Hi Bill,
    I don't have an NC-303 but I'd be 99% sure that it should be at half 
capacity when the control knob is at the center of it's movement.  Thus you 
can move the BFO freq. a bit plus or minus from the IF center freq. 
(assuming that it had been set at the proper freq. & not drifted off).
