In this video, I share two key performance differences between a genuine RTL-SDR Blog V3 dongle and an imitation "generic" RTL-SDR dongle:
1. The frequency error of the Blog version was apparently 1 PPM as advertised, whereas the generic version had a frequency error of more like 62 ppm
2. There was a high pitched tone present on the generic version when receiving narrowband FM signals which was not present on the Blog version
Bottom line: Choose a genuine RTL-SDR Blog V3
