Dave,

I don't know the answer, but one guess is that the output of the 
RigExpert may be pre-set for mic level (reduced to about 1/10 of 
soundcard normal output).  The line input of the K3 needs a 'line level' 
signal (about the same as soundcard output).

You can try plugging the RigExpert output into the rear mic jack to test 
if the level is the cause.

73,
Don W3FPR
