Please give me a hint, if I think the right way:
IC 720A has a classic PTT-input (a switch at the mike) and a morse key input. It supports VOX.
Here are my thoughts, how to connect them:
For RTTY:
- using the soundcard is simple and already working.
- how do I manage the PTT?
?
Why not use the ?VOX“-function, that switch the tx on, when there is a signal from the?soundcard??
Will that be working?
But for CW:
- sound RX already working fine.
- how is the keying done? Does fldigi use? "1000 Hz on right soundcard output“ ?for CW-Keying?
? ?Is the 1000Hz-signal the signal for morse output?
? ?
PTT looks quite similar to my morse key interface. When I use ?VOX“ in CW-MODE the IC720 switches?
to ?send“. I just hit the key and transmittion starts.
?
WrapUP:
Can I manage it like this:
For RTTY: Use solely the VOX-function. Nothing else.
For CW: Build a 1000Hz-interface and connect it to the morse key input??

?I did not find an info (that I understood :-)) in 500 pages of docu.
