      How much better are MIL-STD-188-141A and/or ALE400 than PSK63 or PSK 125
      with FLARQ?

      Speed, robustness, use for HF E-Mail, etc.

        Maybe better, maybe not BUT ALE (not so much ALE400 which is ham-only)
        is an international standard that is implemented in many military,
        paramilitary, commercial land-mobile and maritime radios and systems
        as well as a growing number of ham situations, particularly those in
        emcomm where inter-operation with non-amateur assets is necessary(e.g.
        NGO's, government agencies, SHARES, USAF Auxiliary, USCG Auxiliary,
        MARS etc.). Although there are features in the ALE standard that allow
        message/file transfer, it is primarily used to establish a "right-now"
        sked between stations on the most-favorable frequency band (using
        short text messages or auto tuning)and the communications between the
        stations are then carried out using the most appropriate mode, whether
        voice or digital (or even CW if you wish!).

        More on ALE at http://hflink.org

        There are currently NO implementations of ALE on Linux/BSD/Unix - only
        on Windows or built directly into radios. Since fldigi is sort of a
        Linux/BSD/Unix "Swiss-Army Knife" of digital modes (sort of like
        MultiPSK in the Windows world) it seems like an ideal candidate to
        have an ALE addition - especially if the resultant communications use
        one or another digital mode - including the ones you mention.
