[Elecraft] K3 PSK no output

[K5HM]

Using Tigertronics sound card. Followed the set up instructions for PSK in
the Fred Cady, KE7X book. Installed the K3 jumper block from DX Engineering,
and the K3 interface cable. Using Digipan, I try to call CQ. Rig goes 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.
