Hello all, I recently replaced the 5-pole 2.7kHz roofing filter in my K3 with the 8-pole 2.8kHz hoping to get rid of the difference in tonality between USB and LSB. But the difference is still there. These two links show the noise spectrum of the receiver in USB and LSB.

Is this normal and is there anything I can do about it (other than asking Elecraft to add by mode equalizer)?
