Download Mark V program description
Version changed to 6 on September 26, 2018.  Changes include:
Version changed to V5.7 on January 28, 2018.  Changes to K2 simulation to
support WSJT-X.  Allows you to run the FT-1000MP Mk V in split mode.

Version changed to V5.5 on December 21, 2017.  Corrected this problem:
If VFO-B had a different mode from VFO-A, NaP3 was slowly shifting between the two modes. 

The download version was changed to V5.4 on November 16, 2017.  Daylight
savings time is now automatic.  Various bugs fixed.  Known issue: sometimes when the Windows system has been rebooted, MarkV will not start the first time
you hit RUN.  If that happens, close the program window and try it again.

The download version was changed to V4.2 on April 7, 2016 at 3:50 PM.  Commands from an application to the K2 to go split frequency were not always being carried out correctly.  This problem has been fixed.

The download version was changed to V4.3 on April 12, 2016 at 6:35 PM.  The port activity indicators were changed so they flash green if the port is active, and are solid red if the port is inactive.

Download version changed to V4.4 on April 23, 2016 at 7:30 PM.  In some cases, the mode was not being set properly when mousing on a spot in the logging program.  Now the mode is properly set for both simplex and split situations.
