The noise you see on the waterfall should correspond with the DSP BW
you have set using the WIDTH knob. The TX filter must be either the
2.8 or 2.7, which ever you have installed.
Indeed, I can increase the width by adjusting the DSP BW width, but
only to a small degree.
As for the filters, I installed the 2.8 kHz and 400 Hz filters, and
apparently assigned the 400 Hz to data modes. But as I indicated in my
other message, I'm having trouble switching the data mode to use the
narrower filter to see if that makes the waterfall the right width.
Put the radio in TX TEST mode and hit the software TX button to send
audio to the K3. Now adjust using the MIC gain control (sets the
line in level) for 3-4 bars ALC. If you are not getting any ALC
reading your soundcard output may be set too low. Try increasing
that and try again. I have good success with the soundcard output
set to about 20%.
Here I'm stumped. My directions for setting ALC in general are
different than setting it for DATA and nothing for DATA speaks of
putting the K3 in to TUNE mode.
When I do hold the TUNE button to enter TX TEST mode,
Holding the TUNE button does not enter TX TEST mode. Holding the
MODE "UP" (^) button enters TX TEST mode, which allows you to
adjust your TX settings without putting a signal on the air. TUNE
produces a carrier on the air to allow you to tune your amp / antenna
system.
BTW, at least here, the meters always change to SWR / PWR when TUNE
is active, so there is no ALC reading then.

my display shows
that I'm set for about 20 Watts and that I'm using FL2 (the 400 Hz)
filter, but now the mode on the display has changed to CW. If I exit
TUNE, I'm jumped back to DATA mode. While in CW, the ALC reads 7 bars,
which is too much for DATA.
When I do software TUNE in my fldigi, while in the K3 DATA mode,
there's nothing registered on the ALC scale.
