N2QT's write up on this is great http://groups.yahoo.com/group/Elecraft_K3/files/KRX3_IF_Out/
However, I'm wondering if an alternative might be to duplicate the IF JFET circuitry of the main RX and put it on a small perfboard inside the SUBRX. Then feed that output to a jack just like the main RX. Thinking the following components C55,C59,C68, R8,R9,R89, RFC22 and Q10 would be all that is necessary. The Clifton labs buffer/preamp would remain outside of the K3. I'd like to keep as much of the SDR spurious signals out of the K3 as possible.
