Well now, I'm onto bigger and better things.

I was doing a bit of reading lately and came across some interesting
topic one being VCO. The VCO I saw used a Optical Shaft Encoder
(OSE). The setup used was rather odd looking to me and didn't look
that mechanically stable.

Could someone explain VCO to me? And, also what type of VCO would be
the best in a transceiver considering the technology of the past 10
years? Are there digital VCO's?
