Hi all,
I have just purchased 2 LORA radios that are compatible with Arduino. It uses the 433mhz, and I live in the US. Can someone give me a definitive answer as to if I can use these modules if I live in the US? I have tried to look online for answers, but haven't gotten any clear answer. A clear answer would be appreciated. Thanks! 
The frequency is allowed. Radiating power matters.
