[Elecraft] K2 meter alignment issue

[Don Wilhelm]

Mike,

That means you have some problem with U2 or Q12.  Something not 
soldered?  D1 not installed correctly?
Once you make those checks, if you find nothing incorrect, I can make 
some voltage measurements for you.to compare.
What value did you get for the CAL S LO parameter?  Something in the 175 
to 190 range is normal.  CAL S HI will normally be in the 18 to 25 range.

73,
