[Boatanchors] Mica compression trimmers?

[McDonald, J Douglas]

Its all a matter of degree.

I've seen such things with two adjustments: one for capacity,
one for temperature coefficient, which goes through zero. That was done with
a bimetal strip.

Subject: [Boatanchors] Mica compression trimmers?

Resolved: For any receiver local oscillator which uses Mica compression trimmers, thermal drift is inescapable. Debate?
