About plotting simulcast plots using Splat!. This is the only post I can see about this. Looking in the svn, I can see the simul.c file and various READMES and docos, but no real information on how to compile Splat! for this functionality. I'm also not a Linux buff, but I had a quick go at compiling and I got errors on a test Debian machine I had.
Has anyone gotten this working, or do you use an alternate like Radio Mobile? I've used Radio Mobile's online plotter, but this doesn't include simulcast support.
