[Elecraft] K3 - qsk keying loop

[Don Wilhelm]

Barry,

Something was added to provide a "TX inhibit until PTT" function.  That 
discussion was late in the Field Test cycle.  I was involved on the 
sidelines of the discussion even though I was not a field tester.

The bottom line is that it is "in there", but I have not combed the 
latest documents to determine where it is.  Look through all the menu 
items related to keying.
