QSSTV  9.4
Spectrum and Waterfall Display

Note: the settings Max dB, Range and AVG do not influence in any way the sensitivity of the reception in SSTV or DRM.

Max dB:

  • defines the audio level at the top of the spectrum display


  • defines the dynamic range in dB to display


  • this is the integration factor to smooth the spectrum display. Values are between 0.6 and 1 (0.88 is a good value).
