I am new to JTAlert.
I am using (or trying to) version 2.16.14 with Windows10, JTDX and Log4OM.
I have followed 2 different tutorials, but my JTAlert screen remains empty ! I do not care about the sound alert.
It does communicate with the log : the test within the Log4OM menu is passed OK.
Obviously, I am missing something. The port numbers seam to be OK, according to those tutorials.
What else should I check ?

Thanks + 73

The JTAlert help file contains the setup instructions , they are very simple.

Likely you have Log4OM configured to directly interface with JTDX and it has taken exclusive control of the UDP server port preventing JTAlert from receiving the UDP data from JTDX. You posted error message indicates that you are not using multicast for the JTDX UDP server further suggesting that Log4OM is taking exclusive control of the UDP port.

I suggest you get the JTAlert - JTDX combination working first then bring Log4OM into the mix.

See the "WSJT-X / JTDX UDP Setup" topic. I strongly suggest you use a multicast IP address like
Followed by the "Settings -> Logging -> Log4OM V2" topic.
