[SFDXA] Digital Modes

[Bmarx@bellsouth.net]

Part of an ongoing discussion on another list. 

Which one will be popular with more and more new ones coming all the time? I hate to spend money on one mode only to have it get outdated. :-$
    Will one have become the standard like CW and SSB and RTTY?  Can one box decode these all or do you have to have multiple boxes. Of course all have different software.
    If you're into digital that's your thing. Just, lets play nice together!  :-):-)

    Found a list of Digital modes:
Amateur teleprinting over radio (AMTOR)
D-STAR (Digital Data) a high speed (128 kbit/s), data-only mode.
Hellschreiber, also referred to as either Feld-Hell, or Hell
Discrete multi-tone modulation modes such asMulti Tone 63 (MT63)
Multiple frequency-shift keying (MFSK) modes such as
FSK441, JT6M, JT65, and FT8

Phase-shift keying:
31 baud binary phase shift keying: PSK31
31 baud quadrature phase shift keying: QPSK31
63 baud binary phase shift keying: PSK63
63 baud quadrature phase shift keying: QPSK63
Frequency Shift Keying:
Radioteletype (RTTY) FSK
Other modes
Spread spectrum, which may be analog or digital in nature, is the spreading of a signal over a wide Bandwidth.
High-speed multimedia radio, networking using 802.11 protocols.
ROS is a Weak Signal sound card digital mode.[2]
JS8 is a new weak digital signal mode. The software 
JS8Call traces its origins to FT8. [3]
