[Elecraft] K3 Sub-receiver use

Correct.

If you decide to bring out an IF signal from the KRX3, keep in mind that 
there is 100 dB to 120 dB isolation between the Main and Sub IF signal 
chains, and this *must* be preserved to prevent crosstalk between the 
receivers.

This really gets nasty if you decide you want to switch between them, 
for example.  High reverse-isolation buffers may also be required for 
such experiments.
