FSK requires only the TXD from a comport. In MTTY setup, under 
afc/atc/pll choose FSK, under the tx tab choose the comport used, and 
under the misc tab choose com-txd (fsk). A ptt connection is only needed 
for afsk, psk31, sstv and other soundcard programs. Select "fsk" from 
the mode selection on the Omni and that is about all you need to do, 
other than setting the pbt to 3 o'clock as per the manual.

PS No transitor type switching is needed, it is all done in the omni's 
fsk generator, again as per the manual and schematic.
