K3 No signals in Data Mode

[Ed-3]

When I switch my K3 to the data mode I do not hear any signals.  I hear
plenty of PSK in USB on 20 meters and DM780 will decode them when in
USB.  When I switch to Data Mode I just get background noise with what
sounds like a very narrow filter setting.

What are your data filter settings?  Use the K3 Utility ...

Hi Ed,

It's entirely possible that your filter width is not set correctly. The K3 will remember the setting from the last time you used Data Mode. Also there are several sub levels for Data Mode. For PSK you will want to hold the DATA MD button and rotate VFO-B until DATA A is displayed. Then adjust your width knob until the filter width is correct for PSK. I suppose something around 2KHz or greater. Whatever you prefer.

Ed,

Check your DSP filter bandwidth (glance at the icon in the display).  
The default width for DATA A is 400 Hz as I recall, but it should stay
at the settings you last used.  For use with a waterfall display (as in
DM780), you will want to set the width to something like 300 to 2600 Hz.
