The UV-5R is a great little radio for the price. For $65 you can now get a radio that comes with a 3600 Mah Lithium-Ion battery, a charger,and a hand strap. The software is free as a download. The radio, as has already been overstated, is part-90 certified. It will transmit from 136-174 and 400-512 Mhz. (with CHIRP). It is a great little radio, I have 2 of them. That being said, I would NEVER recommend it for any type of comercial use. Fun is fun, serious is serious. This is a fun-time radio and nothing else. For serious work ( PD/FD/EMS/Etc.) I would stick to track proven radios already in use in the field. This is MY opinion!
