Odd behavior when offset for wsjt-x is greater than 3k...anyone else see this?

I've been spending a lot of time using WSJT-X for JT-65 and JT-9. Enjoying digital modes more than I anticipated.

I've noticed that every so often when the offset is greater than 3k the flex will show the red TX transmit, however in the waterfall it shows no signal and nothing noted in panadapter either.

Here is what SmartSDR looks like during this event

Anyone else notice this behavior with WSJT-X and SmartSDR?

    Set your TX High Cut > 2900 (e.g. 4000)!

    What Cedric says and don't forget to setup a JT65 profile otherwise it will be a recurring problem. I tend to forget to enable DAX as source on transmit when bouncing from JT65 and SSB modes.

    Another fix for this is to use the fake split mode of WSJT-X, this will automatically increase or reduce the frequency enough to keep the transmit signal at around 1.5k and return to the correct frequency on receive.
