”......And when one QSO partner repeats either R-10 or RRR or RR73, it is his indication that he didn't copy the ack,....”
Surely that statement is wrong. You only send RRR or RR73 to CONFIRM receiving the other stations “R” ack, never to indicate no copy. Sending R -10 means you copied the other stations report, you keep sending it until you get RRR or RR73. Once you get it, that’s the end of the QSO. Nothing else required. If you don’t get it, it isn’t a QSO. I think the WSJT message exchange protocol is based on decades old moonbounce and MS procedures where 73 is simply a luxury that often isn’t affordable.

Wrong. The definition of a QSO is the exchange of callsign and one piece of info by each party, and the acknowledgement of receipt by by each. Each station must receive acknowledgement of the other's exchange. If that "information" is the signal report, The first ack is the R in R-10, the second, by the other station, is RRR or RR73. What is NOT required is 73. But it IS required for each station to have copied the other's ack. And when one QSO partner repeats either R-10 or RRR or RR73, it is his indication that he didn't copy the ack, and the other station should repeat the ack. 73, Jim K9YC _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
