Stereo Tool

Just a minor thing, but I cannot find anything in ST with what I can shift the pilot-phase to compensate phase-imperfections within the RDS-carrier. In Airomate, this is possible:

Airomate-RDS with phase-shift:


StereoTool build-in RDS:

There is: Go to FM sound card -> Calibration. There you can calibrate each frequency - please note that an offset at 57 kHz (RDS) means that there are (probably smaller) offsets at other frequencies as well.

I want to make something better than this in the future - it causes extra latency.

Aah, yes - my bad!

Moving the 19 kHz-phase a notch fixed it. Seems that the Trace Alpha I'm using is not as perfect as everybody claims Or it's the exciter that scrambles the phase a bit...

57 kHz and some other frequencies are greyed-out - is that on purpose?
And activating LSB or USB does only bring silence to the right speaker!?

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.
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.
