Not every mode has a place on every band.

ESSB has no place on any band where wideband FM is not permitted due
to the bandwidth.  Amateur radio is a communications service, not a
broadcast service and 2.7 KHz is all that is necessary for clean SSB
with reasonable fidelity ... audio that does no sound tinny, muddy or
hollow.  The only thing necessary is some appropriate audio shaping,
equalization and processing.

The ESSB boys that insist on ruler flat audio response from 25 Hz
to 5 KHz (or more) with both bass and treble boost to accomplish
that flat RF mask are often more difficult to tune and listen to
than a well equalized and properly processed standard 2.6 to 2.8 KHz
SSB signal due to the non-flat characteristics of the ionosphere.

The ESSB on the K3 would be better called “better sounding SSB”, compared to what the hard core ESSB groups like to run.  It’s more akin to the sound of vintage phasing rigs (which sound very good generally).  And it IS better sounding SSB — provided the guy on the other end isn’t stuck with a 2.1 KHz mech filter or some other restrictive bandwidth.  Certainly it’s less effective in working stations close to the noise level, but that isn’t what ESSB is about anyway.
