The problem with lora (and APRS over satellite... well, even ground APRS) is, that the bandwidth is very limited and usually only for "one person at a time", so while meshtastic/meshcore might be fine for tens of stations and a few users chatting, once those numbers get higher, the routing/signalization uses up most of the bandwidth, and many people sending messages at the same time makes the whole system very unreliable.

APRS is a bit better, because it requires ham licences and (usually) a bit more expensive equipment, but with "SmartBeaconing" and just a few hams, you get collisions (multiple people transmitting at the same time, effectively jamming eachother).

Reddit is usually full of preppers and other idiots buying these cheap chinese radios, usually without any knowledge and licences (that are needed to use them), and in turn they know nothing about actual use of those devices.... simplex range in urban environment is measured in hundreds of meters or maybe one or two large buildings between radioss, and repeaters will be in use by actual emergency servics and not really usable for any kind of "private use".

tldr: get a few books, a pack of cards, wait it out, not so long ago being unreachable away from home was the norm, and we managed.

What I don't get about Meshcore is... What's their goal. They seem a commercial venture, their contact email is customers@..... I don't know they're license... I rather use meshtastic.

If I go to https://meshcore.co.uk/about.html, the fact that there is two youtube videos there and not a button that says "Download Docs PDF" shows me exactly how serious they are about "[We] connect people and things, without using the internet"

You could just about squeeze voice down LoRa with a really low-bandwidth codec, as really aggressive codecs can manage < 0.5 kbps. If you want to sacrifice voice quality but use standard codecs, the military MELPe codec has 600 bits/s as one of its standard modes.

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.
