OK but kind of outdated and incomplete. Meshcore is largely competing with Meshtastic nowadays: https://meshcore.co.uk/

To remember: LoRa only permits small text messages. Don't even think about images, voice nor binary files (I mean it).

Another option is APRS using satellite connections through a cheap chinese walkie-talkie (Quangsheng UV-K5) for 20 euros to send text messages.

Huh. Hadn’t heard of Meshcore before. Thanks for that. It sounds more organized than Meshtastic. Seems more polished, but also a bit more opaque (from my cursory examination). That may just be, because it’s not had as much time to get established. It has all the open credentials.

From her article:

> Their answer was both depressing and freeing: “You can’t. All you can do is be prepared with tools and a plan for when the crisis arrives. That’s when the organization will listen.”

That is so sad, but also, so true.

I was fortunate to have worked for a company that is over 100 years old, and that had weathered a couple of wars, depression, recession, market disruption, etc.

They were about as open to disaster planning as anyone, but they could also be head-in-the-sand knuckleheads. The biggest thing was the company had a fiscal and cultural conservative bent; quite unusual in the tech industry, these days.

Anyone that has managed a DR system, knows how difficult it is to get support. Disaster Recovery is expensive, resource-intensive, and difficult to test. It is also stuff people don’t want to think about. Sort of like insurance.

My suggestion as someone preparing for this kind of stuff since quite a while:

+ Quangsheng UV-K5 + Android phone with 3.5 mm audio jack + APRSdroid installed

Forget about LoRa, that is basically a toy. It is far more useful to have a functioning walkie talkie capable of talking with satellites and other stations at 50 kilometers of range.

The issue with satellite stuff, is that it’s pretty sensitive to active attack. It will be available for things like natural disasters, but not necessarily for war.

In either case, jamming is a possibility.

That is inaccurate. You will NOT be able to jam a satellite outside local areas, the amount of power to do is monstrous and likely to cause cancer for anyone around.

In a real scenario these things work. Please don't fall into "what if's" which are exotic and confused as things bigger than what they are.

Well, from the comments, here, this sounds like a passionate topic, for folks.

I've always been interested in helping folks that help folks.

I started looking at Meshtastic, some years ago, but found the ecosystem to be a bit overly-complex, as is often the case, with "Swiss Army Knife" approaches.
