Audio artifacts in DATA A mode with KX3

I'm seeing some unexpected audio artifacts when using DATA A mode with the
latest production firmware on my KX3, on all bands. This is something I
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.

Pictures of the waterfalls for comparison here: http://imgur.com/a/AjHu4

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.

worth supporting.

Re: Audio artifacts in DATA A mode with KX3

Jörg 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:

Re: Audio artifacts in DATA A mode with KX3

Back when I was playing with SDR's I would notice the same thing (Deep nulls)
Sometimes resetting the software (or turning the rig on and off again) would cure it.

Something to try

Re: Audio artifacts in DATA A mode with KX3

In reply to this post by Nicklas Johnson

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.

Re: Audio artifacts in DATA A mode with KX3

In reply to this post by Elecraft mailing list

Harry,

This isn't a switch it on and off again problem I am afraid. It is simply that the KX3 Data Mode is restricted in bandwidth at the low end, unlike the SSB mode on the same radio. Bizarre but true.

It was worth a shot, l permanently loaned my kx3 to my son , else I'd test it here.

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

Re: Audio artifacts in DATA A mode with KX3

I've noticed the same kind of issue at times, also. I've never known to what to attribute it to. To be far, it's not just Elecraft rigs. I think it may be software glitches rather than transceiver problems.

Nick,

Help me here.... I don't see any connection. You could still be crazy and
experiencing the Audio Artifacts as well. :)
