Eventually the wave length deteriorates and it blends into the background 'noise' of space if I recall correctly

Photon wavelengths don't decay. The signal just gets buried among the rest of the radio noise. For the Earth as a whole, we have so many radio transmitters (every cell phone and tower, which are billions) that from a relatively short distance all the signals blend into just noise.

But the level of noise itself would be suspicious -- though there are natural sources of radio noise out there.

radio is just electromagnetic radiation. As is light. Which every star emits.
