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.
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!
