I had a 6m FT8 JA run using WSJT-X 2.5.0-rc3 today. After the event, I copied the wsjt_log.adi file and uploaded the copy to my logging program, where I noticed a curious, deterministic pattern in the RST_RCVD column [Capture.PNG attached].
These incorrect RST_RCVD values were also in the wsjt.log file: 2021-07-16,22:37:00,2021-07-16,22:38:30,JA1OVD,QM05,50.315630,FT8,-05,-12,,, , 2021-07-16,22:38:45,2021-07-16,22:39:30,7K4DHB,,50.315630,FT8,-02,-12,,,, 2021-07-16,22:39:45,2021-07-16,22:40:30,JA0MVW,,50.315630,FT8,+01,-12,,,, 2021-07-16,22:40:45,2021-07-16,22:42:00,JR1BAS,,50.315630,FT8,-07,-12,,,, 2021-07-16,22:43:45,2021-07-16,22:45:00,JH1IIT,,50.315630,FT8,-08,-08,,,, 2021-07-16,22:45:15,2021-07-16,22:46:00,JA0DAI,,50.315630,FT8,-08,-08,,,, 2021-07-16,22:46:15,2021-07-16,22:47:00,JA7KPI,,50.315630,FT8,-05,-08,,,, 2021-07-16,22:47:15,2021-07-16,22:48:30,JH1PXH,,50.315630,FT8,-09,-08,,,, 2021-07-16,22:48:30,2021-07-16,22:50:30,JA9LJS,,50.315630,FT8,-08,-14,,,, 2021-07-16,22:50:45,2021-07-16,22:52:00,JI1RAK,,50.315630,FT8,-17,-14,,,, 2021-07-16,22:52:15,2021-07-16,22:53:00,JA9IPF,,50.315630,FT8,-08,-14,,,, 2021-07-16,22:53:15,2021-07-16,22:54:00,JF2WXS,,50.315630,FT8,-07,-14,,,, 2021-07-16,22:55:45,2021-07-16,22:56:00,JR7AIW,QM09,50.325630,FT8,-15,-12,,, , 2021-07-16,22:56:15,2021-07-16,22:57:00,JA2CXH,,50.325630,FT8,-10,-12,,,, 2021-07-16,22:57:15,2021-07-16,22:58:00,JA5EXW,,50.325630,FT8,-17,-12,,,, 2021-07-16,22:58:15,2021-07-16,22:59:00,JH1TWT,,50.325630,FT8,-05,-12,,,, 2021-07-16,22:59:15,2021-07-16,23:00:00,JM1SZY,,50.325630,FT8,-01,-12,,,, 2021-07-16,23:00:15,2021-07-16,23:01:00,JI1FLB,,50.325630,FT8,-18,-12,,,, 2021-07-16,23:01:15,2021-07-16,23:02:00,JJ1VKF/P,,50.325630,FT8,-16,-12,,,, 2021-07-16,23:02:45,2021-07-16,23:03:30,JE7ETY,,50.325630,FT8,-08,-12,,,, 2021-07-16,23:03:45,2021-07-16,23:04:30,JL1OZI,,50.325630,FT8,-12,-12,,,, 2021-07-16,23:07:15,2021-07-16,23:08:00,JK1GKG,,50.315630,FT8,-11,-12,,,, 2021-07-16,23:08:15,2021-07-16,23:09:00,JK1SQI,,50.315630,FT8,-07,-12,,,, 2021-07-16,23:09:00,2021-07-16,23:11:30,JH1HRJ,,50.315630,FT8,-05,-17,,,, 2021-07-16,23:11:45,2021-07-16,23:12:30,JL1QOC,,50.315630,FT8,-15,-17,,,, 2021-07-16,23:13:15,2021-07-16,23:15:00,JO7WXN,,50.315630,FT8,-16,-17,,,, 2021-07-16,23:16:45,2021-07-16,23:17:30,JI1DMH,,50.315630,FT8,-12,-17,,,, 2021-07-16,23:17:45,2021-07-16,23:18:30,JH6ETS,,50.315630,FT8,-15,-17,,,, 2021-07-16,23:21:45,2021-07-16,23:22:30,JH4LRH,,50.315630,FT8,-02,-17,,,, 2021-07-16,23:25:45,2021-07-16,23:26:30,JA6WJL,,50.315617,FT8,-15,-17,,,, 2021-07-16,23:26:45,2021-07-16,23:27:30,JA6RJK,,50.315617,FT8,-11,-17,,,, 2021-07-16,23:29:45,2021-07-16,23:30:30,JE6HJT,,50.315617,FT8,-04,-17,,,, 2021-07-16,23:31:45,2021-07-16,23:32:30,JH4IUO,,50.315617,FT8,-08,-17,,,, However, the values in the ALL.TXT file agree with the displayed values decoded in real time - i.e., they are correct. (I can, of course, send the file if desired.) Also, and perhaps most strangely, QSOs before and after the JA run have the correct RST_RCVD values logged. I could find no errors in the RST_SENT values before, during, or after the JA run.
