VCXO frequency isn't high enough

Doodling with reactance formulas, it appears that 20uH (coincidence?) would offset 100pF of capacitance fairly well by having a an opposing reactance (well resistance at this point) of about 450 Ohms at s/.well resistance at this point.// It's just inductive reactance, I need more coffee. ;-) 3581kHz, the same as 100pF. I'll try putting the coil I made in parallel and see what happens. Hopefully it won't short the oscillator and kill my 15 year old NE602, I only have two spares. Should I be afraid to do this? Does it need something to block DC current? |
