WSJT DX Aggregator - Multicast configuration

WSJT DX Aggregator is a program that allows the stations using the WSJT-X or JTDX programs to automatically upload DX reports to DXMAPS so that they can be shown on the  maps, listings, etc.  

Since version 2.0 it can join a multicast group that is the way that WSJT-X implements to share its messages between several programs. In this way all programs that joined the WSJT-X multicast group will received a copy of the messages.

This page is intended to explain how to configure WSJT-X and the DX Aggregator only when multicast is required.  The basic configuration is explained in the main DX Aggregator page.

Enter in DX Aggregator the same port and multicast group that is configured in WSJT-X

If all is OK you will immediately see the frames received in the "Raw message received" box. Otherwise it means that the UDP port configured in WSJT DX Aggregator and in WSJT-X/JTDX don't match. Please notice that port 2237 and multicast group used in this example can be any available UDP port and group in your system.  Just make sure that it is the same that you have configured in WSJT-X/JTDX for sharing the data.

Leave the program running (you can minimize it if you want). As soon as it detects a CQ or QRZ message it will automatically spot it to DXMAPS.

In WSJT-X go to "File - Settings - Reporting" to configure the UDP port and multicast group, as show below.

JT-Alert users: When JT-Alert is started it blocks the use of the UDP port, so that no other applications like WSJT DX-Aggregator can use it concurrently. However version 2.12.4 of JT-Alert implements a port forwarding option that allows to use both programs at the same time.  To do that you must configure JT-Alert to rebroadcast WSJT-X frames on a different UDP port and configure WSJT DX-Aggregator to listen on that port. In the below example it has been configured to rebroadcast on port 2334.

WSJT DX Aggregator has been tested with the release versions 1.6 to 1.9.1 of WSJT-X.  Also with JTDX 17.7, although it will eventually work with other versions.
