    The best digital mode is whichever one people are using and I can make contacts on. Lately the JT modes/FT-8 have been interest. I really need to get back on PSK31 though and perhaps try out Olivia. Hope to be on a few of the RTTY contests in 2019.

    "CW because no computer is required"

    CW isn't a Ham digital mode. Never was, never will be, no its not 0's and 1's ... Jeeze when will people give that lame comment a break.

    Just try to get DXCC by submitting 100 CW QSL's.

    The signal is ON or OFF. 1 or 0. It is digital. A "dit" is 1 a "dah" is 111. CQ is encoded as 111010111010001110111010111 Looks like digital to me!

    It may be digital but CW is not binary. It's trinary, 3 symbols: off, on, space. Can't parse it without that separator.

    Completely wrong! Thats like saying ASCII is not binary because there's dozens of symbols!
    There is only on or off. Sound or no sound. The length of each differs to convey meaning. If "1" is on, "0" is off. Just like "111" is dah, (3x dit) "000" is a space between letters and "00000" is the space between words.

    ASCII symbols can be represented by decimal and hexadecimal numbers. And by the printed characters. Nothing binary about it.

    Yes ASCII transmitted serially uses mark and space. And stop bits. And IDLE (NUL) characters.

    Think about it for a while.
