Reply to comment by teh_maxh in ELI5: Morse code is made up of dots and dashes. How did telegraph operators keep from losing track of where one letter ended and another began? by copperdomebodhi

absolutely, if I was on a duplex circuit (two freqs) the receiver would send a dah, for every word received correctly, and if he wanted it resent, then send a ditdit.

People are lazy, so didn't really have to use Q codes in that situation, you just increased your send speed until either you weren't comfortable, or the receiver started asking for lots of repeats.
