Incredible value for a Tri-Band Radio.Buy a large battery that comes with the car charger, buy the triband antenna, and buy the usb communication cable.Optionally, take the Technician course for $15, answer most of 35 questions and you can literally talk to the world on a good day.This unit has an FM radio, flashlight and siren built in, plus the programmable channels.I programmed channels to have weather band, local EMT, local Fire, Marine Radio channels 1-20, the Walkie Talkie channels, and downloaded local transmitter stations for Govt and Ham Radio stations near me. It is easier than you would expect. I had no knowledge of how to use this thing and no radio experience when I bought this radio. But if you buy the usb communication cable and the triband antenna, with a little help from youtube, you can download a program called chirp and program your radio to do it all on a rainy afternoon.As a followup, I broke the belt clip 8 months after the original review. I contacted BTECH via their customer email and they sent me a belt clip at not charge within 3 business days. EXCELLENT CUSTOMER SERVICE!!!
