Yes this uses normal ham radio and not LoRa like Meshtastic.
Wouldn't that mean it's unencrypted and anyone listening in could potentially read emails if they catch the transmission
Someone could just setup automatic recording and leave that unmonitered and then just remove the useless data at the end of the day
Depends, but yes if you are in the US it is illegal to encrypt data send that way.
Is it illegal to encrypt radio in the USA?
Not in general, but on the specific open bands that ham radio operates on yes. This was originally a regulation to ensure these bands would stay open for amateur use and not be hogged by commercial providers, but it feels a bit antiquated these days.
Only amateur radio, because it's only designed for experimentation, not for day to day use. It's the same in Australia.
