On my MK V (also fairly recently aligned by Byron Campbell), I can distinguish a VERY subtle change in character when switching between USB & LSB. Make certain that both SHIFT and WIDTH controls are centered, and that there are no birdies in the bandpass. My MK V has a few rather faint birdies which, if within the bandpass, could result in a distinct pitch change from USB to LSB.

  Just checked my FT100MP and have the same thing between USB and LSB.
  My radio has just returned from being completely gone through by Byron Campbell
  so you KNOW it is correct. I heard the same before I sent it to him. There is a
  very definitive pitch change between the two.
