Hello David
The "why" behind full-duplex operation is an often asked question, also from our short wave friends QRV now on QO-100 (I'm more than 30 years QRV on OSCAR's). I found a good article about this theme:

I wish you success and 73

Did you read the WIKI ?

Once again George, what you mean is real full duplex operation. With a noise cancelling microphone or DSP programmed you can push the PTT all the time down in SSB (!) and "telephone" during the QSO. I hope I've understood you correct now. It is a good idea to bring "satellite full duplex operation" near to our shortwave friends.
-
What Martin described is real full duplex ! Our normal operating is to speak ... wait ... speak ... a.s.o. In full duplex you can interrupt your partner like at the telephone. Its not a question of mode but of operating.
-
What section you need to clarify?
If I understand you correct, you want to make more than 1 QSO (eg 2x2 operators = 2 QSO's) on the same frequency and at the same time in SSB (USB). My meaning is, this is not possible.
-
Can you explain better or are there more details somewhere ?

Hi,
I have a proposal for a "new" operational mode for NB.
The traditional QSO using USB in all frequencies is half duplex. This is due to the fact that is impossible to Rx during Tx. Using USB is possible two stations or more to talk at the same time without interfering each other.
The proposal is that two or more stations talk together like a telephone conversation. Of course callsigns must told every few minutes according to ham radio laws.
This will provide a more "natural" mode of communication that is impossible to implement with out QO100.
Hello George
I understand your "new" mode as Fullduplex. It's possible that both operators can talk at the same time, but if they are understanding each other is another question. As you know, a good operating practice and discipline is important in a roundtable.
Well George, I think this is an old hat for you and it is possible, I understand you wrong ?
