What makes voice over LoRa illegal?
Nothing... But with this device the voice part isn't going over LoRa. It's going over a 50mW 470MHz to 520MHz (their claim) Thing is FRS is actually 462 and 467MHz... so.. could be a mistake or they could actually be not using FRS frequencies at all.
Additionally they don't appear to have any FCC approvals which would also make it illegal.
So... Misinformation, low power, wrong frequencies, bogus range claims, bogus audio quality claims and no FCC approval is a bit of an issue.
Add to that the Dev posting out on Reddit and then getting hostile when people ask questions. Not ideal.
Sounds like he's referring to the frequency it's operating at, but I honestly don't know enough about that kind of stuff
