K3 #202, MCU 4.18, et al. Similar experience here. Everything normal until I rotate the APF Shift CW and it reaches 1.00 the loud pops/cracks begin when rotating both the "Shift" and "Width" knobs. Rotation of the APF Shift knob now changes the display numbers (APF 0.xx), but the Rx is very quiet... both speakers and earphones. Powering K3 OFF/ON returns the K3 to normal operations. When I cycle back to APF Off (Preset II on my K3), Rx works normally with sound in both speakers and earphones. The first time I switched back to Preset I (APF On) the Rx worked as it should. Subsequently, switching back to Preset I produces a quiet Rx with only the popping when the APF Shift or Width being rotated.
