> So what does that conclusion mean about when the probe will be so far away that we are below the Shannon limit? I think the practical limit right now is that the Voyagers are losing power. "The radioisotope thermoelectric generator on each spacecraft puts out 4 watts less each year. [...] The two Voyager spacecraft could remain in the range of the Deep Space Network through about 2036, depending on how much power the spacecraft still have to transmit a signal back to Earth." https://voyager.jpl.nasa.gov/frequently-asked-questions/ https://voyager.jpl.nasa.gov/frequently-asked-questions/
