A  back-to-basics question for once...
 
Is there any modern RTTY datacomms software that gives a single wire digital 
output for driving an FSK transmitter?   Looked in the MultiPSK and MMTTY setup 
menus and nothing.   
 
While I realise there may be little call for such a one-wire  drive now 
(although my not-too-old IC746 will take a RTTY input signal) it does lend 
itself to simple QRP designs for the less experienced constructor.
