ever used "FSK"........

The FT100MP MkV Technical Overview says:
  "Thanks to very fast acting DDS circuits, a true frequency shifted keying 
carrier generator is provided for the MARK_V for RTTY use"   But then it 
goes on to muddy the water with some additional sentences that could be 
construed to contradict this.
Since I have already found the Technical overview to not be entirely 
correct/accurate - it is outright wrong in regard to add-in filters - we 
may never now ;<)
