One way is to center the tuning of the desired signal in the center 
of the passband of the filter of choice by "S" meter, then use the 
BFO pitch control to tune to the correct voice sound.

Another way is to favor one side or the other in the filter passband, 
upper side of the filter for LSB and lower side for USB, and THEN 
use the BFO pitch control as above.

Your problem is ONE reason certain R-390s had a vernier control 
on the BFO pitch control.
