Oops, I need to read more carefully before responding.? If you put the QMX+ in CW mode with wsjt-x receiving, you will see the CW filter bandwidth at a high volume.? This is because wsjt-x normalizes the display for gain across the entire 4kHz bandwidth,? but the QMX+ filter has dramatically reduced the energy outside the filter.? Set the CW passband to 'none', and that will go away.
