[Elecraft] K3 RF Gain calibration

[Ian Maude]

OK, here is the heads up.

Mea Culpa (as usual :) )

What I had done before was to use CWT and spot to zero beat the signal from
my XG1 and then switch off CWT.  I now assumed the signal was centred.  This
does not appear to be the case.  I tested this with all 3 versions of the
Utility and got the same result.  Then I did it manually, centering the
signal by ear et voila!  It now looks and feels right :)
