[Elecraft] Spectrum Analyzers, VNAs, antenna analyzers etc

[Robert Tellefsen]

Regarding the Autek antenna analyzers, M0RAC wrote "Has anyone built a
sturdy
slow motion drive for the tuning?  Let me know!"

Here's one idea.  Find the largest knob that will fit the little shaft and
the
space to the edge of the other knob.
This will give a modest improvement in tuning rate, due to the larger radius
of the knob.
