The APF will take signals in the noise and make them very readable.
Yes, it is very good once you get the hang of it. I move the peak just a tad off of the center of the passband. It really seems to make a difference ... might be a result of my very compromised hearing, don't know..
It
is not something you will need to use all the time.
There have been several posts over the time that APF appeared from people who use it essentially all the time. I use it a lot on weak signals at the noise, but not nearly "all the time." Any CW signal that's above my noise just stands out on the K3. APF also seems to help with multiple very weak signals in the passband. My guess is that when they're all at the noise, it's hard [at least for me] to actually associate a tone frequency to each, and they sort of just merge together. APF will usually yank the one I want out of the muddle.
