It's not Trace Aplpha inperfect but your MPX input at transmitter. It happens all time.
Measuring only TILT in Trace Alpha gives perfect Tilt, but when i wanted to attach it to transmitter Tilt moved, just a bit.
Same with rds and pilot.
- Also, Pira shows "diff", and i always wandered should Pilot or RDS need to be adjusted. Or both.

Activating LSB or USB does only bring silence to the right speaker!?
It's not LSB and/or USB..
It's just used to activate and listen silented channel while adjusting pilot phase to get as minimum sound as possible on silented channel.
