[time-nuts] Early WWV Oscillator

[Bob Camp]

Hi

The circuit in the app note is essentially a 1930's idea. The performance they are showing is related to the very small size / low mass of their oven rather than it's high performance. An oven large enough to do any good with a TBolt would be a very different creature.
