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.
