No, you don't use the large knob to control the KRX3.  You said you 
wanted to use the large knob to tune the transmit frequency while 
listening to your transmit frequency.  In that case you use the 
KRX3 to listen to the (fixed) DX frequency and tune your transmit
frequency with VFO A and listen to your transmit frequency on the 
main receiver.  Dual receive - not split. 

If you are the DX, set your transmit frequency on VFO B, enable 
dual receive and split.  Tune the callers in the pile on VFO A. 

There is no reason to use the large knob to control the KRX3 
since the KRX3 and main receivers are identical.
