[Elecraft] K3 SHUTDOWN.

[Dick Roth--KA1OZ]

I noticed that you said you were running at 100W.  That may be your
problem.  RTTY is a 100% duty cycle mode and I believe your rig may be
overheating to the point of self-protection (shutdown).

When I run data modes, I normally reduce power to 25W.  I have never had
the same problem you describe.
