Do those devices actually provide a  reduction drive? From the pictures
I've seen, the just look like a turns-counting knob as would be used
on a multiturn pot.  If the standard pot knob, they would provide a 1-100
scale over 360 degrees of rotation, thus allowing the BFO to be returned
to a precise setting, but not a gear reduction.
