200 Hz, provided by a passive, LC audio BPF. The final BW was set by the
tracking filter between the ears.

No comparison. IMHO, wasted effort by Elecraft Engineering.

Why? Because it's simple, works fine and is inexpensive.

use that for PSK-31 and like to
start in a wider BW. So, M3 and M4 have 400 Hz "saved." If I recall M3 to work
some PSK and I widen the BW to 2 KHz but then decide to work some RTTY instead,
when I recall M4 I discover that the previously stored (default) 400 Hz has been
ignored.
Works flawlessly using LP-Bridge here to "connect" the K3, SDR-IQ, N1MM and
DXBase.
