[Skimmertalk] Flex and Skimmer : Decoded bandwidth ?

I previously had Skimmer working with an SDR-IQ but lately have been using
a Flex 3000.  I don't think I have been paying enough attention to the
settings until today .  The Flex 3000 gives about 96 Khz of bandwidth in
theory, more like 80 kHz in reality. Plenty for most of my needs, I can
switch to the SDR-IQ if I need 190 Khz. However, I  notice today that if my
Flex is set for 14043.00 on 20M, the lowest frequency CW Skimmer decoded a
CQ call is 14031. , the highest so far is 14055. There may not be a lot of
CQing above 14055 but I would have thought there would be a fair amount of
CQs below 14031. I have my sampling rate set to 96 Khz.  The bandscope in
Cw Skimmer starts at 14031 .  I must be doing something stupid.  To get a
Flex to work with CW Skimmer, the instructions are to use the Sofrock-IF
settings.  I wonder is this is part of the issue.  I would like to decode
CQ over a range wider than 24 Khz.
