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.
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 compare to being able to whip out a handheld radio, tune into a nearby repeater and dial out with EchoLink to check in with my partner when I’m hiking.
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-of-hand and burns down the house.
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 the right tools for the job".
Essentially the difference between being book smart vs. street wise.
Training is critical, but even then you can still fail, which is why layers of backups are great.
For a lot of us, skill might never be as reliable as other layers, but it's generally different from other layers making it less likely to fail at the same time because of the same cause.
Crew Resource Management has a lot of great insights.
Just to clarify: the law in the US (47 CFR § 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.
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 meters, which might not be enough to hit an area repeater except in ideal conditions.
Either way, having the knowledge and practice going into an emergency is much more helpful than just the equipment!
