[RTTY] PSK31 is faster (Was FD RTTY Question)

[Tom Osborne]

Hi Chen

I had a model 28 here 'back when', but it was only a 60wpm machine (I 
think it was 45 baud).

Some of the 28's actually had a transmission that could shift from 60 to 
75 and some 100 wpm.  I can't remember what the baud rate was for each 
speed, though.  73
