I have a problem with installing JTAlert 2.16.12 and JTAlert 2,16.13.
The two most common causes of JTAlert to not receive UDP traffic from WSJTX and thus producing the error shown is
I strongly advise that you abandon the use of the 127.0.0.1 port 2237 UDP server settings and utilize a multicast IP address, like 126.96.36.199 on port 2237. Other WSJTX interaction applications like DX Aggregator and Grid Tracker will need to be set to use that multicast IP/Port. There is no setting needed for JTAlert as it will automatically adjust to the new multicast address.
Using multicast will allow multiple applications that interact directly with WSJTX/JTDX to run concurrently, provided they support multicast without adversely affecting the other applications, something that is not possible if using the unicast 127.0.0.1 address..
