The only radio I found APF extremely useful was my FT1000D. It could pull essentially inaudible signals out of the noise on 80 and 160. I believe Yaesu modified and broke the APF in later 1000D's, and there was a mod to resurrect it. I found the APF in my Icom 7800 worthless.
IMO, implemented the right way, as in the early 1000D's, it would be a useful feature.
