[Elecraft] RIT behavior when computer controlled / Possible Feature Request

Mark,

I believe the results of what you are seeing is dependent on the 
commands issued by CW Skimmer.  The KX3 can do as you request if it is 
given the correct commands (in the correct order).  You might want to 
ask the CW Skimmer folks to implement your request.
