Installation of the beta ACL seems to have gotten it working. Need more contacts to be sure.

By ACL listener I assume you mean the ACL program itself? It has been working fine with the FT modes using WSJT-x. Would there be any difference in the settings? Thanks

Well it appears to work and it says at the top that it posted to ACL. But the data did not populate in ACL. Any other thoughts?

I have the same issue including not being able to attach a snip file image.
