This is clear enough that I can actually see something I can understand. The discriminator response is supposed to look like one cycle of a sine wave with 21.25mc exactly at the Y=0 origin. There's supposed to be 360 kc between the peak and trough of the wave or 180kc on either side of 21.25mc. Those marker points of 21.07mc and 21.43mc are exactly at the high and low peaks. The issue now is no matter what I do to T-113 to adjust, I can't get the curve to come back up to Y=0 after the 21.43mc marker to complete the wave symmetrically. It just sorta tails off.
