I also see some strange behavior sometimes - only way to get it work again - is to go to the audio setting on the wsjt-x - do not need to do anything - just press ok - and it works again.
Sometimes it stops totally - then I go to the radio tab - and pressing Test CAT - all works again.
Tested using different USB cables etc etc but no differences.?
And I do not have this problem when using my Icom radio - and there is no RFI in my shack - and a good and stable 12V supply.?
But - the radio works great - except for this??
