VCXO frequency isn't high enough

Try going smaller than 10 pF (you can put a 10 pF fixed capacitor in

I did this and it will go slightly higher in frequency, but it gets a tad
unstable (could be the counter too, I wish my new scope would get here). I
guess I'm at the limits of that particular crystal.
