Having enabled 13kHz roofing filter for digital modes, i enlarge K3 DSP filter width to 4kHz for watching FT8/JT65 and PSKs.

You sometimes find interesting stations to work well above 2.7 kHz.    Working out to 5 kHz is no issue with a TS-590 as long as WSJT-X and the rig are configured for split.
