I'm generally not a fan of using audio peaking filters (in my early years of hamming, I spent too much time listening on receivers that had audio filters instead of adequate IF filtering), but I grudgingly thought the APF on my TS-940 made the difference between readability or not in certain weak signal situations on 160 and 80.

Despite its DSP-based audio contouring, I've missed having an APF on my TS-950SDX (over a many-year period) and I'm thinking I wouldn't mind having a tunable APF on my K3 (which I've had for only a few weeks) as well.
