If I think of a reason Bill, I'll let you know.  I managed 625 Q's in a 
sort of sporadic effort in the CQ WW RTTY this last weekend with N1MM, 
MMTTY, my laptop w/sound card, and two Radio Shack audio cables between 
Line[s] In and Line[s] Out on the laptop and K3.  My AFSK A pitch is at 
915 [I can hear that, I can't hear much higher than that, YMMV] which is 
also what I set in MMTTY, and that was the end of the set-up other than 
the levels which weren't at all hard.  Be sure to turn off all the 
Windoze noises on your computer.

I haven't really mastered dual-PB yet, or maybe I have and it's not a 
lot different than non-dual-PB.  I do know that MMTTY was decoding 
stations [and I was working them] that I really couldn't hear, I could 
just see their faint trace on the WF.
