Hi Mike,

that's not quite the full story. Any application can send UDP datagrams to a multicast group address, no special coding is needed. The server end(s) is where the multicast group has to be joined and that does require extra coding over a basic unicast UDP server. It is not a language limitation although the support libraries for a language may not include joining multicast groups out of the box, but writing the required code is quite feasible if the underlying system network supports it (Windows does).

Bill,

What is the Multi-cast group address used by WSJT-X. I expect it is somewhere within the standard 224.0.0.0 through 239.255.255.255 range.
