Can you pick up radio in space?

Name: Ken, Herne Hill
Qualification: Former sound engineer
Answer: The signal is related to the amount of watts you pump the signal out. So you could broadcast to space if you had enough power in your transmitter. But the aliens would need a responder to translate the radio wave into sound.
