When I first got my Tech, I made my first VHF contact with that exact set up. I think I was about 15 miles from the repeater. With a good, properly mounted antenna, you should be able to get 5 or 6 miles even in suburban-ish areas. I had trouble with the quality of the wire going to the back of the mic plug and the sma coax. Repaired and replaced multiple times. There are better ways to spend your money. Are you asking if the radio is certified for GMRS? No, its not Part 95 GMRS certified. Unless I am confused, there is no Part 97 certification. Hams can build whatever they want, only have to use them within their licensure.
