Hi.

I just joined this list.  I'm enjoying using FT8 on HF bands.  Many thanks to 
Joe Taylor and Steve Franke.  I'd like to report what I think is buggy behavior 
in the FT8 auto-sequencing state machine.  In future I hope to contribute to 
development of this very cool software.

Environment

My radio is a Flex 6300.  My computer is a MacBook Pro running macOS 10.12.6.  
I'm using VMware Fusion Pro 8.5.10 to run a Windows 8.1 VM, which is up-to-date 
with "important" patches.  I'm using SmartSDR 1.11.12 and WSJT-X 1.9.0-rc3.

Example 1

In the following QSO, I responded to his CQ but didn't hear back right away and 
disabled transmission.  A minute later I received a -19 signal report from him 
(A) and double-clicked on it.  The software sent a -20 signal report to him 
(B).  I think it should have sent R-20, with an R.  (Nonetheless, the QSO 
proceeded to a successful conclusion.)

015730 -20 -0.2 1378 ~  CQ N0GOS DN70
015747  Tx      2258 ~  N0GOS W6SDD DN70
015815  Tx      2258 ~  N0GOS W6SDD DN70
...
015930 -20 -0.2 1377 ~  W6SDD N0GOS -19  <<-- (A)
015946  Tx      2258 ~  N0GOS W6SDD -20  <<-- (B)
020015  Tx      2258 ~  N0GOS W6SDD -20
020030 -22 -0.3 1377 ~  W6SDD N0GOS R-22
020046  Tx      2258 ~  N0GOS W6SDD RRR
020100 -20 -0.3 1377 ~  W6SDD N0GOS 73
020115  Tx      2258 ~  N0GOS W6SDD 73

Example 2

This next QSO proceeded normally up to the point where he sent RRR and I sent 
73.  I have the software configured to disable transmission once I have sent 
73.  A minute later he sent RRR again (C).  I double-clicked on it.  The 
software sent him an R-18 signal report (D).  I think it should have sent 73.  
I selected 73 from the list of messages and the software sent 73 on my next 
turn.

041145 -17  0.4 1433 ~  CQ KK4EUN EM60
041201  Tx      2228 ~  KK4EUN W6SDD DN70
041215 -15  0.4 1433 ~  W6SDD KK4EUN -23
041230  Tx      2228 ~  KK4EUN W6SDD R-15
041245 -20  0.4 1433 ~  W6SDD KK4EUN RRR
041300  Tx      2228 ~  KK4EUN W6SDD 73
041315 -10  0.4 1423 ~  F8NHF KE8EF R-04
041415  -7  0.4 1423 ~  F8NHF KE8EF 73
041415 -18  0.3 1433 ~  W6SDD KK4EUN RRR   <<-- (C)
041432  Tx      2228 ~  KK4EUN W6SDD R-18  <<-- (D)
041500  Tx      2228 ~  KK4EUN W6SDD 73

I hope this is helpful.

Best regards,

Scott Davis
