I just wired $1500 to Unication (radio, battery, charger, antenna, programming cable, bluetooth, international shipping) for my U3, so that's out of the way. Self programmable for Phase 1 and 2 trunking with no system keys needed, meaning if your an idiot, you can affiliate and get your warrantyless U3 bricked really fast. The radio does have receive only modes, and Unication offered to program it for me if i wanted, ust had to send a list of systems and talkgroups. I am crossing my fingers I am not hit with some ridiculous Trump import tariff when it hits the US. :-O
