Multicast support to GridTracker

[EI4KF]

My scenario: JTDX and Swisslog on my Windows 11 computer and GridTracker on my networked Raspberry Pi.

What I have been doing: GridTracker will accept Multicast UDP messages from JTDX. I used IP 224.0.0.251 on port 2237 and it works as far as GT is concerned very well.
Unfortunately, only the Primary UDP Server in JTDX can be configured for Multicast. This means that a second and more limited server has to be used in JTDX to send log data to Swisslog. That works but of course I do not get the full features, the loss of which I have tolerated but now my tolerance has expired! 

What would really help, if it could be done, is for Swisslog Main UDP input to forward to GT using the Multicast addressing noted above. I have checked forwarding, entered the 224.0.0.251 on port 2237 but it is not received by GT and in Wireshark I do not see anything leave Swisslog on that port. I suspect therefore that Multicast is not implemented, not surprising really hi. I wonder if it can be?

It is not absolutely critical. All it means at the moment is that GT will not track band changes and I have to manually do that in GT. But it would be nice if I could have all 3 programs working together.
