Ah - you are right, Reino.
I did not consider that the Run station will repeat the report only if
my RR73 is not received. If I, as the S+P station, do not receive a
repeated report, the Run station did receive my RR73 or QRM/QSB trashed
his transmission. I was primarily seeking some positive indication that
the Run station received my RR73 - much like the final TU in RTTY
contesting. However, as you correctly point out, a final 73 from the
Run station is unnecessary.

Hi All,
I think it would be helpful for the called station to return a 73 message in
response my RR73. As things are now, if I received nothing after sending RR73,
I do not know if the other station received my RR73 or if I could no longer
copy the other station due to band conditions or QRM. If the other station
started a new CQ, I took that as confirmation.
Let's assume that all stations follow principle stated in 'The FT4 Protocol for
Digital Contesting':
'FT4 is presently configured so that a station operating in Search-and-Pounce
(“S+P”)
mode logs a QSO when RR73 is transmitted, and the CQing (“Run”) station logs a
QSO
when RR73 is received.'
So after sending RR73 you may receive:
- 'R-nn', if the other end missed your 'RR73'. It is his interest to complete
QSO as you are already 'happy'.
- CQ by the other end. He has received your 'RR73' and logged the QSO or is no
more interested in to complete this QSO with you.
- The other end is calling somebody else. As previous case.
- No signal on the other end frequency. As previous two cases or a deep QSB
(see no decode).
- A signal on the other end frequency, but no decode. This is an interesting
case as the missed message may be any of the three first cases or a third party
is now on that frequency (QRM). Only 'R-nn' is relevant to you as you may miss
a multiplier (or a new head). You may resend 'RR73' or perhaps '73'. For that
you may already during reception cycle restart TX and select M4 or M5 as Next
and place your pointer to M6 or Halt Tx ready to click on the missed decode.
Well, this issue is not fully black and white; it is a matter of taste how to
behave in a contest in order to get best total result, hi!
Actually message with '73' is not really a part of minimum contest QSO and a
sending of it should not be forced in automatic steps or by users. It's polite,
not a part of a minimum QSO.
How much of the above should be a part of automatic program steps is another
issue.
