If you have set `READSB_GAIN=autogain`, then the system will take signal strength measurements to determine the optimal gain. The AutoGain functionality is based on a (slightly) modified version of [Wiedehopf's AutoGain](https://github.com/wiedehopf/autogain). AutoGain will only work with `rtlsdr` style receivers.

Note that AutoGain is not related to the SDR's AGC setting (controlled with the `READSB_RTLSDR_ENABLE_AGC` variable). We do not recommend enabling AGC for Ultrafeeder or any other ADS-B decoder.
