Multicast support to GridTracker

RE: Multicast support to GridTracker
Hello Erik,

If your data flow is:

JTDX > Grid Tracker > Swisslog

Instead of enabling the second UDP server in JTDX to send QSO to Swisslog, in Grid tracker enable Forward UDP messages to another port (i.e. 2238) then use this port as input in Swisslog. Of course under this scenario you will always have to use Grid Tracker to log QSO from JTDX. Which features are you losing in Swisslog using the second UDP server? using the GT's forwarding option should work perfectly as well.

The forwarding option available in Swisslog only works to forward data on an not already used IP/port. Because you are forwarding data on the same IP/Port used by JTDX that's the reason you won't see anything in GT or Wireshark.

I have revised all options in the UDP component used in Swisslog and there is no Multicast option. I'm using the best component available for the Delphi D6 compiler. However, there is an option (already enabled) which allows more than one instance of the component to be active on the same local port. That is, sharing local port with other applications. But this doesn't work for forwarding only to receive data.
