That was what I used to think, too.

See archives of the RTTY Reflector here:

By the way, it should have been "Keyed-AFSK," (i.e., the FSK keying  
signal is used to shift the AFSK signal), not "Keyed-FSK,: which does  
not make much sense.

I'm still using the same FT-1000MP -- approaching 10 years now and no  
blown finals or cold VCO solder joints yet :-).
