[Elecraft] Shutdown on 50MHz CW

[Dave Zeph]

I've observed the same behavior on 6M - into a Dummy Load.  Holding TUNE and
near Full Power Output, with the SWR Display reading 1.0:1, I suddenly hear
a relay click, the display changes to read HIGH SWR, and the Output Power
drops to 0.   Taking the K3 out of TUNE and then immediately returning to
TUNE briefly resets the K3 to normal Power Output before the behavior
repeats.  

 

This also happens with a low SWR antenna as well.  In either case, it makes
no difference whether the ATU is in-line or Bypassed.
