The difficulty of long range communications is nicely demonstrated there: "X-band with 5-m fixed antenna capable of sufficient downlink (~10 Mbit/week) at 1000 au using Next Generation Very Large Array or equivalent resource" ... "Two Next Generation Radioisotope Thermoelectric Generators for 300 W
(electric) at end of mission"
So with twice the area of radio dish and a power supply that after 50 years is still double what Voyager launched with, the data rate will be two bytes per second.
