Hello Eddie !
Those files, that do not decode directly in WSJT-X, could be decoded if
replayed with a (round about) -1 second timeshift. Using the
"audacity"-program as a (time-shifted-) tone source WSJT-X (rev 2717)
did decode 1244, 1248, 1252 files correctly :
1340 10 18 -0.3 1408.93 0.00 G3ZJO TEST
(UTC is time of replay)
(Files 1246 and 1250 were almost "silence", i.e. no JT9 tones.)
The JT9-tones start at :
1244: 1.096 sec
1248: 1.080 sec
1252: 1.142 sec
after the begin of the file.
Maybe this helps locating the problem.

The usual happened to my local de-codes 6 or 7 transmit periods and they
fail to de-code.
Transmitter drift is noted as less than 0.75Hz in a 4minute RX - TX
period. After 7 decodes they failed, I assume the drift becomes more
rapid than the tolerance level over time.
The files are, 3 before 2 after de-code fail :-
