      Hello Joe,

      MNI TNX for the guidance! I thought I would need to have people add it because TX is
      not included in the WSJT User Manual as an accepted international prefix.



      I know many stations are still using WSJT Version 6 and Version 7 because they
      think those versions are more effective decoding on their computers. If it is not
      necessary for ANY of those users to add TX5 to the special "DXCC Prefix" box on the
      SETUP/OPTIONS page, I will delete those instructions from my web page.

      I look forward to hearing from you regarding this issue with those versions, but I
      understand now that WSJT9 has no problem identifying TX5K properly. MNI TNX and VY
      73, Lance
