[Elecraft] WSJT-X Problem with K3S

[John Stengrevics]

Many thanks to all who provided their suggestions.

I decided to try Joe's (W4TV) suggestion and elect RTS.  That appears to have solved the problem of the transmit staying on.

My only remaining problem is a 100 to 200 millisecond spillover into the next sequence.  I have synched my Mac to time.nist.gov <http://time.nist.gov/> and the time.is <http://time.is/> site shows that I am dead on.  If anyone has any suggestions, they would be much appreciated.

73,

Many PC station programs like N1MM+ can add transfer delays only where they apply, as do WinKey equipped devices which can apply CW key speed related "word space" intervals.
