I have recently become more aware of and generally interested in electronics and amateur radio, and it got me thinking. What advantage, if any, would there be to having amateur radio experience, over a simple disaster crank radio/flashlight, in the event of a major natural disaster or some other emergency that leads to a longer delay in power being restored? For the sake of argument, let’s assume you have a generator or battery bank to supply your own electricity.
What are you talking about?
HAM radio operators can talk between continents.
CB has nowhere near enough power to do that.
They also have two vastly different usecases.
CB can be used as a dispatch system for cars and trucks, great for coordination of local vehicles.
HAM would be used for relaying data between physical sites, data about status of people, food, housing, water, power.
Both are important, but HAM is more important.
See my other comment, if the stated purpose is to help your community during a power outage or natural disaster, and you’re the only one in your community with power, it doesn’t do much good.
Calling Texas over HAM doesn’t help communicate and coordinate local efforts.
You can only communicate, locally, to other people who have power.
A CB radio lets you talk to anyone with a CB in their vehicle.
Umm… Where are you getting the idea that a CB can be powered by a vehicle, but a ham radio can’t?
OP is talking about batteries and generators meaning a fixed installation, not a mobile one.
You realize that if you call Texas you can also reach someone locally.
A lot of ham equipment can be run off of batteries, generators, solar power, vehicles, etc. for some hams, that’s even a big part of what interests them- going out into the woods or other remote areas to see who they can make contact with from there.
There are official policies in place for ham radio operators to work with local emergency services. ARES & RACES, for example. I know that my $20 baofeng can even be used directly on some emergency frequencies (depending on what sort of radio system they’re using)
As an example of how it might work
If cell and landline phones are inoperable, you might instead have volunteer ham operators posted at various places around the community- probably schools, government buildings, hospitals, recreation centers, etc. places where people might gather, where aide is being distributed, that might have backup generators, etc.
And you also have them or professional radio operators at police/fire/ambulance stations, 911 dispatch centers.
Someone having an emergency would let the local ham operator know and have them relay the info to the station or dispatch center so they could send help
Less efficient than just calling 911 of course, but better than nothing.
I work in a 911 dispatch center, we have a small room full of ham equipment that we can send out or use for these sorts of situations (luckily we’re not in an area prone to major natural disasters, so it’s rare that we ever have to use it if ever, but we’re prepared if it ever happens)
You can only reach someone locally if they also happen to have power, which as noted, is the problem scenario here.
If everyone around you is powerless, and you have power, it doesn’t really matter if you can transmit or not, nobody locally can hear you.
Did you miss where I addressed that by pointing out how generators, batteries, solar panels, and vehicle mounted radios exist?
If you are the one with power in your local community with power, then HAM is far, far, far more important than CB.
If your local community is out of power then you won’t really have many more people in the local area to communicate with, but with HAM you can reach across vast distances and manage way more resources between different local communities to deal with the crisis.
In a local community, radio comms is a nice to have, over vast distances it is critical.
When the problems are local, not over long distances, it’s more important having a local connection.
For example, during Hurricane Katrina, police band radio was being broadcast over the internet. The most heartbreaking call I personally heard from the stadium was an officer begging “Does anyone know how to deliver a baby?”
Getting that message out over long distances did not help the situation. Getting it out locally DID.
Just because a signal may have a long range, doesn’t mean it can’t be intercepted locally.
No, it would depend on someone else locally having a similar rig and there are far more people with CB radios than HAM radios.

The numbers of Amateur Radio Operators (not just in the US) are declining.
The influence of the ARRL will inevitably decline as a result of disgust at the Board of Directors infighting and dues (subscription) price increases.
The use of voice VHF / UHF repeaters are significantly reduced, year to year.
Emergency Communications has subtly become less of a justification for Amateur Radio. Simultaneously …
In the 2020s and beyond, First Responders have more, and more reliable communications options than ever before.
Communications infrastructure available to most individuals has become more concentrated and fragile.
COVID-19 and other factors have impacted many Amateur Radio club meetings and other reasons for Amateur Radio in-person events.
The potential audience of younger folks to become new Amateur Radio Operators just don’t find “talking to strangers” or “operating on shortwave” to be compelling reasons to become Amateur Radio Operators.
That’s actually false. The supporting arguments you have provided are reasonable, but they ignore the fact that CBs have declined far faster than amateur radio.
CB radio is very low power and limited range. I had a CB in my Jeep for offroading. It wasn’t an ideal installation or an ideal antenna, but it was basically what most people driving a normal vehicle and not really serious about CB-ing would install.
It was good enough for the trail where I was 100 yards from friends but going down the interstate listening to trucks, I was basically limited to trucks I could see within a half mile or so.
With a 2 meter ham radio, the most common band that even beginners can use, and a lot simpler to install than CB, I can talk 20 miles fairly easily, twice that to reach some repeaters in the mountains.
But caling tevas gets you in touch with someone else who can arrange with the rest of the world to get things you need.
