Nothing more than a couple of (somewhat legible) diagrams. We drew up a convoluted system that relied on an antenna rotator, directional antenna, GPS, and a bunch of cron jobs in Linux.
I might add, none of us really know what we're doing, radio-wise, we were going to learn on-the-fly ;) Can't remember what the GPS was for, though. Probably made sense after a few beers...
