All radio communications are encoded, by necessity: radio doesn't carry mechanical longitudinal waves, so in order to represent them in the electromagnetic spectrum one needs must use a pre-agreed encoding. It could be amplitude modulation, frequency modulation, some sort of digital encoding, whatever. (And the very idea that a space faring civilization would use Morse code instead of a reasonably modern encoding is, I suppose, to be taken as irony.) | |
