[ARC5] Transmitter capacitors

[AKLDGUY .]

Hi Roy

Yes, I understand the requirement for stability, especially in the VFO cap.
Something just occurred to me.
Maybe the plates are not there to add rigidity. Maybe they're designed to
expand and contract to the same extent and at the same rate as that side
of the capacitor frame, so that the shafts don't bind in the studs. If the
plates weren't there, extreme temperature changes from ground level to
20,000 feet would tend to result in bending of the capacitor frame and
binding of the shafts.

So my thinking is the opposite of rigidity. Deliberate expansion. If this is
right, the shape of the plates is not simply random, they were made with
great care, perhaps after lots of experimentation.
