PLEASE remember that you *must* have a high-reverse isolation buffer 
between the K3 IF OUT jack and the Softrock antenna input.  The Softrock 
may have a huge spur at its carrier frequency and its mixer may not 
suppress this adequately.  So there is a potential coupling problem 
(mixer) and radiation problem (shielding).  The IF out of the K3 does 
not have high reverse isolation characteristics, so you need to ensure 
you do not couple a signal at the IF *into* the K3 through this connector.
