An interesting proposal about how to improve APRS data transmission over LoRa: https://aprs434.github.io/
Ricardo CD2RXU is developing firmware https://twitter.com/richonguzman/status/1671034373230010369
Original project was from Austrian amateurs: https://www.lora-aprs.info/
Bummer, it looks like the i-Gate github page hasn’t been updated in over 2 years. This seems like a promising project. it does look like the original project is more active.
