Steve,

Since WSJT-X uses UDP, there is a chance that you can get more than 1 listener 
to receive all UDP packets. According to this article, if all clients bind to 
the port using SO_REUSEPORT (and possibly SO_REUSEADDR), all listeners will 
receive all datagrams. You may have to convince the author of JTAlert to also 
make this change if it's not already set.

Alternatively, you could write a simple listener that repeats all packets heard 
on several ports.

Is there any way without hacking the code to enable a second UDP port? I'm 
writing a little C# windows app and need to read the UDP messages, but still 
want to keep JTAlert running.
