  Robert,

Do you have the sideband set correctly? - both MMTTY and the K3?  How 
about the mark frequency? - they must match.

Instead of two-ring figure for the MMTTY XY plot, I only get a blob and jibberish printing out.  When running WriteLog, the sound card is able to take WAV files and input them to my K3 transceiver.  So the sound card is not totally dead.  I have been over and over the MTTY setup and am confident that the setup is OK.  Of course I could be missing something.  I am beginning to suspect the motherboard mounted sound card is messed up.  Any tips/tests will be greatly appreciated.  My next step is desperation and to try an outbouard USB sound card.  I read some reports that this might be better anyway.
