Should the UDP Port and IP Address in JTAlert match the 2237 and 127.0.0.1 in WSJT-X ? Or have I messed those up as well?


What JTAlert UDP address & port are you referring to? If it is the Resend UDP settings, definitely DON'T change them to match WSJT-X, doing so will create a feedback loop with received UDP messages being sent back to the input ad infinitum.

An alternative to using 127.0.0.1, is to use a multicast IP address, like 239.255.0.1. See the JTAlert Help File, "WSJT-X / JTDX UDP Setup" topic (at root level of the help).
Missing in that help topic is the need to set JTAlert to use multicast on the loopback interface, via the "Settings -> WSJT-X UDP Multicast on Loopback" menu, make sure it is ticked. AND, due to recent changes in WSJT-X 2.3.0 is the need to ensure a loopback outgoing interface is selected in the UDP Server settings.

eg  my WSJT-X setup.
