Multicast support to GridTracker

[EA3GCV]

Hello Erik,

Thank you again for your detailed response. What a pity that UDP messages from the GT on the PI are not reachable to avoid using the GT on Windows as "gateway". At least you have found out a solution! Why UDP messages from the PI can't be read in Windows? Have you tried to disable Multicast in GT then enable forward from GT to the Windows 11 IP? Maybe you don't need Multicast at all. I remember having issues enabling Multicast in GT in some of my testing.

I'm also thinking that if the 2nd JTDX server feeds properly GT, then you could use this second server perfectly as input in Swisslog (used as main instance to get all the benefits). I will test but second server should send exactly the same UDP messsges as first server.

I will release the new country table as soon as you send it to me. Thank you for your excellent job maintaining the country table!
