Hi Frank,
I would not expect the waterfalls for the JT modes to change because the JT
modes transmit only one tone at a time. Apart from turning the tx on and off,
the amplitude of the signal does not change. Therfore there is no source for
IMD that could result in a broader signal or splatter.
I played with the ALC to just get the onset of ALC but no luck

If you want to see your transmitted signal on the waterfall, go into FLdigi
config settings Waterfall->Display->Transmit signal and check the "Monitor
transmitted signal" box.
The level settings you have are similar to what I use, but check the TX level
as Don describes in another response to y
Dave,
Do you have the transmit audio levels set correctly? The ALC meter
should illuminate 4 bars during transmission with the 5th bar
flickering. If that is not the case, increase the audio drive level
(either soundcard settings or KX3 mic gain or both) until that condition
is met.

The waterfall display normally stops during transmission. That is not a
problem.

The Fldigi waterfall display and the rig control/frequency display are

the rig control/frequency display comes from the computer to KX3

I think the best solution would be to try it both ways and see what kind of
signal report you get. I'd be interested to see the two JT waterfalls
compared side by side.

I think it's a good question, but I cannot answer it.
Most amps produce more distortion the more power they run.
The question is whether the sum of distortion from both amps at lower power
is less than one amp running at higher power.

Basically, there is nothing wrong with your plan. As long as get

your approach is $100 cheaper, but if it doesn't work without you

As Don has pointed out
"Note carefully -- for the KX3 (and K3) in data modes, the "ALC" meter is also
used as a level indication. Adjust the mic gain to produce 4 bars on the meter

the onset of ALC."
>From Fred Cady's
you dont need a signal link with the kx3. the all you need is the cables
from elecraft and the usb control cable. and a app like fldigi.
the usb cable does all the ptt and freq control via hamlib. the signal
like is just a middle man that is not needed.

Please read the data operation section of the KX3 manual. You need to
set the Tx audio level so you have 4 bars of ALC, and preferably
flickering the 5th bar.
This is not a misprint.

Good points Barry, especially about ALC - in data mode, the KX3 will
disable compression and equalization. Use DATA A Mode (or AFSK for
RTTY) with soundcard data. Trying to use SSB mode on the KX3 requires
more attention to compression and equalization.
