I played a bit with trace smoothing again tonight. First image, is there a signal there? Second image, ye! I already knew it was there but this was testing with a weaker signal tonight. It is a digital subcarrier on a local FM broadcaster. Of course it is not a very accurate representation of the signal but it does show that there is something.
Many thanks to Erik and Cathy for this wonderful software!

What I can see in your 1st image is the scanraw floating point to 16-bit (2-byte) integer compression showing itself (limited dB resolution).
The only way to improve that would be to go to a 24-bit (3-byte) scanraw integer value.
