[Elecraft] First Contact with KX3 But strange behavior observed

[Doug Person]

The KX3 arrived many weeks ago and just haven't had the time to get it 
assembled and on the air.  I found time at last yesterday and it went 
together in no time.  Very, very easy to assemble.

Once I got it on the air the receiver sounded great and all the controls 
made sense and seemed to work well.  One strange thing thought.  I was 
copying some cw on 30 meters and decided to narrow the bandwidth a bit.  
However, once the bandwidth switched to FL2 the signals disappeared.  I 
don't mean faded or got weaker - they disappeared.  I would assume being 
a purely DSP receiver, I should be able to digitally reduce the 
bandwidth.  I could hear a faint click of a relay but I'm not seeing any 
setting regarding filter setup.  Everything is as shipped. I haven't 
changed any settings.

What am I missing?
