+Contest QSOs are generally treated as invalid when they appear in one

+guidelines for contest logging with FT4, FT8, and MSK144:
+
+ - Activate and learn to use the alternate F1-F6 bindings selectable

+ 
+ - Always log a QSO when you have received RRR, RR73, or 73 from a
+   station you are working.
+
+ - Log a QSO when you send RR73 or 73 if you are reasonably confident
+  it will be copied. But be sure to watch for any indication that it
+  was not copied, and then take appropriate action. For example, if
+  you receive the Tx3 message (R plus contest exchange) again, hit F4

 In many ways JT65 operation on VHF and higher bands is similar to HF
