Got this GT-3 two from radioddity weeks ago. just made a simple comparison with baofeng uv 5R Frequency-Modulated Receiver Chip GT-3:RDA5802N UV-5R:RDA2802E The RDA5802N has a powerful low-IF digital audio processor, this make it have optimum sound quality with varying reception conditions
Power Amplifier IC GT-3:UTC TDA2822L UV-5R:UTC TDA2822F
LED Flashlight GT-3:Pro-LED (straw-hat LED) UV-5R:common LED flashlight
If you guys want read a detailed review, I suggest the youtube review of Baofeng GT-3 and the reviews from eham. those are both good reviews
