Alan Wolke Explains Varactor Diodes

As always, a very illuminating presentation by Alan.  I wish my oscillators were that stable!
And I couldn't help thinking how much simpler this circuit is in comparison to the DDS devices we've been talking about.

  1. Bill - the oscillator isn't *that* stable. Being open and unshielded, it varies a lot with surrounding objects. If you listen to it on a receiver - it sounds like a Theramin when you wave your hand around it!
