[Elecraft] K3 Power calibration failure

[Don Wilhelm]

  Brian,

I am relpying out of "stupidity".  The K3 Utility tries to set the ATU 
to bypass.  If it detects the KAT3, but it does not go into bypass, that 
would terminate the procedure.

I suggest that he look at the KAT3 situation first.  Once that is 
resolved, then other factors will either fall into place or will present 
themselves as  a different problem.

73,
