>Anyway, the "noise/distortion" is still there coming out of the headphone socket.
Berni, this is a technical group and as such we need hard data and not subjective descriptions of what you hear coming out of the headphone jack. I don't doubt that you are hearing something. There is very little I can do with your description however. Please download spectrum analysis software such as Spectrum Laboratory which will give you a way to actually show us some hard data. This is freeware but very capable and will allow you to show us something real. The HRD DM780 is a great tool but it isn't designed to analyze harmonic distortion as you can't measure signal amplitude levels. Here is the download link for spectrum labs. http://freenet-homepage.de/dl4yhf/spectra1.html#download Also, you need to run the input to your sound card from your headphone out jack and not line out if you want to discuss artifacts that you are hearing. If you want to discuss artifacts you are seeing on a waterfall for data modes then run the input to your sound card from the line out. So far your discussion is about what you are hearing but your description of waterfall effects is with line out. These are apples and oranges.
