New in version 2.16:
  • First, keep your previous version, make backup copy of previous log file (mshvlog.edim) before installing ver. 2.XX.
  • Added: In "Interface Control", "Selected Constant TX Audio Frequency FT8" . In this function, for clearer RIG RF output, users have the choice to use constant frequency between 1200-2500 Hz. If the function is active during TXing, application frequency display color is red.
  • Corrected: In mode MSK144 +Sh, not possible to emit RR73.
  • Corrected: PI4 decoder synchronization from -3s to +3s.
