Julian,

Using FSK instead of AFSK means you can run a big amp Class-C and get more 
power output. Also, you do not have to worry about preserving linearity on a 
Class-AB or Class-B amplifier if running FSK,or figure out how to interface the 
computer to the rig for AFSK.


You do not seem to understand how the so called AFSK works for RTTY.  Using any 
clean transmitter  and pure sine wave tones the signal comming out of it will 
be the same if true FSK or AFSK is used.   The amp can be the same class in 
either case.
