I have worked a lot of FT8 and FT4 with wsjt-x with no problem, so I thought I would look into the JT modes. (I'm using a Rigblaster Advantage interface.) When I go to the MODE tab and click on JT65, everything seems to come up properly, I get signal indications on the waterfall display and the system clock is accurate, but I'm not decoding anything. Any idea why not? If I switch back to FT8, everything's normal and functional.
