[Elecraft] K3 - FSK question

[JAMES ROGERS]

What software were you planning to use, MMTTY or maybe DM780. I know  
MMTTY supports "true FSK" as does the K3. Not sure about DM780. And  
yes, both of the above use the sound card for receive. The K3 will  
decode RTTY but the display is limited and as far as I know there is  
no provision for a remote terminal, so I would go the sound card route.

On your third question, I am curious about that myself and awaiting an  
answer from one of the gurus.
