I am seeing that option and have it adjusted for 150% positive peaks. Support for AM stereo was discussed in the past and from what I read about the asymetrical peak limiter it only works on the positive peaks and leaves the negative peaks at 100%. Might need to go over the thread again just to be sure I got everything correct. I also tried the suggestion from a past thread for sounding like an Optimod 8100 with the XT2 chassis and say it killed two birds with one stone. The audio sounds like an Orban Optimod 9100B if the matrix processing modes are selected and the audio passband is set to 12 or 10 KHz. I used to have an aircheck of KYCW 1090 out of Seattle Washington, a radio station that used said processor and those settings are about a dead ringer to what I remember. Its actually driving a part 15 legal Motorola C-QUAM AM stereo transmitter which seems to have a range of about 2,000 feet.
