Stereo Tool :: Reincorporate VU of MPX and L and R Demodulated

That should be the darker blue color in the "O" meters. (Aside from that, how are you using this meter to calibrate anything?)

Perhaps, as a suggestion, it would be good to re-implement that meter in the MPX area.

But it's there. That's the Output peak meter bar, labeled "O", found on most pages. Is it not tall enough to show overshoots or something?

(I will explain it from our experience, so maybe it is wrong, but it has worked for us without problems): 1.- We calibrate the level from the mixer to the StereoTool input with 400 Hz and 1 kHz tones so that it is around -6 db. 2.- The AGC, Multiband, NG, Etc. settings are applied. 3.- Finally, the StereoTool output is adjusted to the MPX input of the Transmitter. At this point we use the Instant MPX Meter, because if we let the white video and capture meter continually touch the maximum, we know that that is the maximum level of StereoTool with MPX, but we must adjust the output of the soundcard to match those 100% of the StereoTool with the 100% of the input to the Transmitter. In summary, in our case, with an old computer, the coincidence between 100% of StereoTool with 100% (75 kHz) of the input to the Transmitter, was leaving the volume of the soundcard around 60%. Perhaps, as a suggestion, it would be good to re-implement that meter in the MPX area.

Is it not tall enough to show overshoots or something? So, the "O" meter that has 2 shades of blue, which also indicate L and R, marks the level of the MPX signal? When the MPX signal remains below 100% it remains blue and when it exceeds 100% it marks red? Best regards.-
