Adding parallel resonant circuit across crystal, tuned slightly above crystal frequency, makes oscillator frequency increase. Some plated crystals will work better than others in this circuit; third-overtone types operating on their fundamental generally give best results. Article covers theory of operation.-L. Lisle, The Tunable Crystal Oscillator, QST, Oct. 1973, p 30-32.
