[R-390] Excessive backlash in BFO pitch control

[Tim Shoppa]

One of my IF decks has excessive backlash in the BFO pitch control.
e.g. if I'm turning to the right, it zero beats at "0", but if
I'm turning to the left, the zero beat is closer to "+1".

Mechanically, I see an accordion-type coupling between the shaft and
the reactor.  Is this where I should be concentrating my effort, or should
I be looking inside the variable inductor itself?

Alignment between all the shafts is less than peachy, too.  But I
cannot see how this would give more than a tiny bit of backlash.

Tim.
