generic repeater
I thought about being a “meshtastic pioneer” and in my head that means rebroadcasting on multiple frequency slots just so meshtastic user can connect without me independently having them to tell them what channel and modem preset I’m on. with my research it seems that there isn’t 1 thing I can buy that can work on the entire US(915) band). im curious if anyone would recommend or has installed a radio repeator for meshtastic bands
I don’t think what you’re trying to do is very practical.
For US 915, there are between 52 (SHORT_TURBO) and 208 (LONG_SLOW) frequency slots. Each node has to use the same modem presets as well as the same frequency (you can’t mix and match any of those). Nodes can only operate in one mode and frequency at a time.
So to cover all cases, you’d need:
That’s a total of 988 nodes to cover all, and that’s not even getting into the fact that they’d be talking over each other.
Basically, if you want to be a generic repeater, it’s best to set your custom channels as primary (if you want to have custom channels) and create a LongFast secondary channel. Then manually set your radio frequency to the one used by the default LONG_FAST setting (908.875 MHz).
That’s basically what I do and lets me have my own private channels while also relaying for and being able to make contact with anyone else using the default config.
dang nice to know how many devices are needed. I think that switching channels would cut down on the number of nodes, but idk how to auto switch settings. good to know the default setting because I was gonna revert it back.
i should clarify a generic radio repeater that inst meshtastic but is able to repeat LORA signal

Well, the numbers I gave would be the same since those Meshtastic “modes” are just profiles for different LoRa settings, and the same LoRa Settings + frequency slot still applies (Meshtastic just runs on top of that).
I think what you’re looking for is a dumb signal repeater, but I’m not super knowledgeable of the pros/cons/legality of those for the entire 915 MHz band. You’d be repeating anything in that frequency range, not just LoRa. And those also repeat noise the same as signal. Basically, it could end up making things worse in the long run by introducing noise.
Probably best to just coordinate with or start a community mesh group and settle on a specific frequency and LoRa settings.
