[Elecraft] KX1 receiver alignment?

[tedwb3avd at netzero.com]

Greetings,
Have just finished phase 2 testing of my KX1--all seems well. One question I have with regards to adjusting the tunable capacitors CA, CB and CC. These have ranges of 8-50, and 5-20pF. Upon rotation, the peaks are apparent. Is the proper procedure to traverse the entire range of the capacitor to find the strongest peak, or is one or two rotations of the slug sufficient to attain peak receiver performance?
Thanks. Ted.
