If I make a recording from satellite band, Airspy , 5 MHz bandwidth and I open the recording after that the navigator only shows a bright yellow page where the contrast / colour bar in the consolem menu has no influence at the contrast of the navigator bitmap.
If I open previous recordings the navigator shows the signals nicely.
the two latest recordings where this happend where recorded as 32 bits weak signal. I am now recording in 16 bit mode to test.
My 16 bit recording show signals in the waterfall and the contrast can be adjusted again.
I guess this is an unexpected future :-)
