Voyager 2 is 20 billion km away now, and transmits data back at a strength of 23w (about 8x that of a typical mobile phone). Inverse square law means that by the time it reaches us, the signal is down to 1/10th of a billion trillionth of its broadcast strength - but still it can be detected and worked on. That's pretty mind-boggling. As is the fact that it's still working (to some extent) after 46 years in this less-than-friendly conditions of space...
Signals sent to it have an easier time, starting off at 400kw.
