They are powered by RTG's. The plutonium in them will be used up.

It would be interesting to know what equipment they are now using. It would also be awesome of we (non-nasa people) could pickup V'gers signals on "homemade" equipment Just like the amateur radio operators could pickup the signal from Sputnik.

The radio communication system of Voyager 1 was designed to be used up to and beyond the limits of the Solar System during the extremely long flight of this space probe. The communication system includes a 3.7 meter diameter parabolic dish high-gain antenna (see diagram) to send and receive radio waves via the three Deep Space Network stations on the Earth. These modulated waves are placed in the S-band (about 13 cm in wavelength) and X-band (about 3.6 cm in wavelength) which provided a bit rate as high as 115.2 kilobits per second when Voyager 1 was at the distance of Jupiter from the Earth, and many fewer kilobits per second at larger distances.

When Voyager 1 is unable to communicate directly with the Earth, its digital tape recorder (DTR) can record up to 62,500 kilobytes of data for transmission at another time.[11] The length of time needed to send messages to Voyager 1 or to receive messages on the Earth depends on the straight-line distance between the two according to the simple equation t = D/c, where D is the distance and c is the speed of light (about 300,000 km/s).
