Is this true? That would be splendid. I'm using LP-Pan, but I have a P3 that
I might resuscitate if it exported I-Q.

I checked with WSJT9/JT-65B running the spectraJT waterfall:
I have no Rx EQ set up.
TX EQ for SSB is -16, -16, -9, 0, 0,+3,+6,+6
With USB I have display 500-Hz to 2800-Hz
With DATA I have display for 900-Hz to 3400-Hz

Ed, what is your firmware version? One of the reasons for DATA A was
to remove SSB features that were inappropriate for data modes.

Ed,
If I remember correctly, when a DATA mode frequency memory is stored in
the K3 the data sub-mode is remembered as part of the information stored
at the time the memory is created. For example, if your K3 data sub-mode
happened to be AFSK-A at the time the memory was stored, I believe the
I don't understand why you want 13 kHz for JT65.

From this it appears TX EQ affects the audio passband in DATA., as
well as, SSB.
No, from that it appears that you have DATA configured for AFSK A and
not DATA A. AFSK A shifts the passband to center on the MARK/SPACE
tones as defined by the MARK frequency - i.e., FC = (MARK+SPACE)/2

OK, thanks. I had not altered DATA-MD since the radio arrived from
Elecraft. I guess that was set-up default for AFSK A.
I also note that I found the WIDTH control was narrowed to 45bps in
LSB, so I opened it up as high as 4-KHz. There is still roll off
below 200-Hz. That is fine for me as
I continue to be puzzled by this thread. Given that WSJT (all modes) is
WRITTEN for use on USB by Joe Taylor, WHY would we be interested in utilizing
any K3 mode but USB?
I have operated 441 and JT65 utilizing my K3 off the Moon, tropo and MS with
no desire to fuss with any other K3 mode.
DATA A *is* USB with no equalisation, etc - that's the point. It
allows you to easily switch between SSB and data modes without having
to adjust audio processing for each.
I just looked at my passband, with spectran, in DATA A and USB modes
with the bandwidth cranked up to 4.0kHz (in both cases)
Bill,
What you are missing is that many operators *do* use compression and
TX EQ for SSB work.
DATA A is the same as SSB, but TX EQ is automatically turned off and the
compression setting is set to zero.
Other than those two items, DATA A is just like SSB - Oh, it will also
remember that the

Probably, but even if I shift downwards in DATA A mode, there's still
a cut-off at 200Hz.
