I FOUND A SOLUTION TO MY PROBLEM!!
YESTERDAY NIGHT I MADE THE BIG TRICK !
How CAN you be MAX possible BASS, and MAX possible TREBLE without affecting your FM EXCITER performance ?
CUT OFF on the final stage everything under 20 hz low bass ON THE FINAL STAGES !!
------------
how did i solve it ?! after 2 years of FM exciter modulation power overload
strict bass clipping and very strict selected also !
CLIP STRICT FROM 0 up to 20 hz !!! ( no more than 20 becuse u will lose loudness)
AFTER PUNCH CLIP IT BELOW 0 %
BOTH DDS EXCITER and analogue exciter AFTER 2 YEARS FINNALY
PERFORM LOUD AND CLEAN !
so, if you ve made a loud preset for your FM station , DO THIS TRICK but ONLY WITH STEREOTOOL. DONT try to do this trick ( cut everything under 20 hz on the final stages ) with any other clipper ( hardware clippers, hardware dc protectors ) becuse YOU WILL CREATE OVERSHOOTS on the mpx signal.
SO , i can ...go to sleep now
( BEFORE this trick , my second IF frequency was going from 324,1 to 325.2 ..with max 75 khz of modulation
AFTER this trick , my second IF frequency is stuck and stable at 325 khz which is the correct for precise fm frequency !!!!!!!! with 75 khz of modulation.
IT WORKS !!!!!!!!!!!!!!!!! and my FM modulation power increased! ( 8 dbr now! more loud!!)
