Maybe in centuries *Morse Code* won't  be used any longer,  but *CW* is just
too useful for narrow bandwidth, slow signalling, human demodulated signals.
I know phase modulation can just about pull  information (signals) "out of a
hat" ( S/N ratio darn near unity [or less (?)] ), but CW is simpler.

Maybe you will want to use a simpler binary code?
