<DIV><FONT size=2>I just finished my first VCO on a protoboard and I actually
works :)))! It is really a prototype because I haven't decided, which IC I will
use for exp. converter. I'm thinking of CA3046 (currently CA3086) with heater,
because this is cheap solution. The second option would be LM394/MAT-02. How
much is the second design better (for exp. conv)? I've seen that heated CA3046
VCO leave out tempco's. What about heated LM394 (Rick Jensen's design)? Any
recommendations will be appreciated! Anyone compared the designs side by side? I
would like to choose the most stable design before I begin to work on a PCB.

<DIV><FONT size=2>The second question is: what exactly does the SOFT SYNC
option? Theoretical explanation wanted, not just that it provides more complex
waveforms that single oscillator and that it requires two of them
(osc's).</FONT> </DIV>
