[Elecraft] K3 a few new user questions

[Bill]

Let me get this straight:  a SignaLink USB box plugged into the K3, 
software is DigiPan, mode is USB, and power reduced to 25 Watts.  
Acceptable?

This is what I have used on other rigs for several years with fine 
success. What I see here regarding PSK and the K3 seems to go over my 
head. What am I missing?
