For normal/mpx output, Is it possible to have that option?

Isn't that what "FM Calibration" does (for the MPX signal)? Or do you mean something else?

ohh yes... i totaly forgot that "phase difference calibration " can do that.

is it then possible for normal output ?

edit:
ok what is the way i calibrate this.

i put 40Hz square tone to ST and watching scope.
With 40Hz slider i can set tilt.
So i must do that with all tones .. or i can set all other sliders same as this one at 40Hz.

Ok, you have a scope...

Question, the way this "fm calibration" window is set up now means that it's very flexible, but also that it's difficult to setup. My own (15 euro battery powered...) transmitter needs this kind of flexibility, but I can imagine that for better quality equipment a single 'tilt' value might also suffice. Do you know anything about this?

i just tryed to see how 192kHz onboard soundcard can be "tilt" calibrated.
so, when i put 40Hz square tone thru ST.. i see that this soundcard have tilt.
with this slider i can fix it.

i ask this because currently my stream is on Realtek soundcard and i assume that this card have big "tilt"
So i am searching the way how to callibrate it.

I don't put it in transmitter because i just wont to calibrate soundcard output, mpx or normal output!

On breakaway there is option "tilt correction" and Tilt "Coeff" for mpx and for normal output.

I did't yet try how Juli@ show tilt but i read that someone measure very small tilt.
useffult prog is BreakawayRTA .. maybe enough to be used like scope.
Even there i can see how my onboard soundcard shows bad tilt.
