it seems like an echo or reverb effect of some kind. If I unplug the one of the audio into connections into the SDR and tap, it's like I can hear the taps echoing on whatever frequency where the interference appears.? Thus, I've been trying to see if there's some sort of audio processing enabled somewhere in the audio software,
Jon,
This seems like you have a microphone active?
Or, I wonder if you have "Stereo Mix" or, "Listen to this Device" set in Sound Properties or somewhere. This gives an echo effect.
It will not change with SDR software, certainly there is no way to make HDSDR produce this effect.
