WSJT-X 1.7 issues

Whilst WSJT-X 1.60 works very well with CAT control, version 1.7 can have grave problems. The development of the WSPR Challenge ( has drawn attention to the severe database corruption that 1.7 can produce when the CAT looses sync with WSJT-x. You only have to look at the results of the band rankings to see that there are very odd scores that are due to cross band contamination.

It is a great pity that a few stations are still using a development version regardless of the mess they are making of the database when the stable 1.6 version is trouble free.
