It's been a while since the APF has really pulled out a signal for me that was otherwise impossible to copy. As W4ZV has said, its effectiveness seems dependent on the band condx (QRN vs signal strengths, etc). This morning the APF allowed a weak V73QQ to pop out of the noise on 160M. Tuning with APF is very critical (width is only 30hz) and I use the K3's fine vfo tuning rather than shift. But yes, APF is still working just fine ;-)
