During the CQ 160 contest, I found myself leaving the APF on and using that on top of a .4 KHz DSP bandwidth. Signals just jump up as you tune across, making zeroing easy even for someone like me that has very little tone discrimination ability. Of course, I got used to doing this with a TS-930, and have relatively high tolerance for ringing and distortion.
