Okay. Sorry. "Carrier" is the wrong word. The radio reciever captures
and demodulated 2 GHz waves as if those waves are amplitude-modulated.
So this "carrier" is really the waves emitted from cosmic sources.

Okay.

Wouldn't I hear sounds resulting from demodulating the 2 GHz waves in an
AM-manner?
