Andy, Turn your waterfall gain down (top left slider) and it will clean it up mostly. I have a +20 dB SNR file and it is awful looking until you turn the gain of the waterfall down.
This has nothing to do with decoding, simply a display issue of limited dynamic range. 73, N0AN Hasan On Mon, Jul 22, 2024 at 1:21 PM Andy Durbin via wsjt-devel < wsjt-devel@lists.sourceforge.net> wrote: > I'm decoding K8R on 18.090 with S/N varying beween +6 and +9.
