Imagine the sensitivity of the instruments needed to detect that signal from Voyager.
Is the signal being received by the Hubble, one of those huge antennas on Earth? Curious.

The Hubble Space Telescope senses near ultraviolet (300-400 nanometer wavelength), visible light (300-700 nanometer wavelength), and near infrared (750-1400 nanometer wavelength). Nothing to do with Voyager, nor other spacecraft.
Voyager 1 receives commands at a radio frequency of 2100 MHz, and sends responses at 2300 MHz and 8400 MHz. NASA’s Deep Space Network receives Voyager’s transmissions: antennas are all on Earth’s surface, at Goldstone (near Barstow, CA), near Madrid, in Spain, and near Canberra, in Australia.
