Yes, I would check the crystal configuration.  When I originally built 
mine, I left the FL1 slot open for future AM or FM filter and put my 
2.8KHz filter in FL2. At some point I also noticed I had no audio and 
this is because the width knob was turned wider than 2.8 so the K3 was 
trying to use a filter which was not installed.
