          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.
