This is cool! I have been really enjoying using Meshtastic and LoRa lately. It feels like a blessed relief from the toxic swamp of the regular internet. I love pinging stupid radio messages across the bay without depending on any third-party infrastructure. Maybe in addition to the literal rubble of a life threatening disaster we can use tools like this to dig ourselves out from the psychological rubble of the information superfund site we have built for ourselves
You got anyone pinging you back? I can't convince any of my friends to care.
I'm this way with trying to convince random people on the internet to chat over fldigi on HF frequencies. Hellschriber is awesome.
TIL!

Fldigi is a free and open-source program which allows an ordinary computer's sound card to be used as a simple two-way data modem. The software is mostly used by amateur radio operators who connect the microphone and headphone connections of an amateur radio SSB or FM transceiver to the computer's headphone and microphone connections, respectively. This interconnection creates a "sound card defined radio" whose available bandwidth is limited by the sound card's sample rate and the external radio's bandwidth. Such communications are normally done on the shortwave amateur radio bands in modes such as PSK31, MFSK, RTTY, Olivia, and CW. Increasingly, the software is also being used for data on VHF and UHF frequencies using faster modes such as 8-PSK. Using this software, it is possible for amateur radio operators to communicate worldwide while using only a few watts of RF power.

Another interesting protocol that supports LoRa is Reticulum, which uses an announce based system for bandwidth efficiency instead of Meshtastic's flood based routing.
TIL thanks for sharing those!
