Mike and Jim
I am having the same problem on 40 M only with one of two K3s. Both have
new synth boards and antenna tuners bypassed.

This is on the KX3 firmware list. I'll move it up a notch.

Nick,
Thank you for bringing this up.
I never did get a satisfactory explanation, I contacted support too but that
didn't get me anywhere either, I don't think they understood my question, which
is quite simple really, why can't we get the same bandwidth in Data mode as in
SSB mode? I think it's a simple oversight, but nobody seemed interested in
acknowledging it or fixing it.

J?rg in the Elecraft KX3 group on Facebook had an interesting observation:
with WJST's waterfall, if the "flatten" mode is on, it produces some
unusual artifacts in the presence of sharp spectrum drop-offs, and indeed
if I turn off the "flatten" feature and manually set the zero point for the
waterfall, the artifacts go away.
It's still an open question as to why the data-a mode has a steep drop-off
at 400Hz when the PBT settings on the rig would seem to indicate otherwise,
and the same drop-off isn't there in USB mode.
I see searching on "400 Hz" that GM4JJJ had the same question here on the
last back in July 2015, but never really got an answer. I basically have
the same question as this one:

I'm seeing some unexpected audio artifacts when using DATA A mode with the

observe when the PBT BW is set all the way wide (4KHz) and FC is centered.
In DATA mode, there's an audio drop-off between 200 and 325 Hz, with an
almost completely dead audio "hole" between 250 and 300 Hz. Then there's
some additional noise between 350 and 500 Hz.
If I switch to USB mode (with no EQ or audio effects applied, naturally),
all of these artifacts go away, and it's perfectly smooth across the
spectrum. No drop-off, no noise.

Am I doing something wrong, or is there something I should check? I've
taken the usual steps, but it's plausible I've missed something.

Saying something doesn't make it true. Belief in something doesn't make
it real. And if you have to lie to support a position, that position is not
worth supporting.

Thank you, Wayne! At least we know we're not crazy :-)
