MacLoggerDX users note:

GridTracker offers a UDP relay facility, and you can use this to have GridTracker receive and inspect UDP packets and display its map, and then send the packets on to MacLoggerDX for further processing.

In GridTracker, use the Settings panel to set the UDP listening port to 2238. Turn on UDP forwarding, and set the destination port to 2237. Leave the IP address at

Then, in WSJT-X Preferences, in the Reporting tab, set the UDP server port number to 2238. Leave the UDP Server IP address at

That’s it. WSJT-X will send received data to UDP port 2238, where it will be inspected by GridTracker and then forwarded to port 2237, where it will be picked up as usual by MacLoggerDX.
