More ramblings about VCDO...

[Tim Ressel]

Sorry, Don. I didn't mean to re-open that discussion. To clarify, When I said
"perfect" I was referring to frequency stability. You're right of course,
nothing is perfect. NCOs have certain advantages that make me want to explore
them. I am also building a nice little analog VCO. As you can see, my Libra
nature is showing  ;)
