===========
Terry, try it without the Signalink. Just plug the audio cables directly
from the Line In/Out jacks on the K3 to your computer. Adjust the K3's ALC
bars and power output as described in the K3 manual, not the way that the
Signalink instructions say. The K3 is different from other transceivers in
that the output power should not be governed by drive, but rather by its
internal power-management scheme.

The K3 does not require an interface to do AFSK, PSK, WSPR, JT-65 or any
other digital mode. You can get good results just with two cables,
because the K3 has isolation transformers built in.

After you get everything going, you can then insert the Signalink into the
loop. It has its own sound card, which will probably do a better job than
the one in your PC in terms of S/N ratio on weak signals. The process will
be easier after you've shaken things down without the additional complexity
of the external interface. When the Signalink is in the loop, you still
want to adjust the ALC and power as explained by the K3 manual.
