Even though radio travels "very fast" ...300,000 km/s (186,000 mph) the speed is finite. As I said In my previous post...the satellite is located 34,500 km (22,500 mi.) above the equator. That makes for a round trip of 75,000 km (45,000 mi). Even at the speed of light, this makes for a significant delay!)
