    I never tried AMTOR, it sounds like an interesting mode. Here it says that you need a PK-232 which I do have sitting in the basement somewhere.

    and you can also do AMTOr with a sound card. Multipsk has an interface.

    I agree, CW is definitely digital.

    And has had decoders of many types/ like lights connected to RX flashing Longs and shorts.
    You don't need a computer to have some kind of digital to analog decoder. It could even be a hole bunch in paper type decoder.
    Like ticker tape. Many types of paper wheel type decoders were used on a telegraph/ ticker tape and in RF CW.
    Many things were called computers/ decoders/ modems, before they become electric devices.

    Look at the German war code machine.

    On and off, dots and dashes, 0 and 1, Longs and shorts and with many ways to decode it. Which can simply be a flashing light or a sounder.
    How do you think a deaf person used to decode CW??
    Some of us are old enough to remember the old WE3 code practice machines that used paper reel to reel tape to send out the code for practice.
