When I was a teenager and a ham radio operator we would have fun by tuning into Voyager and other transmissions. It was doable then even with hastily constructed directional antennas.
If I remember correctly, the Voyager radio is about 25 watts. With good antennas, that is easily enough for EVM space, except during conjunctions. However, from 11 billion miles away, as SC says, that takes something with the sensitivity of the DSN. From: Steven M.

So the real issue would be hacking the ground-stations to get access to the equipment... unless you have a global array of 30+ meter dishes lying around. http://en.wikipedia.org/wiki/Deep_Space_Network -sc From: Crawford, Scott [mailto:[email protected]] Sent: Friday, March 22, 2013 11:37 AM To: NT System Admin Issues Subject: RE: Space and Beyond: Cool. Has me wondering if amateurs could tune in to the broadcasts from Voyager. Also, I'm not sure how much instruction it receives, but it seems like there could be some interesting hacking opportunities. How secure could 35 year old technology be? From: Andrew S.
