It's all we can do to pick up the Pioneer space craft signal with our largest antenna and it is only a few billion miles a way or about 1/1000th of a light year.

Yeah, but Pioneer's transmitter is only an 8 Watt source. Presumably if you had the energy to move a giant starship at a significant fraction of the speed of light, signal strength would not be an issue.
