[AMRadio] NC300 Oscillator Tracking Nightmare

[Gary Schafer]

With any oscillator, to get both ends right you need to adjust the
capacitance at one end and the inductance at the other end. If it is
spreading out too far , over compensate a little at each end each time
you make an adjustment. Actually if you have an error of say 20 kc on
one end, adjust for an error of 10 kc in the opposite direction. Then do
the same at the other end of the dial. Several tries will get you there.
