VCO Coarse and Fine wiring.

VCO Coarse and Fine wiring.

2006-10-12 by brownchonald

On the schematic and connections diagram, I only see a place for one
"Tune" pot. How can I wire this so I have a coarse and fine tune pot?

If you want an even finer tune pot, add another 100k pot, with one end to
+15 and the other end to -15. To the wiper connect a 4M7 resistor. Connect
the other end of the 4M7 resistor to the CVSN pad.

Thanks Ken.

Now I've to figure out the square wave problem.
