Ham radio operators receive signals from Voyager 1 on Dwingeloo telescope

We have used the historic Dwingeloo radio telescope to receive signals from the Voyager 1 spacecraft. Only a few telescopes in the world have received these signals, which are very faint due to the distance of Voyager 1: almost 25 billion kilometers, more than four times the distance to Pluto.

Designing a Home Radio Telescope for 21 Cm Emission
(arxiv.org)
This study presents the methodology for creating a cost-efficient radio astronomy telescope that can be used to detect 21 cm emissions (1420.405 MHz) and determine the distribution and kinematics of neutral hydrogen specifically in the Milky Way.
