[Elecraft] K2 12M odd behavoir, "END" message -- swl autotune?

[Oliver Johns]

Don,

This brings up something I've wondered about.  If the K3 will not  
transmit out of the ham bands, how do you get the autotuner to align  
the impedance match for optimal out-of-band swl?  It has to be that  
it will output slightly when "tune" is pressed, just enough for the  
autotuner to read the forward and reversed power and make its  
decisions.  Not so?  Is that what it does?

73,
