50 - 150MHz Overtone Oscillator.

Notes:

1 Y1 is a cut overtone crystal
2 Tune L1 and C2 to operating frequency
3 L2 and shunt capacitance, co. of crystal (about 6pf) should resonate to oscillator frwquency (L2 = 0.5uH at 90 MHz). This is needed to tune out effect of co.
4 C3 is varied to match output.

If you build this one, let me know at NJ95K@HOTMAIL.COM. I would love to know how it went and will place any info you have on this page. Thanks!
