same goes for radio, changing tires on a car with the
               | provided jack, and so on.
               | 
               | Preparedness is 90% "knowing what to do" and 10% "having

               | 
               | Just to clarify: the law in the US (47 CFR SS 97.403)
               | says that you can use amateur radio frequencies without a
               | license, or unlicensed frequencies, for: "essential
               | communication needs in connection with the immediate
               | safety of human life and immediate protection of property
               | when normal communication systems are not available".
               | That's much narrower than just "in an emergency".
               | 
               | And if you try to use ham radio equipment without knowing
               | what you're doing, there's a risk that you'll interfere
               | with other amateur or non-amateur users who are
               | coordinating their own emergency response.

               | This is the correct answer. I have my license and help

               | but the ham radio community has been around for a
               | century, is far better organized and entrenched with
               | various services, etc. There is far more trust and
               | reliability there.
               | 
               | I look at it this way; meshtastic is for fun, but ham
               | radio is for real work where results carry more weight.

               | 
               | Though just buying a Baofeng can lead to similar results,
               | as it's not that amazing at reception. In my testing I've
               | only been able to get a good signal within a few hundred

               | except in ideal conditions.
               | 
               | Either way, having the knowledge and practice going into

         | 
         | It's sort of hard to answer that. In a certain sense, the
         | answer is "talking to other people on the radio". Which taken
         | literally, sounds kinda boring. You can talk to people lots of
         | ways.
         | 
         | That said, what people get out of ham radio varies a lot from
         | person to person. A lot of people are interested in the
         | hardware, and the electronics of building, tuning, and/or
         | repairing radio equipment. Other people focus on "DX'ing" or
         | making contacts from as far away as possible, using the last
         | amount of power as possible. The fun part is all the fiddly
         | details and what not to optimize the situation at hand. You
         | could think of it as being a sort of analogue to "code golf" -
         | trying to squeeze a certain algorithm into the smallest number
         | of lines of code, or the least amount of memory.
         | 
         | Other people are interested more in the "public service" aspect
         | being discussed in TFA. They are interested in being available
         | to help during disasters and other events. Also, just as an
         | FYI, hams do more than just help during disasters or other
         | emergencies. At least here locally, hams often volunteer to
         | help run comms for sporting events like marathons and what-not.
         | 
         | And then you get people who want to experiment with new
         | modulation schemes, or who want to use genetic algorithms to
         | evolve interesting new antenna designs, or who want to bounce
         | signals off the moon, or who want to talk to the ISS, etc. etc.
         | Other people like messing with inter-linking repeaters to see
         | if they can talk to somebody on the other side of the country
         | using a 5 watt handheld, by linking 5 or 6 repeaters (or
         | whatever it takes). Other people interconnect ham radio systems
         | with the Internet, or do digital data transmission over the air
         | using APRS or similar protocols. Other people might use DTMF
         | tones to remotely control some kind of device. Others are maybe
         | into drones and might experiment with strapping a repeater to a
         | drone and seeing what that yields. Some might use ham radio to
         | collect telemetry from their drone (or other device).
         | 
         | So really, "talking to people" is kinda the base of the whole
         | thing, but there's a lot of other aspects of ham that entice
         | people. Me, I do a small amount of random talking with people
         | on the local repeaters (so called "Ragchewing") but my interest
         | is more in the electronics aspect, and the public service
         | aspect. But there's lots of room to experiment and play around
         | with stuff in the ham space.

           | The basic problem with using HF radio is that you need to
           | know most of the things required for a ham license to operate
           | one. Modern HF radios have displays, scanners, lots of
           | features, and are moderately complicated to operate. Even
           | hooking up an antenna requires some understanding of what
           | antennas really do.
           | 
           | Here's a typical modern portable ham radio.[1] (Not a
           | recommendation, just an example) This one does both HF and
           | VHF, so you can reach both SHARES and locals. Here are some
           | simple wire antenna kits.[2] If you have both of those items,
           | and some kind of power (a car battery), you can contact
           | various US emergency services, radio hams, preppers, and
           | whatnot, even if infrastructure is down for hundreds of miles
           | around. A small solar panel to charge the thing would be a
           | good idea. All this is probably about US$1500.
           | 
           | Any isolated town should have something like that, and some
           | people who know how to use it. Town halls, volunteer fire
           | departments, sheriff's offices, etc. are good locations to
           | keep it.
           | 
           | Preppers seem to be more into VHF handhelds such as the
           | Baofeng UV-5R. That's about US$80. Less range, can't reach
           | SHARES, but can reach a few miles, depending on terrain.
           | Useful if you're two miles from the main road.
           | 
           | Here's a prepper view.[3] He uses a Slinky as an antenna.
           | 
           | Once you have the ability to communicate at all, the problem
           | is finding someone useful to talk to in an emergency. There's
           | no addressing, just frequencies. On HF there's so much range
           | that most of the people you can reach are not in a position
           | to do much. The whole point of SHARES is that there are a few
           | frequencies where someone is regularly listening. During a
           | disaster, they're probably dealing with bigger problems than
           | yours, so calling up Homeland Security HQ as an individual
           | may not be helpful for anything not immediately life-
           | threatening.
           | 
           | If you're near a coast, you can usually reach the Coast Guard
           | on a marine VHF channel. They're a first responder set up to
           | take radio calls.[4] If the emergency requires a boat, call
           | them. Marine Channel 16 VHF-FM (156.8 MHz). The Coast Guard
           | gets involved with major floods, they maintain good
           | communications with other emergency services, and they know
           | almost everybody with a boat.
