Anyone doing a PPM offset for their RTLSDR?

I never bothered to set ppm , but did bother to set gain, and tweaking gain definitely improves reception.

ADS-B signals are so wide anyway that it doesn’t really matter if the dongle frequency is a bit off. Even 100ppm is only around 100kHz error, the signals are maybe 2MHz wide.
