Keith - I agree and I think that this is more of an issue with newcomers to weak signal VHF not knowing the protocol for what is a complete QSO and what is not. I would find it hard to believe that anyone familiar with waiting for the last rogers and 73s in a SSB/CW QSO would have trouble waiting for them in an FT8 QSO.

I suspect that over the years that you and I have been working contests we have spent a couple of hours waiting for those last rogers and 73s.

A hard lesson to learn for newcomers is that if you have heard a person once on troposcatter, you are likely to hear them again if you wait long enough.

Don’t forget to unshift on FIGs. - Duffey

"Reasonably confident" are the watchwords here.

Many FT* NILs are, I'm certain, caused by guys simply sending their RR73 once and moving on, no matter HOW LONG it's taken to get to that point.  If the QSO has taken a while, the chances of the other station receiving that RR73 on the FIRST OVER are slim.  The answering station never logs the Q and, bingo, a NIL !   If you're going to act like you're all big and loud, you might as well be on SSB where you can run a decent rate, instead of on a 40/hour (if that) mode.

On the other hand, when using FT* it's IMPORTANT to ACKNOWLEDGE those RR's or RR73's, at least until you copy the guy you (think) just worked you sending 73, CQ or immediately working someone else.  If a guy who's CQing is at all interested in his bust rate, he very well might not log you without SOME indication that you actually received his RRR or RR73.  I don't...

BTW, the same goes for meteor scatter modes like MSK144.  Be REASONABLY CONFIDENT and/or ACKNOWLEDGE !  Just say no to NIL !

This is good reading and useful information.

The first point, learning to use the alternate F1-F6 bindings, is also good for QSYing stations to other bands. - Duffey

This is worth a read.
Especially as more and more users are discovering that they can take part in VHF contests by using the digital modes.
Here is what I think is the most important part of the PDF.

As a general set of guidelines for logging in FT4/FT8 contests we recommend the following:
  • In WSJT-X, activate and learn to use the Alternate F1-F6 bindings selectable on the Settings | General tab.

  • 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 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 to re-send your RR73.

Log checking for several recent contests that used the FT4 and FT8 modes
has shown undesirably large numbers of claimed QSOs that receive
not-in-log ("NIL") status from the other station.  The WSJT development
team has worked together with contest sponsors and log checkers to
analyze the probable causes of these NILs.  Our findings and some
operating advice for future contests are posted here:
and will also appear in the May-June 2020 issue of NCJ, the National
Contest Journal.
