If you setup meshtastic for the love of all that is holy reindex your channels so the public channel is 1 instead of 0. Range tests default to 0. The public channel in my area is regularly spammed with range test and is useless for any meaningful "community" communication. Instructions https://youtu.be/egAZP4KKHNo?t=419&si=s9_ML-GWEaP_bz-W This seems like a horrible default setting or configuration. Why public channe…

Has this issue been reported? It seems like an obvious design flaw.

In russia they have limited internet now. something like mestastic is something everyone would need to make sure we could have communication even though someone tried to limit it.

Is russia densely populated enough to be able to make it work? Around me I'm having trouble getting a connection to any other nodes because there isn't a critical mass of other people running mesh nodes and there's a hill between me and the next city

Put one of these onto the hill and you might have more luck: https://de.aliexpress.com/item/1005011893329415.html

You could also use their site planner to plan out optimal placement: https://site.meshtastic.org/

I have 3 permanent gateways within 3 miles of my house (the closest is That means my awful, underpowered and suboptimally placed gw tries to take part in the network - I can't even make it repeat late (prefer other repeaters), so it jusg mostly adds to the noise (and increases power use).

That's with Meshtastic

With Meshcore? I was unable to hear even one transmission, and I love in the densely populated region.

This doesn't really work, maybe as an impromptu off the grid chat platform for a forest walk, provided no one strays too far. Even 0.5W transceivers work better.

Meshtastic doesn’t seem to work well in dense environments. It is known.

In the PNW there are two very successful meshcore meshes, cascadimesh and psmesh. The former stretches all the way from Oregon to BC and the latter focuses more on the sound.

I just switched over to the mesh core version of psmesh and instantly I was able to get chats from folk across the state. With the Meshtastic version I couldn’t see my friends nodes once we left the pub. And I never got a ping back from my tracker the next town over despite futzing with the channel settings for a couple days

I had never heard of this before, then last week I watched a video about it and was hooked. Now I'm seeing it everywhere! Meshtastic and Meshcore are both cool LoRa-based mesh text messaging that operate in an no-license-required band. While this limits your transmit power, it doesn't prohibit encryption - the inverse of most ham radio rules! Some cities have thriving communities of Meshtastic and/or Meshcore. You ca…

So you have the mesh and then what?

Do people communicate to distribute prohibited anti-government propaganda or is it a network of people who otherwise be too shy to talk to each other by other means?

What is the use case?

It runs independently of internet and power. One use case is a group of people in a remote area (hikers, hunters) carrying their own node and being able to communicate via text over several kilometres.

It's not all people trying to skirt the law. It's kind of like HAM radio as a hobby. It's fun technology that lets people do cool automation projects and sure with a mesh connect to other people. Imagine you have a few acres of land and want to turn on sprinklers or something.

A lot of people use it just to chat with friends and family in a fun way.

Of course the preppers and privacy evangelists see it as a means to get ready for living in a hostile environment. Being fair to them, things don't look awesome in the US.

I bet a few criminals use it, but it's still very niche.

I find it weird that the hop limit is 3 bits, wouldn't that limit the effective range a lot? Unless an intermediate node lies and doesn't decrement and retransmits anyway.

To be fair, the hop limit has to die somewhere. It's an intricate balancing act of causing packet storms vs failure to deliver messages.

6 degrees of separation is probably the intended design constraint, assuming there are sufficient nodes to do long range propagation it would work, so 3 bits should be enough in theory. Or passive repeaters as you suggest to go even further. But it seems in practice to be insufficient.

Perhaps this is the reason Reticulum works so well? hop limit of 255, support for any transport mechnism so a fragmented internet is still suitable for long range propagation.

I don't own the hill and there are people living on it, and I don't particularly want to hang up nodes on council property or worse, private property
