Nice concepts on the FSK. An interesting historical note is that Morse code was originally intended to be read by eye. It was printed onto paper strip and read off that. They then discovered that the telegraphers learnt to decipher the sound of the relay/solanoid that did the writing and hence they phased out the printing side of it. Nick G4WHO (back to lurk mode)
