LoRa might be a more attractive option https://hackaday.com/2022/05/25/long-distance-text-communica...

eventually with APRS (amateur packet radio)

Thanks for the links. Yes it might. In the same time the ADPS has lower requirements to operate: a PC and a USB-flash. LoRa requires specific boards, in some countries it's much easier to buy old PC than to find LoRa boards. And the ADPS can transmit and receive much larger files compared to LoRa.
