Adjusting background waterfall intensity of OpenHPSDR

[khei...@sbcglobal.net]

I'm up and running on HPSDR, WSJT-X, and fldigi, thanks to Joe, LB1HI.  I would like to reduce the background intensity of the OpenHPDSR watefall display, but am unable to find the control.

It is probably very obvious.  Could someone point me in the right direction?

Thanks,

Karl - W5QJ

Hi Karl, 
the background intensity  and contrast to signal   are  influence   among other things by FFT Length and type of detector.

Further settings are the high  and low levels of  graphical imaging.

The fields marked in color correspond to the above-mentioned functions.

Thank you Joe.  I made some adjustments per your screencap, and it helped.
