Thank you for the information. The code works perfectly. I have my ham radio license so I am going to output the audio to a handheld vhf radio and transmit my license with the data. The LoRa telemetry system is a good idea but I don’t see how even with a high gain antenna, you can get 250-400 km with 10 mW. It is difficult for me to get 2 km with a 100 mW HC-12. But I will definitely look into that. The library I used is bellow.
