Wayne,

Understood, but why would anyone want to have a filter peaked at other than the nominal sidetone pitch?  I realize people are asking for it, but it makes zero sense to me.

Wes,
When I used the FT1000D APF on extremely weak lowband signals, I didn't want to touch the tuning knob, for fear of losing the station.  Once I heard a trace of a signal, I'd engage the APF and vary to pitch to bring the signal out of the noise as best I could.
