Baofeng UV-82 Walkie Talkie 136-174/400-520MHz 2-PTT 5W Portable RadioThe UV-82 series has upped the bar on affordable ham radio technology! Compared to previous BaoFeng products (UV-5R， GT-3， and UV-B Series) the UV-82 comes with a much louder speaker (1 watt)， a much more solid case with larger buttons， and a new chipset and PCB board that outperforms the range， accuracy， and output of the previous BaoFeng chipsets. It is not simply a remake but a new radio from the ground up.
