[time-nuts] Restoring GR 1120-AB Frequency Standard

A capacitance bridge using a transformer would be a lot more stable than merely using the capacitance to vary the frequency of an LC oscillator.

The advantage of a capacitive sensing technique over a light beam is that it has much simpler and potentially more stable mechanical system than when a the mercury colum interrupts a light beam. Unless of course on has the Mercury column move a moire grating or similar setup such as making the top of the mercury column a reflector in an interferometer system.
