Yes and not. I mean, the IF Shift control still works and I can correct the 
IF frequency for better sound, but the resulst is not 100% the same as on 
it's standard setting. By the way - when the IF begin to wander, it always 
goes down, to the lower frequency. That's on CW or LSB, unfortunately I 
didn't check it on USB...
