You are far better served to use DATA A with the Signalink (or
any other interface).
DATA A has several beneficial features:
1) it (typically) selects audio from the line in jack and mutes
the microphone - meaning that one does not have background
noise and hum from the mic interfering with the modulation or
causing broadband interference to others
2) it disables TX Equalization so audio levels are not up/down
depending on where in the transmit passband one is operating
3) it disables the compressor so one does not get distortion or
generate IMD to others operating nearby
4) it changes the "scale" of the ALC meter (expanding the range
around the "4 bar" position) so it s much easier to set the
correct modulation level for optimum audio input level.
In short, connecting any audio interface to "Line In", using DATA A,
and setting Mic+Line = off is the proper way to use the K3 for data
modes - for both the best performance and as a "good neighbor" on
the air.

K3 does not have to be in Data mode to work with the Signalink.
I use it all the time in SSB (USB) for data modes, especially for PSK31.
Most data mode software has built in filtering/DSP so the wider
bandwidth on receive works very well, for PSK31, and other data modes.

Be sure you are in DATA mode, not SSB mode. You will get no output in SSB
mode.

As a K3 newbie here, would the mic impedance (H or L) be a possible
issue? I
could not get any ALC movement until I went to H impedance for the Heil
headset I have. I was then able to get all the ALC needed with the mic
gain.

Ron,
Try in TX TEST mode - everything goes into transmit except there is no
RF output.
Adjust the audio level (both SignaLink and the "mic' gain on the K3)
to obtain 4 bars solid on the ALC meter with the 5th bar flickering.
If you are not able to obtain that level, check the SignaLink
documentation to determine how to plug it for Line level audio output
- I believe it is a jumper, but the default position is for low level
output (mic level).
Once you are able to obtain the proper deflection on the ALC meter,
get out of TX Test and try it. You should have RF output.

into
transmit mode, the macro runs but no power out. Adjusting the TX pot
on the
Signalink does not make a difference. I can receive Ok. But either the
soundcard is not outputting anything or I missed a step in the setup.
Config.Lineout is 10 as recommended VOX/No VOX does not seem to
matter. Rig
is in Data A mode. I must be missing a step in set up.
Suggestions welcome.
