    Understanding signal strength calculation

    I use FA antenna/blue USB dongle on a Pi 3 B+ with ADSBReceiver image, I see a pattern where signal drops from 0 to -30 and it is always around midnight CEST.

    I was wondering how signal strength is measured here? Does this has to do with low traffic during that time?

    If there's no signal in the sky to receive. It is only conceivable the signal level would reflect it.
