But if you do this, will you be transmitting on the correct 
frequency with FL2-4 shifted as you describe? Or will the received
signal (using FL2-4) BFO shift -- to do "passband tuning" in 
effect -- cause you to tune in the received station at a 
frequency different from where your K2 will transmit, using FL1 
in the transmit path?

I hope you understand what I'm asking. I don't have a KSB2 (yet)
so I can't experiment.
