Hauptsache, es gibt immer was zu Maulen! Vielleicht sollte man zur Erklärung mal das ganze Posting hier zitieren:

Its present distance to the Earth is about 17000 million km (3.5 the distance to Pluto) and the transmitter power is only 18 W. To give you an idea, their radio waves need 15.5 hours to cover that distance.

The backends normally used for Radio Astronomy are not adequate for the detection of narrow band communications signals so the Perseus did the job for me. For those curious, I have included some waterfalls and audio in the files section with the detection of Voyager 1 and Venus Express (much stronger).

Perseus-Besitzer können sich übrigens das Perseus-File herunterladen und das mal mit ihrem Perseus selbst anhören:
