[Elecraft] K3 Sound card hookup HELP!!!

[n5ge at n5ge.com]

I'm setting a SignaLink USB up on my K3 and am having trouble getting it to
transmit.

The rig is keying and the TX LED is lighting but I'm getting no power out.

I'm connected to the LI/LO and PTT on the rear of the rig.

I'm receiving well in DATA A mode On Main Menu MIC SEL is set to Line In.

Any one have a check list I can follow?
