Default Re: The Best GDO Ever Made?

In Heathkit's tunnel diode based dip oscillator, which I'm cloning, the dip is measured in terms of a change of the voltage on the tank circuit, sensed via a small (3pF) capacitor. Guess that will be either just a DO, or a TDDO.

I see that there is a lot of effort currently going on to incorporate tunnel diodes in to the gates of FET's, hence TFET's. Glasgow University are currently publishing papers on TD's; curious.
