Staying in touch without the internet? It's possible
In a new step-by-step video tutorial, tech worker Kit explains how to send messages over a mesh network using a LoRa board and Meshcore.
And yes, that's without a mobile network or the internet.
Taking control of your communications infra is especially important for workers in the Netherlands. Because you don't want to be dependent on centralized, commercial platforms, do you?

#LoRa technology allows people to establish an ad-hoc mesh network that supports AES256 encryption absolutely independent of the web. There are two competing approaches, #Meshtastic and #Meshcore. Messages are short. The mesh architecture supports Internet-free communication for fifty miles or so. If you connect to the Internet, you can have secure short message communication worldwide.
Okay. Add #Reticulum to the list.
#Heltec, manufacturer of cheap #ESP32 #LoRa boards describes its two biggests sources of demand, #Meshtastic and #Meshcore users.
Let's see if Reticulum gets traction.

Here's the challenge under FCC rules in the U.S. anyway. No encryption on the 70 cm, 2 m, or HF amateur bands.
You can use ISM bands with power limitations encrypted and unlicensed.
Help me understand RNS.

" [With #Reticulum you can never accidently send anything unencrypted."
With Packet Radio (amateur) you aren't allowed to send encrypted traffic, unless you publish the decryption algorithm...and that includes the keys.
