Plus, I understand that the SL USB sound card is not stereo, and you
need that to use the I/Q interface from the KX3

I believe the question was about using an interface box (with
integral soundcard) for digital modes. That application does not
need a great soundcard or a wide frequency response.
Those wanting a panadapter display using the I and Q outputs from
the KX3, then a good quality soundcard is a real benefit, not only
in bandwidth, but in the noise floor of the soundcard.
For digital modes, the headphone output and the mic input are used,
and they are not wide range (limited to about 3 kHz). The I/Q
outputs have a much greater range.

Most don't care about freq response.....i guess they dont expect much when
they use hrd or dm780 or nap3 etc.
