@KY4JLS While i’ve used it in the past I’m not that familiar with log4om. The most likely reason this is happening is because you have both log4om and the WRL cat control listening on the same UDP port and its only sending to one. You’ll need to set the secondary UDP port settings in JTDX to send on a different port and then set the WRL Cat control app to listen on that other port or set log4om to resend the QSO data out from log4om to the WRL cat control UDP listener.
Below is a link to setting up the cat control app, jtdx/wsjtx and grid tracker. That might help somewhat.
