Cannot get WSJT-X and Log4OM to Sync!

Good evening,

I have tried multiple times to get wsjt-x to work with Log4OM. I have no problem with my Flexradio 6400M connecting, but when I try to add to the connection the UDP for JT-Alert, it will not keep the connection active. Plus, I do not get the little message below saying that WSJT is Port 2237. I have watched different video's and did what they instructed, but to no avail whatsoever. It was much easier connecting WSJT to DX Lab then Log4OM. Does anyone have any instructions that might help?

Mark Griffin, KB3Z

    Here are the settings that I use Mark. See if they work for you. I still haven't gotten Log4OM to report to QRZ and LOTW like it used to since the new "improved" UDP function was introduced.

    To get log 4 om to work you need to delete the udp connections then re-install using the add button in the program. There is a write up on it. I had the same problem. I have JTDX, Jt Alert, Gridtracker and Log4OM2 all talking to each other properly.

    The Internet is a big place. Can you provide a link?

    User guide updated and ready for users todownload.

    If a user need s to re-establish a UDP connection due to the recent changes in Log4OM the process is as follows

    1. Make a note of the port number and connection type already in use

    2. Delete the existing UDP connection

    3. Select a new connection eith by using the preset buttons or manually - Ensuring the port numbers and connection type noted in item 1 above are employed

    4. Save the connection 

    5. Restart Log4OM and the connected software
