[Elecraft] K3S Shift Setting for WSJTX

One anomaly which I've just observed with my K3S.  I did set the 
software as suggested for SPLIT mode for WSJT-X / JT-65.   The radio 
followed as expected.   I made a few contacts successfully with this 
configuration.   When I closed WSJT-X I noted it left the radio in SPLIT 
mode.   I can just see all of the confusion and frustration not to 
mention unintentional QRM created by this occurrence.   Another trap to 
watch for.

Probably in my case, even a better reason not to use SPLIT.   In other 
words, it isn't idiot proof and I've been accused as being as dumb as a 
box of rocks.
