HI ! My opinion: I have also tested this some time ago running both programs in parallel with same linux PC, same rig IC7300, OCF dipole 80-10m. If wsjt-x decode is set to "Normal" or "Deep" I would rather say "slightly better, in some cases". But difference is so small that it did not cause

After this past weekend's ARRL VHF contest, one of the top SOHP scorers, Mike, W3IP, posted a note to the PVRC reflector along with the breakdown of his score. In his comments he compared the FT8 sensitivity of WSJT-X vs JTDX. Mike is a technically sharp guy and I trust what he has reported. Here

Could you send me a randomly picked up subset of the JTDX exclusive decodes together with a time stamp? I have a live data feed from pskreporter for a visualization project and I can verify wether other stations received it and what they were running. I've got mostly solid data for the last

Michael, have you looked at the hint code that was added ... its a bunch of 'if then' decision trees, which can explain the 'extra processing'. As a user, I'd rather trust the 13K WSJT-X decodes to be REAL, rather than the 15K of which 2 or 3K may be spurious. Neil KN3ILZ On 6/11/2017
