Hi Spiros,
Looks fine now. I bet your Kenwood RX also treats CW as "LSB"
(inverted audio frequencies) .. in USB it is easier to adjust the
scale.
You could turn up the brightness of the spectrogram display, or
turn down the contrast a bit, so that the "natural" noise floor
gets through (just a tiny bit) like a slightly snowy screen.
Totally black background means there is a threshold which doesn't
let very weak signals get through.
All the best,
Wolf .
