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.
