[Elecraft] Help with K3 and Signalink USB

[Doug Shields]

Hello everyone,

     I am sure there is a simple and thoroughly obvious answer to this but I
haven't found it.  I have a K3 connected to a Signalink USB interface.  I am
using the specific K3 cable that plugs in to the speaker and mic jacks on
the K3.  I believe I have the internal jumpers on the Signalink set
properly.  I have adjusted the sound card levels as recommended.  

   I can receive everything and decode signals just fine using Ham Radio
Deluxe.  I just can't transmit any digital modes.  I have tried many
combinations of settings with no luck.  The K3 goes into transmit but I get
no indication of RF output.  It works fine on CW and SSB.

    What am I missing?  Thanks in advance.
