Since I was such a skeptic before, I need to ask... How'd the 4' dish with
tracking work? I still can't imagine this thing being able to track the
balloon while in motion. I understand the math part, it's the opposing
forces of a 1 RPM Az / El motor system vs a bouncing, turning, wind
buffetted minivan. I know you guys do this all day long with big guns on
ships, but dishes on minivans?
Were you able to get a good lock on the signal and hold it?
