Interestingly, the NASA Voyager 1 spacecraft is downloading data to Earth at the same 160 bps rate over X-band as the Parker Solar Probe, but using the larger 70m dish at DSN Madrid and a larger 3.7m antenna on the spacecraft.

However Voyager 1 is 24.9 billion km from Madrid, 157 times farther then the Parker Solar Probe.

Receive power = 10^-22 kW for both spacecraft.
