One other question.  From what I understand, MSK144 takes the full 300 
HZ to 2700 Hz bandwidth. How far apart should the "slots" be? 3, 4 5 
kHz? The reason is, if I have to listen to two station via the rocks, I 
can handle 3 kHz spacing. But as this mode catches on, and it going to 
go the the general population real soon noww, how do I handle a ham 
neighbor 20 miles away running MSK144 at the same time? The 3 kHz 
spacing will be a problem for most rigs. 4 or 5 Khz would be doable on 
most.
