      Hi all

      Some of you probably know this, but Patrick f6cte has made a KISS mode
      for APRS done in 141A (ALE) or ALE400.

      I am on 14094 +1500Hz in ALE400/KISS and using APRSIS32 .
      Try to connect .


      I am cross posting a mail from Patrick with a link to the beta of Multipsk.
