[Elecraft] Tuning VFO control

[Dave]

Hi-
 Tuning VFO-A also tunes VFO-B. I want to change that. I want VFO-A to just control VFO-A, and VFO-B just to control VFO-B.
 Now, if VFO-B is set to a different frequency than VFO-A, the two will retain their different frequencies and will track continuing that separation by turning VFO-A.
 VFO-B only tunes VFO-B. 
 I can tune VFO-B to a different frequency and then shift it into VFO-A position as I should. Then VFO-A continues to tune both and retain that new separation in frequency. 
 I don't have the sub receiver and no transverters.

I'm sure their is a simple solution, I just keep missing it.
