Why not use Codec2? It only needs 700 bits per second. That's well within the capabilities of LoRa.

Okay, that is really fucking cool. I thought about doing something similar for web pages. Like your standard web page would be a bit much, probably. But something like a Gemini capsule might very well be able to be transmitted that way. Split the page into chunks, get the number of those chunks, and get the hash of all the chunks together, and start transmitting them with a sequence header, and then each chunk one at a time, and then send the hash at the end as a validation.
